Abstract

This study was conducted to identify characteristics of kanjang made with barley bran. Characteristics of kanjang made with barley bran were compared to those of kanjang made with soybean. Total nitrogen was maintained more than 0.7% at 90 days after fermentation. In case of free sugars, the contents of arabinose, xylose, fructose, glucose and maltose were more abundant in kanjang made with barley bran than kanjang made with soybean. The contents of propionic acid and butyric acid were rich among volatile organic acids. Nonvolatile organic acid of lactic acid which was known as abundant component in kanjang was not detected in kanjang made with barley bran. In case of free amino acid, glutamic acid was the most abundant in kanjang made with barley bran, followed by proline and phenylalanine. The ratio of glutamic acid content to total amino acid content was $24.8{\sim}28.0%$. Essential amino acid was $26.7{\sim}29.9%$. Total contents of amino acids were $0.7{\sim}1.4%$. Result of sensory evaluation showed that taste of kanjang made with barley bran was good for fermented after 45 days.
