Description

Preparation method of high-strength Wen Chongwu-resistant synthetic roe Technical Field The application relates to the technical field of pet foods, in particular to a preparation method of a synthetic roe for resisting high Wen Chongwu. Background With the popularization of the concept of fine feeding of pets, nutrition supplementation of dogs, cats and other pets is increasingly important. The key nutrient substances such as fish oil, krill oil, taurine and the like become important functional additive components in the pet food because of the health promotion effect of the key nutrient substances on the skin, hair, cardiovascular, vision and nervous system of the pet. At present, two main technical paths exist for supplementing the nutrient substances, namely, one is a direct adding method, namely, fish oil, taurine and the like are directly mixed in the wet food matrixes of pets such as cat food, cans, cat strips or hair melting cream and the like. Although the method is simple in process, the method has obvious limitations, namely, partial nutrient substances (such as unsaturated fatty acid) are easy to oxidize and deteriorate, the stability is poor, certain components have unpleasant fishy smell or peculiar smell of pets, the overall palatability of the product is affected, and the targeted or controlled release delivery of the nutrient substances cannot be realized. The other is embedding and adding method, namely coating the nutrient substances by microencapsulation and other technologies, and then mixing the nutrient substances into the food. The method can effectively isolate oxygen from illumination, improve the stability of nutrient substances, mask bad flavor, and realize slow release or fixed point release by design. In recent years, a 'pet crystal ball' imitating the morphology of fish becomes a market hotspot, and the 'pet crystal ball' embeds nutrient substances in the tiny gel ball, has novel appearance and improves the feeding experience of pets. Most of the existing pet crystal balls are solid gel balls, and the microstructure of the existing pet crystal balls is essentially different from the sac cavity structure (namely, the inside of the existing pet crystal balls is provided with a liquid cavity or a core-shell structure) of the natural roe. The application number is that the patent discloses a microcapsule preparation method taking curdlan and sodium alginate as wall materials and loading lutein, the obtained product is solid gel particles, and the particle size distribution is uniform, so that the active material loading amount per unit volume is low. In addition, pet food wet products are often subjected to severe high temperature sterilization (e.g., 121 ℃ C., maintained for 1-2 hours) to ensure commercial sterility and extended shelf life, requiring the addition of functional particles, including synthetic roes, to have excellent heat stability, to remain structurally intact, to not crack, to not melt, to not leak, and to not significantly degrade or otherwise lose core nutrients. Aiming at the related technology, the field of nutrition supplement for pets is in need of developing a novel high-temperature resistant synthetic roe which can simulate the sac cavity structure of the natural roe to realize better active substance loading rate and meet the high-temperature sterilization process of wet food for pets. Disclosure of Invention In order to achieve the uniform-sized sealed sac cavity morphological structure of the real roe, and simultaneously meet the 121 ℃ sterilization condition of the pet food and the aim of improving the nutrient loading capacity, the application provides a preparation method of the synthetic roe for resisting the high Wen Chongwu.
