Wuhan Handern food packaging materials for radiation sterilization
With the prosperity and development of our economy. People's living standards are getting better and better. In order to better preserve various foods, which are fresh fruits, meat, eggs, etc., various packaged radiation sterilization methods are used. In recent years, the sterilization and preservation of food has been studied and applied in many research institutions and factories, regardless of the effect; this is the first step in the new preservation method of food in my country. www.handern.com Hollow board equipmentThe radiation sources are basically the following: (1) ultraviolet radiation sterilization; (2) C7 ray sterilization and preservation: (3) high-energy electron exposure sterilization: (4) X-ray radiation sterilization, and now C" radioactive rays have been used Irradiation of dry wine not only makes the wine mellow and delicious, but also reduces the bitterness and bitterness. This radiation is carried out in a non-toxic plastic container, with a dose of 200,000 to 400,000 lats, the dose rate is 5000 to 500,000 lat (hour) www.handern.com hollow board equipment
The Radiation Research Institute of Wuguo City Institute of Light Industry has adopted C radiation for fresh fruits (such as citrus extract) for two years, and has achieved good economic results every year. At the end of 1983, they irradiated 5 kilograms of orange withered in Yangmei Village, Taichao Commune, Wuguo City. Unfortunately, they were irradiated in a large basket and without any airtight packaging. The irradiated citrus can be placed in March and April after the Spring Festival. The effect is very significant, and there is no moldy deterioration. However, because there is no outer packaging, the citrus loses moisture and the orange peels dry. If it can be packed in a plastic bag and irradiated, it can not only ensure that it is not moldy, but also retain moisture and improve nutritional value. . When irradiating fruits with 7 rays, Kaifeng City, which uses 1-3 million roentgens, also set up a factory specializing in food processing, called Kaifeng Food Nuclear Energy Irradiation Factory. The solution to Tibetan packaging, melons and fruits, beverages, medicinal materials, meat, fish, game and local foods, fast foods, travel foods, etc., the packaging materials they put forward are: www.handern.com hollow board equipment
(1) Non-toxic
(2) Can withstand 10kGy (million lun) ray irradiation without deterioration and modification. www.handern.com Hollow board equipment
(3) Good air and moisture barrier. www.handern.com Hollow board equipment
(4) Good tear resistance and tensile strength
(5) A temperature of 20～+110℃
It has been studied that after sterilization by accelerated electron irradiation, plastic packaging materials will produce low-molecular organic compounds of various components, such as ethyl acid, toluene, hydrocarbons, etc. These materials will cause packaged food Dyed with a certain smell, which affects the color and fragrance of food. For this reason, as an inner sealing layer of polyethylene, how to reduce and remove these odors is an important issue. After research, it is much better to use LLDPE as the inner sealing layer than LDPE. The odor can be greatly reduced. If the food is irradiated with hydrogen in mind, it can reduce the formation of odorous substances. Therefore, at present, compounding with LDPE as the inner sealing layer, irradiating food with accelerated electrons in nitrogen-filled packaging is a better process. www.handern.com Hollow board equipment
