아이스크림 제품류에 함유되어 있는 지방함량 및 지방산조성

Abstract

The objective of the study was to analyze the contents and fatty acid compositions in the extracted fats from selected commercial ice creams and ice cream-related products. Seventy four ice creams and ice cream-related products were collected from local stores: 22 regular `ice creams`, 10 premium `ice creams`, 22 `ice milks`, 4 `sherbets`, 11 `non-milk-fat ice creams` and 5 `non-milk product ice creams`. Contents and fatty acid compositions of the fats in the ice creams and ice cream-related products were analyzed. Fat contents in regular `ice creams`, premium `ice creams` and `ice milks` were , respectively. `Sherbets`, `non-milk-fat ice creams` and `non-milk product ice creams` contained fats, respectively. Fats extracted from 14 regular `ice creams`, all of the premium `ice creams` and 11 `ice milks` contained saturated fatty acids and trans fatty acids. Their fatty acid compositions were similar to those in milks and butter. However, fats from 8 regular `ice creams` and 11 `ice milks` contained lauric acid, respectively. Since these levels of lauric acid were 3 times more than in milk or butter, other fats along with milk fat might be used for manufacturing these` ice creams` and `ice milks`. Out of these 19 products, only 5 products were labelled as `coconut oil` or `refined oil` as well as milk fat being used. Fats extracted from `sherbets`, `non-milk-fat ice creams` and `non-milk product ice creams` contained saturated fatty acids, respectively. Lauric acid was the most abundant fatty acid in the fats of these products, being of the total fatty acids, respectively.
