SURVIVAL IMPROVEMENT OF LACTOBACILLUS ACIDOPHILUS ATCC 4356 IN ANGELICA SINENSIS POLYSACCHARIDE
Khue Cao Huynh Minh, Yen Tran Thi Hai and Tu Nguyen Hoang Khue*
ABSTRACT Lactobacillus acidophilus is a famous probiotic. They provided a lot of health benefits. However, their viability in products is low. Alginate-polysaccharide offers the ability to encapsulate Lactobacillus acidophilus and maintains their survival in capsules. This study evaluated the effect of Angelica sinensis polysaccharide on the growth of Lactobacillus acidophilus ATCC 4356 and the using polysaccharide as coating materials for encapsulation. As a result, bacterial growth increased significantly in medium presented different concentration of polysaccharide (1, 2, 3 mg/ml). However, Angelica sinensis polysaccharide (1 mg/ml) would produce the highest survival in terms of probiotic count approximately 4-6 folds when comparing with traditional medium. Polysaccharide improved the quality of microencapsule surface tense. Within the capsules, the survival rate of bacterium maintained during storage at different temperature from 30oC to 50oC. The study is the first report on the importance of Angelica sinensis polysaccharide in encapsulation and survival rate of Lactobacillus acidophilus that usually dies in a short time even at room temperature. Keywords: Survival, Lactobacillus acidophilus ATCC 4356, Angelica sinensis polysaccharide, Encapsulation. [Download Article] [Download Certifiate] |
