Embodiment 1

[0024] A kind of auxiliary blood fat reducing corn oil processing technology, including alkali refining, filtration, decolorization and deodorization;

[0025] In the process of alkali refining, after mixing the lye and corn oil, a mixed liquor is obtained; the concentration of the lye is 65%, and the temperature of the alkali refining is controlled by means of temperature programming to obtain the alkali refining liquor;

[0026] The temperature programming process is as follows: measure the initial temperature of the mixture, use it for 5 minutes, raise the temperature of the mixture to 45°C, and maintain it at 45°C for 45 minutes. During this time, flocculation begins to appear and disperse evenly; Raise to 80°C and maintain for 15 minutes. During this time period, the flocculation particles become larger rapidly, which is convenient for the subsequent treatment of the alkali refining solution;

[0027] During the filtration process, use suction filtration to filter the alk...

Abstract

The invention provides a processing technology for corn oil capable of assisting in reducing blood fat. The processing technology comprises the steps of alkali refining, filtering, decolorizing and deodorizing. In the process of alkali refining, an alkali refining temperature is controlled in a programmed heating mode, the highest temperature of programmed heating is 80 DEG C, and alkali refining liquid is obtained; and in the process of deodorization, the pressure of a deodorization tower is controlled to be 0.6 mbar, a deodorization temperature is 200-220 DEG C, and deodorization time is 20-35 min. The processing technology has the advantages of being reasonable in design and easy to operate. In the corn oil obtained by the processing technology, the loss rate of sterol is within 5%.

Description

technical field [0001] The invention relates to the technical field of vegetable oil refining, in particular to an auxiliary blood fat-reducing corn oil processing technology. Background technique [0002] Sterols, also known as sterols, are important natural active substances, including animal sterols, phytosterols, and fungal sterols. Phytosterols exist in multiple tissues of plants, such as stems, leaves, fruits, etc. When extracting oil from plant seeds, they will enter the vegetable oil along with the extraction process. [0003] Phytosterols are an important component of plant cells. After entering the human body, they can compete with cholesterol, thereby reducing the body's absorption of cholesterol, thereby reducing the low-density lipoprotein cholesterol in the blood. blood lipid content. [0004] With the increasing use of vegetable oils, people are paying more and more attention to the sterol content in vegetable oils. The production process of vegetable oil m...
