Exploring Natural Alternatives to Nitrites in Pork Meat Patty: A Study on the Effects of Gromwell Root Extract and Lettuce Powder as Substitutes

The aim of this study was to assess the feasibility of substituting nitrite in pork meat patties with gromwell root extract and lettuce powder. We made pork patties with gromwell root extract and lettuce powder (control, no addition; positive control, addition of 50 ppm sodium nitrite + 0.1 % ascorbic acid ; T1, 0.3% gromwell root extract; T2, 0.1% lettuce powder; T3, 0.3 % gromwell root extract + 0.1 % lettuce powder ) and investigated whether gromwell root extract and lettuce powder could serve as nitrite substitutes. Addition of gromwell root extract and lettuce powder improved WHC and CL and storage stability. Furthermore, addition of gromwell root extract reduced lightness and yellowness and increased redness. However, it had a negative effect on the sensory evaluation of flavor, bitterness, and off odor. In conclusion, gromwell root extract and lettuce powder showed positive potential as substitutes for nitrite in pork meat patties.

Effect of adding Cynara scolymus L. (artichoke) extract to water or diet on the productive performance of broilers

The experiment was carried out in the poultry field of the Department of Animal Production/College of Agriculture/the University of Diyala from 4/9/2021 to 10/14/2021 to study the effect of adding Cynara scolymus L. )artichoke( extract to the diet of broilers. It was used as an antioxidant to show its effect on birds' productive, physiological and immune performance. In this experiment, 225 unsexed Ross 308 hybrid broiler chicks were used (one day age), with an initial weight of 44.36 g/chick. These chicks were randomly distributed from the first day of receiving them to five experimental treatments with three replicates for each treatment (15 birds/repeat). The experimental treatments were: T1 = (control treatment) provided a standard diet free of additives, T2 = Standard ration plus 75 mg/L artichoke extract, T3 = a standard diet supplemented with 150 mg/L artichoke extract, T4 = Standard ration to which 2 g/kg of artichoke extract is added, and T5 = Standard ration to which 3 g/kg of artichoke extract is added. The experiment results indicated a significant effect on product traits when adding different artichoke leaf extract powder levels to Ross 308 broiler water and diet (1-42 days). Generally, treatment T3 was significantly (P<0.05) superior in the fourth week in recording the highest average live body weight of 3170.90 g, and treatment T4 was significantly (P<0.05) in the fourth week and recorded the highest rate of weight gain. Also, treatment T1 in the first week recorded the highest rate of feed consumption, treatment T2 in the first week recorded the highest efficiency of food conversion, and treatment T3 significantly (P<0.05) and recorded the highest rate of productive evidence.

Reducing total nitrogen and dimethyl sulfide content of dry malt extract powder via spray-freeze drying method

Abstract Dry malt extract (DME) is powder prepared by dehydrating the wort, which is mainly produced by spray drying on the market. In addition, the beer industry has problems with the nitrogen content of wort, which is not easily controlled, and with the undesired volatile dimethyl sulfide (DMS), which is caused unpleasant odors in beer. In this study, DME was prepared using spray-freeze drying (SFD) technology by comparing with freeze dried DME and spray dried DME. The results show that SFD can be used as a novel engineering technique to improve the physical properties of DME having a narrow particle size distribution as well as high solubility and flowability. The freezing process was found to migrate proteins to the droplet surface by elemental analysis, and the drying process partially modified the surface protein and SFD powder fragility characteristics to achieve the purpose of reducing nitrogen content in DME.

Discrete element simulation study of mixing process of Guizhi Fuling Capsules: parameter calibration

The mixing process is a critical link in the formation of oral solid preparations of traditional Chinese medicine. This paper took the extract powder of Guizhi Fuling Capsules and Paeonol powder as research objects. The angle of repose, loose packing density, and particle size of the two powders were measured to calibrate discrete element simulation parameters for the mixing process. The discrete element method was used to calibrate the simulated solid density of Paeonol powder and extract powder of Guizhi Fuling Capsules based on the Hertz-Mindlin with JKR V2 contact model and particle scaling. The Plackett-Burman experimental design was used to screen out the critical contact parameters that had a significant effect on the simulation of the angle of repose. The regression model between the critical contact parameters and the simulated angle of repose was established by the Box-Behnken experimental design, and the critical contact parameters of each powder were optimized based on the regression model. The best combination of critical contact parameters of the extract powder of Guizhi Fuling Capsules was found to be 0.51 for particle-particle static friction coefficient, 0.31 for particle-particle rolling friction coefficient, and 0.64 for particle-stainless steel static friction coefficient. For Paeonol powder, the best combination of critical contact parameters was 0.4 for particle-particle static friction coefficient and 0.19 for particle-particle rolling friction coefficient. The best combination of contact parameters between Paeonol powder and extract powder of Guizhi Fuling Capsules was 0.27 for collision recovery coefficient, 0.49 for static friction coefficient, and 0.38 for rolling friction coefficient. The verification results show that the relative error between the simulated value and the measured value of the angle of repose of the two single powders is less than 1%, while the relative error between the simulated value and the measured value of the angle of repose of the mixed powder with a mass ratio of 1∶1 is less than 4%. These research results provide reliable physical property simulation data for the mixed simulation experiment of extract powder of Guizhi Fuling Capsules and Paeonol powder.

Soil P solubilization and plant growth promotion by a saline–alkali-tolerant P-solubilizing bacterium, Bacillus sp. DYS211

Abstract High total P content but insufficient available P in soil is an obstacle that restricts the efficient utilization of P in saline–alkali soil regions. Although saline–alkali resistant P-solubilizing bacteria (PSB) solubilize insoluble P, few studies have focused on their application in plant growth. We isolated a PSB strain, identified as Bacillus sp. DYS211, from bird droppings in saline–alkali regions and determined its growth characteristics and resistance to salt and alkalis. To investigate the effect of PSB on the germination and growth of plant seeds, we performed a potting experiment using Suaeda salsa with PSB added. The PSB strain grew rapidly in the first 12 h, and the solubilized P content from PSB reached a maximum of 258.22 mg L−1 at 48 h. Saline–alkali tolerance and P-solubilizing ability tests showed that Bacillus sp. DYS211 preferred to dissolve inorganic P, was halophilic, and had a good P-solubilizing effect at 1%–8% salinity (available P > 150 mg L−1). It exhibited good P solubilization abilities when glucose and sucrose were used as C sources or when ammonium sulfate, ammonium nitrate or yeast extract powder were used as N sources. In the growth promotion test, PSB increased seed germination, particularly under high-salinity stress, with a growth promotion of 8.33%. The PSB also improved the growth of S. salsa, including plant height and biomass (up to three times) under both saline and alkaline conditions, and the stem diameter increased under high-salinity stress. This strain demonstrates potential for vegetation restoration in saline–alkali regions.

Poplar Propolis Improves Insulin Homeostasis in Non-Diabetic Insulin-Resistant Volunteers with Obesity: A Crossover Randomized Controlled Trial.

Propolis, a natural resinous mixture rich in polyphenols, produced by bees from a variety of plant sources, has shown significant therapeutic effects and may prevent the development of certain chronic diseases like type 2 diabetes mellitus (T2DM). The objective of this study was to evaluate the effect of supplementation with standardized poplar propolis extract powder (PPEP) on insulin homeostasis in non-diabetic insulin-resistant volunteers with obesity. In this randomized, controlled, crossover trial, nine non-diabetic insulin-resistant volunteers with obesity, aged 49 ± 7 years, were subjected to two periods of supplementation (placebo and PPEP) for 3 months. Blood samples and anthropomorphic data were collected at baseline and at the end of each phase of the intervention. PPEP supplementation improved insulin sensitivity by significantly decreasing the percentage of insulin-resistant subjects and the insulin sensitivity Matsuda index (ISI-M). According to this study, supplementation with standardized PPEP for 3 months in non-diabetic insulin-resistant volunteers with obesity led to an improvement in insulin homeostasis by its effect on insulin resistance and secretion. This study suggests that poplar propolis has a preventive effect on the physiopathological mechanisms of T2DM and, therefore, that it can help to prevent the development of the disease.

Preparation of Semi-Solid Dosage Forms Containing Psidium Guava Leaves Extract as Antimicrobial Preservative

Guava leaves extract has several medicinal activities as antimicrobial, antioxidant, anti-cancer and anti-inflammatory. Several studies have been proposed to use guava leaves extract in several preparations. However, applying guava leaves extract as a preservative in a pharmaceutical product has not been studied previously. In the present work, Guava leaves extract was used as natural preservative instead of chemical ones (methyl and propyl paraben). Guava leaves were extracted with ethanol 95% as extraction solvent with a percentage yield of 20%. This extract was tested by HPLC; several phenolic compounds were detected. To determine the ability to use this extract as a preservative, antimicrobial effectiveness test (preservative efficacy test) was conducted for extracted powder in purified water at different concentrations (0.5, 1.0, 1.5, and 2.0 % w/w), against three bacteria, one gram-positive (S. aureus), two gram-negative (P. aeruginosa, E. coli) and two fungi: one yeast (Candida albicans) and one mold (Aspergillus (Niger) brasiliensis). Results showed that 2% was effective and passed the test of preservative effectiveness test; this concentration was used in semi-solid pharmaceutical products. For this purpose, six different preparations (Ketoconazole shampoo, Clotrimazole Cream, Permethrin Cream, Gentamycin Cream, Ibuprofen gel, Indomethacin emulgel) were used. Chemical preservative was replaced by natural one (guava leaves extract powder) to serve as a preservative. Three out of the six preparations (Ketoconazole shampoo, Clotrimazole Cream, Ibuprofen gel,) passed preservative efficacy test. These preparations were fully checked-up by chemical (drug content,) physical (odor, physical appearance) and biological test (total count test) for three months at accelerated conditions. These results confirmed that these pharmaceutical preparations were stable and effective. As a conclusion Guava leaves extract can be used at 2% as natural preservative instead of chemical ones which have adverse side effects on human health.

Extraction of gymnemic acid from Gymnema inodorum (Lour.) Decne. leaves and production of dry powder extract using maltodextrin

The aim of the present study was to maximize the extraction of gymnemic acid (GA) from Phak Chiang Da (PCD) leaves, an indigenous medicinal plant used for diabetic treatment in Northern Thailand. The goal was to overcome the low concentration of GA in the leaves, which limits its applications among a larger population and develop a process to produce GA-enriched PCD extract powder. The solvent extraction method was employed to extract GA from PCD leaves. The effect of ethanol concentration and extraction temperature were investigated to determine the optimum extraction conditions. A process was developed to produce GA-enriched PCD extract powder, and its properties were characterized. In addition, color analysis (L*, a*, and b*) was performed to evaluate the overall appearance of the PCD extract powder. Antioxidant activity assay was conducted to assess the ability of the PCD extract powder to neutralize DPPH free radicals. The results showed that the concentration of 50% (v/v) ethanol at 70 °C for 2 h resulted in a higher GA concentration of 8307 mg/kg from dried PCD leaves. During the drying process, the use of maltodextrin at a concentration of 0.5% (w/v) was found to produce PCD extract powder with the maximum GA concentration. The color analysis revealed that the PCD extract powder had a dark greenish tint mixed with yellow. The antioxidant activity assay showed that 0.1 g of PCD extract powder was able to neutralize 75.8% of DPPH free radicals. The results concluded that PCD extract powder could potentially be used as a source of nutraceuticals or as a functional food ingredient. These findings suggest the potential value of GA-rich PCD extract powder in various applications in the pharmaceutical, nutraceutical, or food industries.

Evaluating and comparing geochemical sampling protocols in dinosaur eggshells: refining Cretaceous ecosystem research

The geochemical signatures of dinosaur eggshells represent well-established proxies in paleoenvironmental and paleobiological research. The variable sampling procedures reported in the literature, however, deserve attention. In order to evaluate the impact of different sampling methodologies on carbon and oxygen isotope and elemental concentrations, grinding was contrasted with drilling to extract powder samples from eggshell fragments collected at several locations. Eggshell data were further contrasted with surface materials, encasing matrix and compared with independent proxies using petrographic and elemental techniques. Iron and manganese elemental concentrations revealed an enrichment sequence depending on the sampling strategy for the same eggshell fragment. This pattern can be mistaken for a variable state of preservation. In contrast, carbon and oxygen isotope values exhibited only subtle differences and lacked clear trends. This suggests that isotope data are less susceptible to different methodological approaches. It is shown that drilling offers a wider range of possibilities compared to grinding (e.g., faster and less destructive). Additionally, drilled powder samples can confidently be used for elemental and isotope analysis, excluding contamination, thus providing a more accurate set of proxy data from eggshell archives.

Correlations of kratom (Mitragyna speciosa Korth.) tea bag preparations and reported pharmacological effects

Ethnopharmacological relevanceThe use of herbal tea infusions is widespread in ethnomedicine throughout the world. One such ethnobotanical is kratom (Mitragyna speciosa Korth., Rubiaceae) which has gained considerable interest as an herbal supplement in recent years in the West beyond its native Southeast Asia. Traditional, kratom leaves are either chewed fresh or made into a tea infusion to treat fatigue, pain, or diarrhea. However, dried kratom leaf powder and hydroalcoholic extracts are more commonly used in Western countries, raising the question of exposure to kratom alkaloids and related effects. Aim of the studyA specific kratom tea bag product was analyzed for mitragynine content using tea infusion preparation and methanolic extraction. Consumers of both the tea bag product and other kratom products completed an online anonymous survey to determine demographics, kratom use patterns, and self-reported beneficial and detrimental effects. Materials and methodsKratom tea bag samples were extracted using pH-adjusted water or methanol and analyzed using an established LC-QTOF method. A modified kratom survey was distributed to consumers of the kratom tea bag products and other kratom products over a 14-month period. ResultsTea infusion extraction of tea bag samples resulted in lower mitragynine levels (0.062–0.131% (w/w)) compared to methanolic extraction (0.485–0.616% (w/w)). Kratom tea bag consumers did report similar, although often milder beneficial effects compared to consumers using other kratom products. Overall self-reported health was better among kratom tea bag consumers whereas improvement of a diagnosed medical condition was less in tea bag consumers compared to those using other kratom products. ConclusionsTraditional tea infusions of Mitragyna speciosa dried leaves provide benefits to consumers despite substantially lower mitragynine content. These effects may be less pronounced but indicate that tea infusions provide a potentially safer formulation compared to more concentrated products.

The prevalence of dental caries in Indonesia is still high. One of the dental caries treatments is direct restoration. Biomaterial, often used as a restorative material, is glass ionomer cement which has a silica content of 35%. Silica is found in Penaeus monodon shells which have been a waste of production. This research aims to study the characteristic of Penaeus monodon shell powder extracts as candidates for dental materials restoration. The research sample used was Penaeus monodon shell powder extract which was then carried out by a depigmentation process by mixing acetone 1:10 (w/v) ≤ 20 hours. Samples were tested with the XRD test (x-ray diffraction). SEM assessment was performed to evaluate the morphology of the particle. Data were analyzed using Mann-Whitney. The result demonstrated a significant silica content in Penaeus monodon shell powder extract before and after the depigmentation process with a p-value of 0,00 (p0,05). The depigmentation process can decrease silica content in Penaeus monodon shell powder extract. There was a different comparison of silica content in Penaeus monodon shell powder extract before and after depigmentation as a candidate for dental materials restoration.

The Effect of Microwave-Assisted Extraction Temperature and Material Ratio on the Characteristics of Pandan (Pandanus amaryllifolius Roxb.) Leaf Extract

Fresh pandan leaf fragrance has been applied to enhance the aroma of many traditional foods. However, the fresh leaf has a limited shelf life—only 1 day after harvest. Therefore, pandan extract, either in liquid or powdered form, can be utilized as an alternative aromatic component in food production. The purpose of this study was to determine the effect of extraction temperatures (50, 60, and 70°C) utilizing microwave-assisted extraction (MAE) and the ratio of pandan leaf as material to ethanol as solvent (1:3, 1:7, and 1:11) on the characteristics of pandan extract in liquid form. The study found that the properties of pandan extract treated at MAE 60°C with a material-solvent ratio of 1:7 were the best among all treatments. The pH of this liquid pandan extract was 5.31, the antioxidant activity was 32.86 ppm, and the chlorophyll content was 7.76 mg/L. The powdered pandan extract generated by drying the liquid pandan extract using a spray dryer and adding maltodextrin had properties such as water activity 0.45, solubility 96.09%, solubility rate 0.01 g/s, color L 85.65, a* -6.68, b* 8.51, yield 3.88%, and was detected to contain 0.17% of the aromatic compound 2-acetyl-1-pyrroline. Powdered pandan extract has the potential to be developed as an aromatic food additive. Panelists liked the kue lumpang, a traditional cake consisting mainly of rice flour and coconut milk, which is made by adding 1% pandan leaf extract powder.

Effect of Adding Thymus leptobotrys on Extra Virgin Olive Oil’s Quality and Physicochemical Parameters

The present study aimed to evaluate the changes in extra virgin olive oil (EVOO) after enrichment treatments with Thymus leptobotrys, a Moroccan endemic aromatic plant. The EVOO sample was supplemented with two materials obtained from the aerial parts of T. leptobotrys: powder (2.5 and 5%) or essential oil (100 and 200 ppm). The chemical composition analysis of T. leptobotrys extracts (essential oil and powder methanolic extract) allowed the determination of its phenolic profile. Quality parameters (acidity, peroxide value, and specific extinction coefficients), color, fatty acids composition, minor components (pigments and phenol), and Rancimat oxidative stability of the control and enriched oils were measured. Rosmarinic acid and thymusin were the main identified compounds in the powder; thymusin was identified for the first time in the essential oil where it was predominant. Generally, the enrichments did not downgrade the oil from its initial category (EVOO), according to quality indexes. Adding T. leptobotrys to EVOO, especially the essential oil, enriched its phenolic profile by allowing the migration of thymusin, a lipophile flavone, without affecting its quality parameters or color.
