本文研究了贮藏在0℃下黄瓜的冷害与时间的关系,测定了0℃和20℃下黄瓜中氨基酸种类、含量及其贮藏中的变化,结果表明,上述2种温度对谷氨酸、丙氨酸及总氨基酸含量的影响最大,0℃下受冷害黄瓜中丙氨酸含量及丙氨酸占总游离氨基酸的百分比要比在20℃下贮藏的高,而谷氨酸含量及其占总氨基酸含量的百分比却比20℃下的要低。
In this paper, the relationship between the chilling damage and the time of cucumber stored at 0 ℃ was studied. The types, contents and storage of amino acids in cucumber at 0 ℃ and 20 ℃ were measured. The results showed that the above two kinds of temperature had significant effects on glutamic acid, The contents of alanine and total amino acids in chilling cucumber were the highest at 0 ℃, and the contents of alanine and alanine in the chilling cucumber were higher than those stored at 20 ℃, while the contents of glutamic acid and its total The percentage of amino acid content is lower than at 20 ° C.
