低温贮存对桑叶蛋白质含量的影响

本文以云桑一号的桑叶为实验材料,在不同的冷藏温度和冷藏时间条件下,对不同种植模式和不同叶位的桑叶进行冷藏处理,测定桑叶中蛋白质含量,分析蛋白质的变化规律。结果表明:在0℃和10℃贮藏温度条件下,各类型桑叶贮藏8天后,0℃时桑叶蛋白质含量明显高于10℃时桑叶蛋白质;四边桑蛋白质含量明显高于校园桑和密植桑,上部叶中蛋白质含量明显高于中、下部叶片;随着贮藏时间的延长,各类型叶片的蛋白质平均含量均呈下降趋势,下降速率从快到慢依次为:四边桑上部叶、校园桑上部叶、四边桑中部叶、密植桑上部叶。

Effect of Cold Storage on Mulberry Leaf Protein Content

This paper took the mulberry leaves of Yun-sang NO.1 as experimental material, under the conditions of different cold storage temperature and different cold storage time, refrigerated the mulberry leaves of different planting patterns and different leaf position, measured the protein content in mulberry leaves, analyzed the changing rule of the protein. The results show that under the zero and hundred degrees centigrade of storage temperature conditions, each type of mulberry leaves storages eight days later, the protein content in the zero degree centigrade is significantly higher than that in the hundred degree centigrade ; the protein content of quadrilateral mulberry is significantly higher than that in the campus mulberry and dense planting mulberry, the protein content of upper leaves is significantly higher than that in the middle leaves and lower leaves; with the extension of storage time, the average protein content shows a downward trend, from fast to slow as follows： upper leaves of quadrilateral mulberry, upper leaves of campus mulberry, middle leaves of quadrilateral mulberry ,upper leaves of dense planting mulberry.
