白菜包装纸的研究初探

以白菜为基本原料,添加不同的改性试剂制成蔬菜包装纸。通过考察成纸外观、柔韧性、力学性能等,得到较好的蔬菜包装纸配方。实验结果表明,添加了明胶、海藻酸钠、大豆蛋白以及明胶和甘油混合的溶液后,蔬菜包装纸的各方面性能均有不同程度的提高。添加明胶后蔬菜纸的强度和柔韧性均有一定程度的提高;添加海藻酸钠对白菜纸力学强度作用不明显,但可适当提高成纸的柔韧性;添加大豆分离蛋白后白菜纸的柔韧性提高,但外观变差;添加明胶和甘油的白菜纸各方面性能最优,且浸渍处理的方法好于直接添加改性试剂的成型方式。

A primary exploration of cabbage packaging paper

Cabbage as the basic raw materials,added different modification reagents are used to produce vegetable wrapping papers. By examining paper morphology,flexibility and mechanical properties,a better formula for making vegetable packaging has obtained. It can be found from experiments that introduction gelatin or giycerin or soy protein or alginate into cabbage wrappings has led to improved flexibility and increased mechanical strength. Adding gelatin into cabbage has improved mechanical strength and flexibili...
