Abstract

Abstract:

A yogurt with c9, t11-conjugated linoleic acid (CLA) was prepared by adding suitable substrate and nutrients to milk for Lactobacillus fermentation. Milk fat was extracted and CLA was quantitatively determined by gas chromatography to design the administration dosage and study the immunoregulatory function of CLA in mice. Results indicated that the administration of CLA at a dose of 0.05 g/kg bw·d for 30 consecutive days could significantly enhance immunoregulatory function in mice. This fact demonstrates an excellent immunoregulatory effect of CLA in mice.

Key words: Lactobacillus fermentation, c9, t11-conjugated linoleic acid (CLA), milk fat, immunoregulation
