Qiaojian stainless steel kitchen utensils


There are all kinds of stainless steel kitchen utensils sold in the market. How to identify and find safe and suitable ones? In addition to the brand, appearance, and feel, it is most important to check the labeling of the product.

First of all, you should have an understanding of the materials used in such products. Such products currently on the market commonly include stainless steel knives, forks, spoons, bowls, pots, filters in food processing utensils, inner pots, etc. If classified according to stainless steel material, it can be generally divided into four categories according to the organizational structure: austenitic stainless steel, ferritic stainless steel, austenitic-ferritic stainless steel and martensitic stainless steel. The corrosion resistance and hygienic safety performance of each material Also different. Generally, according to the structure, it can be divided into four types: austenitic stainless steel, ferritic stainless steel, austenitic-ferritic stainless steel and martensitic stainless steel. The corrosion resistance and hygienic safety performance of each material are different. From the characteristics of these four types of stainless steel, martensitic stainless steel has higher strength and hardness than the other three types, but its corrosion resistance is significantly lower than that of the other three types. According to the national standard, martensitic stainless steel can be used for tableware and food processing and research utensils, and products such as stainless steel containers should be produced from the other three types of stainless steel. This means that austenitic stainless steel should be selected for various food storage containers and food processing machinery. For all kinds of tableware, martensitic stainless steel should be used.

Secondly, we must carefully observe the outer packaging of the product and various certificates and certificate numbers. First, pay attention to whether the physical object is consistent with the content described on the package; second, check whether the product has the product quality certificate, the production license and license number marked by QS, and the certificate number issued by GB or other national certification departments; Whether there is a Chinese product name, manufacturer name and address on the product; Fourth, whether the product specification, grade, main ingredient name and content, etc. are marked on the packaging or manual; Fifth, whether there are some correct operating specifications or cleaning methods on the packaging or manual Sixth, due to improper use, products that are likely to cause damage to the product itself or may endanger personal and property safety should have warning signs or Chinese warning instructions. my country's "National Food Safety Standard for Stainless Steel Products" GB9684-2011 also gives more specific marking requirements for stainless steel kitchen utensils, that is, "food contact use" should be marked on the product or the minimum sales package; Identifies the stainless steel type.

Finally, some labels will directly mark the stainless steel model, which can also be used as a basis for judging the quality of the product. Generally speaking, the model of stainless steel products with higher price and better quality is 304, relatively speaking, the 202 series is worse
