Abstract
Tarak is a Korean traditional fermented milk product that is fermented by adding rice wine to milk. Tarak was produced with Lactobacillus paracasei ssp. paracasei M13-65-3 isolated from rice wine, and its effects on immune cell proliferation and melanin biosynthesis were investigated. Tarak extract significantly increased proliferation of T lymphocyte Jurkat clone E6-1 cells at concentrations from 10 to 100 ¥ìg/mL. Tarak inhibited activities of tyrosinase and ¥á-melanocyte-stimulating hormone-induced melanin biosynthesis in mouse skin B16-F10 cells at a concentration of 100 ¥ìg/mL. These results suggest that tarak might have functionalities for enhancing the immune system by increasing immune cell proliferation and regulating melanin biosynthesis.
