Summary

A FREEZE-DRIED STARTER WAS DEVELOPED FROM THE MICRO-ORGANISMS FOUND IN KEFIR GRAINS, FOR USE ASA BULK STARTER INOCULUM. THESE WERE SELECTIVE STRAINS OF APPROXIMATELY 75% HOMOFERMENTATIVE LACTIC STREPTOCOCCI, 24% CITRIC ACID FERMENTING STREPTOCOCCI, 0.5% LACTOBACILLI AND 0.1% YEASTS (CANDIDA KEFIR). THE SURVIVAL RATE OFTHE YEASTS AFTER FREEZE-DRYING WAS 40-50% AND FOR THE REMAINDER 20-70%. THE STARTER WAS COMPARED WITH CONVENTIONAL GRAINS AS A MOTHER STARTER ; THE MICROBIOLOGICAL COMPOSITION OF THE FORMER BEING MORE UNIFORM. KEFIR PRODUCED FROM THE FREEZE-DRIED STARTER WAS OF MORE UNIFORM QUALITY AND THE LEVEL OF THE MICRO-ORGANISMS WAS LESS VARIABLE. THE YEAST TASTE IN THE KEFIR WAS LESS DOMINANT, THIS BEING CONFIRMED BY ORGANOLEPTIC TESTS. G.R.S.
