摘要
采用溶液萃取法对超高压处理前后的猕猴桃汁的香气进行富集,并经GC/MS联机检索分析,发现超高压处理对猕猴桃汁中的酯类、羧酸类、醛酮类、醇类和杂环类都有影响,超高压后,酯类物质、醇类物质无论从种类和数量上都下降,而醛酮类、羧酸类和杂环类化合物无论从种类和数量上都增加。其影响作用和高压造成的温度升高有关。
The paper studies the differences in flavor compounds in kiwifruit fruit juice before and after ultra high pressure （UHP） treatment by combining solvent extract with GC/MS method. It was discovered that UHP process changed the peak areas and varieties of esters, carboxylic acids, aldehydes-ketones, alcohols and heterocycles. The decrease in peak areas and varieties of esters and alcohols after UHP treatment were observed while the peak areas and varieties of carboxylic acids, aldehydes -ketones, and heterocycles were increased. The effects of UHP on volatile components were correlated to the increase of temperature.
