Embodiment 1

[0026] A production process of enzymatically refined soybean oil, the production process of said enzymatically refined soybean oil comprises the following steps:

[0027] (1) Filtration and separation: place the obtained soybean crude oil in a centrifuge, remove the precipitate after high-speed centrifugation, collect the supernatant, and then place the supernatant in a filter tank to fully filter to obtain the filtrate for subsequent use;

[0028] (2) Hydration degumming: heat the above filtrate to 50°C, then pour warm water at 50°C into it, then add sodium chloride, stir well, add the mixed solution into the reaction kettle and feed supercritical carbon dioxide, After keeping warm, take out the mixed solution and continue to stir and then filter to obtain preliminary degummed oil for later use;

[0029] (3) Enzymatic degumming: adjust the pH of the above-mentioned preliminary degumming oil to 6.5, then add phospholipase, shake and homogenize at 60°C for 2 hours, take it out,...

Abstract

The invention provides a production process for refining soybean oil by an enzymic method, and relates to the technical field of soybean oil refining. The production process mainly comprises the following steps: filtering and separating, hydrating and degumming, enzymatically degumming, decoloring, purifying with ethanol and the like. The method overcomes the defects in the prior art, improves thedegumming rate of soybean crude oil, effectively reduces the impurity content in the crude oil, improves the quality of refined oil, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of soybean oil refining, in particular to a production process for enzymatically refining soybean oil. Background technique [0002] Soybean oil is obtained from soybean seeds, and soybean oil is the most produced oil in the world. There are many types of soybean oil, which can be divided into pressed soybean oil and leached soybean oil according to the processing method. Because soybean oil is rich in nutritional value and low in cost and easy to obtain, it is one of the most widely used edible oils. [0003] Because soybean oil contains a lot of colloids after extraction, and the colloids in crude oil are the main factors affecting the quality of refined oil, because these colloids often cover the fine particles of oil, so that the oil and the catalyst are not in contact, thus Reduce the cracking speed, and at the same time, the high colloid content will cause the oil to be easily emulsified, easy to foam...
