1.前言 食品中,油脂食品和含色素的食品在流通过程中,由于受光线和氧气的影响,会因形成氧化而变质,造成味觉降低、变色退色等质量问题。采用铝箔包装材料,是防止上述问题的最可靠手段。这种材料可同时阻断光线和气体。例如,以咖喱为代表的提纯食品,保存期必须长达两年,其包装采用铝箔和塑料薄膜层压袋。在只需要考虑对内容物进行保护的情况下,使用铝箔包装最好。然而,由于近几年消费者需求多样化和对商品的差别化的要求越来越高,在对内容物进行保护的同时,也趋向于提高商品的价值。具体来说,要既能用电子灶加热,又要能看到其中的食品。
1. Introduction Food, food and food containing fat in the distribution process, due to the impact of light and oxygen, due to the formation of oxidation and deterioration, resulting in lower taste, discoloration and other color quality problems. The use of aluminum foil packaging materials, is to prevent the most reliable means of the above problems. This material blocks both light and gas. For example, purified foods, such as curry, have a shelf life of up to two years and are packaged in aluminum foil and plastic film laminate bags. In the case of only need to consider the contents of the protection, the best use of aluminum foil packaging. However, due to the diversification of consumer demand and the increasing demand for the differentiation of commodities in recent years, the content protection has been accompanied with the promotion of the value of commodities. Specifically, to use both electric stove heating, but also to see the food.
