Hydrolysis of Milk Proteins by Microbial Enzymes

Journal of Food Protection, 1980
Raw skim milk was incubated at 7 C for 15 days after inoculation with six psychrotrophic bacterial cultures previously isolated from raw milk. Effects of the microbial activities on proteins of milk were evaluated by polyacrylamide gel electrophoresis. Results showed that all psychrotrophs hydrolyzed milk proteins.

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

Advanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...
