Development of Bovine Milk with reduced allergenity
Cow’s milk protein allergy (CMPA) affects from 2 to 6 % of children, with the highest prevalence during the first year of age. The allergenic or antigenic nature of a protein is influenced by its primary structure (amino acid sequence and attached carbohydrates) and its molecular conformation. Consequently, modifying either the primary structure or the protein’s conformation can lead to a reduction in allergenicity or antigenicity. Enzymatic hydrolysis is viewed as the optimal approach to diminish the allergenic reactivity of CMPs. The manipulation of milk protein hydrolysis can be regulated through the choice of specific enzymes, operating conditions, and parameters.
Recovery by membrane filtration and reuse of drainage
Drainage waters are an overlooked and cheap sourse for dissolved ions, among them phophorus and nitrogen which are essential for cultivation. Within the frames of the project ecomonical technology is developed in order to separate natural sludges from their water content, pretreat the drainage and it's advanced concentration by two-step membrane filtration which enables the reduction of some monovalent salt ion in paralel.
