Research Abstract

In the present study, we performed to evaluate the production CLA in cream from pasture fed cow milk by several lactic acid bacteria starters and the effect on flavor formation of the product.
The CLA level in non-homogenized cream from pasture-fed cow milk, which had been cultured with Gouda cheese starter for 6 hr, was significantly higher than that in pre-cultured cream. The concentration of CLA in the homogenized cream, which had been cultured with Lactobacillus helveticus strain, was higher than that in the pre-cultured cream. However, these levels in both homogenized and non-homogenized cream, which were cultured with probiotic lactic acid bacterial strains, were lower than those in the pre-cultured cream. In conclusion, it is suggested that the CLA level in the cream from pasture-fed cow milk may increase by homogenizing or culturing with lactic acid bacterial strains.
