Intestinal lactic acid bacteria (LAB) for humans are closely associated to the host’s health because the presenceof LAB is an important bio-defense factor in preventing colonization and subsequent proliferation of pathogenic bacteria inthe intestine. Some probiotics such as Lactobacillus species can intoxication of carcinogens including chemical mutagens.The purpose of this study was to compare the ability of antimutagenesity among 24 strains of LAB isolated from infantfeces, yogurt and kimchi etc. The antimutagenic effects of protein fractions extracted from the cells of 24 LAB strains wereinvestigated using mutagens as 4-nitroquinoline-N'-oxide in Ames test (Salmonella Typhimurium TA 100). In the Amestest, dose-dependent activity was exhibited significantly against 4NQO. Three strains of Lactobacillus showed the highestanti-4NQO activitiy (62.1%) among the tested strains of LAB.

This study is a literature review on berries and their cooking methods that appear in ancient and modern Korean literature. Due to recent reports on berries’ excellent functionality and the public’s growing interest in healthy living, berries have been attracted attention as promising forms of sustenance.

Types of berries were classified into six types (Korean cherry, Omija, Gugija, Bokbunja, Black cherry, Mulberry) while cooking methods were classified into five types (Korean traditional snack, Korean traditional beverage, Liquors, Porridge, Pilule) in the ancient and modern literature of Korea. The aim of this literature review is to highlight the valuecreating aspect of berries as food materials that can yield high added-value products. Beyond their value as healthy fruits, this study will explore the features of berries that enhance their added value and brand marketing as well as their aspects suitable for application to the modern industry of berry product development.
