Description of the Related Art As a continuous hydrolysis method of fats and oils using an enzyme, a fats and fats-decomposing enzyme (lipase) is immobilized on a resin or a membrane, and a batch stirring type multistage reactor, a packed tower or a membrane reactor, etc. There is a method in which an oily substrate and a water-soluble substrate are used as a reactor, and the oily substrate and the water-soluble substrate are allowed to flow countercurrently or in parallel (Japanese Patent Laid-Open No. 61-61).
85195, JP-A-63-59896, and JP-A-1-98494). However, whichever method is used, the apparatus becomes complicated and the operation method of the enzyme tower is very difficult. Furthermore, a reaction example of a batch circulation system is disclosed in JP-A-58-58.
As disclosed in Japanese Patent No. 146284, it is a method of using a lipase immobilized on a polysaccharide gel containing a large amount of water and adding only oils and fats without adding an aqueous phase substrate, and repeatedly used. If the number of times is increased, the water required for decomposition may be insufficient, and further, glycerol, which is a water phase product, may be accumulated in the immobilized enzyme, and equilibrium may not work to obtain a sufficient decomposition rate. In addition, JP-A-4-33588
In Japanese Patent Laid-Open No. 1, a reactor is proposed which circulates a reaction solution in which the amount of water is uniformly mixed and the amount of water is uniformly maintained. Process and incidental equipment are required.

用しないで済む。Means for Solving the Problems The present inventor uses an immobilized enzyme for the recovery of the enzyme, and the separation of the oil phase and the aqueous phase repeats the reaction while performing natural separation in a supply tank for these substrates. Therefore, it is possible to solve the reaction rate and the separation of products, which have been problems in the past, and further, since the apparatus is composed of only the enzyme tower and the substrate supply tank, the equipment is simple and the operation method is simple and stable operation is possible. At the same time, it is a batch system with low capital investment
The method of hydrolyzing the oils and fats was discovered. That is, according to the present invention, the oil phase and the aqueous phase are separated in a supply tank without stirring, and these are extracted through separate pipes and brought into contact with an enzyme, and the reaction liquid flowing out from the enzyme tower is oil phase in the supply tank. The above-mentioned problem is solved by separating into an aqueous phase and repeating this. Yo
More specifically, the present invention relates to an enzyme tower using an immobilized enzyme.

A method for hydrolyzing fats and oils, in which the reaction liquid is discharged from the enzyme tower.
The output part is in the oil phase of the substrate supply tank and near the interface with the water phase
The reaction solution is circulated between the enzyme tower and the substrate supply tank.
In addition to forming an oil-water interface in the substrate supply tank,
The position above the middle part of the oil phase of the substrate supply tank, the water phase substrate

Batch type oil that is supplied to the enzyme column without premixing with the substrate
It is a method of hydrolyzing fat. In the present invention, the pipe for returning the reaction liquid to the substrate supply tank is immersed in the separation upper layer so as not to disturb the oil-water interface, and the circulation flow rate of the reaction liquid is adjusted. As a result, a sufficient reaction rate can be obtained by using a packed column of immobilized enzyme, and the loss of enzyme can be suppressed. Furthermore, by using the difference in specific gravity between the oil phase and the water phase in the supply tank, it is not necessary to use any special device for oil / water separation.

も酵素塔と同様に加温できるものがよい。The substrate supply tank which also serves as the oil-water separation tank does not have a stirring device. It has a pipe for separately extracting the oil phase and the water phase, which have been separated by standing, and sending them to the enzyme tower. Further, it has a pipe for returning the reaction liquid flowing out from the enzyme tower. The oil phase extraction pipe is provided with an extraction port at a position above the middle part of the oil phase. On the other hand, the water phase extraction pipe has an extraction port at the bottom of the substrate supply tank. Further, the return pipe for the reaction solution has a return port at a position where it does not disturb the interface between the oil phase and the water phase. These positions vary depending on the production amount (reaction liquid flow rate) and the amount of enzyme used, and may be adjusted accordingly. Further, the shape (tank height / tank diameter, etc.) of the substrate supply tank may be designed so that oil-water separation can be performed well. It is preferable that this substrate supply tank also be capable of heating like the enzyme tower.

Shed. Up to now, a countercurrent type reaction device has been proposed, but in a liquid (oil / fat) -liquid (water) system reaction, it is quite difficult to flow in a packed column in a countercurrent, and it is complicated and requires a device. Become. Therefore, in the present invention, the liquid (oil / fat) -liquid (water) flow in parallel, that is, in the same direction, and are mixed at the outlets of the oil phase and water phase supply pumps and sent to the enzyme tower.

Can be determined by In order to obtain a high decomposition rate, it is necessary to use a random type immobilized enzyme and increase the amount of water added. It is desirable to supply the oil phase and the water phase to the enzyme tower at the initial charge ratio.

A lipase obtained by immobilizing a commercially available lipase (Lipase OF Meitosu Sangyo Co., Ltd.) on an ion exchange resin (Duolite A-568 Diamond Shamrock) at a filling height of 150 mm)
24 g was filled. On the other hand, a glass container with a jacket 1
160 g of soybean oil was added to (inner diameter 40 mm, height 300 mm). Warm water at 40 ° C was circulated in the substrate supply tank 1 and the jacket of the enzyme tower 2 so that the reaction temperature was 40 ° C. Soybean oil was sent to the enzyme tower using the pump 7 at a flow rate of 5 g / min, and when the oil flowed out from the return line 3, 96 g of distilled water was added to the substrate supply tank 1. The amount of water added is 60% by weight (based on the oil phase substrate). At this time, water separated into lower layers and soybean oil into upper layers to form a clean interface. After that, the lower end of the oil phase extraction line 4 (inner diameter 3.5 mm) was installed at a position 10 mm from the upper end of the oil phase. Furthermore, the lower end of the reaction liquid return line 3 is 10 mm above the interface.
It was installed in the position. After this, the substrate supply lines 4 and 5
Pump the oil phase through pump 7 and the water phase through pump 6 through 5
It was supplied at a rate of 3 g / min. This flow rate was maintained until the end of the reaction so that the weight ratio of the aqueous phase was 60% by weight (to the oil phase). When the reaction liquid flowing out from the return line 3 exited the lower end of the return line, it was separated into an oil phase and an aqueous phase and did not disturb the oil-water interface. As the reaction progressed, the oil phase became cloudy. This was due to the emulsifying action of monoglyceride formed during the decomposition, but the interface did not disappear. As the reaction proceeded further, monoglyceride was also decomposed and a clear oil phase appeared. The sample was withdrawn from the oil phase of the substrate supply tank 1 over time, the acid value (AV) and the saponification number (SV) were determined, and the decomposition rate was determined by dividing the acid number by the saponification number. Finally, the decomposition rate of soybean oil reached 96%. Further, the water content of the oil phase immediately after the reaction was measured by the Karl Fischer method, and it was 0.5%, which confirmed that good oil-water separation was achieved. FIG. 2 shows the change over time in the decomposition rate of the oil phase when the circulation stationary separation type reactor shown in FIG. 1 was used.
