Fast food udon is born to cater to the taste and needs of the public. It is fast to serve and has a smooth and chewy texture. In order for everyone to enjoy such delicious food. Solving the problem of spoilage and deterioration caused by microbial spread during storage and transportation has become a key issue for product quality. The key to product quality lies in the production process, which includes steaming, acidification, sealed packaging, and sterilization.
Firstly, the product is steamed and matured to fully gelatinize the starch in the raw noodles. At the same time, the protein in the raw noodles undergoes denaturation when heated, causing the raw noodles to change from raw to cooked. The general cooking time for noodles is about 3.5 minutes, and the temperature of the steamer should reach 96-98 ° C. The moisture content should be over 60%, and the water activity is also high, making it easy for microorganisms to grow.
Next, the steamed noodles will be washed in an acid pickling tank with a pH of around 4.3 that has undergone purification treatment for about 50 seconds. The purpose of water washing and acid washing is to quickly cool the hot noodles, make their surface converge, prevent further gelatinization, prevent the noodles from sticking to each other, and have antibacterial effects. The pH value of noodles is between 3.8-4.2, which is beneficial for ensuring sterilization effect in a short period of time below 100 ℃.
After the noodles are sealed in the packaging bag, they are sterilized. The packaged noodles are sterilized by steam heating at a temperature of 92-95 ° C for about 35 minutes. Ensure that the noodles reach commercial sterility and are no longer contaminated by external factors.
