Description

Embedding agent, application thereof and miso powder containing embedding agent Technical Field The invention belongs to the technical field of food engineering, and particularly relates to an embedding agent and application thereof. Background The embedding technology mainly uses a polymer encapsulating material to coat solid, liquid or gas micro-capsule core materials to form micro-capsules with the diameter of 1-5000 microns. The embedding technology is mainly used in the food field for protecting sensitive components, controlling release, masking bad flavors and converting liquid components into solid powder which is easy to process, thereby protecting, controlling release and improving the functionalization of food active components. The traditional embedding agent comprises modified starch, trehalose, sodium carboxymethyl cellulose, polyvinylpyrrolidone and the like, but for the synthetic embedding agent, the non-fully reacted modified agent, monomer, catalyst, plasticizer or other additives may be contained, the substances may migrate into food from wall materials to bring health hidden danger, for the embedding agent such as maltodextrin and the like, the film forming property and the protection property are poor, oxygen, moisture and light can still slowly permeate, so that core materials (such as omega-3, probiotics and essence) are gradually degraded, oxidized or lose efficacy, in addition, part of the embedding agent is sensitive to conditions such as pH value, temperature, shearing force and the like in the food processing process, the modified starch such as oxidized starch and the like cannot be used for food processing, the self flavor is obvious, the quality of the product is easily changed after embedding, the impure peculiar smell such as astringent taste, sour taste or metallic taste is brought, the original aroma of the product is covered, the consumer acceptance is reduced, and in addition, the method is not widely used due to the fact that the raw material sources, the process and the like are complicated for Arabic gum, the octenyl succinic acid starch ester and the like. Thus, there is a need in the art for an embedding agent that is safe in source, good in film forming and carrier properties, and can be used in the food field, and which is expected to be odorless and does not impart significant flavor changes to the substrate. Disclosure of Invention In view of the shortcomings of the prior art, one of the purposes of the present invention is to provide an embedding agent, which is prepared by the following method: (1) Taking rice as a raw material, crushing the rice, adding medium-temperature amylase into the crushed rice for enzymolysis, wherein the viscosity of the material after enzymolysis is less than or equal to 100BU, and the sugar content is 20-28%; (2) Filtering the material after enzymolysis to obtain filtrate with particle diameter less than or equal to 125 μm and viscosity less than or equal to 85 BU; (3) Homogenizing the filtrate until the fineness is less than or equal to 100 mu m to obtain a homogenized solution, namely a dispersion solution in which the embedding agent is dispersed. According to the application, low-allergic rice is taken as a raw material, and is subjected to moderate enzymolysis after being crushed, so that on one hand, the flexibility and flexibility of molecular chains of the rice raw material are preserved, and meanwhile, the proper molecular chain length is reserved, so that long-chain hydrophobic groups can adaptively move, wind or rearrange in the embedding process due to hydrophobic action, so that the surface of a material to be embedded can be formed into a film, on the other hand, the molecular chain is provided with a proper amount of hydrophilic groups such as hydroxyl groups, carboxyl groups and/or amino functional groups through moderate enzymolysis, the dispersibility in an embedding solution is improved, the mixing and dispersion with the material to be embedded are facilitated, and meanwhile, more hydrogen bonds are brought to the material to be embedded, so that the strength and stability of the wall material to be embedded are improved. The embedding agent disclosed by the application is derived from rice, can provide good film forming property and stability through proper enzymolysis and homogenization treatment, and belongs to clean, natural, safe and healthy food raw materials. Furthermore, rice belongs to a hypoallergenic food, which widens the application scenarios of the embedding agent. Meanwhile, the rice has light flavor, no peculiar smell is introduced after enzymolysis, and the functionality or the flavor of the material to be embedded is not covered or influenced. The embedding agent provided by the application has proper hydrophilic groups on the outer layer of the embedded product, so that the embedding agent can be quickly dissolved in water, and the dissolved solution has high clarity, so that the application of
