When you are looking for a spatula in the supermarket, which material do you choose?
Compared with metal spatula, silicone spatula can be bent and is more suitable for machine-bottomed pots. Its characteristics such as steam isolation, oil resistance, non-stick pan and durability are also loved by many cooking enthusiasts. Only when cleaning, pay attention to use a soft cloth and weak acid cleaner, do not use high toughness cleaning products such as steel balls.
How to maintain it? Kitchen utensils should be thoroughly cleaned and tidy before first use. After each application, use a soft cloth and detergent to clean and keep dry. Do not use high toughness cleaning products such as steel balls.
stainless steel spatula Stainless steel spatulas are the safer commodity of the bunch. Stainless steel spatulas have a high melting point. Don't worry about getting too hot to deform the stainless steel scraper and release harmful chemicals.
On the other hand, scientific research has shown that the moisture content of essential nutrients such as iron, chromium, and manganese is higher in ingredients cooked with stainless steel cookware than in other ingredients cooked with spatula. Therefore, the effective application of stainless steel spatula is beneficial to health. How to choose a better stainless steel spatula when you're in the supermarket? Tip: When choosing a stainless steel spatula, you can carefully observe its thickness to distinguish between good and bad.
Generally, a high-quality stainless steel shovel will be thickened into an arc shape at the part of the shovel head. The thickness is 2mm long, which makes the spatula closer to the shape of the pot without hurting the pot. The thickness of the fake stainless steel scraper is only 0.5mm.
This kind of shovel is very easy to bend when shovelling objects under high temperature, and there is a safety hazard of scalding. Stainless steel models and specifications can be seen when purchased together. At this stage, the comprehensive 304 stainless steel/316 stainless steel plate for food-grade material testing is.
How to maintain it? Do not soak stainless steel cookware in water for long periods of time, as it can easily reduce corrosion resistance. After the product is applied, add an appropriate amount of detergent, scrub with a soft towel or sponge, thoroughly absorb the moisture and store it, so that the kitchen utensils can be as new for a long time. What are the effects of the two on people's health? 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/ Do not 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.
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 ineffective, and even produce some more toxic compounds . Do not wash with strong alkaline or oxidizing chemicals such as soda water, bleach, etc. Because these substances are electrolytes, they 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.
