Development of activated carbon preservative paper and research of its preservative effect
-
摘要: 将孔隙发达、比表面积大、吸附能力强的活性炭粉末作为保鲜剂,利用高锰酸钾饱和溶液负载,采用纸浆内添加保鲜剂的方法研制保鲜纸。对番茄进行保鲜效果实验,结果表明:实验组呼吸速率明显低于对照组(p<0.05),且将果实呼吸高峰推迟了3~5d;实验组果实的可滴定酸和硬度下降速率明显减慢(p<0.05);可溶性固形物变化速率显著滞后于对照组(p<0.05);失重率增大速度明显变缓(p<0.05)。保鲜纸显著地延缓了番茄果实的成熟,保鲜效果显著。Abstract: Activated carbon have the character of well- developed pore structure, surface area, adsorption. So preservatives can be made by putting active carbon into saturated potassium permanganate solution.Preservative paper was developed by the method of putting preservatives into pulp. Then preservative paper's preservative effects was tested. The results showed that preservative paper could slow down tomato's senile apparently, the respiratory rate of experimental group was lower than the control group ( p < 0.05) and the preservative paper putted off tomatoes' s respiratory summit 35d; titratable acids and hardness of the experimental group declined more slowly than the control group ( p < 0.05) ; the change rate of experimental group's SSC was apparently lower than the control group ( p < 0.05) ; the experimental group's weight lose ratio became slower than the control group ( p < 0.05) .It turned out that the preservative paper has good preservative effects to delay fruits' ripening rate.
