The spicy essential oil is dark red, has the combined fragrance and spicy flavor of the pepper and the hot pepper, can help to promote the appetite of a human body, and also ensures that the food has better quality. In addition, because of the abundant bioactive substances, the spicy and hot essential oil also has the physiological activities of resisting bacteria, diminishing inflammation, resisting oxidation, easing pain, improving the digestive system and the like.
However, the spicy essential oil is highly volatile and poorly water-soluble, and the flavor and active substances therein are easily oxidized and degraded by light, heat and oxygen during processing, thus limiting its wide application in the food industry. The microcapsule technology is a technology of wrapping a target (core material) in a natural or synthetic polymer compound continuous film (wall material), and has good protection, barrier property and slow release property for the target. In addition, the hydrophilic wall material is selected to enhance the solubility of the spicy essential oil in water. The sodium starch octenyl succinate is special edible modified starch, has superior film forming property, emulsifying property and stability, and is a microcapsule wall material with wide sources and practicability. As the technology of microencapsulation has matured, different materials have been used for microencapsulation of spice essential oils.

The invention uses spice oleoresin as a core material, a mixture of soybean protein and maltodextrin as a wall material, sucrose fatty acid ester and Tween 80 as emulsifying agents, and adopts an emulsion embedding spray drying method to prepare the essential oleoresin microcapsule. The invention has reliable process, soft and round product color and taste, high utilization rate of raw materials and lower energy consumption. Is suitable for refining natural spice seasonings such as zanthoxylum oil, capsicum oil, garlic oil and the like into powdery or granular seasonings which are convenient to use, store and transport. The invention takes the sodium starch octenyl succinate-resveratrol compound as the emulsifier, and does not add the emulsifier additionally, thereby saving the production cost, and avoiding the safety problem and the product storage caking problem caused by adding the emulsifier.
Patent CN103054030a discloses a method for preparing perilla oil powder by microencapsulation. The perilla oil powder is prepared by taking perilla oil as a core material, pasting starch octenyl succinate as a wall material, stirring and emulsifying at a high temperature, and then spray drying. The invention has the advantages of no need of adding emulsifying agent, simple operation process and good water solubility, dispersibility and stability of perilla oil powder. Furthermore, the starch octenyl succinate has low price, and can reduce the cost of products. However, the wall material is single octenyl succinic acid starch ester, and can not provide enough protection for unstable perilla oil to resist high temperature and oxidization in the spray drying process.
Patent CN112869050B discloses a preparation method of a pepper essential oil microcapsule and application thereof in frying food.

Compared with comparative example 1, 6.4g of spicy essential oil microcapsules are respectively added into the crust and the stuffing according to the proportion of 3:2, and special flavor elements are introduced. The prepared spicy moon cake has clear pattern and full appearance, and has no obvious phenomena of waist swelling, sinking, cracking, collapse, stuffing exposure and the like; the moon cake is light brown, the surface is bright, the bottom is not burnt, the thickness of the moon cake skin is uniform, the stuffing is uniformly mixed, and the peeling is avoided; the spicy flavor can be rapidly perceived, the pepper flavor is fresh and upward, the spicy and numb feeling is strong, the burnt bitter taste is not perceived, the flavor harmony is optimal, and the sensory score is 91.0 (table 3). The good heat resistance of the microcapsule wall material protects the hydroxy-alpha-sanshool from heat and oxygen, and improves the retention rate to 90.34% (figure 1).
As shown in table 4, the embedding rate and the loading rate of the spicy essential oil microcapsule are in an increasing trend with the increase of the concentration ratio of sodium starch octenyl succinate to resveratrol, which is probably because the incorporation of resveratrol effectively improves the oil-water interfacial capacity of sodium starch octenyl succinate, and can emulsify and embed spicy essential oil to a greater extent, thereby improving the embedding rate and the loading rate. Meanwhile, the coating effect of the resveratrol and the non-covalent combination of the sodium starch octenyl succinate and the resveratrol jointly resist damage caused by spray drying, and the stability of the spicy essential oil microcapsule is improved. The obvious reduction of the particle size indicates that the microcapsule has better effect and better solubility. However, as the incorporation amount of resveratrol increases, there is a significant difference in hygroscopicity of microcapsules. When the concentration ratio of starch sodium octenyl succinate to resveratrol is 10:5, the hygroscopicity of the microcapsules exceeds that of the powder with low hygroscopicity (< 15g/100 g). In summary, the spicy essential oil microcapsule with the concentration ratio of the sodium starch octenyl succinate to the resveratrol of 10:3 has ideal embedding rate, loading rate, particle size and hygroscopicity.
