Simple degumming method of concentrated-fragrance colza oil

Abstract

The invention relates to a simple degumming method of concentrated-fragrance colza oil. The degumming method comprises the following steps of: (1) pumping squeezed concentrated-fragrance colza crude oil with slag removed into a degumming tank, wherein the concentrated-fragrance colza crude oil does not need to be heated or cooled and just is operated at normal temperature; (2) adding a degumming absorption agent into the degumming tank; (3) stirring for 15-20min at room temperature; and (4) filtering and separating the absorption agent by using a plate frame filtering machine of which the filtering aperture is 5mu m, so as to obtain the refined concentrated-fragrance colza oil. The degumming absorption agent is prepared from montmorillonoid, silicate, modified bentonite and filter aids with different apertures which are mixed and stirred. According to the simple degumming method, the gum impurities such as phospholipids and protein in the concentrated-fragrance colza oil are absorbed by using the degumming absorption agent and then filtered and separated, thus degumming the concentrated-fragrance colza oil; and the conventional process that the concentrated-fragrance colza oil stands for a long time or is subjected to hydration degumming firstly and then dried and dehydrated is replaced, both the gum impurities can be simply and rapidly eliminated, and the concentrated fragrance of the oil is not lost, so that colza oil which is fragrant, pure in quality, nutritive and sanitary is obtained.

Description

technical field [0001] The invention relates to the field of edible oil processing, in particular to a degumming method for fragrant rapeseed oil which can simply and quickly remove colloidal impurities such as phospholipids and proteins in the fragrant rapeseed oil while maintaining the pure and strong aroma of the rapeseed oil. Background technique [0002] Luzhou-flavored rapeseed oil is a traditional edible oil in my country. It is widely used in cooking fields such as cooking and frying. It is deeply loved by consumers for its unique flavor of roasted rapeseed. Phospholipids are mainly phospholipids. Although phospholipids are nutrient-rich and have anti-oxidative and synergistic effects on oils, their presence in oils will affect the appearance and quality of oils. In the industry, it is usually necessary to reduce the content of phospholipids to a certain level. This requires degumming craft to complete. [0003] There are two main degumming processes for the aromatic ...

AI Technical Summary

Problems solved by technology

[0005] The present invention overcomes the defects of the above-mentioned prior art, provides a simple and fast degumming process of fragrant rapeseed oil, greatly shortens the storage time of rapeseed oil in the long-term standing process, thereby avoiding the Hara taste caused by the increase of acid value and peroxide value; at the same time, it also avoids the high hydration temperature, long dephosphorization time, high refining consumption, high energy consumption, difficult oil foot treatment and large flavor loss in the hydration degumming process and other defects, completely retain the unique aroma of fried seeds of Luzhou-flavored rapeseed oil, and the flavor of rapeseed oil is pure and strong, which greatly improves the quality of rapeseed oil
