Abstract

PROBLEM TO BE SOLVED: To provide a degumming method whereby phospholipids can be hydrolyzed more efficiently with phospholipase even at high temps. (e.g. 70 deg.C) or higher); and phospholipase can be recovered and reused. SOLUTION: In a method for removing a gummy substance from an oil or fat by hydrolyzing phospholipids in the oil or fat with phospholipase A1 and/or A2 and removing the resultant hydrolyzate, the hydrolysis is conducted by using phospholipase immobilized on a cation exchanger comprising a hydrophobic support and cation exchange groups. Thus, the degumming can be carried out efficiently even at such a high temp. that the oil or fat loses its viscosity. Since an immobilized enzyme can be recovered and recycled, the degumming is done economically.

2. Description of the Related Art Crude oil squeezed from soybeans, palm seeds, rice bran, and the like contains a gum substance mainly composed of phospholipids. Gum contained in crude oil degrades the quality of fats and oils, and thus needs to be removed by a degumming step. Conventionally, phospholipase has been used in the degumming step. Phospholipase can hydrolyze phospholipids, which are the main components of gum, so that gum can be hydrolyzed and removed.

However, the currently used phospholipase has relatively low thermostability, so that it is easily deactivated at high temperatures at which fats and oils lose viscosity, so that phospholipids cannot be efficiently hydrolyzed.

Since lysophospholipids and fatty acids, which are hydrolysis products, are easily released into the reaction solution, it has been found that the reactivity between phospholipases A1 and / or A2 and phospholipids increases.

The immobilization to the cation exchanger comprising the hydrophobic carrier 2 and the cation exchange group can be performed via the cation exchange group as follows. That is, the cation exchange group is activated with thionyl chloride, carbodiimide, or the like. Thereafter, the activated cation exchange group is reacted with phospholipase A1 and / or A2, and both are covalently bonded. Thereby, the phospholipases A1 and / or A2 can be immobilized on the cation exchanger. Phospholipase A
Since 1 and A2 are acidic proteins, they do not easily bind to the cation exchange group due to electrostatic repulsion in the neutral region, but have a weak electrostatic repulsion below the isoelectric point, and It becomes easier to combine. Therefore, the reaction between the activated cation exchange group and the phospholipase A1 and / or A2 is preferably performed at an isoelectric point or lower.

The immobilized phospholipases A1 and / or A2 immobilized on a cation exchanger comprising a hydrophobic carrier and a cation exchange group may be a carrier other than the above cation exchanger (for example, an anion exchanger). Etc.) immobilized on phospholipase A1 and / or A2, has higher reactivity with phospholipid as a substrate. This is considered to be due to the following reasons. That is, since the phospholipid is rich in hydrophobicity, it is easily adsorbed on the hydrophobic carrier portion of the cation exchanger, and as a result, the immobilized phospholipases A1 and / or A2 immobilized on the cation exchanger are combined with the phospholipid. Is considered to be more responsive. On the other hand, among the fatty acids and lysophospholipids that are the hydrolysis products of phospholipids, lysophospholipids are rich in hydrophilicity, so they are easily separated from the hydrophobic carrier portion of the cation exchanger and easily removed in water,
Further, since the other fatty acid of the hydrolysis product has a negative charge, it is considered that the other fatty acid is easily separated from the cation exchanger due to electrostatic repulsion with the cation exchange group portion of the cation exchanger. As a result, fatty acids and lysophospholipids, which are hydrolysis products of phospholipids, are easily released from the immobilized phospholipases A1 and / or A2 immobilized on the cation exchanger, and the immobilized immobilized phospholipases are immobilized on the cation exchanger. It is considered that the reaction between the phospholipase A1 and / or A2 and the phospholipid is less likely to be hindered.

[Example 2] Hydrolysis of phospholipid by immobilized phospholipase Using the two types of immobilized phospholipases prepared in Example 1, hydrolysis of phospholipid, which is a main component of gum in oils and fats, was performed as follows. I went like that. (1) 25 g of crude rice bran oil containing 300 ppm of phosphorus and 1 mL of water
And 0.6 g of immobilized porcine pancreatic phospholipase A2 immobilized on Amberlite IRC-50 were added to hydrolyze the phospholipids in the crude oil. The hydrolysis was performed at 80 ° C. for 15 minutes.
After hydrolysis, the mixture was centrifuged at 4000 rpm for 12 minutes, separated into an aqueous layer and an oil layer, and the phosphorus content in the oil layer was determined. The quantification of the phosphorus content in the oil layer was carried out by using the colorimetric method of the standard method for testing fats and oils (Japan Oil Chemicals Association). As a result, the phosphorus content in the crude oil was 160 ppm.

From Table 1, it was found that phospholipids in crude oil cannot be sufficiently removed only by centrifugation.
It was also found that even if water was added and centrifuged, the phospholipids in the crude oil could not be sufficiently removed. Meanwhile, the table
From 1, after hydrolyzing phospholipids in crude oil using immobilized porcine pancreatic phospholipase A2 immobilized on Amberlite IRC-76 or immobilized porcine pancreatic phospholipase A2 immobilized on Amberlite IRC-50, It was found that the phospholipids in the crude oil could be sufficiently removed by centrifugation.

The phosphorus removal rate by immobilized porcine pancreatic phospholipase A2 immobilized on Amberlite IRC-76 is different from the phosphorus removal rate by immobilized porcine pancreatic phospholipase A2 immobilized on Amberlite IRC-50. Thus, it was found that even with the same phospholipase, the rate of hydrolysis of phospholipids by the immobilized phospholipase can be changed by changing the hydrophobic carrier to be immobilized. Therefore, it was clarified that phospholipids in fats and oils can be more efficiently hydrolyzed by selecting an appropriate hydrophobic carrier.
