시판 레토르트식품의 지방함량 조사- 조지방, 포화지방, 트랜스지방산 중심으로

Abstract

The aim of this study was to provide nutrition information to consumers by analyzing crude fat, saturated and trans fatty acids in commercial retort foods (n=70). The following sauce products of curries (n=21) and black-bean-sauces (n=16), other sauces (n=17) and instant cooking foods (n=16) were collected. Crude fat contents were quantified with the Rose-Gottlieb method using acid digestion. While saturated and trans fatty acids were examined by gas chromatography with a flame ionization detector (FID). Crude fat, saturated and trans fatty acid content ranges were 0.47±0.42~12.80±0.07 g/100 g, 0.24±0.02~17.41±0.41 g/100 g, 0.00±0.00~0.46±0.05 g/100 g, respectively. Maximum recovery of analysis values was crude fat (119.7%), saturated fat (119%) and trans fatty acid (90%) compared the actual amounts based on the reference value indicated on the nutrition label. The analyzed samples were found to be compliant with nutrition label standard, because the contents of crude fat, saturated fatty acid, trans fatty acid were less than 120% of the reference value indicated on the nutrition label in retort foods. Therefore, the nutrition information on retort foods available to consumers was found to be trustworthy.
