Embodiment 1

[0016] 1) Dry and pulverize the star anise, steam distill it for 3 hours under the microwave power of 150W, and collect the colorless and transparent star anise volatile oil as the heartwood for later use;

[0017] 2) Weigh Arabic gum and maltodextrin at a weight ratio of 1:2, add water 1.5 times the total weight of the material to dissolve, and obtain a wall material solution;

[0018] 3) Mix the above-mentioned heartwood with the wall material solution to obtain a dispersion, the heartwood accounts for 10% of the dry matter weight of the wall material solution;

[0019] 4) Add 0.5% of the weight of the mixed emulsifier of monoglyceride and sucrose ester (monoglyceride: sucrose ester = 1:1) to the dispersion, mix well, and emulsify at 60°C and 15MPa. The air temperature is 150°C, the outlet air temperature is 80°C, and the atomization pressure is 0.2MPa, and it is spray-dried to obtain the product.

Embodiment 2

[0021] 1) Dry and pulverize the star anise, steam distill it for 5 hours under the condition of microwave power of 200W, and collect the colorless and transparent star anise volatile oil as the heartwood for later use;

[0022] 2) Weigh Arabic gum and maltodextrin at a weight ratio of 1:10, add water twice the total weight of the material to dissolve, and obtain a wall material solution;

[0023] 3) Mix the above-mentioned heartwood with the wall material solution to obtain a dispersion, and the heartwood accounts for 30% of the dry matter weight of the wall material solution;

[0024] 4) Add 2% of the weight of the mixed emulsifier of monoglyceride and sucrose ester (monoglyceride: sucrose ester = 1:10) to the dispersion, mix well, and emulsify at 80°C and 40MPa. The air temperature is 200°C, the outlet air temperature is 110°C, and the atomization pressure is 0.5MPa, and spray drying is carried out to obtain the product.

Embodiment 3

[0026] 1) Dry and pulverize the star anise, steam distill it for 4 hours under the condition of microwave power of 180W, and collect the colorless and transparent star anise volatile oil as the heartwood for later use;

[0027] 2) Weigh Arabic gum and maltodextrin at a weight ratio of 1:8, add 1.8 times the total weight of the material to dissolve in water, and obtain a wall material solution;

[0028] 3) Mix the above-mentioned heartwood with the wall material solution to obtain a dispersion, and the heartwood accounts for 20% of the dry matter weight of the wall material solution;

[0029] 4) Add 1.5% of the weight of the mixed emulsifier of monoglyceride and sucrose ester (monoglyceride: sucrose ester = 1:2) to the dispersion, mix well, and emulsify at 70°C and 25MPa. The air temperature is 190°C, the outlet air temperature is 110°C, and the atomization pressure is 0.4MPa, and spray drying is carried out to obtain the product.

Abstract

The invention provides a preparation method of anise volatile oil microcapsules. The method comprises the following steps of: firstly, preparing anise volatile oil; then, preparing a wall material liquid based on Arabic gum and maltodextrin as raw materials, then, adding a mixed emulsifier of monostearin and sucrose ester to obtain lactescence; and mixing the lactescence with heartwood, emulsifying, and spraying and drying to obtain microcapsule particles. The method is simple and accessible. The microcapsule particles prepared are round, uniform in size and full of anise fragrance. The content of the anise volatile oil in each microcapsule is 40-95mg / g, the microencapsulation efficiency is over 95%, and the product has good thermal stability and dissolving dispersion and can be widely applied to the field of foods, daily use chemicals and medicines.

Description

technical field [0001] The invention belongs to the technical field of food processing, and mainly relates to a preparation method of star anise volatile oil microcapsules. Background technique [0002] Star anise, also known as star anise, is the fruit of Magnoliaceae plant Illicium verum Hook.f. Because of the peculiar shape of the fruit, which is gear-shaped, each consists of seven to nine pods, most of which are eight, hence the name "octagonal". Star anise is warm and pungent in nature and has aroma. In addition to being used as a spice, it is also an anti-inflammatory and analgesic traditional Chinese medicine. It has the functions of warming yang and dispelling cold, regulating qi and relieving pain. , the effect of waist and abdomen distension and pain. Star anise is rich in volatile oil, which can be used as flavoring agent and fragrance in the food industry, and can also be used as a masking agent in soap, mouthwash, toothpaste and other daily necessities industr...
