Comparative Nutritional Analysis of Zest and Pulp in Red and Yellow Grapefruit Varieties

The global cultivation and considerable demand for citrus fruits has given them a prominent place among fruit crops. With them being known for their virtues, health benefits, and characteristic aroma and taste, grapefruits have been accepted as an important food in our diets. Indeed, they play a key role in providing the nutrients to support good health. In this context, we sought to identify the nutritional characteristics of two varieties of grapefruit (citrus paradisi), namely yellow and red. We therefore investigated the water, protein, fiber, total sugar, and fat contents in the zest and pulp of these two species based on international food standards. We also quantified the various saturated and unsaturated fatty acids through gas chromatography. Our results revealed an interesting richness in these grapefruit varieties in terms of factors like total sugar, proteins, and fat, particularly in the peel, as well as a high-water content and energy value. Several fatty acids were also identified, mainly palmitic, oleic, and linoleic acids, which are highly sought after for their therapeutic benefits. This nutrient density highlights the value of these fruits and demonstrates that promoting its consumption can help improve human health and quality of life. This assortment of nutrients found in our samples, as well as the abundance of phenolic compounds already noted in other research studies, highlight this fruit and show the importance of its various parts - peel and pulp - in improving quality of life and human mental and physical health.

Higher maternal bread and thiamine intakes are associated with increased infant allergic disease.

A mother's diet during pregnancy may influence her infant's immune development. However, as potential interactions between components of our dietary intakes can make any nutritional analysis complex, here we took a multi-component dietary analysis approach. Nutritional intake data was collected from 639 pregnant women using a validated semi-quantitative food frequency questionnaire to reflect their dietary intakes during 32-36 weeks of gestation. To investigate their dietary intake pattern, we calculated Dietary Inflammatory Index scores. Maternal consumption of 12 food groups, 20 individual whole foods, and 18 specific nutrient intakes, along with any vitamin and mineral supplementation, were determined. Infant outcomes included eczema, allergen sensitization, and IgE-mediated food allergy. Regression-based analyses with covariates adjustment were applied. Women with higher white bread consumption were more likely to have an infant with doctor-diagnosed eczema (adjusted relative risk [aRR] 1.16; 95% CI 1.08, 1.24; p < .001) and IgE-mediated food allergy (aRR 1.14; 95% CI 1.02, 1.28; p = .02). Higher maternal intakes of fiber-rich bread (aRR 1.14; 95% CI 1.04, 1.25; p = .01) and legumes (aRR 1.11; 95% CI 1.02, 1.21; p = .02) were also associated with infant doctor-diagnosed eczema. Higher maternal thiamine intakes were associated with increased parent-reported infant eczema (aRR 1.08; 95% CI 1.03, 1.12; p < .001). In Australia, where bread flour is fortified with thiamine, we identified consistent links between higher maternal thiamine-rich diets and increased risk of infant eczema and food allergy. Our results highlight a need for further investigation of potential effects of high thiamine exposures on immune development, especially in-utero.

Nutritional and phytochemicals analysis of high‐altitude common bean (Phaseolus vulgaris L.) cultivars of Nepal

AbstractThe common bean, Phaseolus vulgaris L., is an important legume grown in all parts of Nepal to supply dietary protein for humans and livestock. They are rich in a variety of bioactive compounds and thus possess health‐promoting effects in the prevention of chronic diseases, including cancer, cardiovascular diseases, obesity, and diabetes. The present study examined the nutritional and proximate composition and screened the bioactive compounds present in beans grown in the high‐altitude regions of Nepal. The analysis of 18 beans indicated the moisture (6.48%–8.83%), crude protein (17.39%–23.54%), carbohydrate (58.74%–66.37%), crude fat (0.78%–1.58%), crude fiber (3.36%–4.75%), total ash (3.33%–4.69%), and total energy (340.24–350.16 kcal/100 g). The results showed that the common beans were also good sources of nutritionally important minerals, including copper (2.72–8.77 mg/kg), calcium (843.86–2763.62 mg/kg), iron (38.93–73.69 mg/kg), magnesium (1540.63–2083.52 mg/kg), sodium (205.91–695.81 mg/kg), potassium (13,560.21–16,957.05 mg/kg), and zinc (19.80–31.00 mg/kg) on a dry weight basis. Quantification of bioactive compounds revealed the highest concentration of total phenolic content (TPC) in the beans from Jumla (5.96 mg GAE/g) than Dolakha and Darchula. However, the total flavonoid content was higher in Dolakha beans (3.47 mgQE/g). The EP‐15‐03FB landrace from Jumla was superior in terms of protein, phytochemical, and TPC. The results of this study will provide valuable information on the nutritional and phytochemical contents of beans and serve as a basis for further utilization of common beans.

The technology of cooking falafel with high biological value for vegans

The article presents the results of scientific research on the possibility of increasing the biological value of falafel dishes for vegans through the use of flax seeds and blueberry extract. Vegan nutrition analysis in Ukraine shows that dishes for this population group are mostly deficient in biologically active substances. One way to solve this problem is to develop dishes for vegans using raw plant materials with a high content of biologically active substances. The chemical composition of flax seeds and blueberry extract is analysed in terms of using these products for vegan cuisine. The feasibility of using flax seeds and blueberry extract to increase the biological value of the falafel vegan dish was proven. The feasibility of replacing vegetable oil and a fraction of wheat flour to optimise the vitamin-mineral composition of falafel was determined. Based on the organoleptic evaluation of the control and test samples, the optimal ratio of falafel ingredients was established: 2.5% dry blueberry extract and 7.5% flax seeds per 100 g of the dish. The falafel chemical composition with the addition of flax seeds and blueberry extract was studied compared to the control sample. According to the research results, the technology of cooking falafel for vegans with an increased content of biologically active substances was developed. Based on the data obtained, it can be concluded that the developed dish will enrich vegan nutrition with deficient biologically active substances. The social effectiveness of the developed technology of cooking falafel is to expand the range of vegan dishes. The developed dish can be recommended for the nutrition of fasting people. It is advisable to use the technology developed to cook falafel in restaurants.

The Growth Performance and Nutrient Composition of Black Soldier Fly (Hermetia illucens) Larvae Fed Slaughtered Bovine Blood.

The disposal of slaughterhouse blood poses significant environmental challenges due to its biological instability and high nutrient content. We used a gradient of 10% blood increments (0-100%) to feed BSFL, and the correlation between the proportion of bovine blood and the BSFL weight gain, mortality rate, fatty acid content, and amino acid content was researched. Results indicate a positive correlation between the bovine blood content and BSFL mortality, with survival rates above 95% for blood proportions below 60%. Larval weight exhibited a negative correlation as the bovine blood content increased. Nutritional analysis revealed that the crude protein content in BSFL increased proportionally with bovine blood (14.75-25.45 g/100 g), while the crude fat content decreased correspondingly (10.70-4.66 g/100 g). The sugar content remained relatively constant across groups. Fatty acid analysis showed increased levels of C16:0, C14:0, and C16:1 and decreased levels of C18:1, C18:2, and C18:3 with higher bovine blood contents. The amino acid content generally increased with higher blood proportions. This study highlights the bioconversion potential of BSFL for bovine blood and underscores the impact of protein, lipid, and sugar concentrations in feed on BSFL growth. These findings provide valuable insights for utilizing slaughterhouse waste in BSFL rearing, contributing to the development of more sustainable waste management and animal feed production methods.

The conclusion of this study shows a significant decline in children's nutritional status in disaster-affected areas compared to unaffected areas. Prompt action and sustained recovery efforts are crucial to address the long-term impacts on children's growth and nutrition

Nutritional Quality Analysis and Classification Detection of Buckwheat in Different Harvest Periods.

For buckwheat, the optimal harvest period is difficult to determine-too early or too late a harvest affects the nutritional quality of buckwheat. In this paper, physical and chemical tests are combined with a method using near-infrared spectroscopy nondestructive testing technology to study buckwheat harvest and determine the optimal harvest period. Physical and chemical tests to determine the growth cycle were performed at 83 days, 90 days, 93 days, 96 days, 99 days, and 102 days, in which the buckwheat grain starch, fat, protein, total flavonoid, and total phenol contents were assessed. Spectral images of buckwheat in six different harvest periods were collected using a near-infrared spectral imaging system. Four preprocessing methods (SNV, S-G, DWT, and the normaliz function) and three dimensionality reduction algorithms (IVSO, VCPA, VISSA) were used to process the raw buckwheat spectral data, and the full and eigen spectra were established as a random forest (RF). Random forest (RF) and Least Squares Support Vector Machine (LS-SVM) classification models were used to determine the full and eigen spectra, respectively, and the optimal model for the buckwheat single harvest period was determined and validated. Through physical and chemical tests, it was concluded that the 90-day harvest buckwheat grain protein, fat, and starch contents were the highest, and that the total flavonoid and total phenolic contents were also high. The SNV preprocessing method was the most effective, and the feature bands extracted using the IVSO algorithm were more representative. The IVSO-RF model was the best discriminative model for the classification of buckwheat in different harvest periods, with the correct rates of the training and prediction sets reaching 100% and 96.67%, respectively. When applying the IVSO-RF model to the buckwheat single harvest period to verify the classification, the correct rate of the training set for each harvest period reached 96%, and that of the prediction set reached 100%. Near-infrared spectroscopy combined with the IVSO-RF modeling method for buckwheat harvest period detection is a rapid, nondestructive classification method. When this was combined with physical and chemical analyses, it was determined that a growth cycle of 90 days is the best harvest period for buckwheat. The results of this study can not only improve the quality of buckwheat crops but also be applied to other crops to determine their optimal harvest period.

Utilizing RT-DETR Model for Fruit Calorie Estimation from Digital Images

Estimating the calorie content of fruits is critical for weight management and maintaining overall health as well as aiding individuals in making informed dietary choices. Accurate knowledge of fruit calorie content assists in crafting personalized nutrition plans and preventing obesity and associated health issues. In this paper, we investigate the application of deep learning models for estimating the calorie content in fruits from digital images, aiming to provide a more efficient and accurate method for nutritional analysis. We create a dataset comprising images of various fruits and employ random data augmentation techniques during training to enhance model robustness. We utilize the RT-DETR model integrated into the ultralytics framework for implementation and conduct comparative experiments with YOLOv10 on the dataset. Our results show that the RT-DETR model achieved a precision rate of 99.01% and mAP50-95 of 94.45% in fruit detection from digital images, outperforming YOLOv10 in terms of F1- Confidence Curves, P-R curves, precision, and mAP. Conclusively, in this paper, we utilize a transformer architecture to detect fruits and estimate their calorie and nutritional content. The results of the experiments provide a technical reference for more accurately monitoring an individual’s dietary intake by estimating the calorie content of fruits.

Bioactive profiling of two varieties of Indian legumes: adzuki and mung beans

SummaryNutritional benefits of legumes make them an important part of sustainable diets. They are rich not only in dietary fibres, proteins, and micronutrients but also in the bioactive compounds that can exhibit various biological activities. In the present study, we aimed to investigate the nutritional analysis, phytochemical composition, and in vitro anti‐obesity activity of two varieties of legumes indigenous to India namely, adzuki beans (Vigna angularis) and mung beans (Vigna radiata). GC–MS, UHPLC‐QTOF‐MS, ICP‐MS analyses were done for bioactive compounds, fatty acids, macro‐elements, micro‐elements, protein, and non‐proteinogenic amino acids. GC–MS analysis showed that the major constituents identified were hydrocarbons, fatty acids, and terpenes, while the presence of various secondary metabolites, macro‐ and micro‐nutrients were detected using UHPLC‐QTOF‐MS and ICP‐MS, respectively. FAME analysis revealed a higher concentration of linoleic acid in adzuki beans, which is nutritionally beneficial for human consumption. Amino acid profiling revealed the presence of essential, non‐essential, and non‐proteinogenic amino acids. Further, adzuki beans and mung beans were screened for cytotoxicity on 3T3‐cell line and it was observed that adzuki beans were less cytotoxic as compared to mung beans. Adzuki beans showed higher HMG‐Co‐A reductase enzyme inhibition activity (60%) as compared to mung beans (2.79%). The results indicate that these two legumes are a very good source of bioactive metabolites and can be developed into novel cholesterol‐lowering and anti‐obesity functional foods.

The increasing incidence of resistance extended spectrum-beta lactamase (ESBL) producing Klebsiella pneumonia become worldwide issue. The current study aimed to determine the genomic diversity of ESBL-producing K. pneumoniae in milk samples collected from cows with mastitis as well as their antibiotic sensitivity profiles and genetic identification in Peshawar, Pakistan. The california mastitis test (CMT) was initially used to verify the presence for mastitis in 700 collected milk samples. The molecular identification of the 16SrRNA gene confirmed 120/700 (17.14 %) propagation of K. pneumonia. Out of these isolates MDR ESBL-producing isolates were 60/120 (50 %). The lactose were found (M = 3.96 ± 0.28, SD = 2.19), followed by fats (M = 3.12 ± 0.11, SD = 0.90), protein (M = 5.97 ± 0.24, SD = 1.84), sodium (M = 55.74 ± 2.07, SD = 15.81), potassium (M = 138.5 ± 1.53, SD = 11.71), chloride (M = 0.74 ± 0.03, SD = 0.24), calcium (M = 10.27 ± 0.31, SD = 2.42), and chlorine (M = 2.80 ± 0.22, SD = 1.70), respectively. Amikacin (80 %), ceftazidime (71 %), and tetracycline (71 %) were shown to be the most effective antimicrobials against all of the isolates. The occurrence of the blaSHV gene was observed at 56.00 % whereas the blaTEM gene and blaCTX-M gene were 36.00 %, and 30.00 %. The distribution of blaCTX-M subgroup genes was followed by blaCTX-M-1 (38.00 %), blaCTX-M-9 (22.20 %), and blaCTX-M-15 (61.10 %). Co-occurrence of blaCTX-M+ blaSHV was (15.00 %), blaCTX-M+ blaTEM were (6.60 %), and blaSHV + blaTEM were (10.00 %), respectively. The inappropriate, prolonged and common use of antibiotics may apply selective pressure for propagation and the occurrence of resistant isolates.

Application of Highly Digestible Fermented Corn Protein Powder in Fecal Low-Odor Adult Dog Feed

This study aimed to develop fecal low-odor adult dog feed using processed corn protein powder as the primary raw material and evaluate its effectiveness through feeding experiments. The objectives included analyzing the fundamental nutritional indicators, comparing the quality of fecal low-odor adult dog feed with commercially available dog feed, and assessing the changes in the eating behavior, physical condition, and physiological and biochemical indicators before and after feeding on the fecal low-odor adult dog feed. This study involved formulating dog feed using processed fermented corn protein powder and conducting nutritional analyses to compare moisture, crude protein, ash, crude fat, and starch contents. Physical properties such as hardness and cohesion were also evaluated. Feeding experiments were conducted with adult dogs to monitor the changes in the eating behavior and physical condition. Physiological and biochemical indicators, including ammoniacal nitrogen and putrefactive odor in feces, were measured both before and after feeding to assess the impact of the fecal low-odor adult dog feed. The analysis showed no significant difference in moisture (p &gt; 0.05), crude protein (p &gt; 0.05), ash (p &gt; 0.05), crude fat (p &gt; 0.05), and starch (p &gt; 0.05) contents between the fecal low-odor adult dog feed and commercially available dog feed. Similarly, no significant difference was noted in the hardness (p &gt; 0.05) and cohesion (p &gt; 0.05) between the two types of dog feed. Both types of dog feed contained rich volatile compounds with varying compositions. The commercially available dog feed had a sour odor, whereas the fecal low-odor adult dog feed had a barbecue and resin-like smell. After feeding with the fecal low-odor adult dog feed, the liquid nitrogen content significantly decreased (p &lt; 0.01). Also, the indole content, a major contributor to fecal odor, based on the data, decreased after feeding.

Effect of storage on physicochemical properties, bioactive compounds and sensory attributes of drinks powder enriched with pumpkin (cucurbita moschata L.)

Pumpkin is an imperious vegetable and a large part of the pumpkin flesh goes unused resulting from pumpkin processing, so it needs to be processed properly to be used. The current study's goal was to prepare a drink powder enriched with pumpkin report the impact of storage on bioactive compounds and physicochemical characteristics of drink powder, and also evaluate the sensory properties of beverages prepared from drink powder. The powders were formulated and evaluated based on their physical properties, proximal compositions, minerals, phenolic compounds, and antioxidant ability as measured by DPPH (2,2-Diphenyl-1-picrylhydrazyl), FRAP (Ferric Reducing Antioxidant Power), and ABTS (2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic) acid). Drink powder was made with a mixture of ingredients that were substituted with pumpkin pulp and seed powder in the proportions of 50:50 (S1), 20:30 (S2), 30:20 (S3), and 40:10 (S4). A sensory evaluation was carried out to select the most accepted combination. The most accepted product was subjected to nutritional analysis and storage studies, which were taken as criteria for good quality. Sample S3 had the highest protein, fat, fiber, and ash content while sample S1 had the highest carbohydrate content. It was also observed that enrichment with pumpkin powder enhanced the Mg, P, and Fe content of the drink powder. However, sample S1 had the highest DPPH radical scavenging ability, total phenolic content, and FRAP ability. During storage, a significant increase in moisture content, total sugar, and reducing sugar while a significant decrease in protein, fat, ash, fiber, and titratable acidity was observed. In addition, carotenoids, vitamin C, and antioxidant properties showed significant decreases during long-term storage at ambient temperature. Furthermore, sensory analysis was performed on pumpkin powder beverages, and based on results the color and texture of the drinks were not affected as the pumpkin powder content was increased. The drinks with 20 % pumpkin pulp and 30 % seed powder (S2) obtained the highest score for texture, taste, and overall acceptability assessed. However, the S1 and S3 are the best instances due to their better nutritional content. Hence, the drink powder that utilizes pumpkin may be an efficient means to preserve pumpkin and conserve its bioactive ingredients. In conclusion, pumpkin powder can be successfully incorporated into powdered drinks or other traditional products and also it is recognized as an excellent food source to meet daily nutritional needs.

In this study, "Honghu White Lotus", "Red Lotus (HH)", "Hunan Cunshan Lotus (CS)", "Wuyi Xuanlian", "Space Lotus 36", "Fujian Jianning White Lotus (JB)", "Jiangsu Yangzhou Lotus (JY)", and "Suzhou Dongshan Lotus" were selected as experimental subjects. The lotus seed flesh and lotus plumule of each cultivar were selected for nutritional quality and functional active substance analyses. Comparing different cultivars of lotus seeds, the protein and crude fat contents of JY flesh were the highest at 65.59 mg/g and 13%, respectively. The VC content of JB flesh and lotus plumule is the highest at 41.56 mg/g and 204.29 mg/g, respectively. JB flesh has the lowest soluble sugar content, at 17.87 mg/g, while HB's lotus plumule and flesh have the highest content, at 33.67 mg/g and 29.62 mg/g, respectively. There was no significant difference in the crude fat content of the flesh and lotus plumule among the eight cultivars. TK flesh and lotus plumule have the highest amylose content, at 23.67 mg/g and 76.81 mg/g, respectively. Among them, the total starch content of JB (476.17 mg/g) was relatively high, whereas its amylose content was only 26.09 mg/g. Lower amylose content makes it less prone to aging. The total phenolic and flavonoid contents of the JY lotus plumule were the highest, at 18.64 and 21.04 mg/g, respectively. The alkaloid content of CS, HH, and JY was relatively high at 20.01, 19.29, and 18.68 mg/g, respectively. These can provide a consultation for the estimation and processing of the nutritional quality of different lotus seeds.
