The macular pigment zeaxanthin, a naturally occurring xanthophyll carotenoid, plays a crucial role in protecting the macula from light-induced oxidative damage; unfortunately, its stability is poor and its bioavailability is low. To enhance both zeaxanthin stability and controlled release, the absorption of this active ingredient into starch granules, as a carrier, can be employed. To achieve high zeaxanthin content (247 mg/g) and high encapsulation efficiency (74%) in the incorporation of zeaxanthin into corn starch granules, a three-factor optimization process was conducted, focusing on the reaction temperature (65°C), starch concentration (6%), and reaction time (2 hours). Utilizing polarized-light microscopy, X-ray diffraction, differential scanning calorimetry, and Fourier transform infrared spectroscopy, the process was found to have partially gelatinized the corn starch. The analyses also demonstrated the presence of corn starch/zeaxanthin composites with the zeaxanthin successfully embedded within the corn starch granules. A noteworthy increase in the half-life of zeaxanthin was observed in corn starch/zeaxanthin composites, reaching 43 days, compared to the 13-day half-life of zeaxanthin alone. The in vitro intestinal digestion of the composites demonstrates a swift elevation in zeaxanthin release, a positive attribute for potential application within living systems. These results suggest promising avenues for crafting starch-based systems for controlled delivery of this bioactive element, incorporating enhanced storage stability and intestinal targeting.
Brassica rapa L., a time-honored biennial herb of the Brassicaceae family, has been extensively employed for its anti-inflammatory, anti-tumor, antioxidant, anti-aging, and immunomodulatory properties. In vitro investigations were undertaken to assess the antioxidant activity and protective effects against H2O2-induced oxidative stress in PC12 cells, employing active fractions derived from BR. In the evaluation of all active fractions, the ethyl acetate fraction of the ethanol extract from BR (BREE-Ea) possessed the strongest antioxidant capability. Subsequently, it became evident that both BREE-Ea and the n-butyl alcohol fraction of the ethanol extract from BR (BREE-Ba) exhibited protective effects on PC12 cells subjected to oxidative stress, with BREE-Ea showcasing the strongest protective influence in all of the experimental doses assessed. supporting medium Flow cytometric analysis (DCFH-DA staining) revealed that BREE-Ea administration to PC12 cells challenged with H2O2 decreased the incidence of apoptosis. This effect correlated with a reduction in intracellular reactive oxygen species (ROS) production and an increase in the enzymatic 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. Evidently, BREE-Ea exhibits noteworthy antioxidant capacity and protective effects on PC12 cells subjected to H2O2-induced apoptosis, thus establishing it as a promising edible antioxidant that improves the body's inherent antioxidant defenses.
Lipid production utilizing lignocellulosic biomass has seen a noticeable rise in interest, particularly given the recent shift away from food sources used in biofuel production. The struggle for raw materials, needed in both sectors, requires the development of technological alternatives to lessen this competition, potentially diminishing the food supply and thus leading to a corresponding increase in the price of food in the market. In addition, the utilization of microbial oils has been explored within numerous branches of industry, spanning from the generation of renewable energy sources to the extraction of valuable byproducts in the pharmaceutical and food processing sectors. This review, therefore, offers a comprehensive perspective on the practicality and obstacles encountered during microbial lipid production using lignocellulosic biomass within a biorefinery setting. 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.
Dairy industry by-products hold a high volume of bioactive compounds, which potentially carry added economic value. This study investigated the antioxidant and antigenotoxic properties of milk-derived components, including whey, buttermilk, and lactoferrin, using two human cell lines: Caco-2, representing the intestinal barrier, and HepG2, representing hepatic cells. We scrutinized the protective influence of dairy samples in countering oxidative stress, originating from menadione. The dairy fractions' antioxidant effects were striking, with the non-washed buttermilk fraction having the largest positive impact on Caco-2 cell oxidative stress and lactoferrin demonstrating the most powerful antioxidant action for 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 maintained their functional characteristics in a coculture environment with Caco-2 and HepG2 cells, mimicking the interactions of the intestinal and liver systems. This outcome suggests that compounds responsible for the antioxidant effect are capable of crossing the Caco-2 barrier and reaching HepG2 cells on their basal side, thus fulfilling their antioxidant potential. Finally, our findings demonstrate that dairy by-products possess antioxidant and antigenotoxic properties, thereby warranting a reconsideration of their application in culinary creations.

To assess the impact of yam bean powder (YBP) additions (0-125%), this study investigated the resulting changes in the structure, water-holding capacity, chemical interactions, and textural attributes of grass carp myofibrillar protein (MP) gels. The YBP's results highlighted its robust water absorption, permeating the heat-induced protein gel structure. This allowed for efficient water entrapment within the network, ultimately producing MP gels with noteworthy water-holding capacity and substantial gel strength (075%). Furthermore, YBP prompted the creation of hydrogen and disulfide bonds within proteins, while also hindering the transformation of alpha-helices into beta-sheets and beta-turns, thus aiding in the development of robust gel networks (p < 0.05). In essence, YBP's presence substantially augments the thermal gel-forming capabilities of grass carp muscle protein. Importantly, incorporating 0.75% YBP into the grass carp MP gel system exhibited the most pronounced effect in creating a continuous and dense protein network, resulting in a composite gel with outstanding water-holding capacity and superior texture.
Protection is achieved through the use of nets in bell pepper packaging. In spite of that, the manufacturing procedure is predicated on polymers that are detrimental to the environment. To study the impact of biodegradable nets, like poly(lactic) acid (PLA), poly(butylene adipate-co-terephthalate) (PBAT), and cactus stem byproducts, on four varieties of 'California Wonder' bell peppers, a 25-day storage period was implemented under controlled and ambient temperature conditions. When compared, bell peppers in biodegradable nets demonstrated no significant variation from those in commercial polyethylene nets regarding color, weight loss, total soluble solids, and titratable acidity. A statistically significant (p < 0.005) disparity was found in the levels of phenol content, carotenoids (orange bell peppers), anthocyanins, and vitamin C, with samples packaged in PLA 60%/PBTA 40%/cactus stem flour 3% demonstrating a higher overall content when contrasted against samples in commercial packaging. 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. This net, a postharvest packaging option for bell peppers, presents a viable solution for their storage.
