Global analysis of spatio-temporal variation in mineral nutritional quality of pepper (Capsicum spp.) fruit and its regulatory variables: A meta-analysis

Pepper (Capsicum spp.) is an important fruit vegetable worldwide, and it is a rich dietary source of minerals for human being. Yet, the spatio-temporal distribution of pepper fruit mineral composition and the factors influencing such variations at global scale remain unknown. A global meta-analysis of 140 publications providing 649, 562, 690, 811 datapoints was conducted to quantify and evaluate the nutritional quality, comprising potassium (K), magnesium (Mg), iron (Fe) and zinc (Zn), of pepper fruits and its influencing variables. The analysis showed that the global average of K, Mg, Fe and Zn content in pepper fruits was 20–25 g kg−1, 1–1.5 g kg−1, 80–100 mg kg−1, and 20–40 mg kg−1, respectively. There had been a downward trend in pepper fruit nutritional quality over the last decade, especially for Fe and Zn. And, the concentration of all these four nutrients were at lower levels in less developed regions, especially in Africa. Our results showed that the vegetable “green pepper” contains more K, Mg, Fe and Zn than the “hot pepper” used as spice. The concentration of K, Mg, Fe and Zn were increased with fruit yield but that of Fe and Zn were decreased with increase in single fruit weight. Nutritional quality was optimal at mean annual temperature of 10 ℃ − 20 ℃, and was adversely affected when mean annual precipitation was < 500 mm. Pepper fruits produced at pH 6.5–7.5 had higher fruit K concentration while acidic soils (pH<6.5) favored higher Fe and Zn concentrations. The higher soil organic matter (SOM) generally improved the nutritional quality of the pepper. Our results suggest that systematic selection of superior varieties and soil amelioration (adjusting pH and SOM) of the soil-crop system are needed to achieve higher nutritional quality of pepper fruit.

Selective deforestation and exposure of African wildlife to bat-borne viruses

Proposed mechanisms of zoonotic virus spillover often posit that wildlife transmission and amplification precede human outbreaks. Between 2006 and 2012, the palm Raphia farinifera, a rich source of dietary minerals for wildlife, was nearly extirpated from Budongo Forest, Uganda. Since then, chimpanzees, black-and-white colobus, and red duiker were observed feeding on bat guano, a behavior not previously observed. Here we show that guano consumption may be a response to dietary mineral scarcity and may expose wildlife to bat-borne viruses. Videos from 2017–2019 recorded 839 instances of guano consumption by the aforementioned species. Nutritional analysis of the guano revealed high concentrations of sodium, potassium, magnesium and phosphorus. Metagenomic analyses of the guano identified 27 eukaryotic viruses, including a novel betacoronavirus. Our findings illustrate how “upstream” drivers such as socioeconomics and resource extraction can initiate elaborate chains of causation, ultimately increasing virus spillover risk.

Trace element concentrations in seaweeds of the Arabian Gulf identified by morphology and DNA barcodes

Abstract Even though seaweeds have been considered a nutrient-rich dietary source of minerals in other parts of the world, there is little knowledge about trace element accumulation in seaweeds of the Arabian Gulf. The Arabian Gulf is of particular interest due to being an extreme environment, as it features some of the highest temperatures and salinities observed in any marine waters in the world. This study determined the minerals contents using inductively-coupled plasma-mass spectrometry (ICP-MS) in 10 of the most common seaweeds of this region (Iyengaria stellata, Padina boergesenii, Chondria sp., Feldmannia indica, Codium papillatum, Sargassum aquifolium, Ulva chaugulii, Ulva tepida and Ulva sp.) supported by morphological and molecular (DNA barcode)-based identification. The finding of U. chaugulii reported here is a new record for Kuwait. Most of the seaweeds were rich in essential minerals including Ca, Mg, Na, K, Fe and Zn and their contents were higher than those of other mineral-rich foods. Principal component analysis revealed species-specific distributions of minerals in seaweeds. U. tepida and I. stellata were found to be exceptionally rich in most of the macro- and trace elements along with low As and Se, and thus can be utilized for food and feed applications.

Ash content in fruit samples of the &lt;i&gt;Actinidia kolomikta&lt;/i&gt; genetic collection

Among the representatives of the Actinidia Lindl. genus, Actinidia kolomikta (Siebold et Zucc.) Planch. is valued as the most winter-hardy variety with high taste and dietary properties. The Federal Horticultural Research Centre for Breeding, Agrotechnology and Nursery has a live collection of Actinidia, which includes more than a hundred cultivated forms and varieties. In this study, ash content in Actinidia kolomikta fruits of 10 varieties and collection samples was studied by energy-dispersive X-ray spectroscopy using an analytical scanning electron microscope JEOL JSM6090 LA. A decreasing series was established for the accumulation of ash elements in the fruits of the studied samples: Ca&gt; K&gt; P&gt; Mg&gt; Mo&gt; S&gt; Se&gt; Zn&gt; Fe&gt; Co&gt; Si&gt; Na. In terms of accumulation of useful macro- and micronutrients, the most valuable varieties were identified. The total accumulation of macronutrients in the fruit ash ranged from 28.6 to 45.3 wt%. This indicator was the highest in the fruits of Dolgovechnaya, Uslada and Vinogradnaya (42.068–45.638 wt%). The fruits of the Uslada variety were distinguished by a high content of phosphorus (5.89), silicon (0.504), sulfur (1.34) and potassium (23.596 wt%). In terms of micronutrient accumulation, the Pamyati Kolbasinoj variety (4.904 wt%) showed the highest levels of molybdenum (3.804) and selenium (0.801 wt%). Iron accumulated more readily in the fruits of the Uslada variety (0.161), cobalt — in Nadezhda (0.157), zinc — in Vinogradnaya (0.247) and Chempion (0.195). A statistically significant positive correlation (r &gt; 0.7) was revealed in the accumulation of the following pairs of ash elements: sodium — sulfur (r = 0.70), phosphorus — potassium (r = 0.75), silicon — iron (r = 0.76), as well as molybdenum with phosphorus (r = 0.84), sulfur (r = 0.83) and potassium (r = 0.71). A statistically significant negative correlation was observed only for the accumulation of phosphorus and calcium (r = -0.71). According to the results, the fruits of the Actinidia kolomikta varieties under study can be an additional or alternative source of dietary minerals in functional food products.

DIETARY ORGANIC MINERAL INFLUENCES THE GROWTH, FEED UTILIZATION AND VERTEBRAL MINERAL CONTENT OF WILD GOLDEN RABBITFISH, Siganus guttatus

The positive effect of organic mineral as a dietary mineral source in aquafeed has been recently reported on several species. Nevertheless, the influence of organic minerals on rabbitfish has not yet been determined. The purpose of the present study was to evaluate the effects of different doses of organic mineral on growth and survival, and mineral content in vertebrae of golden rabbitfish, Siganus guttatus. Three diets were formulated containing 0.5%, 1.0%, and 2.0% organic material (OM). A control diet (OM0) did not contain OM. Instead, it was supplemented with an inorganic mineral mixture at a level of 1%. Three hundred fish were randomly selected and distributed in 12 cages to accommodate the four treatments with triplicates. The stocking density was 20 fish per cage. The initial body weight of fish used was 39.2 ± 0.3 g. Fish were fed the test diets twice a day for 150 days. A significant (P&lt;0.05) cubic effect of the treatments was detected on all dependent parameters analysis, excluding feed intake. The influence of dietary OM was not significant for feed intake, indicating that dietary OM did not negatively affect the appetite of rabbitfish. Mineral (Ca, Mg, Zn) content in the vertebrae was significantly improved when dietary OM was included in the diet up to 1% but decreased at the highest inclusion level of 2%. The optimum level of dietary OM to gain the maximum growth rate of rabbitfish was 0.49% as the reflection of the breakpoint of two regressions fitted on specific growth rate (SGR). It is concluded that dietary OM level significantly affected the growth and vertebral mineral content of golden rabbitfish. The study increases our knowledge of the benefit of utilizing dietary OM in the fish diet.

Toxic element profile of ice cream in Bangladesh: a health risk assessment study.

Ice cream is a popular frozen dairy product and a possible source of dietary minerals. However, ice cream may also contain toxic metals, which may cause several health implications. The current study aimed to determine the content of toxic elements in ice cream samples using inductively coupled plasma-optical emission spectrometry (ICP-OES) and to assess the health risks of consumers based on target cancer risk (TCR), target hazard quotient (THQ), and hazardous index (HI). The determined concentration (median, range) of all studied elements had shown a descending order of Al (9.36, 5.37-14.26) > Zn (5.94, 1.95-10.22) > Cu (1.73, 1.02-3.77) > Ni (0.95, 0.67-1.80) > Fe (0.79, 0.10-1.64) > Cr (0.43, 0.28-0.73) > Mn (0.42, 0.11-1.03) > Pb (0.34, 0.09-0.79) > Cd (0.08, 0.04-0.14) mg/kg (fresh weight). The values of THQ and HI (except 16% for children) were lower than the maximum threshold risk limit (TRL = 1.0), indicating no potential non-carcinogenic health effects might occur. Similarly, the TCR of Cr and Pb for both adults and children was within the permissible limit of 10-4-10-6, which suggested that the consumer would not experience potential lifetime carcinogenic health risks. However, the overall analyses revealed that the consumption of ice cream is almost safe for people, but the combined impact of all metals (HI) in some samples is a matter of health concern. Henceforth, regular monitoring of toxic metals in ice creams should be done to assure food safety and hygiene.

Isosmotic Macrocation Variation Modulates Mineral Efficiency, Morpho-Physiological Traits, and Functional Properties in Hydroponically Grown Lettuce Varieties (Lactuca sativa L.).

The management of mineral elements in agriculture is important for their nutritional role for plants and dietary value for humans, sparking interest in strategies that can increase mineral use efficiency and accumulation in plant food. In this work, we evaluated the effects of the isosmotic variations of the concentration on three macrocations (K, Ca, and Mg) in lettuce (Lactuca sativa L.). Our aim was to improve the nutritional components of this valuable dietary source of minerals. Using a full factorial design, we analyzed mineral utilization efficiency (UtE), leaf morphology, gas exchange parameters, phenolic profiles (through ultra-high performance liquid chromatography coupled to a quadrupole-time-of-flight (UHPLC-QTOF) mass spectrometry), and enzymatic activities in two phytochemically diverse butterhead lettuce varieties (red or green). Plants were fed in hydroponics with three nutrient solutions (NSs) with different ratios of K, Ca, and Mg. The variation of these minerals in the edible product was associated with alterations of the morphology and physiology of the leaves, and of the quality and functional properties of lettuce, with a trade-off between total accumulation and mineral UtE. Moreover, in non-limiting conditions of nutrient availability, significant mineral interactions were also present. The flexibility of the plant response to the different ratios of macrocations, and the observed large intraspecific variation, were adequate to provide mineral-specific phytochemical profiles to the edible product. Specifically, the full-red lettuce provided more interesting results in regard to the compositional and functional attributes of the leaves.

Comparative Evaluation of Tomato Hybrids and Inbred Lines for Fruit Quality Traits

Tomato is one of the most consumed fruit vegetables globally and is a high dietary source of minerals, fiber, carotenoids, and vitamin C. The tomato is also well known for its nutraceutical chemical content which strengthens human immune systems and is protective against infectious and degenerative diseases. For this reason, there has been recent emphasis on breeding new tomato cultivars with nutraceutical value. Most of the modern tomato cultivars are F1 hybrids, and many of the characteristics associated with fruit quality have additive gene action; so, in theory, inbred vigor could reach hybrid vigor. A sum of 20 recombinant lines was released from the commercial single-cross hybrids Iron, Sahara, Formula, and Elpida, through a breeding process. Those recombinant lines were evaluated during spring–summer 2015 under organic farming conditions in a randomized complete block design (RCBD) experimental design with three replications. A sum of eleven qualitative characteristics of the fruit was recorded on an individual plant basis. Results from this study indicated that the simultaneous selection of individual tomato plants, both in terms of their high yield and desired fruit quality characteristics, can lead to highly productive recombinant lines with integrated quality characteristics. So, inbred vigor can reach and even surpass hybrid vigor. The response to selection for all characteristics evaluated shows additive gene action of all characteristics measured. These recombinant lines can fulfill this role as alternatives to hybrid cultivars and those that possess high nutritional values to function as functional-protective food.

Heterosis Breeding in Eggplant (Solanum melongena L.): Gains and Provocations.

Heterosis (or hybrid vigor) results in a hybrid’s phenotypic superiority over its founder parents for quantitative and qualitative traits. Hybrid vigor is defined by mechanisms such as dominant complementation, over-dominance, and epistasis. Eggplant (Solanum melongena L.) is an essential vegetable crop and a good source of dietary minerals, vitamins, and anthocyanins, with a high oxygen radical absorbance capacity and low caloric value. Given the economic and nutritional significance of eggplants, breeding efforts focus on developing high-yielding varieties—mostly F1 hybrids—with important traits. Studies indicate the successful exploitation of heterosis in the eggplant for a considerable improvement with respect to quantitative traits. In this direction, estimating heterosis for yield-related traits could well be useful for examining the most beneficial hybrid mix with the exploitation of top-quality hybrid. This review examines the current perception of the breeding and molecular aspects of heterosis in eggplants and cites several studies describing the mechanisms. Rendering and combining recent genomics, epigenetic, proteomic, and metabolomics studies present new prospects towards the understanding of the regulatory events of heterosis involved in the evolution and the domestication of the eggplant ideotype.

226 Effect of dietary mineral source on the clearance time of porcine epidemic diarrhea virus in the saliva of commercial gilts.

Novel inorganic trace mineral sources, like hydroxychlorides (IntelliBond, Micronutrients, Indianapolis, IN), are now commercially available. Hydroxychloride trace minerals (HTM) have covalent bonds similar to organic mineral sources and better bioavailability than sulfate mineral sources (SUF). Moreover, it is well established that trace minerals like Zn, Cu, and Mn significantly influence immune function. Therefore, trace mineral source might affect how gilts respond to being acclimated to porcine epidemic diarrhea virus (PEDV). Currently, there is little commercial field research investigating the effect of mineral source on PEDV clearance from gilt saliva. Therefore, a study was conducted to determine how feeding different sources of trace minerals to developing gilts affected PEDV saliva concentrations at different time points. In the nursery, gilts were divided into two groups of at least 20,000 pigs. Once separated, 34 rooms were fed diets supplemented with Cu, Zn, and Mn hydroxychloride, and 45 rooms were fed diets supplemented with the same concentration of SUF. Mineral source, day, and their interaction were used as fixed effects. Farm was used as a random effect. Room was the experimental unit. Gilts received treatment diets at the start of the 3rd nursery phase (12.5 to 25 kg BW) and continued for 15 weeks after they were transferred to the gilt developer unit (GDU). Gilts were fed practical, industry-type diets that changed with feeding phase and were formulated to contain 15 ppm Cu, 120 ppm Zn, and 50 ppm Mn. Mineral source was the only difference between treatments. Upon arrival to the GDU, pigs were orally acclimated to PEDV (day 0) through the water line using a water medicator. Beginning at day 7, ropes were placed into each room to collect saliva. After 7 days, ropes were tested for PEDV via real-time PCR (RT-PCR). The virus was deemed clear when 32 RT-PCR cycles were required to detect PEDV. When first measured (14 days), there was a trend (P = 0.066) for HTM fed gilts to require more cycles to detect PEDV than SUF fed gilts. After 42 days, HTM fed gilts required significantly more (P < 0.05) cycles to detect PEDV. Gilts fed diets with HTM reached the clearance threshold of 32 cycles by 42 days, whereas SUF fed gilts reached that threshold one week later. In conclusion, replacing SUF with HTM reduced the time it took the immune system of commercial gilts to clear PEDV from their saliva.

Influence of dietary mineral sources on milk yield and composition of West African Dwarf Does

This study investigated the effects of different mineral nutrient sources (local potash (&ldquo;kaun&rdquo;), mineral lick and ruminant mineral premix) on milk yield and composition of West African Dwarf does. Twelve WAD goats (first parity does), weighing between 13.00&plusmn;3.79 and 14.33&plusmn;4.83 kg, were divided into four groups with three does per treatment; 0% mineral (0MC), 2% local potash (2LP), mineral lick (2ML) and mineral ruminant premix (2RMP). The experiment lasted for 180 days (150 days pregnancy, 30 days milk collection). Data collected on the milk yield and milk composition of WAD does were analysed using One-way analysis of variance (ANOVA), significant means were separated using Duncan Multiple Range Test. Result revealed that for total milk yield and daily milk yield, does in 2ML (5919.67 millilitre/animal, 197.32 millilitre/animal/day), 2LP (5852.00 millilitre/animal, 195.07 millilitre/animal/day) and 2RMP (5131.00 millilitre/animal, 171.03 millilitre/animal/day) had the highest (p&lt;0.05) values with 0MC (1642.67 millilitre/animal, 54.76 millilitre/animal/day) having the least values. For colostrum lactose, 2RMP (4.33&plusmn;0.15%) and 2PLP (4.10&plusmn;0.21%) had the highest (p&lt;0.05) values followed by 0MC (3.97&plusmn;0.27%) and 2ML (3.30&plusmn;0.25%). While, in milk total solid, 0MC (11.40&plusmn;0.35%) had the highest (p&lt;0.05) value followed by 2ML (10.43&plusmn;1.03%) and 2RMP (9.87&plusmn;0.32%) with 2LP (8.93&plusmn;0.43%) having the least values. The study concluded that for high milk yield, diets containing 2ML could be fed to does.

Evaluation of anticancer activity of water and juice extracts of young Hordeum vulgare in human cancer cell lines HT-29 and A549.

Introduction and objective. Barley (Hordeum vulgare L.) is known as a rich source of different bioactive compounds. At present, considerable attention of researchers is focused on young barley grass. It can be a good source of dietary minerals, vitamins, carbohydrates, amino acids, phenolic compounds and proteins. It is possible that the composition of chemical ingredients beneficial for health may induce an anticancer potential of young barley in human colon adenocarcinoma (HT-29) and human lung adenocarcinoma (A549) cell lines. Materials and method. Hordeum vulgare water extract (HWE) and Hordeum vulgare juice extract (HJE) were prepared. Cell proliferation and viability were examined with the use of MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and NR (neutral red) methods. Induction of necrosis was assessed by propidium iodide/Hoechst staining. Progress of the cell cycle involved in cell proliferation, apoptosis, and regulation of transcription was estimated using flow cytometry analysis. Additionally, the capability of free radical scavenging was evaluated with the DPPH assay. Results. The study revealed that extracts inhibited the proliferation of cancer cells. The NR study confirmed the low cytotoxic activity of the tested extracts to normal human colon epithelial cells (CCD 841 CoTr) and human skin fibroblasts (HSF). Furthermore, a dose-dependent cytotoxicity against HT-29 cells, but not A549 cells, has been reported. The free radical scavenging activity was observed in the case of the HWE but not the HJE. Conclusions. The obtained results indicate a cancer chemopreventive potential of young barley as a safe dietary agent in colon carcinoma.

The study aimed at determining the minor and major elements present in seeds of Moringa ovalifolia and Moringa oleifera. The seeds were air-dried after collection, then ground to a fine powder and digested with acids in a microwave system prior to analysis by inductively coupled plasma optical emission spectroscopy (ICP-OES). The concentration of different elements in M. ovalifolia seeds such as Ca, K, Fe, Ni, Cu, Mn, Co and Cd varied (P 0.05) in the concentrations of elements such Mg, Li, Ba, Si, Al, Na and Zn was observed between sites. Potasium (K) was found to be present in highest amounts at all sites with average concentration of 7938 mg/kg while Li (10.78 mg/kg) had the lowest concentration. This study showed that the content of some metals in M. ovalifolia seeds varied depending on geographical sites. Both M. ovalifolia and M. oleifera seeds are a good source of important minerals and need to be explored further for use as supplements and ready source of dietary minerals in animal and human food. Key words: Elemental analysis, Inductively Coupled Plasma Optical Emission Spectroscopy, macronutrients,

Nutrition Concerns of Insufficient and Excessive Intake of Dietary Minerals in Lactating Women: A Cross-Sectional Survey in Three Cities of China.

ObjectiveObjectives of this study were 1) to investigate the mineral intake by Chinese lactating women, 2) to explore the dietary source of minerals, and 3) the ratios between different dietary minerals.MethodsA total of 468 lactating women in 5–240 days post-partum participated in this study. Food intakes by participants were measured using one time of 24-hour dietary recall, and minerals from food were calculated based on the Chinese Food Composition Table, second edition.ResultsIn post-partum, women had inadequate food intake. 81.0% of women’s daily intake of dairy products was lower than 300g, and 97.1% of women’s daily intake of salt over 6g. For mineral intake, there were 81.8%, 59.0%, 47.6%, 45.7% and 66.8% of women’s calcium, magnesium, iron, zinc and selenium intake lower than the estimated average requirement, respectively, and 91.7% of women’s excessive intake of sodium. The calcium/phosphorus and sodium/potassium ratios were 0.41±0.26/1 and 3.13±2.89/1, respectively. Considering the dietary sources of minerals, 27.3%, 25.3% and 30.1% of iron, zinc and calcium were from animal-based food, respectively, and 60.3%, 66.1% and 58.0% of iron, zinc and calcium were from plant-based food, respectively. The phosphorus-protein ratio was 0.014±0.003/1. Lactation stage was associated with nutrient intake. Women within 30 days post-partum and the ones who live in Guangzhou had a significantly lower intake of certain minerals, while women with a high education experience had a high intake of calcium, potassium, iron and zinc. Productive age, whether obese or not, and delivery ways were not associated with mineral intakes (P all >0.05).ConclusionChinese women in three studied cities had an inappropriate food intake and resulted in both insufficient and excessive intakes of certain minerals.

Use of Oyster Processing Byproduct to Replace Fish Meal and Minerals in the Diet of Nile Tilapia Oreochromis niloticus Fry

A byproduct from processing oysters (Crassostrea iridalei) for human consumption was evaluated as a possible protein source to replace fishmeal in the Nile tilapia diet. In an 8 week-feeding trial, fish were fed 7 experimental diets containing various inclusion levels of oyster byproduct (OBP) which replaced fish meal. Diet 1 contained 0% OBP, while Diets 2-6 contained 5%, 10%, 15%, 20%, 25% OBP respectively; Diet 7 was a fishmeal-based diet with OBP as the only source of dietary minerals. The optimum amount of OBP inclusion levels producing maximal responses i.e. final average body weight (FABW), weight gain (WG), specific growth rate (SGR), food conversion rate (FCR) and protein efficiency rate (PER) was estimated using the Broken Line Model of analysis. Average optimum level was 17.0% of dietary OBP (fishmeal replacement of 63.8%). Diet 4 (15% OBP= 56.4% fishmeal replacement) resulted in statistically similar growth and feed efficiency parameters to Diets 1-3 and were closest to the estimated optimum inclusion level. Total mineral replacement by OBP (Diet 7) resulted in differing results; SGR values were statistically similar to those of the other dietary treatments; however FABW was inferior, and values for WG, FCR and PER were intermediate. In conclusion, OBP could replace as much as 63.8% by weight of dietary fishmeal and probably a large proportion of the mineral mix in the diet of Nile tilapia fry.

Physicochemical Properties of &amp;lt;i&amp;gt;Moringa oleifera&amp;lt;/i&amp;gt; Seeds and Their Edible Oil Cultivated at Different Regions in Egypt

Moringa oleifera is a plant that successfully grows recently in Egypt and has rich of nutrients seeds with valuable content of edible oil. The present study aimed at determining the physicochemical properties of moringa seeds and their extracted oil of which cultivated at different regions in Egypt. Obtained results revealed that protein, lipid, ash, fiber and total carbohydrate contents were in range of 34.51% - 36.5%, 28.62% - 30.06%, 4.22% - 5.06%, 10.92% - 12.16% and 19.00% - 20.29%, respectively. Consequently, caloric value was around 450.36 - 451.32 kcal 100 g-1 for dried moringa seeds. As confirmed, dried moringa seeds are considered as a rich source of dietary minerals. TPCs content of M. oleifera seed were ranged from 16.9 - 18.5 mg GAE g-1 dw. The anti-oxidants activity was in a range of 0.17 - 0.28 μmol TE g-1 dw (DPPH scavenging activity) and was in a range of 4.19 - 6.29 μmol TE g-1 dw (DPPH scavenging activity). The chlorophyll a, chlorophyll b, carotenoids, flavonoids and flavonols contents were ranged from 0.93 to 1.78, 4.89 to 8.41, 13.53 to 19.56 mg g-1 dw, 3.30 to 5.40 and 2.30 to 4.10 mg QE g-1 dw, respectively. Obviously, the individual essential amino acids (EAAs) and nonessential amino acids (NEAAs) recorded higher contents when compared to referenced protein. Total AA showed in triple amount in moringa protein when compared FAO standard. The acid value, iodine value, unsaponificable matter, peroxide value, refractive index, saponification value of cold pressed moringa seeds oil found to be 0.29 - 0.37 mg·g-1, 65.7 - 67.5, 0.60 to 0.74 g 100 g-1, 1.67 - 2.47 mEq/Kg, 1.4607 - 1.4613, 171.7 to 178.3 mg KOH g-1, respectively. Clearly, the unsaturated fatty acids (USFA) contents of M. oleifera edible oils were 77.14% - 84.98%, especially oleic (73.30% - 79.58%). On the contrary, the saturated fatty acids (SFA) recorded 15.00% - 22.83% where palmitic and stearic acids were the predominant SFA. The results of oil physicochemical parameters were compared with those of commercial oils. It could be illustrated that moringa seeds and its oil considered as a good source for dietary nutraceuticals and valuable characteristics for potential nutritional and technological applications.

Chemical Composition And Nutritional Evaluation Of Leea Guineensis Seed

The proximate composition, minerals, fatty acids and amino acids profile of Leea guineensis seeds were investigated. The results of the proximate analysis revealed that Leea guineensis seeds have crude protein of 22.30 ±0.45% , crude fiber of 14.38±1.20% and ash of 6.96 ±0.16%. The results also shows that Leea guineensis seeds is a good sources of dietary minerals especially potassium, phosphorus, magnesium, manganese and copper. Fatty acids profile of the seeds revealed that the seed lipids contained higher concentration of linoleic acid, oleic acid and palmitic acid. Also, amino acids profile of Leea guineensis seeds showed that it essential amino acids such as threonine, valine, isoleucine, leucne, tyrosine, phenylalanine and histidine. Leea guineensis seed is therefore considered to be a good source of essential nutrients that would be useful for both animal and human being.

Lactic acid and thermal treatments trigger the hydrolysis of myo-inositol hexakisphosphate and modify the abundance of lower myo-inositol phosphates in barley (Hordeum vulgare L.).

Barley is an important source of dietary minerals, but it also contains myo-inositol hexakisphosphate (InsP6) that lowers their absorption. This study evaluated the effects of increasing concentrations (0.5, 1, and 5%, vol/vol) of lactic acid (LA), without or with an additional thermal treatment at 55°C (LA-H), on InsP6 hydrolysis, formation of lower phosphorylated myo-inositol phosphates, and changes in chemical composition of barley grain. Increasing LA concentrations and thermal treatment linearly reduced (P<0.001) InsP6-phosphate (InsP6-P) by 0.5 to 1 g compared to the native barley. In particular, treating barley with 5% LA-H was the most efficient treatment to reduce the concentrations of InsP6-P, and stimulate the formation of lower phosphorylated myo-inositol phosphates such as myo-inositol tetraphosphate (InsP4) and myo-inositol pentaphosphates (InsP5). Also, LA and thermal treatment changed the abundance of InsP4 and InsP5 isomers with Ins(1,2,5,6)P4 and Ins(1,2,3,4,5)P5 as the dominating isomers with 5% LA, 1% LA-H and 5% LA-H treatment of barley, resembling to profiles found when microbial 6-phytase is applied. Treating barley with LA at room temperature (22°C) increased the concentration of resistant starch and dietary fiber but lowered those of total starch and crude ash. Interestingly, total phosphorus (P) was only reduced (P<0.05) in barley treated with LA-H but not after processing of barley with LA at room temperature. In conclusion, LA and LA-H treatment may be effective processing techniques to reduce InsP6 in cereals used in animal feeding with the highest degradation of InsP6 at 5% LA-H. Further in vivo studies are warranted to determine the actual intestinal P availability and to assess the impact of changes in nutrient composition of LA treated barley on animal performance.

秤量法食事記録調査より求めた小学生，大学生，高齢者のミネラル摂取量及び食品群別寄与率の比較

【目的】写真併用食事記録調査より，ミネラルを中心とした栄養素等摂取状況を明らかにし，これらのミネラルの年齢群別，摂取量別食品群別寄与率を比較し，カルシウム・鉄を多く摂る食生活と栄養素等摂取状況の関連を検討すること。【方法】写真を併用した4日間の食事記録調査を小学生72人，大学生204人，高齢者55人に行い，日本食品標準成分表2010を用いて栄養素等摂取量，食品群別摂取量，各ミネラルの食品群別寄与率を算出し，年齢群別，摂取量別に比較した。【結果】カルシウムは乳類，マンガンは穀類等，ナトリウムは調味料及び香辛料類の寄与率が高く，カリウム，マグネシウム，リン，鉄は多くの食品群が寄与率に関与していた。これらのミネラルの寄与食品群は年齢群，ミネラルの摂取量により異なった。これらのミネラルを多く含む食品を適量摂取し，摂取する食品が多様であると，ミネラル摂取が良好であり，日本人に不足しがちなカルシウム・鉄を多く摂取すると，その他の食品群や栄養素の摂取も良好であった。【結論】ミネラルを多く含む食品の適量摂取と，食品の多様性がミネラル摂取量を良好にし，カルシウム・鉄を多く摂取する食生活を心掛けることで，栄養素等摂取状況を改善させることのできる可能性が示唆された。

Genetic Variability, Inheritance and Correlation for Mineral Contents in Cabbage (Brassica Oleracea Var. Capitata L.)

Abstract Brassica vegetables are important sources of dietary minerals. However, information on the inheritance and correlation for content of mineral elements such as iron, zinc, copper, manganese, potassium, and calcium in cabbage, which is essential if the quality of this vegetable is to be improved through breeding, is not available. Therefore, the experiment was set up with seventy-one cabbage genotypes including cultivars, germplasm and F1 hybrids grown in field. Mineral composition of the genotypes tested differed highly significantly indicating the presence of adequate amount of variability. A high heritability (&gt;80%) accompanied by high genetic advance as percentage of mean (&gt;40%) for uptake and accumulation of Fe, Zn, Cu, Mn and Ca indicates the predominance of additive gene, which could be improved by hybridization followed by selection breeding approach. Nevertheless, heterosis breeding would be an imperative in increasing the K content in cabbage heads as indicated by non-additive gene action for K accumulation having high heritability (&gt;80%) and low genetic advance as percentage of mean (&lt;30%). Moreover, both additive and non-additive genes were responsible for individual head weight. A positive correlation for Fe, Zn and Mn contents with other minerals will help in simultaneous selection of mineral elements. Nevertheless, major yield contributing ‘head weight’ was negatively correlated with minerals content and emphasized the selection of smaller head size to maintain the higher minerals content in tissues of cabbage heads. Hence, assessing the heritability, inheritance and correlation for minerals would be useful in the developing mineral-rich and productive genotypes.
