Efficient conversion of conjugated linoleic acid c9,t11 by Lactobacillus fermentation from vegetable oil to generate fermented milk with high CLA content KCI 등재 SCOPUS
pp.482-489
The purpose of this study was to develop a functional and valuable dairy product with high conjugated linoleic acid (CLA) content through a fermentation method utilizing vegetable oil and probiotic lactic acid bacteria. Bifidobacterium breve KCTC 3419 was selected as a standard strain for high efficiency conversion of the CLA c9,t11. This standard strain was mixed in a definite ratio of 4:3:3 with Lactobacillus sakei LJ011 isolated from kimchi and the commercially available YF-L812 culture to generate a high-efficiency CLA conversion starter stock for use in fermented milk production. CLA conversion by safflower seed oil fermentation by the starter stock yielded the highest CLA containing fermented milk. The pH level, titratable acidity, and number of lactic acid bacteria in the fermented milk were altered to suitable levels during the fermented milk production process. The CLA content of CLA-fermented milk was maintained at 0.1% of the total CLA content during the storage period of 2 weeks.
