Are metal utensils harmful to the body?
Non-toxic, lightweight and durable, high quality and low price, but too much aluminum accumulates in the human body, which has the effect of accelerating aging and has a certain adverse effect on human memory. Aluminum tableware is not suitable for cooking acidic and alkaline foods, nor for long-term storage of meals and long-term storage of salty foods.
Iron and aluminum tableware should not be used together. Because aluminum and iron are two metals with different chemical activities, when there is water, aluminum and iron can form a chemical battery. bring greater harm to human health.
Alloy tableware mainly refers to tableware produced with PPS and SPS materials. PPS has the advantages of high temperature resistance, corrosion resistance, radiation resistance, flame retardant, balanced physical and mechanical properties, excellent dimensional stability and excellent electrical properties. Alloy tableware on the market is mainly alloy chopsticks. Compared with chopsticks of other materials, alloy chopsticks have the advantages of high temperature non-deformation, easy cleaning, not easy to mold, not easy to absorb microorganisms such as Escherichia coli, durable and corrosion-resistant. Alloy chopsticks are safe and hygienic, and will not produce harmful substances under high temperature. Since PPS and SPS are imported materials, the price is slightly higher. In China, most of them are gifts and high-end hotels using alloy chopsticks made of this imported material.
Stainless steel cutlery
Beautiful, light and easy to use, corrosion-resistant and not rusted, it is very popular. Stainless steel is made of iron-chromium alloy mixed with nickel, molybdenum and other metals. Therefore, when using it, you should pay attention not to store salt, soy sauce and vinegar for a long time. etc., because the electrolyte in these foods will react with stainless steel for a long time, so that harmful substances will be dissolved out.
