摘要：Investigations were carried out in order to find out the process of production of fructose enriched yoghurt which is intended for people whose working activity is characterised by long and persistent intellectual and (or) physical efforts. Mixtures of milk with more than 10 % fructose fermented very slowly with yoghurt cultures. Best results were obtained by acidifying evaporated skim milk with 5 % yoghurt cultures to which a concentrated solution of fructose containing 0,5 % of stabiliser (Cremodan) was added. Both, acidified evaporated skim vnilk and fructose syrup, were brought to 5 °C before thorough mixing, in order to prevent serum separation. The product was refreshing and pleasant for consumption. It contained in average 40,9 % TS, 24 % fructose. Physical characteristics were: specific density 1,162, viscosity 184 cP and pH 5,1 (titrable acidity 144 °T).
