Abstract:
Rape was used as test material,the effects of natamycin combined with calcium propionate treatment on quality and flavor substances of rapes during different storage in refrigerator by measuring the weight loss rate,chlorophyll content and so on,and using the headspace solid-phase microextraction GC-MS and electronic nose technology were studied.The results showed that natamycin combined with calcium propionate could effectively inhibit the increase of weight loss of rape （P<0 05),and significantly decrease the rate of green color,firmness,soluble solids content,vitamin C content and chlorophyll content of rapes （P<0 05).A total of 46 flavor substances were found in rapes,including alcohols,esters,aldehydes,ethers,hydrocarbons and others.The volatile components of rapes were mainly composed of alcohols and aldehydes.Among them,leaf alcohol and almond were the main contributors of rape flavor.On the whole,the content of flavor substances in rapes during the storage of refrigerators was increased by alcohols and ethers,and the esters and aldehydes were reduced and the hydrocarbons did not change obviously.The Nata+CP group significantly inhibited the increase of alcohols,the decrease of esters and aldehydes,and enhanced the increase of ether species.In addition,LDA method could discriminate the difference storage period rapes by electronic nose.
