Phacoemulsification refers to the process of mixing two (or more than two) immiscible solutions uniformly to form a dispersion system under the action of ultrasonic energy, in which one liquid is evenly distributed in the other liquid to form an emulsion. Compared with general emulsification technology and equipment (such as propeller, colloid mill, homogenizer, etc.), ultrasonic emulsification has the characteristics of high emulsification quality, stable emulsification, stable emulsified product and low power required.
Phacoemulsification has been applied in many fields, and it plays a unique role in each field.
There are many industrialized phacoemulsification applications, and phacoemulsification is one of the earliest technologies used in food processing by ultrasound. For example, soft drinks, ketchup, mayonnaise, jam, artificial milk, baby food, chocolate, salad oil, oily sugar water and other mixed foods used in the food industry have been tested and adopted at home and abroad, and improved The effect of product quality and production efficiency, and the aqueous carotene emulsification has been successfully tested and used in production.
Using the physical modification method of ultrasonic dispersion combined with high pressure cooking to pre-treat the banana peel powder, and then use amylase to hydrolyze the banana peel powder. A single factor experiment was used to study the effect of this pretreatment method on the extraction rate of soluble dietary fiber in banana peels and the physicochemical properties of insoluble dietary fiber in banana peels. The results show that ultrasonic dispersion combined with high-pressure cooking is compared to simple treatment without pretreatment. The insoluble dietary fiber obtained by enzyme treatment increased the water holding capacity by 5.05g/g, the combined water capacity by 4.66g/g, the oil holding capacity by 4.60g/g, and the swelling capacity by 0.4mL/g.
In the pharmaceutical industry and daily necessities industry, phacoemulsification is often used in the manufacture of various emulsion products, such as emulsion medicines, cosmetics and shoe polish. Ultrasonic emulsification method can also be used to make emulsified combustion products of oil (gasoline, diesel, etc.) and water or pulverized coal to increase the combustion value of unit fuel.
