INTENSIFICATION OF THE MELANOIDIN FORMATION REACTION IN THE PRODUCTION OF SWEET BOILED CANNED MILK

Abstract

The article gives empirical grounding of reducing the melanoidins formation process duration at high-temperature processing of sweet canned milk due to the use of enzymatic hydrolysis of lactose. In sweet canned milk samples with hydrolyzed lactose there was a more intensive decrease in active acidity and an increase in oxidation-reduction potential and obviously a change in milk color within a short period of time by contrast to milk with not hydrolyzed lactose. Lactose disaccharide splitting to (38±2)% allows to reduce the duration of high-temperature processing average by 40% at traditionally applied prossing temperature of (105±5) °C, and reduce the sucrose content in the finished product by 3–8%. The use of fructose in order to accelerate the process of cooking whole condensed milk is not rational.
