[0001] This invention relates to the field of cooking technology, and in particular to a method for cooking student meals that improves the safety and taste of dishes. Background Technology

[0002] School meals are a vital dietary source for ensuring the health and growth of students. Their safety, nutritional value, and taste directly impact students' dining experience and overall health. Currently, school canteens and catering companies typically employ conventional cooking methods for large-scale meal provision. While these procedures have certain operational standards, there is still room for improvement in areas such as ingredient quality control, targeted nutritional planning, and refined control of the cooking process. How to systematically develop a comprehensive cooking method from raw materials to finished product that ensures food safety while also catering to the nutritional needs and taste preferences of students of different ages has become a pressing technical challenge in the school meal sector.

[0003] Current student meal cooking methods generally suffer from the following problems: First, in terms of ingredient management, acceptance relies heavily on manual experience, lacking systematic analysis and record-keeping of nutritional components and ingredient quality, making it difficult to ensure high standards and traceability of raw materials; second, recipe design often fails to fully consider the special needs of students' age differences and growth and development stages, and lacks scientific control over food incompatibilities, affecting nutrient absorption and food safety; third, during the cooking process, there is a lack of unified standards for key parameters such as cutting specifications, heat control, and core temperature, leading to inconsistent taste, nutrient loss, or potential food safety hazards; finally, finished product acceptance relies heavily on subjective judgment, lacking quantitative testing of key indicators such as sugar content, salt content, and oil content, making it difficult to achieve standardized output and continuous optimization. Summary of the Invention

[0004] This invention provides a more systematic, scientific, and operable method for cooking student meals, so as to comprehensively improve the food safety and taste experience of the dishes.

[0005] The technical solution adopted in this invention is: a method for cooking student meals to improve the safety and taste of dishes, comprising the following steps:

[0006] S1, Ingredient Acceptance: Establish ingredient acceptance files, conduct quantitative analysis of ingredient quality and nutritional components, including protein, carbohydrates, fat, vitamins, minerals, calcium, iron, zinc, and selenium; staple foods include rice and whole grains to ensure food diversity and nutritional balance; select high-quality ingredients and conduct brand screening for rice, flour, oil, and seasonings; establish acceptance standards for pork including quality, weight, freshness, and lean-to-fat ratio.

[0007] S2, Ingredient Combinations: Based on the student's age, a phased menu is developed every 3 years, with the menu design targeting the critical period of children's bone growth and development; a food incompatibility record is established, and food combinations are selected based on scientific dietary knowledge to avoid incompatible foods;

[0008] S3, Cutting Processing: Set different cutting shapes and sizes for meat products and vegetables according to age groups, and debone and remove tendons from meat products;

[0009] S4, Cooking Control: Controls the ratio of rice to water, the air pressure and temperature of the rice steamer; during cooking, the cooking volume is controlled to be below 60% of the standard capacity of the cooking pot to ensure even stir-frying.

[0010] S5, Cooking Operation: Employs a variety of cooking methods, including stir-frying, quick-cooking, dry-heat cooking, slow-cooking, braising, stewing, boiling, and steam-liquid heat transfer methods, to balance the nutrition, color, and flavor of the dishes.

[0011] S6, Temperature Management: Monitors the center temperature of the dish during cooking to ensure it reaches above 71℃;

[0012] S7, Finished Product Inspection: Quantitatively test the color, taste, sugar content, salt content, and proportion of cooking oil in the finished dishes to ensure they meet the preset standards.

[0013] As a further improvement of the present invention, in step S1, the nutritional component analysis includes using a testing device to quickly test the ingredients and recording the test data into the ingredients acceptance file.

[0014] As a further improvement of the present invention, in step S2, the food incompatibility profile includes a database of common food incompatibility combinations, and uses software tools to assist in recipe design to achieve scientific pairing.

[0015] As a further improvement of the present invention, in step S3, the cutting standard includes specifications for the size and shape of the cut pieces for different age groups, in order to adapt to the chewing and digestive abilities of students.

[0016] As a further improvement of the present invention, in step S4, the ratio of rice to water is 1:1.2-1.5, the steam pressure of the rice steamer is 0.1-0.15MPa, and the temperature is 100℃-120℃.

[0017] As a further improvement of the present invention, in step S5, the cooking method is selected according to the characteristics of the ingredients, and the heat control includes stir-frying over high heat and simmering over low heat, so as to retain nutrients and improve the taste.

[0018] As a further improvement of the present invention, in step S6, a temperature probe is used to monitor the center temperature of the dish in real time and record the temperature data to ensure food safety.

[0019] As a further improvement of the present invention, in step S7, the finished product inspection uses sensors and instruments to measure sugar content, salt content and edible oil content, and compares them with preset thresholds to automatically determine whether it is qualified.

[0020] The beneficial effects of this invention are as follows: By establishing ingredient acceptance records, implementing quantitative analysis of nutritional components, and developing age-appropriate recipes and food incompatibility records, this invention achieves systematic management from raw materials to the table. This method overcomes the limitations of traditional reliance on manual experience, ensuring high-quality ingredients and nutritional balance through data-driven and standardized operating procedures, while scientifically mitigating dietary risks, making the nutritional supply of student meals more precise and safer.

[0021] This invention sets clear operational standards and parameter ranges for key aspects such as cutting specifications, cooking volume, heat control, heat transfer methods, and core temperature. For example, by controlling the cooking volume to below 60% of the pot capacity to ensure even heating, and by flexibly applying various cooking methods, the core temperature is required to reach above 71°C. These refined control measures not only thoroughly kill pathogenic microorganisms and ensure food safety, but also minimize nutrient loss and promote better color, shape, and flavor in the dishes, significantly improving the overall sensory quality and acceptance of student meals.

[0022] Unlike traditional methods that rely on subjective sensory evaluation, this invention introduces instrumental testing and threshold comparison of key indicators such as color, sugar content, saltiness, and the proportion of edible oil in the final product inspection stage. This innovation shifts product quality assessment from "subjective experience" to "objective data," ensuring not only the consistency, stability, and health of the products, but also providing reliable data support and optimization directions for continuous improvement of production processes. Ultimately, this drives the entire student catering industry towards a higher level of standardization and scientific development. Detailed Implementation
