Problems solved by technology

In CN 105454438 A, the surface oil content of the prepared soybean powder oil is low, and the flavor stability during storage is significantly improved, but antioxidants and / or emulsifiers need to be added
In CN 105285159 A, the prepared soybean powder oil has good quality, high oil content and no oil leakage, but it also needs to add emulsifier phospholipid and exogenous wall material maltodextrin, and enzymatic hydrolysis, separation, etc. are required in the preparation process steps, the process is more complicated
In CN 105722399 A, the formula contains soymilk and medium-chain fatty acid glycerides, which can effectively suppress bean odor, fishy smell, astringency and other flavors, but it is limited to the scope of emulsion

[0043] Preparation method of powder oil

[0044] A preparation method of powdered oil, said preparation method comprising steps:

[0045] (1) Provide soy milk base material;

[0046] (2) heat-treating the soymilk base material and high-pressure homogenizing treatment to obtain the treated soymilk;

[0047] (3) adding vegetable oil to the soybean milk obtained in step (2), and emulsifying to obtain an oil-in-water emulsion;

[0048] (4) The emulsion obtained in step (3) is spray-dried.

[0049] In some specific embodiments, the solid content of the soybean milk base material is 6% or more, preferably 10% or more.

[0050] In some specific embodiments, the content of fat in the soybean milk base material is 25%-35% of the total solid content.

[0051] In some specific embodiments, the vegetable oil is selected from: rice oil, sunflower oil, high oleic sunflower oil, canola oil, rapeseed oil, palm oil, palm kernel oil, peanut oil, rapeseed oil, soybean oil , cottonseed oil, ...

Embodiment 1

[0108] Take 1000 parts of soymilk base material (solid content is 10%, and oil content is 30% of the total solid content) into a high-temperature and high-pressure reactor, react at 120°C for 1 hour, and then homogenize under high pressure in a homogenizer for 3 minutes. The pressure is 50MPa to obtain the reaction solution; take 425 parts of the reaction solution, add 7.5 parts of corn oil, stir at high speed for 1min, and the rotation speed is 15000rpm, then homogenize under high pressure for 3min, the homogenization pressure is 40MPa, spray the obtained emulsion to obtain powder oil .

Embodiment 2

[0110] Take 1000 parts of soybean milk base material (solid content is 6%, and oil content is 25% of the total solid content) and put it into a high-temperature and high-pressure reaction kettle, react at 110°C for 0.5h, then homogenize under high pressure in a homogenizer for 3min, homogenize The mass pressure is 50MPa to obtain the reaction solution; take 425 parts of the reaction solution, add 7.5 parts of rice oil, stir at a high speed for 1min, and the rotating speed is 15000rpm, then high-pressure homogenization for 3min, the homogenization pressure is 40MPa, and the obtained emulsion is spray-dried to obtain a powder grease.

Abstract

The invention provides a preparation method of powdered oil. The preparation method comprises the following steps: (1) providing a soybean milk base material; (2) performing heat treatment and high-pressure homogenization treatment on the soybean milk base material to obtain treated soybean milk; (3) adding vegetable oil into the soybean milk obtained in the step (2), and emulsifying to obtain an oil-in-water emulsion; and (4) carrying out spray drying on the emulsion obtained in the step (3). The powdered oil disclosed by the invention is good in stability, low in surface oil content and high in embedding rate.

Description

technical field [0001] The invention relates to the field of oils and fats, in particular to powdered oils and a preparation method thereof. Background technique [0002] Microcapsule technology is a technology that uses natural or synthetic film-forming materials (wall materials) to embed solid particles, liquids and even gases (core materials) to form tiny particles. have a wide range of applications. Powdered oil is a solid oil product prepared by using oil as the core material, selecting appropriate wall materials and an appropriate amount of emulsifier, and preparing through microencapsulation technology. Powdered oil can not only maintain the function and characteristics of the oil itself, but also give it new features, such as masking the bad smell of the core material, gradually slowing the release of the core material, and significantly improving the antioxidant capacity of the oil, etc. [0003] With the improvement of health and safety awareness, more and more c...
