Abstract

Milk has a great importance and nutritional value in human nutrition and it is therefore of great importance to ensure the milk microbiological safety. However, milk also represents a problem for people with allergies to their constituents, such as the caseins, a-lactalbumin and b-lactoglobulins. Lactic acid bacteria have been used by mankind for a long time due to their technological potential and ability to improve sensorial attributes of foods. The biopreservative potential of lactic acid bacteria is due to the production of organic acids, hydrogen peroxide and bacteriocins. Furthermore, lactic acid bacteria are important for the ability of modify milk proteins during fermentation, which can generate peptides with different biological activities and better digestibility by people with allergies. This project aims to evaluate the activity of lactic acid bacteria, isolated from milk and cheese, on the allergenic properties of whey proteins. The peptides derived from the activity of lactic acid bacteria on whey will be characterized with regard to antimicrobial activity and allergenicity with in vitro tests. (AU)
