However, due to the great role of essence in human life, as early as 1932, Britain began to develop essence microcapsules using Arabic gum [1]. Until now, people's research on microcapsule essence is still in the ascendant, and related literature reports and patent applications emerge one after another. The core material of microcapsule essence is essence, and the industrial production of microcapsule edible essence began in1960s, with floral essence such as rose, jasmine and orchid, fruity essence such as lemon, orange, strawberry, banana, grape, cherry and apple, and essential oil or resin such as garlic oil, ginger oil, mustard oil and mint oil as the core materials. In addition, additives can be added to the core material to control the release rate of flavor molecules. It can be mixed with additives and packaged, or it can be packaged step by step, depending on the specific situation. The wall material of essence and fragrance microcapsules may depend on the core material. The general requirements are that the materials are stable in performance, non-toxic and side effects, incompatible, and will not affect the functions of flavors and fragrances. They must have satisfactory viscosity, permeability, strength and plasticity. The wall materials commonly used in essence microcapsule technology are plant gum (Arabic gum, sodium alginate, carrageenan, etc. ), starch and its derivatives (various dextrins, oligosaccharides, starch derivatives, etc. Protein (gelatin, casein, soybean protein, whey protein, etc.) has good emulsifying property, film-forming property and compact quality, and is a good wall material for embedding essence. ), and various cellulose derivatives (CMC). The research and development of new wall materials has always been an important topic. If modified starch with excellent properties is obtained after necessary modification of starch [2~3], the solubility of chitosan can be obviously improved by controlling the deacetylation degree of chitosan [4]; Maillard products obtained by the reaction of protein raw materials with carbohydrates can also be good embedding raw materials [5]; It is also a meaningful research direction to synthesize high-quality embedding materials by mutagenesis or domestication of specific microbial species. In practical application, microencapsulation can rarely be achieved with only one wall material, but it is often the combination of two or more wall materials to achieve the required embedding effect. After the essence is microencapsulated, due to the sealing effect of the capsule wall, the evaporation loss of essence can be effectively suppressed, and the stability of essence storage and use can be improved; Can protect sensitive ingredients, greatly improve the oxygen resistance, light resistance and heat resistance, and increase its stability in baked food and puffed food; The essence can have a slow release function; Can avoid the reaction between essence components and other components; It can change the physical form of essence at room temperature, transform liquid or semi-solid essence into free-flowing powder, and improve dispersion stability. The technical product using "microcapsule flavor and fragrance finishing agent" is a nano-capsule product that wraps industrial flavors, plant essential oils and other raw materials with special materials and scientific methods through modern scientific and technological means. This technology adopts the principle of slow release, uses the fragrance finishing agent of microcapsule essence, and adds it to textiles or paper products through post-finishing, which can keep the fragrance for more than 12 months. This product can also be used in plastic rubber, leather products, chemical coatings, paint inks and other industries. Packaging storage packaging: 25KG/ barrel, stored in a cool and dry place, storage period 12 months.
