Embodiment Construction

[0019] The present invention will be further described with an embodiment below:

[0020] A production method of soybean essential oil, specifically comprising the following steps:

[0021] Soybean crude oil is filtered with 120 orders / inch crude oil coarse filter to remove slag;

[0022] The leached crude oil after coarse filtration is heated to about 85 ℃ by a plate heat exchanger;

[0023] Add food-grade phosphoric acid with a concentration of 85% to the heated soybean oil for acid refining and degumming, the dosage is 0.05%-0.1% of the oil, and the reaction time is about 25min-30min;

[0024] Use alkali to neutralize free fatty acids, so that free fatty acids can form soapstock;

[0025] Two centrifugal separations are carried out on the crude soybean oil after alkali refining and deacidification: the first centrifugal separation is composed of two centrifuges, the first centrifuge separates the oil and soapstock, and the oil enters the second centrifuge as a light phase...

Abstract

The invention provides a production method of refined soybean oil, and belongs to the technical field of edible oil processing. The production method comprises the steps of coarse filtering, heating, acid refining to remove colloid, alkali refining to remove acid, primary centrifugal separating, secondary centrifugal separating, drying, discoloring, filtering, discolored oil refining, deodorizing, and deodorized oil refining. The erucic acid and phosphatide contents of the refined soybean oil prepared by the provided production method are both qualified, moreover, the refined soybean oil does not generate oil smoke at a high temperature, and thus the refined soybean oil can be used to high-temperature cooking modes such as frying, stir frying, and the like.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, in particular to a production method of soybean essential oil. Background technique [0002] Soybean oil is a kind of oil extracted from soybeans, usually we call it "soybean salad oil", and it is one of the most commonly used cooking oils. The traditional production of crude soybean oil adopts pressing method, and its technological process includes material sorting, high temperature heating, flaking, pressing and filtering. Soybean oil produced by traditional techniques is too high in phospholipids, and will produce a lot of oily fumes at high temperatures, which is extremely harmful to human health. Contents of the invention [0003] The method for producing soybean essential oil provided by the invention can significantly reduce the contents of erucic acid and phospholipids in the oil, and is more beneficial to the health of eaters. [0004] For this reason, the invention pro...
