Abstract:
The objective of the article boils down to evaluate raw milk quality obtained under conditions of intensive robotic and baromembrane technologies for increasing microbiological stability. The article presents the analysis of phys icochemical, biotechnological and microbiological parameters of raw milk produced using the Lely Astronaut A4 ro botic milking system in comparison with milking into a milk pipeline using the DA-2M "Maiga" apparatus, subjected to baromembrane "cold" sterilization on CMFE microfiltration membranes. It has been established that the use of intensive robotic technologies - the Lely Astronaut A4 robotic milking system - allows to increase milk yield by an average of 12% compared to milking into a milk pipeline, reduce bacterial contamination of milk to less than 500 thousand bacteria in 1 ml and reduce titratable acidity by 0.17 °T. The authors have shown that optimal microbiologi cal parameters of milk are achieved by the microfiltration method. It has been established that during microfiltration sterilization of pre-skimmed milk on CMFE membranes, 99.9% of spores and bacteria are removed. To normalize the fat content of milk after baromembrane "cold" sterilization, the required amount of cream, sterilized by the classical thermal method with subsequent homogenization, is added.
