Experience into the Interfacial Lewis Acid-Base Twos within CeO2 -Loaded CoS2 Electrocatalysts regarding Alkaline Hydrogen Development.
The most popular research hot spots in this field were food safety policy integration and public-private partnership of food safety governance. Lower- and middle-income countries focused more on food supply and food system design, and regrettably not on food safety. Higher-income countries cared more about food safety and food nutrition. Besides, researchers of higher-income countries also concentrated on consumers' voices in participating in food safety governance. Food safety co-governance, online food governance, the willingness to buy safe food, and food safety governance under pandemics were considered as future research directions.‏In this study, the production of emulsion-type sausage by replacement of 20% to 40% KCl plus 1% or 2% yeast extract instead of NaCl was studied. The physical, chemical, microbiological, and sensory properties of the samples were analyzed up to 28 days of storage. The sample sausages were approved by the panelists. selleck chemical The physical, chemical, and microbiological properties of emulsion-type sausages were not considerably influenced by these changes. The 40% replaced salt by KCl showed a similar property rather than the regular sausages. The aroma and taste of the sausages improved by using yeast extract. In addition, the adverse flavors resulted from adding KCl were excluded by adding the yeast extract. As a result, production of healthy emulsion-type sausages (having 40% lower NaCl) with acceptable sensory qualities was introduced.α-Dicarbonyl compounds (α-DCs) are a class of compounds generated during the thermal processing of food. Due to the high reactivity, α-DCs were endowed with the ability to react with food components thus lowering nutrition value and even leading to a potential risk for food safety. In this study, methylglyoxal (MG), the most abundant α-DCs, was selected to investigate the alteration effects on the structure and digestibility of α-lactalbumin (αLA) under thermal processing (60-100°C). The results showed that the modification degree of αLA by MG increased with the rise of processing temperature, accompanied by the significant changes in molecular weight, intrinsic fluorescence, and secondary structures of αLA. High-resolution mass spectrometry analysis identified that lysine (Lys) and arginine (Arg) are the modification sites, and Nε-(carboxyethyl)-L-lysine is the main modification type. Since the Lys and Arg are also the cleavage sites of trypsin, the digestibility of MG modified αLA (MG-αLA) by trypsin correspondingly decreased with an increase of processing temperature. The reacted Lys and Arg residues, and the protein-bound AGEs were quantified, and the contents were found to be highly dependent on the temperature.The small outbreaks of listeriosis as one of the leading causes of food poisoning-associated deaths occur more than previously reported. In current study, the growth ability of Listeria monocytogenes strains isolated from different sources of food and human origin was measured under salt stress (0.5%, 2.5%, 5%, 7.5%, and 10%) and acid environments (pH = 6.64 and 5.77) for 96 hr by using a Bioscreen C microbiology reader at 37°C. In further steps of this study, after analysis of constituents of Zataria multiflora Boiss. essential oil (ZMEO), the sensory evaluation of the treated fish meat with ZMEO was performed. Then, the fish isolate of L. monocytogenes was exposed to sensory acceptable and subminimum inhibitory concentrations (subMICs) of ZMEO in fish broth and minced fish meat during incubation at abuse (12°C), room (22°C), and optimum (37°C) temperatures for 48 hr. The MIC of NaCl against four strains of L. monocytogenes was 10% at 37°C. The maximum optical densities (ODs) and under curve areas (AUC) of growth patterns in higher pH value and lower contents of NaCl followed the order of 21C > 6F > 66C > 22C of L. monocytogenes strains, while the lag time was prolonged in the reverse order. The maximum OD, growth, and lag times of samples treated with higher contents of NaCl and lower pH value were affected in a different order. The organoleptic evaluation showed that the fish meat treated with less than 0.5% of ZMEO was sensory acceptable. The population of L. monocytogenes remained relatively constant at the inoculation level of 107 cfu/ml (or g) at 12°C in broth and minced fish mediums. The inhibitory antilisterial activity of essential oil as an extensive-used plant for food and pharmacological applications is negligible due to possible adverse sensory and toxic effects at relevant high doses.Today, the lack of a proper nutritional formulation of the diet for soldiers is well felt. In this study, a newly formulated food supplement (FFS) was designed to supply all essential nutrients like protein, carbohydrate, oil, fat-soluble vitamins, and minerals, and Lepidium sativum L. seed (shahi) gum and Amygdalus scoparia Spach (zedo) gum were applied to FFS to promote physicochemical and sensory properties of FFS. The samples were developed by preparing emulsion including meat powder (45.0 g/100 g), soybean powder (25.0 g/100 g), and plant oils (15.0 g/100 g). Iron, zinc, and fat-soluble vitamins (A, D, E, and K) were also added to the formulation, and response surface methodology was used to optimize the effects of shahi and zedo gum at 0.5, 1.0, and 2.0 g/100 g in FFS. The results showed that using hydrocolloids in appropriate amounts enhanced the sensory properties of FFS. Hydrocolloids protected the moisture content of FFS samples and also decreased the reduction of vitamins and minerals during 14 days of storage at 4°C. The hydrocolloids improved the color indices and intrinsic viscosity of samples. The results of this study recommend the use of 1.26 g/100 g of shahi gum and 0.95 g/100 g of zedo gum to produce formulated food supplement for soldiers. This formulation supplies calories and provides some of the essential vitamins and food components to the body.Ficus species have been used as a typical component in food and folk medicine in Asia for centuries. However, little is known regarding the bioactivity and genotoxicity of the recently identified Ficus dubia (FD), an indigenous plant of the tropical evergreen rain forest. FD is unique from other Ficus species because of its highly sought-after red-brown latex. Antioxidant properties together with phenolic and flavonoid contents of FD were elucidated. Health-promoting characteristics were examined by studying the inhibition of enzymes as a drug target for diabetes, hypertension, Alzheimer's disease, and obesity, together with anticancer ability against human colorectal adenocarcinoma, human hepatocellular carcinoma, human ovarian carcinoma, human prostate adenocarcinoma, and human lung carcinoma. Besides, FD genotoxicity was tested using the Drosophila wing spot test. Results showed that both FD root and latex exhibited antioxidant activity due to the presence of phenolics and flavonoids, specifically caffeic acid and cyanidin. The ethanolic fraction of FD root demonstrated a potent antidiabetic mechanism underlying α-glucosidase inhibitory activity similar to acarbose. This fraction also suppressed lung and ovarian cancer growth, possibly by G1 and G2/M arrest, respectively. All tested fractions lacked mutagenicity in vivo. Results indicated that FD can be developed as novel antidiabetic compounds; however, its bioactive compounds should be further identified.Obesity has been a well-known risk factor of low-level serum vitamin D. Compared with the traditional obesity-related indicator (body mass index, BMI), associations for two novel anthropometric indices, a body shape index (ABSI) and body roundness index (BRI) with vitamin D deficiency or insufficiency, still remain unclear. This study aimed to assess the associations of serum 25-hydroxy vitamin D (25(OH)D) status with these three obesity-related indices among Chinese adults. A total of 1666 individuals were included. Anthropometric measurements were performed to calculate the indices, and fasting blood was collected to determine serum 25(OH)D deficiency ( less then 12 ng/ml) and insufficiency (12-20 ng/ml). Deficiency or insufficiency of 25(OH)D was found in 37.5% and 43.1% of the participants, respectively. After adjustment for potential confounders, a significantly increased prevalence of 25(OH)D deficiency was observed for higher ABSI (OR Q4 vs Q1 2.334, 95% CI 1.458-3.734; p trend = 0.002) and BRI (OR Q4 vs Q1 2. 215, 95%CI 1.365-3.594; p trend = 0.010), and for higher BMI in men. Regarding 25(OH)D insufficiency, a significant association was also found for ABSI (OR Q4 vs Q1 2.372, 95%CI 1.558-3.612; p trend = 0.001). The area under the ROC of ABSI (0.731, 95%CI 0.687-0.774) for predicting a low level of 25(OH)D was significantly larger than that of BMI (0.695, 95%CI 0.649-0.741) in men, but not in women. A positive association between obesity and lower 25(OH)D serum concentration was found among Chinese adults. Besides BMI, novel obesity-related indicator, ABSI and BRI were associated with lower serum 25(OH)D to some extent, and further studies are needed to clarify their potential to be used as screening tools in clinical practice.Consuming more creatine may be associated with an increased risk of renal dysfunction, yet this link remains poorly addressed at the population level. Using 2017-2018 NHANES data, the current study found that the odds ratio for having failing kidneys in 2,955 U.S adults consuming ≥2.0 g/day of dietary creatine compared to low-intake counterparts ( less then 1.0 g/day) was 0.74 (95% CI from 0.39 to 1.38), indicating no significant association between dietary creatine intake and kidney dysfunction.Aroma is an important factor affecting mushroom character and quality. According to the different reaction pathway, the key aroma metabolites (sulfur and eight-carbon volatiles) formation can be classified into enzymatic reactions and nonenzymatic reactions. Aroma volatiles are generated from precursors via the biocatalytic activities of various synthases during the growth stages of shiitake mushrooms. Understanding the specific relationships between the key aroma metabolites and their synthases is key to improving shiitake mushroom quality. At the same time, to reduce forest logging and burning of agricultural by-products in farmland, agricultural by-products have been applied to shiitake mushroom cultivation. Nevertheless, how to further improve the production of aroma volatiles in mushroom cultivated with agricultural waste is still a challenge. In order to understand the biosynthesis of volatiles via enzymatic reactions and screen the agricultural by-products that can improve the production of aroma volatble.The prevention and management of hypertension are untimely associated with a lowering of sodium intake. The present study aimed to evaluate the sodium and potassium intake levels of Tunisian population through measurement of 24-hr urinary sodium excretions. A randomly, multistage, cross-sectional study was conducted in an urban region (Bizerte) in Tunisia during 2015. The target population involved adults aged from 25 to 64 years. Sodium, potassium, and creatinine concentrations were determined in each urine sample using indirect potentiometric method. From the 420 selected participants, only 194 gave urine samples complying completeness criteria. A multivariate regression model was used to assess the variables related to sodium and potassium excretion. The daily mean excretion of sodium and potassium was 138.3 ± 46.5 mmol/d (corresponding to 8.1 ± 2.7 g/d of salt intake) and 61.0 ± 22.7 mmol/d, respectively. More than 87.1% of the participants (89.8% for men vs. 84.9% for women; p = .31) exceeded the WHO recommendation of 5 g/d.
