不同贮藏温度对低温压榨核桃油 关键香气成分的影响Effects of different storage temperatures on key aroma components of cold-pressed walnut oil

open access: yesZhongguo youzhi
旨在为核桃油的低温贮藏提供参考,研究了不同贮藏温度下低温压榨核桃油关键香气成分的差异。将低温压榨核桃油在25、4、-10、-20 ℃下贮藏8周,考察贮藏过程中其酸值和过氧化值的变化,采用电子鼻与固相微萃取-气相色谱-质谱法测定核桃油的风味物质与挥发性成分含量,并采用相对气味活度值确定关键香气成分。结果表明:随着贮藏时间的延长与贮藏温度的升高,低温压榨核桃油的酸值和过氧化值升高,但均未超出国标限量;电子鼻分析表明,低温压榨核桃油主要含有氮氧化物、烃类、萜烯类、硫化物、醇类、醛酮类等物质,-20 ...
