Problems solved by technology

Sucrose is easy to dissolve and easy to operate, and the solution has the characteristics of high concentration and low viscosity, so it is a better wall material for microcapsule embedding, but sucrose does not have emulsifying properties and can only be used as a filling material in the wall material. Emulsifying protein, modified starch or small molecule emulsifier and other substances are compounded and used for embedding

Embodiment 1

[0019] At 55°C, mix and dissolve 9.3% (w / v) food-grade modified starch and 18.6% (w / v) sucrose with distilled water, and add 12% (w / v) melted palm kernel oil to make milk liquid; under the condition of 65°C, the high-speed shearing machine shears and emulsifies at 8000rpm, and shears for 3min; the sheared emulsion is immediately subjected to high-pressure homogenization with a high-pressure homogenizer, and the homogenization pressure is 35Mpa, and the homogenization is performed twice; The homogenized emulsion is spray-dried, the air inlet temperature is 195° C., and the air outlet temperature is 90° C. to obtain the finished palm kernel oil powder oil.

[0020] The food-grade modified starch used is a food-grade esterified modified starch prepared by reacting starch with octenyl succinic anhydride OSA. The food-grade modified starch product used in the present invention is provided by National Starch Shanghai Company.

Abstract

A making method of powdered palm kernel oil belongs to the technical field of oil microencapsulation and includes using food-grade modified starch and cane sugar as shell material for microencapsulation and embedding of refined palm kernel oil. Only the macromolecular food-grade modified starch and the cane sugar are used as the shell material, no small molecular emulsifier is added, and the obtained powdered palm kernel oil has embedding rate up to 98.79% and is microencapsulated powdered oil with no additive and fine embedding effect. Natural refined palm kernel oil is used as core material for the powdered palm kernel oil, and accordingly hazards to human health caused by the use of hydrogenated vegetable oil as the core material are avoided. The powdered palm kernel oil has certain fluidity and dispersibility and is easy to dissolve in hot water and applicable to various foods, and reconstituted milk of the powdered palm kernel oil has fine emulsion sensory properties. Preparation of the powdered oil makes industrial oil processing convenient and makes the oil convenient to transport and store, and accordingly application and usage range of the oil is widened greatly.

Description

technical field [0001] The invention relates to a method for preparing powdered oil, in particular to a method for preparing palm kernel oil powdered oil without small molecule emulsifiers and having simple wall materials, and belongs to the technical field of oil microencapsulation. Background technique [0002] Compared with the original oil, the characteristics and processing performance of the microencapsulated powdered oil are greatly improved. Powdered oil is less affected by temperature, has good fluidity and storage stability, and is easy to mix with other powdery raw materials, which provides convenience for industrial processing of oil, and is convenient for transportation and storage. Powdered oil has strong solubility in water and emulsifying and dispersing ability, which improves the dispersibility of oil, and can be used in foods that have always been unable to use oil or are difficult to use oil. After the oil is embedded in the wall material, it avoids conta...
