Problems solved by technology

However, phosphatidic acid can form a stable salt with the residual calcium and magnesium ions in the oil and become a non-hydratable phospholipid. The phospholipase cannot contact the substrate, resulting in incomplete degumming
In the oil refining process, phosphatidic acid is usually converted into hydratable phosphatidic acid by adding chelating agents such as citric acid, and then the pH is adjusted to the range where the enzyme can react for degumming. This method causes waste of raw materials by adding excessive acid and alkali. And bring secondary pollution
[0007] The above degumming methods have cumbersome steps, and the process in the process is to speed up the reaction speed, or add other enzymes to assist degumming. At present, there is a lack of a simple and easy method that can convert both hydratable phospholipids and non-hydratable phospholipids. to the reaction product

Embodiment 1

[0076] Take 50 g of soybean crude oil (acetone-insoluble content 3%), add 0.5 ml of phospholipase C diluted 200 times, 1 ml of water, homogenize for 30s with a homogenizer (Fluka, Germany), and then react at 50°C for 1h on a heating table. At the end of the reaction, the temperature was raised to 85°C and kept for 0.5h. The oil was centrifuged at 8000 rpm for 20 min, and the upper sample was taken for liquid phase analysis of the increase in diglyceride DG. The results are shown in Table 1.

Embodiment 2

[0078] Take 50 g of soybean crude oil (acetone insoluble content 3%), add 0.5 ml of phospholipase C diluted 200 times, 1 ml of water, add 0.03 g of degumming aid composition cation exchanger artificial zeolite P103640 (Aladdin reagent company), white Carbon black Degussa Aerosil 200, 0.27g, and then reacted on a heating table at 50°C for 1h. At the end of the reaction, the temperature was raised to 85°C and kept for 0.5h. The oil was centrifuged at 8000 rpm for 20 min, and the upper sample was analyzed by liquid phase for the increase of diglyceride DG. The results are shown in Table 1.

Embodiment 3

[0080] Take 0.5 ml of phospholipase C diluted 200 times, add 0.03 g of artificial zeolite P103640 (Aladdin Reagent Co., Ltd.), 0.27 g of silica Degussa Aerosil 200, 3 ml of water, mix at room temperature overnight, remove the supernatant, and the remainder Put it in a ventilated place to dry, put the dried powder in 50g of soybean crude oil (acetone intolerant content is 3%), add 1ml of water, and react at 50°C for 1h on a heating table. After the reaction, the temperature is raised to 85°C and kept for 0.5h , the oil was centrifuged at 8000 rpm for 20 min, and the upper oil sample was taken to analyze the increase in diglyceride DG. The results are shown in Table 1.

Abstract

The invention provides a degumming aid composition for enzymatic degumming and a grease degumming method. The degumming aid composition provided by the invention includes a cation exchanger and a porous powder dispersant. The grease degumming method provided by the invention comprises adding phospholipase C, water, and a degumming aid composition to the grease to be degummed, performing degumming reaction; and solid-liquid separation. By adopting the method of the invention, the degumming step is simplified, the degumming efficiency is improved, part of the non-hydratable phospholipid can be changed into hydratable phospholipid, and the dispersibility of the phospholipase is increased.

Description

technical field [0001] The invention belongs to the technical field of oils and fats, and in particular relates to a degumming aid composition and application thereof. Background technique [0002] Phospholipase C (phospholipase C), referred to as PLC, is a wide-ranging enzyme that acts on the first glycerophosphate bond at the C3 site of phospholipids. It can hydrolyze phospholipids into diglycerides and phosphate groups in oil refining, improve degumming efficiency, and has great application potential. At present, the research of degumming process mainly focuses on the compounding of different phospholipases to expand the substrate range, improve the hydrolysis rate of phospholipids, and add chelating agents to chelate metal ions, so that non-hydratable phospholipids become hydrated phospholipids, and then the degumming step is carried out. Immobilization of phospholipase for repeated use to increase enzyme lifetime, and various methods of changing parameters from the pro...
