Food blister packaging It is a common packaging method, which combines packaging materials and food firmly by placing food in plastic packaging materials, heating with a blister machine and using negative pressure adsorption. food Blister packaging It has many advantages, such as abrasion resistance, anti-bacterial, gas blocking, fresh-keeping, etc., but some people doubt whether it will affect the nutrition of food. This article will discuss the impact of food blister packaging on food nutrition.

First of all, whether the food blister packaging has an impact on the nutrition of food needs to be determined according to the specific packaging materials and food characteristics. Common food blister packaging materials include polyethylene (PE), polypropylene (PP), etc. These materials have good wear resistance and moisture resistance, can protect food from the impact of the external environment, and reduce the oxidation reaction of food. However, some plastic materials will release harmful substances at high temperatures, which may have a certain impact on human health.

Secondly, food blister packaging may cause certain dissolution and migration of food nutrients. Food blister packaging materials are usually made by thermoplastic processing, which means that packaging materials may dissolve and migrate during heating. Dissolution means that water-soluble substances in food are absorbed by packaging materials and dissolved in packaging materials during heating, while migration means that dissolved substances in packaging materials enter food through diffusion, volatilization, etc. Both of these situations may lead to the loss of nutritional components of food. Some additives in plastic materials, such as preservatives and plasticizers, may also have a certain impact on the nutrition of food.

However, the impact of food blister packaging on food nutrition can be controlled by correctly selecting appropriate packaging materials and adopting appropriate processes. Choosing environmentally friendly and food specification plastic materials can reduce the chemical reaction between food and packaging materials and reduce the release of harmful substances. At the same time, reasonable control of heating temperature, packaging time and the area of packaging materials in contact with food can also reduce the loss of food nutrients. In addition, proper vacuum packaging and gas protection technologies can also maintain the nutritional content of food.

In general, the impact of food blister packaging on food nutrition is related to specific packaging materials, food characteristics and processing technology. Reasonable selection of packaging materials and control of process parameters can greatly reduce the loss of food nutrients. Of course, when purchasing packaged food, consumers should also pay attention to selecting brands and products with good reputation to ensure the safety and quality of food.

At the same time, the government and relevant regulatory authorities should also formulate strict standards and regulatory measures to supervise and inspect food blister packaging and packaging materials to ensure food safety and nutrition. In addition, strengthening the research and development of plastic materials and technological innovation, and promoting the use of more environmentally friendly and food safe packaging materials is also an important direction to reduce the impact of food blister packaging on food nutrition.

In short, Food blister packaging It may have a certain impact on the nutritional composition of food, but through proper selection of packaging materials, control of processing technology, strengthening supervision and other measures, the loss of nutritional composition of food can be greatly reduced. When purchasing packaged food, consumers should pay attention to selecting brands and products with good reputation, and the government and relevant regulatory departments should strengthen the supervision and inspection of food packaging materials to ensure the safety and quality of food.
