摘要
以佛手为原料,利用单因素结合响应面法优化发酵工艺,采用顶空固相微萃取-气相色谱-质谱分析最优发酵条件下的佛手果醋香气成分。结果表明:佛手果醋在醋酸菌接种量8%、初始酒精度7%、发酵温度30.4℃、发酵时间4 d、初始pH4.7的条件下发酵的醋酸含量可达到(6.17±0.02)g/100 mL。佛手果醋中分析出31种香气成分,其中酸类物质5种(31.15%)、醇类物质7种(27.86%)、酯类物质9种(25.58%)、酚类物质4种(7.27%)、醛酮类物质4种(1.65%)、其他类物质2种(0.52%)。制得的佛手果醋具有明显的醋香和佛手果的清香,组织澄清,状态均匀,无杂质。
Using bergamot as raw material,the fermentation process was optimized by single factor combined with response surface method,and the aroma components of bergamot vinegar under the optimal fermentation conditions were analyzed by Headspace solid-phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS).The results showed that the acetic acid content of bergamot vinegar could reach(6.17±0.02)g/100 mL under the conditions of acetic acid bacteria inoculation amount of 8%,initial alcohol content of 7%,fermentation temperature of 30.4℃,fermentation time of 4 d and initial pH of 4.7.A total of 31 aroma components were identified in bergamot vinegar,including 5 acids(31.15%),7 alcohols(27.86%),9 esters(25.58%),4 phenols(7.27%),4 aldehydes and ketones(1.65%),and 2 other substances(0.52%).The prepared bergamot vinegar has obvious vinegar aroma and bergamot fragrance,clear tissue,uniform state,and no impurities.
