Abstract

|
This study was carried out to investigate changes in nutrient composition and fermentation properties in abalone mul-kimchi using dried pollack stock (AMKP) and licorice stock (AMKL) during storage at 4oC for 35 days. The levels of moisture (88.37-90.94%) and crude ash (2%) did not differ much between AMKP and AMKL during the 35 days of storage. But crude protein and crude lipid levels decreased gradually until 21 days of storage. AMKP and AMKL fermentation during 21 days led to a decrease in pH, increased acidity, and the highest Leuconostoc sp. count. AMKP and AMKL showed acidity of 0.50% at pH 4.30, when the kimchi samples were ripened properly. Glutamic acid showed the highest content in AMKP and AMKL, and hydroxypoline was the most abundant of all free amino acids. We have provided basic data for commodification research on abalone mul-kimchi.
