Everyone must have stainless steel tableware that has been used for more than ten years! Some are even durable enough to be a homemade treasure? For this expert, it is recommended that under normal use, it is recommended to change the new product after 3 to 4 years of use; and there are rumors that stainless steel tableware may cause poisoning. Is this really the case? Let’s take a look at some tips about stainless steel tableware.

Clean steel tableware will never get damaged, can it be regarded as a gifted treasure?

Collision-resistant and easy to clean stainless steel tableware is the first choice for many people when buying environmentally friendly tableware. But, do you know how to choose when buying stainless steel tableware? Do you need to change new products regularly? The Food and Drug Administration invited Assistant Professor Wu Junyi from the Department of Food Science at Ocean University to share with you some tips on stainless steel tableware.

The easy-to-use stainless steel tableware has the characteristics of collision resistance, acid resistance, heat resistance, etc. The acid value of general food will not corrode the tableware. Therefore, stainless steel tableware can be used to prepare acidic beverages such as lemon juice, as long as you finish it as soon as possible.

However, can stainless steel tableware never get damaged and be regarded as a gifted treasure? Wu Junyi said that under normal use, it is recommended to change the new product after 3 to 4 years of use. If the meal is hit by a major impact or skew, it means that the internal structure has been damaged and gaps have been generated, which will speed up the growth rate of lenses and may cause cracking. Therefore, it is recommended to change the tableware immediately if it has bends, broken snatches, and lenses. If the stainless steel tableware and knives used in the business are sharpened faster, the replacement frequency can be increased to ensure safety.

Use carefully to clean the surface of the varnish for the first time to remove the surface of the varnish. When the varnish is just out of the factory, the surface may still be left with industrial varnish. Therefore, special attention should be paid to the cleaning step for the first time. Wu Junyi suggested that before the first use, first apply salad oil and other edible oils to wipe the surface of the steel tableware, so that the cooking oil and the industrial oil left on the surface can dissolve each other, then wipe the grease with a paper towel, and then clean the grease with a neutral washcoat, and then clean the grease completely with a neutral washcoat, and then start using it. During daily cleaning, use a neutral wash and dry it in a normal dishwashing manner.

When buying stainless steel tableware, how to correctly choose stainless steel tableware when identifying the number "3-opening"? Wu Junyi pointed out that the stainless steel is commonly known as "white wire", which refers to an alloy made by adding additional elements such as lint, lint, lint, and lint into the iron. Adding these metals can reduce the speed of the lens-growing stainless steel, but it does not mean that there will be no lenses at all. Among these elements, the main element that can prolong the lens is "结", and the content of the steel must reach more than 11% to prolong the lens. The stainless steel material has special numbers that are commonly used internationally, mainly 200 series, 300 series, and 400 series. Different series and numbers indicate that the metal components and contents contained in it are different, and the suitable applications are also different. Among them, the 300 series has a sufficient amount of turban content to prolong the growth of lenses, and the material characteristics are also suitable for the production of tableware.

When buying stainless steel tableware, just remember to choose the 304 and 316 materials of "3-opening", and 316 will be more durable than 304. When choosing stainless steel tableware, in addition to looking at the number, it is better to use a slightly thick and a bit thick and heavy feeling when holding it in your hand. Thicker stainless steel tableware will not be damaged or skewed, and it is more durable. When buying stainless steel tableware, you must read the mark carefully. It is recommended to buy products with complete label instructions and clear sources, and use them in accordance with product instructions. Legal stainless steel tableware has strict regulations on the dissolution of heavy metal materials. As long as it is purchased from a legal source, it complies with the regulations of the Food Safety Hygiene Management Law.

Will you get heavy metal if you don’t have stainless steel tableware? Don’t worry about using stainless steel tableware to eat heavy metal? The Food and Drug Administration said that the "food utensil container packaging hygiene standards" have relevant standards for stainless steel tableware orders, and products that meet the standards are less heavy metal dissolution. Therefore, when purchasing, you must choose tableware manufacturers with reliable sources and products that meet the standards. Wu Junyi supplemented it. In the past, the Food and Drug Administration had conducted relevant tests on the content and dissolution of stainless steel tableware in 2012. The dissolution of legal stainless steel tableware is far lower than the intake. In addition, humans will need to take a trace amount of soil every day, and trace amounts of soil will not cause any burden on the body, so there is no need to worry too much.
