specific Embodiment approach 1

[0027] Specific embodiment one: present embodiment cornstarch-based soybean oil powder grease is prepared according to the following steps: 1, soybean oil and deionized water are prepared into emulsion with high-speed shearing emulsification agitator, the mass ratio of soybean oil and deionized water 1 to 10:200, the speed of the agitator is 7000 to 12000rpm; 2. Take a certain amount of cornstarch and add it to the emulsion made of oil and deionized water to stir and mix to prepare a starch suspension. The mass ratio of oil to starch 5-60:100; 3. Starch pre-gelatinization: put the corn starch suspension in a boiling water bath for 30 minutes, and keep stirring during the gelatinization process, and the stirring speed is 30-200rpm; 4. Cooling: put the pre-gelatinization The gelatinized starch and oil mixture is slowly cooled to 50°C; 5. High-pressure micro-jet homogenization: Add the gelatinized liquid of pre-gelatinized starch and oil to the micro-jet homogenizer for homogeniza...

specific Embodiment approach 2

[0030] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the starch in step one is wheat starch, and the stirring speed is 7000rpm; the gelatinization time of starch in step three is 20min, and the stirring speed in the gelatinization process is 30rpm ; The cooling temperature in step 4 is 40°C; the homogeneous pressure in step 5 is 50MPa; the inlet air temperature in step 6 is 150°C, and the outlet air temperature is 80°C. Other steps and parameters are the same as those in Embodiment 1.

[0031] The embedding rate of the product in this embodiment is 89%, the moisture content is 2.4%, the powder is fine and uniform, the color is milky white, the smell is pure, with the aroma of soybean oil, and no peculiar smell.

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 [0002] 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. [0003] 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 t...
