Zeaxanthin, a natural xanthophyll carotenoid, serves as the principal macular pigment, safeguarding the macula from light-initiated oxidative damage, but its inherent instability and low bioavailability represent a key limitation. Absorption of this active ingredient, utilizing starch granules as a carrier, results in improved stability and a controlled release of zeaxanthin. The incorporation of zeaxanthin into corn starch granules was optimized using three key variables: a reaction temperature of 65°C, a 6% starch concentration, and a 2-hour reaction time. This optimization was performed with the expectation of achieving high zeaxanthin content (247 mg/g) and high encapsulation efficiency (74%). Corn starch gelatinization, a partial outcome of the process, was confirmed through analyses using polarized-light microscopy, X-ray diffraction, differential scanning calorimetry, and Fourier transform infrared spectroscopy. Subsequently, the presence of corn starch/zeaxanthin composites was evident, with the zeaxanthin effectively incorporated within the structure of the corn starch granules. The half-life of zeaxanthin in corn starch/zeaxanthin composites was significantly increased to 43 days, as contrasted with the initial 13-day half-life of zeaxanthin alone. Zeaxanthin release from the composites accelerates significantly during in vitro intestinal digestion, indicating suitability for use in biological systems. Applications for these findings include the development of enhanced starch-based carriers for this bioactive agent, featuring extended stability and targeted intestinal release.
Recognized for its diverse medicinal properties, Brassica rapa L. (BR), a traditional biennial herb within the Brassicaceae family, has been widely used for its anti-inflammatory, anti-tumor, antioxidant, anti-aging, and immunomodulating actions. In vitro, the active components of BR were examined for their antioxidant and protective capabilities in mitigating H2O2-induced oxidative damage within PC12 cells. The BR (BREE-Ea) ethanol extract's ethyl acetate fraction showed a more potent antioxidant activity than any other active fraction. It was also noted that BREE-Ea and the n-butyl alcohol fraction of the ethanol extract from BR (BREE-Ba) demonstrated protective capabilities in oxidatively damaged PC12 cells, BREE-Ea proving to be the most effective protector across the diverse doses tested. CVT-313 order BREE-Ea, as indicated by flow cytometry (DCFH-DA staining), was found to lessen H2O2-induced apoptosis in PC12 cells. This was accomplished by decreasing intracellular reactive oxygen species (ROS) and enhancing the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Additionally, BREE-Ea potentially decreased malondialdehyde (MDA) content and reduced the leakage of extracellular lactic dehydrogenase (LDH) from H2O2-exposed PC12 cells. The antioxidant properties and protective actions of BREE-Ea on PC12 cells, as demonstrated by these results, highlight its potential as a valuable edible antioxidant, enhancing the body's natural antioxidant mechanisms in response to H2O2-induced apoptosis.
Lipids derived from lignocellulosic biomass are gaining prominence as an alternative, especially in light of the increasing scrutiny surrounding food-based biofuel production. Competition for raw materials used in both applications necessitates the development of alternative technologies to alleviate this competition, which could lead to reduced food production and an increase in the cost of food in the marketplace. Consequently, the use of microbial oils has been examined within a diverse range of industrial practices, from sustainable energy creation to the development of high-value products within the pharmaceutical and food industries. Subsequently, this examination provides an overview of the practicality and challenges associated with the production of microbial lipids using lignocellulosic feedstocks in a biorefinery system. The subjects under discussion include biorefining technology, the microbial oil market, oily microorganisms, the mechanisms behind lipid production in microorganisms, strain engineering, the associated procedures, lignocellulosic lipid sources, technological difficulties, and strategies for lipid recovery.
A considerable amount of bioactive compounds, present in the by-products generated by the dairy industry, could potentially bring added value. The objective of this research was to assess the antioxidant and antigenotoxic activities of milk-derived compounds—whey, buttermilk, and lactoferrin—in two human cellular models, Caco-2 (intestinal barrier) and HepG2 (hepatic cell line). An analysis was conducted to assess the protective effect of dairy samples against oxidative stress induced by menadione. Oxidative stress was substantially reversed by all of these dairy components, the non-washed buttermilk fraction having the greatest antioxidant impact on Caco-2 cells and lactoferrin exhibiting the strongest antioxidant activity in HepG2 cells. At concentrations that did not affect cell viability, the dairy sample exhibiting the greatest antigenotoxic potency against menadione, across both cell lines, was lactoferrin at the lowest dosage. Dairy by-products, in consequence, retained their activity within a co-culture of Caco-2 and HepG2 cells, faithfully reproducing the intricate workings of the intestinal-liver axis. The antioxidant compounds' capacity to traverse the Caco-2 barrier and engage HepG2 cells on the basal side, enabling their antioxidant activity, is implied by this result. In conclusion, our study's results reveal antioxidant and antigenotoxic activities in dairy by-products, which could lead to a re-evaluation of their application in specialized food products.
This study explores the effect of deer and wild boar game meats on the quality characteristics and attributes affecting the mouthfeel of skinless sausage. A comparison between grilled game meat cevap and standard pork meat specimens formed the basis of this investigation.

Analysis of oral processing attributes across the samples demonstrates a striking similarity, corroborating the outcomes of the pork-based sample investigation. We have a confirmation of the working hypothesis that game-meat based cevap is on par with the quality of conventionally made pork products. medicated serum The sample's game meat variety has a reciprocal effect on the coloration and taste profile. The primary sensory characteristics experienced during the act of chewing were the flavors of game meat and its juiciness.
The study examined the impact of yam bean powder (YBP) concentrations ranging from 0% to 125% on the structural integrity, water-holding capacity, chemical bonding, and textural properties of grass carp myofibrillar protein (MP) gels. The YBP's performance demonstrated a considerable capacity for water absorption, effectively filling the protein-based heat-induced gel structure. This enabled the gel network to successfully capture and retain water, ultimately producing MP gels exhibiting high water holding capacity and substantial gel strength (075%). YBP, in addition, catalyzed the formation of hydrogen and disulfide bonds in proteins, and it impeded the conversion of alpha-helices into beta-sheets and beta-turns, leading to the formation of strong gel networks (p < 0.05). In closing, YBP significantly impacts the thermally induced gelling capabilities of grass carp muscle protein. The 0.75% YBP addition significantly contributed to the filling of the grass carp MP gel network, producing a continuous and dense protein network, thereby optimizing the water-holding capacity and texture of the composite gel.
Bell pepper packaging employs nets as a safeguard. Nonetheless, the manufacturing process is built upon polymers that generate severe environmental repercussions. A 25-day storage experiment under controlled and ambient temperatures assessed the impact of nets crafted from biodegradable materials like poly(lactic) acid (PLA), poly(butylene adipate-co-terephthalate) (PBAT), and cactus stem residue on four different hues of 'California Wonder' bell peppers. Biodegradable nets, unlike commercial polyethylene nets, exhibited no discernible variation in bell pepper color, weight loss, total soluble solids, or titratable acidity. A pattern emerged where samples utilizing PLA 60%/PBTA 40%/cactus stem flour 3% packaging showed a higher concentration of phenol content, carotenoids (orange bell peppers), anthocyanins, and vitamin C compared to those using commercial packaging, with statistically significant differences (p < 0.005) observed across the measured parameters. In conjunction with these findings, this same network considerably limited the growth of bacteria, fungi, and yeasts during the storage of red, orange, and yellow bell peppers. For storing bell peppers post-harvest, this net is a potentially suitable packaging choice.
