NSF's evaluation program for food-grade lubricants has been widely recognized internationally, and the "Certification of Lubricants in Incidental Contact with Food" is referred to as "Local Certification of Food-Grade Lubricants", which is filed with the China National Certification and Accreditation Commission to certify food lubricant companies and products in China. The standard adopts the Chinese "food grade lubricant" certification mark, which meets the requirements of government supervision and is conducive to the identification of users such as food production enterprises. The certification standard ensures that the quality of the product from formula design, production process, storage and transportation process to the end product can be consistent through formula evaluation, product testing, factory audit, blockchain traceability and other technologies. The certified products are traced back to achieve the effect of product screening and certificate verification.
