토마토소스 및 토마토페이스트소스 첨가 구운굴(Crassostrea gigas)통조림의 제조 및 품질특성

Abstract

This study collected basic data on two types of canned roasted oyster Crassostrea gigas. Oysters Crassostrea gigas were immersed at 105℃ for 6 min and then washed and dehydrated before pre-drying. Roasted oysters were prepared by baking boiled oysters at 140℃ for 20 min. The canned roasted oyster added with tomato sauce was prepared as follows. An aluminum can was filled with 50 g of roasted oyster and 40 g of mixed seasoning sauce, degassed at 90℃ for 3 min and vacuum-sealed using a double seamer under a 20 cmHg vacuum. The canned roasted oyster added with tomato paste sauce was prepared similarly by adding the same amount of tomato paste sauce instead of tomato sauce. Microbial growth, appearance, proximate composition, pH, volatile basic nitrogen (VBN), thiobarbituric acid (TBA) value, amino-N, salinity, color value, texture, free and total amino acids, and minerals were measured in the two products. A sensory evaluation indicated that the canned roasted oyster added with tomato paste sauce had preferable characteristics over the canned roasted oyster sauce added with tomato sauce.
