Changes in Pectic Substances of Korean Pickled Cucumbers with Different Preparation Methods

담금 방법을 달리한 오이지의 숙성 중 펙틴질의 변화

Abstract

This investigation was undertaken for the purpose of studying the changes of pectic substances in alcohol insoluble solids(AIS) extracted from cucumbers pickled in salt. The preparation methods were brining the cucumbers in 10% NaCl solution (bolied, method A), 20% NaCl solution(bolied, method B) and 20% NaCl solution(cool to $25^{\circ}C$ after boiling, method C). The composition ratio of hot water soluble pectin(HWSP) in AIS decreased during brining, while that of 0.4% sodium hexametaphosphate soluble pectin(NaSP) increased remarkably. The contents of Ca and Mg in AIS increased regardless of preparation methods used. By DEAE-cellulose chromatography, HWSP from fresh and brined cucumbers were divided into six fracitons. 0.2M peak was the main fraction in fresh cucumber, whereas 0.05M and 0.2M peak were the main fraction in pickled cucumbers. On the other hands, NaSP from fresh and brined cucumbers were divided into five fractions and 0.4M peak was the main fraction. However, the composition ratios of galacturonic acid and neutral sugar of 0.4M fraction in brined cucumbers were higher than those of fresh cucumber.
