66 person every day. Protein-the main source of essential amino acids-plays the role of building material in the process of cell development and metabolism in the organism. Lack of proteins in the diet can lead to a decrease in the protective properties of the organism, disrupt digestion processes, blood formation, the activity of the central nervous system or weaken mental activity. It is well known that about half 1. Introduction Human nutrition is the main factor in ensuring and improving health. For the proper functioning of the human body, about 600 essential nutrients are needed daily. Proteins-the most important component of the six main components of food should be present in the nutrition of every
This work research object was fat systems interesterification biotechnology using the Lipozyme TL IM immobilized enzyme preparation. The problem of enzyme preparation activation by moistening with sodium bicarbonate aqueous solution with 7.4 ... 7.7 (3 % wt.) pH was solved in the work. The obtained results made it possible to minimize the interesterification process duration with high-quality product obtaining. The proposed enzyme preparation processing made it possible to reduce the duration of the biointeresterification process in a model fat mixture (palm stearin, coconut and soybean oils in a ratio of 1:1:1, respectively) to 3.5...3.7 hours. The product with high quality indicators, namely up to 0.26 mg KOH/g acid number, up to 0.60 mmol ½ O/kg peroxide number and 1.70 c.u. anisidine number, was obtained as a result. The obtained data can be explained by a fact that effective biocatalysis with lipolytic enzymes as the protein molecules requires the existence of two phases – lipid and water. This fact was provided by the activation parameters justified in the study. The obtained results feature was possibility of enzyme preparation activation, which is not provided under industrial conditions due to the threat of raw materials and finished products hydrolytic processes, which leads to the finished product quality deterioration. The research results made it possible to minimize hydrolytic processes in fat system during interesterification with simultaneous process efficiency increase. From a practical point of view, the discovered activation mechanism made it possible to adjust the enzyme preparation processing conditions in fat systems interesterification technology. The applied aspect of scientific result using was the possibility of improving the typical technological process of fat interesterification
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
