| The security requirement for food packing and development trend |
SANCHISAN COLOR DUMPLINGS 2007-5-10 |
Along with the socio-economic development and constantly improve living standards, there has been increasing emphasis on food hygiene and safety conditions. Food packaging food as an important component of the direct contact with the food, their health security is directly related to human health. To ensure food safety, the State Administration of Quality Supervision, 2006, the import and export of food packaging and implementation of the inspection record. Foreign packaging of food safety and quality requirements more stringent, at present, the United States, the EU, Japan and other developed countries for food packaging developed in accordance with the regulations, and implemented a strict market-access management. 1, the main food packaging safety requirements of food packaging materials mainly polyethylene, polypropylene, polyester, polyamide polymers and other materials. These packaging materials due to the molecular structure and molding process and added different agents showed a greater difference. Therefore, the food manufacturers to choose a suitable product packaging materials is particularly important, otherwise, there will be a food safety issue. For example, due to poor blocking material, it will shorten the shelf-life liquid milk or even of the time caused degeneration, For example preservation membrane in the absence of adequate ventilation can not guarantee that the amount of fresh vegetables. In order to maintain the flow of the process and fresh food safety and sanitation available to consumers, food packaging safety requirements are : (1)? solvent residues : packaging molding generally subject to Blow, printing, composite processes, to improve fitness and India increased speed, some would join the general solvent. Now the smell and potential toxicity of increasingly stringent requirements, national standards for solvent residues to less than 10mg/m2. (2)? Heavy metals : lead, cadmium, mercury, hexavalent chromium and other heavy metals, As they and their compounds toxic, but is a kind of biological accumulation of non-degradable substances. with the nature (water, soil, food chain), the characteristics of a cumulative, once absorbed by humans, humanity will not be able to pass their own metabolism excreted them and accumulate When accumulated to a certain volume will endanger human health caused by the human immune function and other serious consequences. (3)? Barrier properties : barrier property, including the blocking of the gas and water barrier, food spoilage of a majority is because the selected material barrier properties inappropriate. The choice of materials to be different from the enclosed, durability, storage conditions to choose a suitable barrier material. By the end of 2005 introduced the GB19741-2005 (liquid food packaging plastic composite membrane, standard package) packaging film Barrier proposed using GB/T1038 (plastic film permeability testing methodology) and GB/T1037 (plastic film and sheet water vapor permeability test methods) for testing. (4)? Tensile Properties : packaging film by the process of mechanical tension, the transport process will be squeezed, and other foreign powers. This requires Films must have sufficient tensile strength. For example composite membranes should ensure that no inter-layered film, which requires composite membranes have high peel strength, in order to avoid layered materials. (5)? Heat sealing properties : the production process more prone likelihood of closure, virtual closure seal leakage, sticky head, drawing, broken seal, heat sealing strength poor. It is noteworthy that the majority of filling production lines to achieve sealing filling the entire process for a relatively short time, At that time, the temperature had not yet fallen sealed room temperature, low intensity, which can easily leaked. So the sticky heat intensity (high temperature strength of the seal) anticipated for the entire filling process is particularly important. (6)? Ink Performance : food packaging film on the ink in addition to the general requirements and substrate adhesion, abrasion resistance, also resistant to sterilization and processing requirements boil, and resistance to cold, heat resistance and so on in order to ensure transport, Storage process will not happen ink particles. condensation phenomenon. Many ink containing harmful substances such as benzene. Second, food packaging materials development trend in recent years, Many domestic and foreign food researchers gradually shifted the focus of its research on edible packaging film. Development of the function of many different edible packaging film, such as soybean protein edible packaging film, chitosan edible packaging film, protein, fatty acids, starch composite edible packaging film, water-resistant protein films Okara to the raw materials for edible wrappers, edible packaging, packaging membrane protein maize (paper, the quality Tu), insect protein coating or film wrappings (or containers), corn starch or sodium alginate chitosan composite packaging film (paper). Biological plastic coating wrappings. Edible films can be packaged with edible food together, have some nutritional value, and some can be digested. Some edible film itself also has on human health role. But for a small amount of food packaging, food packaging monomer, direct contact with food to prevent food contamination. Edible films can be produced by adding some flavor, coloring agents, nutritional supplements, to improve food quality and sensory properties, increase appetite. Edible film and can be very convenient as a food flavor agent, ferment and food quality pigment-packaging materials, can effectively control the addition of these agents, release and stability. Edible films could also serve as preservatives, antioxidants carrier, in the food surface control their access to food within the speed, to reduce the amount of these additives. Edible film to be included in the internal heterogeneity food interface to prevent food components asked of water and solute movement and lead to food spoilage, food quality or impact. Edible films also can be used as a microwave, baked, fried food packaging coating. Meanwhile, edible film as a biodegradable film, without being consumed, in the environment can still be microbial degradation and will not cause environmental pollution. Currently, edible food packaging is the world's main industrial development trend, it has covered a wide range of application areas, sausage, wax fruit, sugar-coated, rice paper, clothing and ice coated tablets, and so on. As edible packaging functional diversity, environmentally sound, the materials for consumption, it has developed is developed, new products, new technologies are constantly emerging, and vast prospects for development.
