The present invention relates to a method for producing a lipase reactant, and more particularly to a method for producing a lipase reactant characterized by carrying out a lipase reaction in a supercritical state. In the present invention, a supercritical solvent (sometimes simply abbreviated as "supercritical gas") is used, which refers to a fluid that exceeds a critical temperature T c and a critical pressure P c . In recent years, various extraction and separation techniques that apply the physical properties of supercritical gases have been developed. Supercritical gas extraction takes advantage of the fact that supercritical fluid exhibits excellent solubility for many substances, and the solubility changes with changes in temperature and pressure, such as hops, spices, and nicotine. It is applied to the extraction operation of caffeine, etc. The present inventors have conducted various studies on the lipase reaction, and found that the lipase reaction proceeds even under harsh conditions that are unprecedented for living organisms, such as supercritical conditions (for example, 31.1°C or higher and 73 atmospheres or higher for carbon dioxide). However, the present invention was completed based on the discovery that there are other advantages, such as ease of separation after the reaction, and the fact that the reaction, which was conventionally carried out in a heterogeneous system, proceeds in a homogeneous phase. That is, the present invention brings a mixture containing (a) lipase, (b) one type or a combination of two or more of oils and fats and fatty acids, and (c) a substance that can serve as a solvent in a supercritical state to a supercritical state. This is a method for producing a lipase reaction product, which is characterized by maintaining the temperature at a temperature at which the lipase reaction proceeds. The lipase used in the present invention may be any proteinaceous polymer organic catalyst produced by living cells.
Structurally stable lipases that retain their properties are useful. A substance that is reacted with the lipase, generally known as a substrate, is used in correspondence with the above-mentioned lipase. Hereinafter, a case will be described in which a lipase is used as a lipase, and a fat or oil, or one or more kinds of fats and oils and fatty acids is used as a substance to be reacted with the lipase, but the present invention is not limited thereto. First, regarding the lipase, Rhizopus deremer, Rhizopus alhizas, Aspergillus niger, Candida cylindrace, Diyoautrichum candidaum, etc. can be used. Examples of oils and fats include vegetable oils such as palm oil, soybean oil, rapeseed oil, olive oil, coconut oil, corn oil, cottonseed oil, and safflower oil, animal fats such as beef tallow, lard, and fish fat, and trilaurin, tristearin, and triolein. It refers to synthetic oils and fats, and the fatty acids are straight chain fatty acids with 8 to 20 carbon atoms, such as palmitic acid, stearic acid, oleic acid, linoleic acid, and linoleic acid, and one or more of these can be used. can. When using a commercially available enzyme agent, the amount of lipase used is 0.025 to 5% by weight based on the raw material oil or fatty acid (5 x 102 to 5 x
10 5 units of lipolytic enzyme) is used. Furthermore, the transesterification reaction of fats and oils by lipase can be promoted by carrying out the transesterification reaction of fats and oils in the presence of an inert organic solvent and/or a carrier.
As the inert organic solvent, petroleum benzene, n-hexane, petroleum ether, etc. can be used, and as the carrier, commonly used carriers such as celite, activated carbon, alumina, silicic acid, cellulose, etc. can be used. In addition to the enzyme and the substance to be reacted with the enzyme, a substance that can serve as a solvent in a supercritical state is mixed.
Specific examples include ethane, ethylene, propane, propylene, and nitrogen oxide, but carbon dioxide is a harmless inert gas, and its critical point is near room temperature, so it is necessary to maintain the temperature at which the enzymatic reaction proceeds. It is the easiest to handle due to its suitability. Such a mixture is brought into a supercritical state and maintained at a temperature at which the enzymatic reaction proceeds. Specifically 10℃
The temperature range is preferably from 50°C to 50°C. When carbon dioxide is used, the critical temperature T c is 31.1°C and the critical pressure P c is 73 atm, which is particularly preferable, but since carbon dioxide dissolves in a reaction system using water, the pH is also suitable for enzymatic reactions. It is necessary to adjust it so that the value is the same. Reactants can be recovered by increasing and/or decreasing the pressure and/or temperature of the reaction system. This recovery process can be applied to general supercritical gas extraction operations, such as by reducing pressure, separating by increasing temperature, and separating by placing an adsorbent that adsorbs only the target component in a separation tank. This can be done by, for example. Since the lipase reaction of the present invention is carried out in a supercritical state, it is easier to handle the lipase in subsequent separation steps if it is immobilized. As carriers for immobilizing enzymes, carriers such as polysaccharides such as cellulose, porous glass, and ion exchange resins can be used, and enzymes can be immobilized onto these by physical adsorption, ionic bonding, or covalent bonding. can be made into Most carriers are granular, but there are also membrane-like,
It can also be shaped into a plate, a tube or a fiber.
In addition, among the methods of cross-linking the enzyme by reacting it with a reagent having a bifunctional group, and the method of encasing the enzyme in a gel lattice or coating it with a selectively permeable polymer film, there are methods in which the enzyme is placed in a supercritical solvent. It may be immobilized by a method that functions in The enzyme reaction apparatus may be a batch method, but it is also possible to carry out the reaction continuously by using an immobilized lipase column or by circulating the enzyme using an ultrafiltration membrane. Next, the method of the present invention will be explained using the drawings. 1st
Raw materials are fed into a reaction vessel 1 whose temperature can be controlled as shown in the figure. The raw materials can be stirred using a magnetic stirrer 2. The carbon dioxide gas supplied from the carbon dioxide cylinder 3 is pressurized by the liquid chromatography pump 4 while passing through a secondary pressure control valve 5, a stop valve 6, a trace control valve 7, a safety valve 8,
The pressure is controlled by stop valves 6', 6'', 6, etc., and the liquid is supplied to the reaction vessel 1. After the lipase reaction is carried out in a supercritical state for a certain period of time, the reaction vessel is cooled and carbon dioxide is turned into dry ice together with the reactants. Then, after opening the valve, the reactant is recovered by sublimating dry ice at room temperature.The reactant can be extracted with hexane etc. to separate the lipids.The carbon dioxide is connected in parallel and the enzymatic reaction begins. It is possible to feed the raw material to the second reaction vessel through a suitable repressurization device. In addition, when using immobilized enzyme, the reactor/separator system should be as shown in Figure 2. In this case, the substances produced by the continuous reaction can be separated in the separator 1 and the separator 22 by increasing and/or decreasing the pressure and/or temperature by taking advantage of the characteristics of supercritical fluid. That is, the immobilized enzyme column 10 is placed in the reaction vessel 1, and the substrate inlet 11 is connected to the carbon dioxide supply line.
Furthermore, a line 12 and a valve (three-way valve) 13 are provided for cleaning after continuous reaction for a certain period of time. The enzyme reaction product is passed through a line filter 14, six-way valves 15, 15',
It passes through quick connectors 16, 16' and is separated from carbon dioxide in separators 17, 17'. Pressure is adjusted using six-way valves 15, 15', primary pressure regulating valve 5', pressure gauge 9'', 9-flow meter 18, and three-way valve 13'.
Adjustments are made as appropriate. In the conventional method, the reaction was carried out at room temperature and pressure, so the reaction system rarely became a homogeneous liquid with high fluidity, resulting in poor reactivity.However, in the present invention, enzymes are By carrying out the reaction, it becomes possible to make the reaction system homogeneous. Also,
Supercritical gases have a lower viscosity and higher diffusion coefficient than liquid solvents, so they can easily penetrate solids, and it takes less time for reactions to reach equilibrium. Furthermore, it is easy to separate the supercritical gas and the reactants, and the fractionation process is simple. It has the advantage that non-volatile components obtained through enzymatic reactions and reactants sensitive to heat can be processed at temperatures close to room temperature. Furthermore, it has been discovered that even in a supercritical state, which is harsh for living organisms, the activity of the enzyme does not decline and the enzymatic reaction proceeds. Example 1 Experimental method Stirrable liquid chromatography column packings with an internal volume of 40 ml were used as reaction vessels 1 and 1', and two were connected in parallel. Figure 1 shows a schematic diagram of the experimental apparatus. In this reaction vessel, 0.2 g of triolein (manufactured by Hanui Chemical),
Lipase originating from Rhizopus delemar (manufactured by Seikagaku Corporation, code number 100890) 0.1g or 0.2g,
0.2 ml of 0.3M TES buffer (manufactured by Wako Pure Chemical Industries, Ltd., PH6.8) and 1 g of Celite (manufactured by Wako Pure Chemical Industries, Ltd.) were added. Liquid carbon dioxide is pumped into the reaction vessel using a liquid chromatography pump (JASCO Corporation).
TRIROTAR) 4 was used to increase the pressure while feeding, and when the pressure reached 100 atmospheres, stirring was started, and the reaction was carried out at 32°C for a certain period of time shown in Table 1. During the reaction, the pump was operated continuously, and the pressure inside the reaction vessel was kept constant using the secondary pressure control valve 5 and the safety valve 8. After the reaction was completed, the container was cooled with acetone and dry ice, and the reactants were collected in dry ice.
Conversion to dry ice was confirmed using a pressure gauge 9. After sublimating dry ice at room temperature, the residue was extracted with hexane to separate lipids. Analysis method: The reaction product separated in hexane was separated into 7% hydrated Florisil (Hani Chemical, 60-80 mesh, 30
In addition to the column in g), develop with a mixed solvent of diethyl ether/hexane with a volume ratio of 20:80.
80ml fractions were collected and concentrated under reduced pressure. Transfer a small amount of the concentrate to a TLC plate (silica gel-60, No. 5747,
Merck) and developed with a mixed solvent of hexane, ethyl ether, and acetic acid in a volume ratio of 70:30:1.
It was confirmed that monoglycerides and diglycerides were not included. After drying the concentrate, fatty acid methyl ester was prepared by the BF 3 methanol method (NOF Standard Analysis Method 2, 4, 20, 2-77), and quantitative analysis was performed by gas chromatography.
