- Abstract
Soxhlet extraction method was used to extract oil from flaxseed of different varieties and producing areas in Qinghai province. The volatile components of flaxseed oil were enriched by headspace solid phase microextraction (SPME) and determined by gas chromatography-mass spectrometry (GC-MS). The volatile components of 40 batches of samples were analyzed and a fingerprint was constructed to identify the flaxseed oil samples mixed with sixkinds of vegetable oil in different proportions. The results showed that Qinghai flaxseed oil samples contained 58 volatile components, among which aldehydes were the main flavor components. In addition, the chromatogram of six kinds of vegetable oil were less similar to the standard fingerprint of flaxseed oil, the difference provided the feasibility for the identification of adulterated flaxseed oil. The adulteration model established is suitable for theidentification of flaxseed oil adulterated with 10% peanut oil, sunflower oil, sesame oil, more than 20% corn oil, more than 30% rapeseed oil and more than 40% soybean oil. This study provided a theoretical basis for the adulteration identification and quality control of flaxseed oil.
