The dried fruit roasted and roasted products are rich in nutrients, rich in protein, carbohydrate, vitamin A, vitamin E, vitamin B1, vitamin B2, and various mineral elements necessary for the human body. Very popular with consumers. In recent years, with the economic development and the improvement of people's living standards, dried fruit food has become a daily consumer and leisure interest for many consumers, thus prompting the rapid development of the production and sales scale of the dried fruit industry. But at the same time, the industry is also facing a problem of product quality and food safety - products are susceptible to oxidative deterioration.
The most popular dried fruit products on the market today are peanuts and seeds. Because of its high content of oils and fatty acids, it is prone to oxidation and deterioration of products caused by excessive peroxide values in the sales process, causing food safety problems. problem. Because the oxidation of products is an irreversible reaction, the occurrence of problems will not only bring harm to the health of consumers, but also cause waste of products, which will have a serious negative impact on the corporate brand and reputation. The basic requirement for dried fruit packaging is to separate oxygen and water, because seeds and peanuts are easy to absorb moisture. If the moisture barrier property is poor, the seeds will absorb moisture and degenerate and accelerate the oxidation of the oil; the deoxidizer and antioxidants are used in the seeds. The antioxidants themselves can delay the oxidation of the oil to a certain extent. If the oxygen barrier performance of the packaging bag is poor, oxygen will continue to infiltrate into the packaging bag, then the antioxidant, antioxidant and its own antioxidant composition will Quickly loses its antioxidant effect. Therefore, the material of the dried fruit packaging bag is very important for the shelf life of the roasted seeds and nuts. Currently, some brands of the product on the market generally use materials with good barrier properties. For example, the packaging material of a certain brand is PA/PE, which is a very perfect vacuum packaging. Vacuum is used to reduce the oxygen content in the packaging, prevent deterioration of the packaged food, maintain the color and flavor of the food, and extend the shelf life. Can also be applied to aluminum plating material, PET/VMPET/PE, this kind of material has lower oxygen permeability and certain burst resistance. Moreover, the composite package is beautifully printed and beautifully bagged, and it is highly favored by consumers. Improve the economic efficiency of enterprises.
