Method for preparing starch powdered oil and fat by ultrahigh pressure micro-jet method

Abstract

The invention provides a method for preparing starch powdered oil and fat by an ultrahigh pressure micro-jet method to solve the problems that the conventional process for producing microencapsulated powdered oil and fat is complex, production cost is high, and a large amount of food additives are needed to be added during production. The method comprises the following specific steps of: preparing emulsified liquid by using oil and deionized water, adding starch into the emulsified liquid, stirring and mixing to prepare suspension, performing pregelatinization on starch, cooling, performing ultrahigh pressure micro-jet homogenizing, and spray-drying. The content of the prepared powdered oil and fat and product granularity can be adjusted, the production process is simple and production cost is low, food additives are not used during preparation, and the product has high safety.

Description

technical field [0001] The invention relates to a powdered oil and a preparation method thereof. Background technique As one of the basic components of food, fat plays an extremely important role in food processing and nutrition. It not only provides smooth mouthfeel, good flavor, specific texture and good stability of food, but also increases people's satisfaction with food and makes people feel full. Powdered oil refers to a powder or granular product prepared by scientifically blending, high-pressure homogenization, and spray drying using microencapsulation technology. Compared with the original oil, the microencapsulated powder oil is wrapped by the film formed by the wall material, which can prevent the contact and action of oxygen, heat, light, and chemical substances, and the powder oil can also be used as a source of essential fatty acids and Carrier of fat-soluble vitamins. In addition, oil will also affect the flavor of food, because oil has the ability to de...
