Summary: This study evaluated the susceptibility of whey proteins to enzyme hydrolysis and the antidiabetic properties of protein hydrolysates. The results showed that alpha-LA hydrolysate was more effective than beta-LG hydrolysate in inhibiting DPP-W activity and increasing GLP-1 levels. Heat treatment at 75 degrees C had the greatest impact on the antidiabetic properties of the protein hydrolysates.

Summary: In this study, high-pressure processing was used to remove beta-Lactoglobulin from bovine native whey concentrate and generate an enriched alpha-Lactalbumin fraction. The optimal conditions for alpha-Lactalbumin yield and purification degree were determined. The results showed that high-pressure processing could improve the precipitation of beta-Lactoglobulin and the purification of alpha-Lactalbumin. Further characterization and application of membrane concentration and high-pressure processing are recommended for the valorization of cheese whey.

Summary: The study aimed to measure whey protein removal from sweet whey using polymeric microfiltration membranes and compared the performance with ceramic membranes. Results showed that polymeric membranes achieved lower yield of whey protein isolate and higher yield of whey protein phospholipid concentrate compared to ceramic membranes, impacting total gross revenue and the ratio of market price between the two products. Economic engineering study is needed to determine the long-term processing costs and net revenue under various market conditions.

Summary: The experiment used a top-down method to quickly and efficiently screen strains with low allergenic potential and prepared fermented milk. Through direct screening of traditional fermented dairy products from Xinjiang, the BZ-21 sample with the lowest antigenicity was selected and 13 strains were isolated from it. These strains were safe and the fermented milk prepared under optimized fermentation conditions showed reduced antigenicity and IgE-binding capacity. The top-down screening method used in this experiment was effective and these 13 strains will be potential probiotics in the development of low-allergenic dairy products.

Summary: The study aimed to measure the removal of whey protein using 0.1-micron ceramic microfiltration membranes at 50 degrees Celsius. Results showed that most total nitrogen passed through the membrane into the permeate, lactoferrin did not pass through, while other components such as IgG, bovine serum albumen, glycomacropeptide, and casein proteolysis products did pass into the permeate.

Summary: Whey from goat and sheep are being studied for their nutritional properties, but the presence of beta-Lg in these whey sources may cause allergies in infants. Therefore, researchers are interested in developing whey ingredients with higher alpha-La/beta-Lg ratios. This study investigated the effect of high-pressure processing on goat and sheep native whey concentrates (NWC) to obtain alpha-La-enriched fractions. The results showed that high-pressure processing reduced the concentration of beta-Lg in NWC, while alpha-La concentration remained unchanged.

Summary: An increasing number of cheese-making companies are using high-protein milks to increase cheese yield. This study explored the impact of reducing whey protein (WP) levels in concentrated cheese milk on cheese characteristics. The results showed that reducing WP levels did not affect the pH, sensory attributes, or insoluble calcium content of cheese, but it did lower the protein hydrolysis and hardness and melting point of the cheese.

Summary: This study investigated the use of Aqueous Two-Phase Systems (ATPS) for the recovery of lactose, BSA, beta-lactoglobulin and alpha-lactalbumin from cheese whey. Different ATPS were studied for partitioning the selected solutes, showing efficient recovery of proteins and lactose under optimized conditions. This polymer/salt ATPS method could be a scalable and cost-effective separation strategy for cheese whey and related wastes.

Summary: Whey protein components have anticancer attributes and can reduce the risk of colorectal cancer. They have anti-inflammatory and antioxidant abilities and can induce apoptosis, inhibit tumor cell proliferation, and impede metastasis. Studies have shown the importance of incorporating whey protein components into a balanced daily diet for the prevention and treatment of colorectal cancer.

Summary: This review provides an overview of the beneficial effects of whey protein (WP) and its components on human health, particularly in controlling obesity and its comorbidities. WP consumption positively impacts energy balance and obesity-related parameters, primarily through modulation in adipose tissue metabolism and changes that occur in the gastrointestinal tract. Furthermore, WP also has a positive impact on gut microbiota, mood, and behavior. This review emphasizes the importance of WP supplementation in preventing or treating obesity and highlights areas for further research.

Summary: Whey protein, an important source of nutrition and biotechnology, is considered a by-product of the dairy industry due to low economic value. The challenge in whey protein separation lies in low concentration and similar properties. Ion exchange techniques are widely used for separation, and recent research on ion exchange membranes shows promise for industrial application. Adsorption-based methodologies targeting protein structure differences are anticipated to further improve whey protein separation.

Summary: The properties of chitosan films are significantly affected by the type of acid and glutaraldehyde crosslinking, which reduces the swelling degree and increases fragility of the films. Crosslinking does not completely prevent the biodegradation of the films but requires a longer time. Ecotoxicity analysis suggests that the films can be composted.

Summary: The development of starch-based films has shown the potential for creating transparent, non-toxic, biodegradable materials with good gas barrier properties. However, the use of starch in packaging should be avoided due to world hunger-related problems. Utilizing residual starches can reduce production costs and promote the development of innovative biomaterials. The addition of gelatinized starch from agro-industrial residues in bioplastic production has shown a decrease in tensile strength and elastic modulus values, but no significant impact on elongation percentage values.
