| Abstract: | The technology of strawberry yoghurt fermented by Lactobacillus which were immobilized by sodium alginate were studied. Results showed that the optimum technology condition to ferment strawberry yoghurt by immobilized Lactobacillus is 1.5 % sodium alginate concentration, 6 mL skim milk containing strains/100 mL sodium alginate solution, 100 mL sodium alginate solution/100 mL mixture of strawberry and milk, 2 mm～3 mm bead diameter, incubation temperature 40 ℃, 10 % sugar and 15 % strawberry. And the results of continuous fermentation showed that Lactobacillus immobilized by sodium alginate can be used to ferment strawberry yoghurt for 10 times. |
