Method for detecting rape honey aroma components by solid phase microextraction

Abstract

The invention relates to a method for detecting rape honey aroma components by solid phase microextraction, and the method comprises the following steps: weighing 6 mL of rape honey, adding 400 mg of sodium chloride, aging an extraction head at an introduction port of a gas chromatograph at an aging temperature of 250 DEG C for 2 hours, inserting the aged extraction head into a headspace part of a sample bottle, pushing a fiber head out, carrying out constant temperature magnetic stirring adsorption at 60 DEG C for 50 min, inserting the extraction head into a GC-MS introduction port, carrying out desorption at 250 DEG C for 5 min, and then carrying out gas chromatography-mass spectrometry. The method of the invention can rapidly detect aroma components in rape honey, and can identify whether the rape honey is adulterated by comparison with standard rape honey aroma substances.

Description

technical field [0001] The invention relates to a method for detecting aroma components of honey, in particular to a method for detecting aroma components of rapeseed honey by using solid-phase microextraction technology. Background technique [0002] Because honey has multiple health care functions, it is favored by consumers, and the market demand for honey is also increasing in recent years. Because single-flower honey is superior to mixed-flower honey in terms of quality and nutrition, it is favored by consumers. In order to obtain high profits, some unscrupulous traders use mixed-flower honey to pretend to be single-flower honey or use low-priced single-flower honey to pretend to be high-priced single-flower honey, or directly Adding extraneous sweet substances such as molasses to unifloral nectars. The honey adulteration incident has been exposed by the media many times, but the honey adulteration phenomenon has never stopped. This is a problem that all relevant manag...
