The present invention relates to a method for separating and collecting aroma components from joints, and more particularly, to a method for easily and efficiently recovering aroma components present in joints by combining extraction and evaporation. It is. Conventionally, the aromatic components of joints have been extracted by hot water extraction, in which flavor components and aromatic components are collected as a so-called "dashi", or by extraction and collection using an organic solvent. However, in the former method, that is, adding water to the joints and collecting them as dashi through multistage countercurrent extraction, etc.,
There is a large amount of aroma remaining in the extraction residue, and a large amount of water and energy are required to recover the aroma in a good yield.
The use of organic solvents causes problems such as alteration of aroma or heterogeneity of aroma due to the extraction of miscellaneous components other than desired aroma components. In particular, this problem becomes an important obstacle in the production of so-called concentrated type of soup stock. That is, when a large amount of water is used to extract the aromatic components of the fruit, a larger amount of energy is required for concentrating it, and the loss of the aromatic components increases accordingly. Further, since concentrated type dashi is often used after being diluted, alteration or heterogeneity of the aroma as in organic solvent extraction methods deteriorates the quality of the dashi itself. In view of the above-mentioned current situation, the present inventors have conducted extensive research in order to develop a new method for easily and efficiently collecting the aromatic components of knotweed. The present invention was completed based on the discovery that the yield and concentration can be significantly improved by recovering the aroma component. The present invention uses, as a raw material, a residue obtained by extracting flavor components and part of aroma components from knots or knots by water extraction, when extracting and separating aroma components in knots.
A method of separating and collecting aromatic components by adding water to the mixture and performing heating and evaporation at the same time to transfer the aromatic components to the distillation section, concentrating and recovering the distillation section. This applies to Although the present invention is a simple method, it does not use organic solvents, adds only a small amount of water, and has the unique ability to separate and collect aromatic components while minimizing energy loss and dissipation of aromatic components. It is effective. As the knots of the present invention, knots such as bonito flakes, Sota flakes, and mackerel flakes, or kezuri flakes are used singly or in combination of two or more. As the extraction material, these knots themselves or the extraction residue obtained by subjecting these knots to hot water extraction or the like can be used. In the present invention, water is added to the extraction material to perform extraction and evaporation at the same time. In this case, the amount of water added is 2 to 100 times the weight of the extraction material, preferably 5 to 20 times the weight of the extraction material. be. In other words, if the amount of water added is too small, extraction will not be carried out sufficiently, but if it is too large, not only will concentration require a large amount of energy, but it will also involve loss of aroma components due to scattering, etc. This makes it impossible to hope for the purpose of the present invention to be achieved. Therefore, the optimum range is 2 to 100 times the weight, preferably 5 to 20 times the weight. The temperature of extraction and evaporation is not particularly limited, but it is usually carried out at 50 to 105°C, preferably 80 to 100°C. The pressure in this case is adjusted to be equal to the vapor pressure of the extract at the extraction temperature. Incidentally, the evaporation is preferably carried out while stirring, and the water may be continuously replenished or the insufficient amount may be added from time to time. The evaporated water vapor containing aroma components is used after being liquefied, but after condensing the entire amount, in order to further increase the concentration of aroma components, partial condensation or rectification may be performed and the liquid may be collected. The present invention will be further explained below with reference to Examples. Example 1 Hot water at about 90℃ to 10g each of Aragame Bushi powder and Soda Bushi powder
200 cm 3 was added, and extraction and evaporation were performed simultaneously under normal pressure using a rotary evaporator. At this time, the liquid volume decreases due to evaporation, but the liquid volume is 150 cm 3
When the temperature reaches 100°F, hot water is replenished, and the steam temperature reaches approximately 11°C.
The mixture was cooled and condensed with water, followed by extraction and evaporation until 600 cm 3 of distillate was obtained. On the other hand, as a control, using 800 cm 3 of water, 20 g of the above Seiko mixture was extracted and filtered with hot water, and the dashi extract was
Obtained 770cm3 . When we compared the aromas of the two, we found that the distillate obtained by the method of the present invention had a much stronger aroma than the control, and when the distillate was diluted with water, it had the same strength as the control dashi extract. The dilution factor was 5 times. From the above results, it was found that the method of the present invention not only produced a highly concentrated bonito aroma component extract with five times the aroma concentration, but also increased the yield by about five times. Example 2 Extract 5 kg of Honbushi flour with 15 kg of hot water at 95°C, separate the extract liquid by centrifugal filtration, and obtain 6.2 kg of single-stage extraction lees.
I got it. Add 15 kg of hot water to this single-stage extraction lees, and use 14.6 kg of the extracted and separated liquid to extract 5 kg of Honbushi powder.
Then, centrifugation was performed to obtain 13.2 kg of second-stage extract and 6.2 kg of second-stage extracted lees. Add 93 g of water to 3.1 kg of this two-stage extracted lees,
Evaporate and condense at a vacuum of 350 Torr and a temperature of approximately 80°C at an evaporation rate of approximately 20 kg/H to obtain a separated aroma component liquid.
Got 70. As a control, 93 hot water was added to 3.1 kg of the above-mentioned two-stage extracted lees and extracted and separated to obtain an extract 92. A fragrance component separated liquid obtained by the method of the present invention,
When comparing the aroma titer with a control extract using the dilution method, the aroma of the separated solution of the present invention was approximately 4.
It was confirmed that it is twice as strong. In addition, the separated liquid of the present invention and the control extract were added and mixed in the above-obtained quantitative ratio to the above-mentioned two-stage extract in which some of the taste components and aroma components were dissolved, as aroma reinforcement. , a sensory evaluation was conducted. Results first
