Description

Vitamin B 12 microcapsule powder applied to soft sweets and preparation method thereof Technical Field The invention belongs to the technical field of food processing, and particularly relates to vitamin B 12 microcapsule powder applied to soft sweets and a preparation method thereof. Background Vitamin B 12, also known as cobalamin, is a class of cobalt-containing corrinoid complex organic compounds containing trivalent cobalt in the center of the plane of the corrinoid ring, which is the most structurally complex vitamin, and vitamin B 12 is a water-soluble micronutrient essential to the human body and plays a key role in hematopoiesis and in maintaining the health state of the nervous system. The stability of vitamin B 12 is affected by the food processing, storage conditions, the presence of oxidizing and reducing agents, light, acidic or alkaline solutions, and the nature of the food matrix. The water-soluble vitamins are generally poor in stability and are easy to be decomposed by illumination or heating, and the soft sweets are necessarily heated, melted and shaped in the processing process. This means that even water-soluble vitamins can be added to the soft candy and that the activity is not much ensured. Most of the vitamin soft sweets commonly seen in the market can only supplement vitamin C. At present, the prior art discloses that the stability of vitamin B 12 is effectively improved by using improved microencapsulation embedding technology such as maltodextrin, sodium carboxymethyl cellulose, sodium starch octenyl succinate and the like, but the method is applicable to liquid and solid preparations, and the stability of vitamin B 12 in a high-temperature state is not explored. The microencapsulation treatment of vitamin B 12 by adopting the microencapsulation particle technology is also studied, and one or more of the first hydrophobic material mono-diglyceride fatty acid ester and the second hydrophobic material higher saturated fatty acid or carnauba wax are adopted to embed vitamin B 12, so that a good protective effect is achieved, but the problem of degradation of vitamin B 12 in a soft candy dosage form is not solved, and a large amount of saturated fatty acid is adopted in the preparation method, so that the bad influence on the body is caused by long-term eating, strict requirements are also caused on instruments, and the problems of incapability of mass production or low production efficiency are caused. Disclosure of Invention The invention aims to overcome the defects of the prior art and provides vitamin B 12 microcapsule powder applied to soft sweets and a preparation method thereof. In order to achieve the above purpose, the invention adopts the following technical scheme: the vitamin B 12 microcapsule powder applied to the soft sweets is prepared from the following raw materials in parts by weight: 0.8-1.2 parts of vitamin B 12 core material, 4-7 parts of protein, 2.25-4 parts of water-soluble chitosan, 40-45 parts of Arabic gum and 40-50 parts of cyclodextrin; and the mass ratio of the Arabic gum to the water-soluble chitosan is 10 (0.5-1). Preferably, the water-soluble chitosan is chitosan. Preferably, the protein is a soy protein isolate. The application also provides a preparation method of the vitamin B 12 microcapsule powder applied to the soft sweets, which comprises the following steps: S1, fully mixing vitamin B 12 with protein, swelling acacia with water, then adding water-soluble chitosan and cyclodextrin, fully dissolving and dispersing to prepare a wall material solution; s2, adding the mixture of the vitamin B 12 and the protein into the wall material solution, shearing and homogenizing to fully emulsify the solution; S3, spray drying is carried out, and vitamin B 12 microcapsule powder is obtained. Preferably, in the step S1, hot water at 70-80 ℃ is adopted to swell the acacia gum, and in the step S2, the mixture of the vitamin B 12 and the protein is added after the wall material solution is cooled to room temperature. Preferably, after the vitamin B 12 and the protein are added in the step S2, the solid content in the solution is 30-40% by mass percent. Preferably, in the step S2, the shearing homogenization is carried out at a rotation speed of 4000-8000 r/m for 5-10 min. Preferably, in the step S3, the air inlet temperature of spray drying is 160-180 ℃ and the air outlet temperature is 90-100 ℃. Preferably, the spray drying further comprises a step of sieving, wherein the sieving mesh number is 60-100 meshes. The invention uses acacia as main wall material, complex water-soluble chitosan, cyclodextrin as filler, protein as emulsifier and film forming agent, and prepares vitamin B 12 microcapsule by spray drying method. The multi-protection of the protein, the protein-polysaccharide, the mixed wall material and the cyclodextrin is formed outside the vitamin B 12 core material, so that the degradation of the vitamin B 12 in the soft sweet can be effectively dela
