[0002] Pre-prepared dishes refer to finished or semi-finished dishes that have undergone preliminary processing such as washing, cutting, and seasoning, or have been fully cooked, and are then preserved by methods such as quick freezing or refrigeration. Common types include ready-to-eat foods, instant-heat foods, and ready-to-cook foods. They are characterized by convenience, speed, and variety, but some products may have controversies regarding the use of additives and the retention of nutrients. They are mainly used in daily family meals, standardized meal preparation in restaurants, and takeout fast food scenarios. In recent years, market demand has grown rapidly due to the fast pace of life.

[0003] The pre-prepared food processing mainly follows a standardized process. First, fresh raw materials are pre-treated by washing, removing impurities, and cutting. Then, depending on the type of dish, they are seasoned, marinated, or cooked, such as stir-frying, steaming, or deep-frying. Afterward, they are quickly cooled to a safe temperature to prevent the growth of microorganisms. They are then sealed using vacuum packaging or nitrogen-filled packaging. Finally, they are stored through high-temperature sterilization, quick-freezing, or refrigeration to facilitate transportation and sales.
