The invention discloses a nutrition regulation and control method based on natural feeding habits of dogs and cats and a matched composition, and belongs to the technical field of pet food. The method comprises the following steps: S1, determining original hunting habits of dogs and cats, and obtaining food types, food sources and food structure data of the dogs and cats in a natural state; s2, based on the original hunting habit data, designing and providing a periodic food composition composed of a plurality of different formulas; s3, feeding different formulas in the periodic food composition in turn according to a predetermined sequence to realize diverse diet; s4, evaluating the influence of the periodic food composition on gastrointestinal health indexes and allergy occurrence probability of dogs and cats through principal component analysis and logistic regression analysis models; and S5, dynamically adjusting the formula or feeding sequence of the periodic food combination according to the evaluation result of the S4. Natural hunting diversity is simulated through periodic food combination, and the problems of nutrition imbalance, intestinal flora imbalance and the like caused by long-term single diet are solved.

The application discloses a Pickering emulsion of deamidated cottonseed protein stabilizing lipase, which is composed of an aqueous phase, an oil phase, a surfactant and a lipase; the oil phase is medium-chain triglyceride, and the volume ratio is 5-10%; the surfactant is deamidated cottonseed protein, and the concentration in the Pickering emulsion is 0.1-10 mg / mL. The preparation method is as follows: the deamidated cottonseed protein is added into deionized water, and is stirred and dissolved on a magnetic stirrer to prepare a uniform aqueous phase dispersion; the medium-chain triglyceride is added into the aqueous phase dispersion, and is subjected to shearing homogenization treatment to obtain a primary emulsion; the lipase liquid is added into the primary emulsion after the homogenization treatment, and is subjected to shearing homogenization emulsification to obtain the Pickering emulsion of deamidated cottonseed protein stabilizing lipase. The application has the advantages of simple preparation process, low requirement on instruments, easy operation and scale-up, green and safe raw materials, and wide application prospect of the prepared Pickering emulsion in the fields of targeted delivery of nutrients, modification of food structure and function, and biological catalytic reaction carrier.

The invention discloses an in-situ resource conversion and food structure generation system for an extreme physical environment, belongs to the technical field of intersection of extreme environmental engineering and food engineering, and aims to solve the problems that food supply depends on external transportation for a long time and the anti-risk capability of a traditional agricultural system is insufficient in the extreme physical environment. The system comprises a resource acquisition module, a resource conversion module, a food structure generation module and a system operation control module. The system generates food base components by obtaining environmental in-situ resources, using biotransformation links, non-biotransformation links, or a combination thereof, and using physical conditions in an extreme environment as processing boundary conditions to perform structured, conformal, or ingestible treatment on the food base components or biological products, such that the food base components or biological products are obtained. And a structured food for human ingestion is generated. The system operation control module dynamically adjusts operation parameters according to a resource state, an energy state or a module operation state, triggers a degradation operation strategy under an abnormal or limited working condition, and preferentially maintains continuous supply of basic food. According to the invention, long-term operation can be realized without external continuous material supply, and the system is suitable for non-earth or non-earth-like extreme physical environments.

The present application relates to packaging food without tempering. The present application discloses a method of manufacturing food, the method comprising providing a mass of food (22), shaping the mass of food into a food structure (26) having a desired shape using a shaping station (20), and applying a packaging material (54) to a surface of the food structure (26) while the food structure remains in contact with a portion of the shaping station (20).

The invention provides a diet recommendation method and device, computer equipment and a storage medium, and belongs to the field of health management, and the method comprises the steps: defining a patient entity, a food entity and a knowledge entity, extracting a medical and nutritional relationship between the entities, defining a knowledge inference rule, and constructing a knowledge graph; designing a double-tower recommendation model, inputting a constraint label generated by reasoning patient structural features and knowledge graph features on the left side, and outputting a patient feature vector; food structural features and attribute tags of the knowledge graph are input on the right side, and food feature vectors are output; calculating a matching score of the patient feature vector and the food feature vector through cosine similarity; a positive and negative sample optimization model is generated by combining a comparison loss function with a knowledge graph; and performing reasoning optimization on the generated initial recommendation list, and outputting a final diet scheme. Thus, the method of fusing professional knowledge and machine learning improves the disjunction problem caused by the fact that a traditional system depends on general rules, and provides more accurate personalized diet guidance.
