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 $5{\sim}11%,\;13{\sim}17%\;and\;2{\sim}10%$, respectively. 'Sherbets', 'non-milk-fat ice creams' and 'non-milk product ice creams' contained $2{\sim}7%,\;4{\sim}11%\;and\;1{\sim}2%$ fats, respectively. Fats extracted from 14 regular 'ice creams', all of the premium 'ice creams' and 11 'ice milks' contained $63{\sim}75%$ saturated fatty acids and $2{\sim}5%$ 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 $11{\sim}28%\;and\;11{\sim}34%$ 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 $81{\sim}92%,\;76{\sim}99%\;and\;84{\sim}99%$ saturated fatty acids, respectively. Lauric acid was the most abundant fatty acid in the fats of these products, being $33{\sim}34%,\;17{\sim}45%\;and\;27{\sim}46%$ of the total fatty acids, respectively.
