Despite identical dosages, GEKE exhibited a more pronounced improvement in hyperglycemia, abnormal lipid profiles, and renal tissue damage (as verified by histological examination) in diabetic mice compared to EKE. Following treatment protocols, diabetic mice displayed decreased levels of kidney microalbuminuria (ALB), blood urea nitrogen (BUN), serum creatinine (Scr), malondialdehyde (MDA), and glutathione (GSH), and conversely, elevated levels of catalase (CAT), superoxide dismutase (SOD), and serum total antioxidant capacity (T-AOC). EKE and GEKE treatments display the ability to ameliorate both diabetes and kidney ailments by addressing hyperglycemia, oxidative stress, and kidney function markers, as well as by modulating the Keap1/Nrf2/HO-1 and AMPK/mTOR signaling cascades. However, GEKE proves more potent in each of these two approaches. A key objective of this study was to investigate the consequences of GEKE and EKE treatments on the antioxidant defense and metabolic capabilities of diabetic animals. Implementing germination techniques represents a viable strategy for amplifying the medicinal benefits inherent in these plant-based preparations.
Consumers today show an elevated concern for meat products containing solely safe and natural additives. Subsequently, the critical need to employ natural food additives for prolonging the storage life of meat and hindering microbial development has become paramount. Given the rising acceptance of Moringa oleifera leaves as a traditional treatment, and the paucity of published information on their antimicrobial activity against foodborne pathogens in meat and meat products, the current study investigated the antimicrobial effect of Moringa oleifera leaf aqueous extract (0.5%, 1%, and 2%) on ground beef stored at 4°C for 18 days. Ceftaroline MLE demonstrated substantial antimicrobial activity against spoilage bacteria, exemplified by the aerobic plate count and Enterobacteriaceae. Following 18 days of storage, ground beef treated with MLE 2% showed a statistically significant (p < 0.001) decrease in the numbers of E. coli O157:H7, Salmonella enterica serovar Typhimurium, and Staphylococcus aureus artificially inoculated at 654, 535, and 540 log10 CFU/g, respectively, compared to untreated controls. Ground beef samples treated with Moringa leaves extract (MLE) experienced no negative effects on general acceptability and sensory attributes; rather, treated samples showed a modest improvement in tenderness and juiciness in contrast to the control. Thus, Maximum Likelihood Estimation (MLE) acts as a healthy, natural, and safe preservative, augmenting the safety, quality, and shelf life of meat products kept under cold conditions. A revolutionary shift in the food industry could emerge from the application of natural food additives as a safer replacement for chemical preservatives, eliminating potential health risks for consumers.
Scientific findings indicate that polyphenols are capable of potentially increasing the time span during which fish products retain their quality. The present study explored the effects of phenolic extracts from grape seeds (GSE), lotus seedpods (LSPC), and lotus roots (LRPE) on refrigerated channel catfish fillets, specifically examining changes in physicochemical properties and bacterial communities during storage at 4°C, contrasting their efficacy with ascorbic acid (AA). The introduction of GSE, LSPC, LRPE, and AA reduces the rate at which microbes reproduce in catfish fillets during storage. The microbial community study demonstrated that adding polyphenols led to a marked reduction in the relative abundance of Proteobacteria in the initial phase of storage, along with a change in the community's distribution in the later stages. Following 11 days of storage, a substantial decrease in total volatile base nitrogen (TVB-N) was observed in the fish samples of the GSE, LSPC, LRPE, and AA groups, reducing by 2585%, 2570%, 2241%, and 3931%, respectively, compared to the control group (CK). Ceftaroline Subsequently, sample lipid oxidation was mitigated, resulting in a 2877% decrease in thiobarbituric acid-reactive substances (TBARS) within the GSE group relative to the CK group. Ceftaroline Centrifugal loss, LF-NMR, and MRI findings clearly established GSE's significant impact on delaying the loss of water and the increase in the flow rate of immobilized water in catfish filets. Polyphenol treatment of the samples yielded a lessened decrease in shear force and muscle fiber damage, a difference observed histologically when compared to the CK group. Subsequently, freshwater fish quality and shelf life can be enhanced by developing the natural antioxidant properties of dietary polyphenols, including GSE, LSPC, and LRPE.
An investigation into the presence of select trace elements (arsenic, mercury, cadmium, and lead) was conducted on the muscle tissues of the common meagre (Mullus barbatus) and the European hake (Merluccius merluccius) to establish the daily intake of these elements through fish consumption and evaluate associated human health risks. Across the entire study period, the average arsenic concentrations in the muscle tissue of M. barbatus and M. merluccius were 19689 mg/kg wet weight (ww) and 8356 mg/kg ww, respectively, while mercury levels were 0497 mg/kg ww and 0153 mg/kg ww, and lead levels were 0031 mg/kg ww and 0025 mg/kg ww, respectively. Cadmium (Cd) concentrations within every fish sample fell below the limit of detection, which was set at less than 0.002 milligrams per kilogram of wet weight. Potential health risks were evaluated using target hazard quotients (THQ) and estimated daily intakes (EDI). The results indicated a substantial risk of arsenic (As) exposure in both fish species and mercury (Hg) in *M. barbatus*. The calculated hazard index (HI) for both fish species surpassed the value of 1. The sustained monitoring of trace element levels in fish is highly recommended, as the data indicates a possible threat to health because of arsenic and mercury contamination.
With bioactive and functional attributes, mushroom by-products are an economical and eco-friendly option for food ingredient development. Even though mushroom upcycling offers many potential applications, full exploitation remains elusive despite the abundance of possibilities. A comprehensive analysis of the mushroom protein by-product (MPBP), including its chemical composition, physicochemical properties, and functional characteristics, was carried out following its derivation from mushroom protein production. This MPBP was subsequently incorporated into the creation of plant-based batter formulations for four separate experimental groups with varying weight ratios of wheat flour (W) to MPBP (100 W, 75 W/25 MPBP, 25 W/75 MPBP, and 100 MPBP). The batter was used to coat shrimp that were subsequently deep-fried. The resulting products were assessed with regards to their cooking loss, coating adherence, oil uptake, and color characteristics based on L*, a*, and b* color space. MPBP's substantial dietary fiber content, primarily insoluble fiber (49%), positions it as a promising candidate for the creation of high-fiber food products. The MPBP's physicochemical characteristics, including pH (1169), water activity (0.034), L* (5856), a* (561), b* (1803), and a particle size distribution (250-500 µm (2.212%), 125-250 µm (4.118%), 63-125 µm (3.753%), and less than 63 µm (0.82%)) were documented. Functional characteristics of MPBP included solubility of 127%, an emulsifying activity index of 76 m²/g, an emulsion stability index of 524 minutes, a water-holding capacity of 49%, and an oil-holding capacity of 48%. Utilizing MPBP in batter recipes for shrimp resulted in higher cooking losses, oil absorption, coating pick-up, and a* color, but correspondingly lower L* and b* color values. The experimental data obtained from the 75 W/25 MPBP group showcased superior results, indicating the potential of MPBP as a novel batter ingredient to partially substitute wheat flour.
Using gas-liquid chromatography, we analyzed the fatty acid profile of the muscles from northern pike (Esox lucius Linnaeus, 1758) found in the Gyda River, Siberia, Russia. Among the 43 fatty acids present in the pike samples, 23 fatty acids collectively made up 993% of the total. Palmitic (C16:0) acid, at 200%, and stearic (C18:0) acid, accounting for 73%, were the most prevalent saturated fatty acids (SFAs), amounting to a total of 316%. Among monounsaturated fatty acids (MUFA), oleic acid (C181n9) and palmitoleic acid (C161) showed the greatest abundance, with percentages of 102% and 41% respectively, from the total monounsaturated fatty acids, which amounts to 151%. Arachidonic acid (C20:4n-6, 76%), eicosapentaenoic acid (EPA, C20:5n-3, 73%), and docosahexaenoic acid (DHA, C22:6n-3, 263%) were found to be the most common polyunsaturated fatty acids (PUFAs), contributing significantly to the overall total. The fatty acid makeup of Gyda River pike differed significantly from that of other pike populations, most probably due to dietary disparities. Pike flesh's nutritional value is highlighted by its low n-6/n-3 ratio (0.36), low atherogenic (0.39) and thrombogenic (0.22) characteristics, and its high proportion of hypocholesterolemic fatty acids relative to hypercholesterolemic ones (283). This makes it an excellent substitute or alternative to conventional fish choices in standard diets.
A study was conducted to investigate the changes in bitterness of salmon frame protein hydrolysate (SFPH) and salmon frame protein plastein (SFPP) following liposomal encapsulation using ultrasound (20% amplitude, 750 W) for time intervals of 30, 60, and 120 seconds. Liposomes encapsulating 1% protein hydrolysate (L-PH1) and 1% plastein (L-PT1) achieved the most efficient encapsulation and the least bitterness, a statistically significant finding (p < 0.05). The negative impact of prolonged ultrasonication on encapsulation efficiency (EE) for L-PH1 and L-PT1 manifested as increased bitterness and a smaller particle size. A difference in bitterness was observed when comparing L-PH1 and L-PT1, with L-PT1 exhibiting a lower bitterness profile due to a naturally lower bitterness and a higher capacity for plastein inclusion within the liposomes. In vitro release studies of peptides from L-PT1 demonstrated a delayed release characteristic when compared to the control plastein hydrolysate. In light of this, encapsulating liposomes with 1% plastein could constitute an effective approach to enhancing the sensory perception of protein hydrolysates, thereby reducing their bitterness.
