Stainless Steel Tableware - Safety Standards & Daily Use

Q1: What are the safety requirements for stainless steel tableware? A1: Stainless steel tableware must meet the food safety standards of the target market (such as FDA in the US, EU 10/2011, GB 4806.9 in China), with the following core requirements: 1. The migration of harmful elements (lead, chromium, nickel) must be within the limit (lead ≤0.01 mg/dm², chromium ≤0.4 mg/dm²); 2. The surface must be smooth, no burrs, scratches or rust spots, to avoid contaminating food; 3. The material must have good corrosion resistance, no rust or deformation during use; 4. The welding seam must be firm and smooth, no gaps or slag.

Q2: Which grades of stainless steel are suitable for stainless steel tableware? A2: The most suitable grades are 304 and 316. 304 stainless steel tableware is suitable for daily use (such as home tableware), with good corrosion resistance and hygiene, meeting general food safety requirements. 316 stainless steel tableware has better corrosion resistance to acidic and salt-containing foods (such as pickles, seafood), and is suitable for high-end catering (such as hotels, restaurants) and baby tableware. It is not recommended to use 201 or 430 stainless steel for tableware in direct contact with food for a long time.

Q3: How to select safe and high-quality stainless steel tableware? A3: Selection methods: 1. Check the marking: the product should be marked with "food contact", material grade (304/316) and standard number (such as FDA, GB 4806.9); 2. Observe the surface: the surface should be smooth, bright, no burrs, scratches or rust spots, and the welding seam should be firm and smooth; 3. Check the weight: high-quality stainless steel tableware has a moderate weight, not too light (thin material) or too heavy (uncomfortable to use); 4. Smell the odor: there should be no peculiar smell, indicating no harmful substances; 5. Ask for certification: ask the supplier to provide a food safety test report.

Q4: Can stainless steel tableware be used in microwave ovens or induction cookers? A4: For microwave ovens: No, stainless steel is a metal material that will reflect microwave energy, which may cause sparks, damage the microwave oven and even cause safety hazards. For induction cookers: Yes, most stainless steel tableware (with ferromagnetic properties, such as 430, 304 with weak magnetism) is suitable for induction cookers. When purchasing, you can check whether the product is marked "induction cooker compatible" or test it with a magnet (if it is magnetic, it is suitable).

Q5: What are the taboos in using stainless steel tableware? A5: Taboos: 1. Do not store acidic or salt-containing foods (such as tomato sauce, pickles, soy sauce) for a long time, as they will corrode the surface passive film and cause the migration of harmful elements; 2. Do not use strong acid/alkali cleaners (such as bleach, vinegar) for long-term soaking or cleaning; 3. Do not use abrasive cleaners (such as steel wool) or hard objects to scratch the surface; 4. Do not heat empty stainless steel tableware on high fire for a long time (it will cause deformation and damage the material); 5. Do not mix with other metal tableware (to avoid electrochemical corrosion).
