正确使用自封口袋来贮存果蔬

发布日期:2022-09-01 作者:www.jnsuliao.com 点击:

今天由济南自封口袋厂家来教一下大家正确贮存果蔬的方法,大家可以作为参考。
Today, Jinan self sealing bag manufacturer will teach you how to store fruits and vegetables correctly, which can be used as a reference.
蔬菜水果为有机食品,含有水溶性营养物质和酶类。在贮存期间仍迸行着很强的呼吸活动。贮存的时候要注意一下几点:
Vegetables and fruits are organic food, containing water-soluble nutrients and enzymes. Strong respiratory activity still occurs during storage. Pay attention to the following points during storage:
在有氧的条件下,果蔬中的糖类或其他有机物质氧化分解,产生二氧化碳和水分,并放出大量熟量;在缺养的条件下,糖类不能氧化,只能分解产生酒精、二氧化碳,并放出少量热量。
Under aerobic conditions, sugars or other organic substances in fruits and vegetables are oxidized and decomposed to produce carbon dioxide and water, and a large amount of ripeness is released; Under the condition of lack of nutrition, sugars cannot be oxidized, but can only be decomposed to produce alcohol and carbon dioxide, and release a small amount of heat.
要想将果蔬放在自封口袋里贮存,隔两三天把自封口袋的口打开,放出二氧化碳和热量,再把口扎上,这样就会减少腐烂变质现象的发生。二氧化碳浓度不能无限度地上升,只能提高10%。氧浓度的下降也不能超过5%,因缺氧呼吸产生的酒精留在果疏里,会引起果疏腐烂变质,所以果蔬放自封口袋内存放时间不宜过长。
If you want to store the fruits and vegetables in the self sealed bag, open the mouth of the self sealed bag every two or three days to release carbon dioxide and heat, and then tie the mouth, so as to reduce the occurrence of decay and deterioration. The concentration of carbon dioxide can not be increased indefinitely, but can only be increased by 10%. The decrease of oxygen concentration should not exceed 5%. The alcohol produced by hypoxia respiration will stay in the fruit tree, which will cause the fruit tree to rot and deteriorate. Therefore, the storage time of fruits and vegetables in self sealed bags should not be too long.

此外我们来了解下自封口袋的原材料:
In addition, let's learn about the raw materials of self sealing bags:
PP料:料身较硬,但透明度对比高,较清楚,拉力不是很好!易爆口!
PP material: the material body is hard, but the transparency is high and clear, and the tension is not very good! Explosive mouth!
PO料:料身较脆,透明度不够高,比PE料还要蒙,有点透红色,拉力也不是很好。
Po material: the material body is brittle, the transparency is not high enough, and it is more opaque than PE material, a little red, and the tension is not very good.
OPP料:料身脆,透明度高,拉力不够,但易爆口。且印刷轻易脱色。
Opp material: the material body is brittle, high transparency, insufficient tension, but explosive. And the printing is easily decoloured.
PVC料:料身有软也有硬的,可依据主人所需来订料,透明度也可根椐所需。
PVC material: there are soft and hard materials, which can be ordered according to the needs of the owner, and the transparency can also be based on the needs.
