An Infraspec VFA-IR spectrometer analysis of Trans-fat content in glazed donuts purchased from supermarkets, convenience stores and bakeries

摘要

Most packaged food products must contain trans-fat labelling; however unpackaged snacks such as cookies, donuts, and muffins at supermarkets, gas station convenience stores, and bakeries often do not have or require nutrition fact labels. Hence, consumers are not aware of the trans-fat content in unpackaged food products. It is well-known within the health and scientific community that diets high in trans-fat can lead to a host of health problems, namely coronary heart disease (CHD). The purpose of this study is to conduct a preliminary study of the trans-fat content in unpackaged baked goods, particularly unpackaged glazed donuts. To accomplish our objective, we determined the % trans-fat in oil extracted from glazed donuts obtained from several supermarkets, gas stations and bakeries across Northwest, Indiana. Variable Filter Array (VFA) IR spectroscopy was used to assess the trans-fat content of oil extracted from food samples. In this paper, we present our preliminary findings
