Abstract

Changes in quality of blanched vegetables(carrot, green onion, spinach) by microwave heating were evaluated. Ceramic coating treatment(CCT) within microwave oven caused the reduction of blanching time and Hunter's L, a, b values of vegetables. Also, CCT showed the higher cutting force compared to NCCT after microwave heating. Photomicrographs of cross-section of blanched vegetables after heating in ceramic coated microwave oven showed better appearance than those in nonceramic coated microwave oven. CCT process improved retention of vitamin C.

당근, 쪽파, 시금치와 같은 채소류에 대한 데치기 실험에서 데치기 시간은 전자레인지 CCT가 빨랐으며, 색도 및 절단강도 변화에서는 데치기 처리로 명암도, 적녹도, 황청도, 절단 강도가 대조구에 비하여 감소하였으며 그 감소 폭은 전자레인지 CCT의 경우가 적었다. 미세구조 관찰에서는 전자레인지 CCT가 NCCT보다 조직 구조가 덜 파괴하는 것으로 나타났으며, vitamin C 함량에서도 전자레인지 CCT가 손실이 적었다.
