There are many kinds of Chinese food in daily life, but the two tableware raw materials that have been used the longest are stainless steel tableware and silicone tableware. Which one is better? Below is a summary of stainless steel cutlery and silicone cutlery.
Research reports on tableware show that trace metal elements in stainless steel also slowly accumulate in the human body.
When it reaches a certain limit, it will endanger human health. Therefore, the following points must be paid attention to when using stainless steel kitchen utensils. 1. Don't put salt, soy sauce, vegetable soup, etc. for a long time, because these foods contain a lot of electrolytes.
Stainless steel will also electrochemically react with these electrolytes like other metals if left for long periods of time, dissolving toxic metal elements. 2. Chinese medicine cannot be boiled in stainless steel utensils, because Chinese medicine contains many alkaloids, organic acids and other ingredients, especially under heating conditions, it is difficult to avoid chemical reactions with them, which will make the medicine invalid or even produce some more toxic substances. compound. 3. Do not wash with strong alkaline or oxidizing chemicals such as soda water, bleach, sodium hypochlorite, etc., because these substances are electrolytes and will also chemically react with stainless steel.
Is the use of silicone tableware harmful to human health? Harmful substances in plastics will volatilize at high temperatures. The main raw material of silicone tableware is polystyrene. Polystyrene is non-toxic, hygienic and safe.
However, the residual styrene and some other volatile substances in the polystyrene resin polymerization process, including ethylbenzene, cumene, toluene, etc., have small molecular weights and certain toxicity. In particular, styrene monomer can inhibit the fertility of rats and reduce the average weight of liver and kidney. In addition, plastics are not easily recycled and decay, leading to land degradation.
In nature, the degradation cycle takes 200-400 years, and incineration will release a lot of harmful gases. In order to save costs, some manufacturers use other similar silicone materials to pretend to be silicone materials. They have similar hardness, feel and elasticity to silicone materials.
It’s hard to tell what’s true and what’s false intuitively. As a large-scale silicone kitchenware manufacturer at home and abroad, let's take a look at Shisheng Silicone and teach you how to identify the authenticity of silicone kitchenware. Discover how to identify silicone kitchenware.
First, in terms of characteristics In terms of characteristics, silicone kitchenware products are non-toxic and tasteless products with good texture and harmless to human body. Generally, fake silicone products are very good, and silicone foot pads achieve these effects. Fake and shoddy silicone products are generally toxic, pungent and rough! 2. In terms of feel In terms of feel, the toughness and elasticity of silicone kitchenware products are very good.
It is not easy to be permanently deformed by external force, and the hand feel will be smoother. Fake silicone products are easy to deform and feel rough, because there is no layer of grease-like substances on the surface of fake silicone. 3. Burn with fire At the same time, we can also burn real and fake silica gel through flame, which is also very useful.
Fake silicone kitchenware products emit black smoke when they burn, and the residue is black powder. Real silicone products will produce white smoke when burning, no matter what color, the burning residue is white powder. 4. Chemical test Burn the silicone rubber, contact the smoke with a watch glass, collect the white powder, dissolve the powder in a hot solution of 40% strong alkali (60°C), drop one drop of the solution into the test tube, add two drops of ammonium molybdate, slightly heat, cool , add 3 drops of aniline solution and 8-8 drops of saturated sodium acetate solution, observe the color reaction of the solution.
If there is blue, it means that there is silicon element, which proves to be silica gel.
