摘要
目的:提高小龙虾副产物的产品附加值。方法:以色谱峰个数和峰面积为指标,对平衡时间、氯化钠添加量、萃取时间及萃取温度进行工艺优化,并分析其挥发性风味物质成分。结果:使用50/30μm DVB/CAR/PDMS固相微萃取头,在平衡时间0 min、萃取温度75℃、萃取时间50 min、氯化钠添加量30%条件下,小龙虾加工水煮液中可检测出34种挥发性风味成分(醇类5种,醛类12种,烷烃类5种,芳香族化合物5种,杂环化合物5种,酯类2种),总峰面积为5.54×10^(8),综合得分为95.47分,与预测值相比,相对误差为4.53%。结论:顶空固相微萃取法可萃取出小龙虾加工水煮液中34种挥发性风味物质。
Objective:In order to increase the added value of crayfish by-products.Methods:With chromatographic peaks and peak areas as the inspection indicators,the optimization on equilibrium time,addition of sodium chloride,extraction time and extraction temperature were optimized,and the composition of volatile flavor compounds was analyzed.Results:The optimal extraction conditions were equilibrium time 0 min,extraction temperature 75℃,extraction time 50 min,addition of sodium chloride 30%with 50/30μm DVB/CAR/PDMS solid phase microextraction head.Under these conditions,a total of 34 volatile flavor compounds,including 5 alcohols,12 aldehydes,5 alkanes,5 aromatic,5 heterocyclic compounds and 2 esters,were detected in the crayfish boiled liquid.The total peak area was 5.54×10^(8),and the comprehensive score was 95.47.The relative error between the experimental results and the predicted value was 4.53%.Conclusion:The 34 volatile flavor compounds can be extracted from the crayfish boiled liquid by headspace solid phase microextraction.
