摘要
用不同浓度的羧化壳聚糖溶液处理离体桑叶 ,间隔一定时间调查其保鲜效果 ,结果表明 :羧化壳聚糖具有防止桑叶失水 ,保持桑叶原色等保鲜效果 ,并能抑制桑叶呼吸强度 ,降低桑叶在贮藏过程中营养成分 (糖、蛋白质 )的损失。生物试验表明 :羧化壳聚糖不仅对家蚕的生长发育无不良影响 ,而且在一定程度上能提高眠蚕体重、全茧量、茧层量、茧层率和健蛹率等。此外 。
Detached mulberry leave were treated with different concentration of N-carboxymethylchitosan (NCMC) to investigate the effect on the fresh preservation. The results showed that NCMC could reduce the loss of the chlorophyll, inhibit breathing intensity and decrease the loss of the nutritious materials, such as carbohydrate and protein. Biological assay showed that NCMC had no bad influence on growth and development of silkworm, but could increase the molter body weight, cocoon weight, cocoon shell weight, cocoon shell rate and good pupa rate. Moreover NCMC had good effect on inhibiting three bacteria of silkworm.
