Now silicone kitchenware by fashion enthusiasts, the State administration of quality Supervision, inspection and quarantine issued a notice to remind the health risks of food silicone products: In the process of repeated use of silicone products, found that its appearance or physical performance changes should be replaced in a timely manner. Also pay attention to identify the plastic products posing as silicone.
Silicone products for food with silicon-oxygen (SI) key chain structure, chemical stability, can be in the temperature range of 40 ℃ to 180 ℃ of the conditions of re-use. In recent years, food silicone products in various fields have been widely used, such as silicone shovel,silicone kitchenware silicone scraper, silicone mold, silicone steamer mats. Although the silica gel material is relatively safe, but in the purchase and use there are some noteworthy places.
First of all, should observe whether the product has peculiar smell. If the product has a pungent odor, it should be carefully purchased. silicone kitchenwarewith the hand to stretch the product, observe whether the tension is transparent, transparent products are more high-quality, in use is not easy to produce small molecule material migration.
In the process of reusing silicone products, it is found that the appearance or physical properties change, such as swelling, discoloration, surface viscosity, hardness, elasticity, etc., should be replaced in a timely manner. Because changes not only affect their performance, but also more easily degrade the formation of small molecular substances,silicone kitchenware small molecule substances are easier to migrate to food, resulting in quality and safety risks.
Not only experts said that food grade silica gel is safe, silicone insoluble in water and any solvents, non-toxic tasteless, and chemical properties of stability. The most common home is the pressure cooker used to seal the gasket, is the food grade silicone. Easy to clean, not easy to breed microorganisms, but it is best not to use more than 3,500 hours.
But because the cost of silicone pad is more expensive, do not rule out illegal businesses with polyvinyl chloride (also known as PVC or plastic) to replace. Food grade silicone pad price is higher,silicone kitchenware like a few dollars sold on the shop, it is likely to be plastic. Plastic itself is unstable, and in the processing process will use similar plasticizer, such as additives, in the case of high temperature, this kind of additive easily volatile out, endangering human health.
Plastic and silica gel is not good,silicone kitchenware the first choice to buy a reliable brand, but also from the following aspects to identify:
Color: Steamer Mat silicone material General choice edible grade silica gel, silica gel divided into industrial grade and food grade and recycling glue, consumers encounter too cheap products must be careful. Silica gel Color Natural white, not particularly white, if the color is particularly bright white,silicone kitchenware you should be careful whether plastic products, or add some additives in order to whiten brightening. It's hard to tell if it's a color product.
Taste: Plastic silicone pad to get a very strong after the taste of plastic, if you encounter such a situation, must not use. Real silicone material is tasteless, in the low temperature-60 ℃, High-temperature 180 ℃ cases are safe to use.
