High-quality coconut-oil microencapsulated powder grease and high-efficiency preparation method thereof

Abstract

The invention discloses high-quality coconut-oil microencapsulated powder grease and a high-efficiency preparation method thereof. The preparation method of the high-quality coconut-oil microencapsulated powder grease comprises the following steps of treating a wall material solution by adopting combination of an ultrasonic device, a heater, a controllable stirring device and a vacuuming device; treating a mixed solution of a wall material and a core material by adopting combination of high-speed shearing and an injector; upper-layer foam in coarse emulsion is removed by connected a reducing hole-type defoaming paddle and a stirrer; and high-pressure homogenization treatment and spray-drying are performed so as to obtain a powder grease product. According to the preparation method of the high-quality coconut-oil microencapsulated powder grease, dissolution rate and sterilization effect of the wall material solution are improved by utilizing high temperature and stirring effects; and the high-speed shearing process and the injection method are combined so as to efficiently remove foam by adopting the ultrasonic device, the vacuuming device and the reducing hole-type defoaming paddle. And thus, the prepared high-quality coconut-oil microencapsulated powder grease is stable and uniform in particle size. The high-quality coconut-oil microencapsulated powder grease prepared by adopting the method has the characteristics of high yield, high encapsulation rate, high storage stability and high anti-oxidation capability; and thus, the high-quality coconut-oil microencapsulated powder grease is suitable for the fields of instant foods, health foods, baked foods and the like.

Description

technical field [0001] The invention relates to a microencapsulated powdered oil and a preparation method thereof, in particular to a high-quality coconut oil microencapsulated powdered oil and a high-efficiency preparation method thereof. Background technique [0002] Edible coconut oil is white or light yellow. It is the only oil composed of medium-chain fatty acids in daily food. It is easily digested and absorbed by the human body and improves the efficiency of metabolism. Because it is solid at normal temperature, has poor fluidity and is easy to oxidize and deteriorate, it brings inconvenience to food processing. Powdering coconut oil microcapsules can increase the added value of coconut oil. [0003] Powdered oil is a powder product formed by embedding oil with wall materials using microcapsule technology. Microcapsule technology is a technology in which a solid or liquid (core material or inner phase) is coated with a film-forming material (wall material or outer ph...
