Key words: eight-treasure porridge bowl, plastic bowl, oxygen transmission rate, oxygen permeability, container oxygen permeability
Eight-treasure porridge, also known as Laba porridge, is a traditional festival food in China. The eight-treasure porridge is gradually becoming a food for daily health and fitness because of its selection of materials, rich nutrition, soft and sweet taste, and health benefits. However, the cooking of traditional eight-treasure porridge is time-consuming and labor-intensive, and it is inconvenient to carry, and it is no longer suitable for the fast-paced life. To this end, the company has developed an independent packaging type of eight-treasure porridge, and began to market.
The eight-treasure porridge is rich in nutrients, has sufficient water, and contains no preservatives. Its environment is an ideal place for microbial reproduction. During transportation and storage, the infiltration of oxygen accelerates the corruption, mildew and fermentation of the eight-treasure porridge, which deteriorates the food and is inedible. To this end, enterprises usually adopt certain preservation technology and high-temperature sterilization measures, and also choose packaging materials with high oxygen barrier properties to seal and store oxygen, so as to eliminate microorganisms, destroy their growth environment and extend shelf life. As far as the eight-treasure porridge itself is, it is a good base for microorganisms and belongs to perishable foods. Therefore, enterprises must choose packaging materials with good oxygen barrier properties to ensure the shelf-life quality of the eight-treasure porridge products.
There are two types of packaging in the market, eight-treasure porridge: tinplate cans and plastic bowls. Tinplate cans are generally packaged in three-piece tinplate, excellent barrier and sealing performance, but high material cost; plastic bowl packaging uses a lower cost plastic matrix, which can lead to plastic molding due to different types of plastics and processing methods. After the overall oxygen barrier performance shows a difference, it is necessary for enterprises to strengthen the detection of oxygen barrier properties of plastic bowl packaging. This will combine, Labthink OX2 / 230 Oxygen permeability oxygen permeability test systems detection disposable plastic bowls of rice pudding is described in detail.
At present, there is no clear standard for the container oxygen permeability test in China, so the ASTM F 1307 standard is generally adopted when conducting the container oxygen transmission rate test . The use of plastic bowls of rice pudding detection of Labthink OX2 / 230 oxygen transmission rate test system. Device complies with GB / T 19789, ASTM D3985, ASTM F2622, ASTM F1307 test standards, etc., for plastic film, high permeability material, solar energy back, sheet, composite materials, aluminized, film or co-extruded film, aluminum foil Oxygen transmission rate test of packaging materials such as bottles, bags, cans, boxes, etc. for sheet materials and plastics, rubber, paper, glass, and metal. OX2/230's unique container test chamber, equipped with a special special container sealing device, sealed with a transparent quick-fixing glue on the container sealing device, sealed on the OX2/230 after sealing, and then sealed The bag wraps the area above the container closure device tray. The test process is simple to operate. After the sample is clamped, set the experimental parameters to start the test. The entire test process is automatically completed without manual intervention and the test results are displayed in the software.
The oxygen transmission rate of the disposable plastic eight-treasure porridge bowl can directly reflect the oxygen barrier performance of the product, affecting the shelf life quality of the product. In addition to the need to test and control the oxygen permeability index of plastic bowls, enterprises need to control the water vapor transmission rate of packaging and the heat sealing strength of packaging to ensure the quality of products during the shelf life.
