摘要
以盐渍辣椒为原料,采用正交试验优化脱盐盐渍辣椒发酵工艺,用HS–SPME–GC–MS方法测定脱盐盐渍辣椒发酵前后挥发性成分的变化。结果表明:盐渍辣椒脱盐后,其氯化钠、总糖、总酸、还原糖、氨基酸态氮含量均有显著降低(P<0.05);脱盐盐渍辣椒发酵的适宜工艺为接种6%的植物乳杆菌菌液,添加4%蔗糖,发酵5 d;脱盐盐渍辣椒接种发酵后,其酯类、醛类物质相对含量分别较发酵前增加了24%、448%,醇类、烯烃类相对含量分别降低了18%、31%,接种发酵使辣椒中的酯类和醛类物质增加。
By taking salted chili as materials,the fermentation process in making desalted chili were optimized throughorthogonal experiment,and the change of volatile flavor components before and after fermentation were determined byheadspace solid phase microextraction gas chromatography and mass spectrometry(HS–SPME–GC–MS).The resultsindicated that NaCl,total sugar,total acid,reducing sugar and amino acid nitrogen content in desalted chili reducedsignificantly after desalination(P<0.05).The appropriate fermentation process of desalted chili was6%Lactobacillusplantarum,4%sugar,and fermentation for5days.The relative content of esters and aldehydes of inoculationfermentation desalted chili increased24%and448%respectively than desalted chili,while alcohols and olefins decreased18%and31%respectively.Inoculation fermentation was helpful to improve the flavor of esters and aldehydes in chili.
