It is generally admitted that the expression ‘traditional food’ refers to a product with specific raw materials, and/or with a recipe known for a long time, and/or with a specific process. China has a wealth of traditional foods such as Chinese steamed bread, Chinese noodles, Chinese rice noodles, Starch noodles (Vermicelli), Tofu, Sofu (soybean cheese), douchi (fermentation soybean), Chinese vinegar and many other foods. These traditional foods are an important component of Chinese people’s diet and the basis for their food habits and nutrition.
