1 6 8 Vol. 6 No Journal of Food Safety and Quality Aug., 2015 * 叶少文 (, ) 摘要 : 目的方法, ;, 结果,,, 结论,,, ;, 关键词 : ; ; ; Studies of protein powder producing peculiar smell YE Shao-Wen * (By-Health Co., Ltd., Zhuhai , China) ABSTRACT: Objective To use orthogonal test in combination with gas chromatography, mass spectrometry to find out the reason and prevention measures of canned protein powder producing abnormal odor. Methods The volatile flavor substances of canned protein powder in different temperature, humidity of different time were tested by headspace gas chromatography mass spectrometry, so as to find out the source of protein powder producing the peculiar smell; the fatty acids in the canned protein powder were detected by gas chromatography, thus to find the reason of the protein powder producing peculiar smell. Results Canned protein powder under certain conditions were keeping at high humidity and temperature, the longer the storage time, the more likely it is to produce irritating odors and peculiar smell. The content of fatty acid in the normal protein powder is higher than that in the abnormal protein powder. Conclusion The fatty acid of canned protein powder is easily react with molecular oxygen under the high temperature and humidity, and produce a series of bad smell thing. It is effective to prevent the rancidity of fatty acid in protein powder, through controlling the temperature and humidity preservation, and ensure the nutritional value of protein powder.
