Problems solved by technology

However, the core material embedding rate of this type of technology needs to be further improved, and this type of technology mainly uses embedding to protect the core material. Although it is beneficial to avoid the core material from directly contacting the outside world and has a certain protection against contact with oxygen, it does not Consider the performance characteristics of the wall material itself, such as the comprehensive performance of heat insulation, light protection, and oxygen insulation of the wall material, and the protection of the core material that is sensitive to light, heat, and oxygen at the same time is limited.

Abstract

The invention discloses a high-embedding essence microcapsule and a preparation method thereof. The preparation method comprises the steps that maltodextrin and porous starch are mixed; distilled water is added, stirring and mixing are carried out to prepare a mixed solution, a crosslinking agent is added, the pH value of the mixed solution is adjusted to 9-11, stirring is carried out at 30-60 DEGC, the reaction time is 4-24 hours, the pH value of the mixed solution is adjusted to 7-8, and washing, drying, smashing and sieving are carried out to obtain an essence wall material; essence is added into a wall material solution, homogenization is carried out, a uniform emulsion solution is formed, spray drying is carried out, and the essence microcapsule is prepared. The high-embedding essence microcapsule and the preparation method thereof have the advantages that the product is green and environmentally friendly, the cost is low, the essence embedding rate of the microcapsule after adsorption is higher than 85%, and the peroxide value after 12 days of oxidation at 60 DEG C is lower than 0.15-100 grams. The essence embedding method can increase the embedding rate of essence, delay the oxidation of the essence, and is conductive to the storage, transport, application and popularization of the essence.

Description

technical field [0001] The invention relates to the technical field of essence and fragrance treatment, in particular to a high-embedded essence microcapsule and a preparation method thereof. Background technique [0002] Edible flavors refer to aroma substances that have the aroma of natural melons and fruits and can be eaten. Edible flavors can impart aroma to food raw materials, make up for the lack of aroma in food, and improve and optimize the flavor of food. Therefore, it is widely used in modern food industry. According to the sense of olfactory organs, essence can be divided into head fragrance, body fragrance and base fragrance. Water-soluble flavors are made by blending natural flavors and synthetic flavors and dissolving them in aqueous ethanol (or other water-soluble solvents such as propylene glycol). They are mainly used in soft drinks and alcohol. [0003] Common flavors are mostly composed of alcohols, aldehydes, ketones, acids and esters. These substances ...
