摘  要：
以新鲜小松菜为试材,采用小苏打复合液、乙酸锌复合液2种不同保绿途径对其冻藏前进行烫漂处理,并对小松菜钙、钠、锌元素含量进行测定,比较了2种不同前处理消解方法精确性,研究了不同处理方法对冻藏期小松菜相关品质指标的影响。结果表明:2种保绿途径均显著延缓了小松菜总叶绿素含量的损失(P<0.05),不同程度增加了样品中钙、钠、锌离子含量,其中金属离子保绿途径的乙酸锌复合液处理样品的锌离子残留量超标,相比而言,碱保绿途径的小苏打复合液处理对冻藏期小松菜相关元素残留安全性及护绿效果较好,处理时应避免长时间、高温烫漂对产品硬脆度的破坏而抵消复合液中钙离子的保脆效应。

摘  要：
The fresh komatsuna was used as raw material,the effect of compound sodium bicarbonate solution(alkali preserving green method)and compound zinc acetate solution(metal ion preserving green method)blanching treatments on the storage quality of post harvest komatsuna were studied,and the effect of different pretreatment methods on the detection accuracy of element content to komatsuna was discussed by determining of calcium,sodium,zinc content.The results showed that the alkali preserving green method and the metal ion preserving green method could significantly inhibit the loss of total chlorophyll content(P<0.05)and enhance the zinc,calcium,sodium element content of the samples to different extent,however there was the excessive zinc residue in the samples blanched by compound zinc acetate solution as metal ion preserving green method,on the whole,the alkali preserving green method was better than the metal ion preserving green method in preserving green and reducing excessive ion(such as zinc)residue of the test samples.There shall pay more attention to the blanching factor of avoiding high temperature and long minutes than to the factor of calcium treatment in order to protect brittleness.
