Definitions
- the present invention relates to an antifoaming agent for fermentation, and relates to an antifoaming agent for fermentation in which a diluent with water is excellent in high-temperature stability and excellent in antifoaming effect.
- an antifoaming agent of a type in which an alkylene oxide is added to fats and oils and polyhydric alcohols as raw materials has little inhibition on the fermenting organism, and exhibits excellent foam breaking and foam suppressing properties. It has been widely used.
- the antifoaming agent for fermentation is added as a diluted solution that is an aqueous solution or suspension having a uniform concentration to the fermentation system by diluting in advance.
- a sensor detects bubbles generated in the fermentation tank and the defoamer diluent from the storage tank to the fermentation tank through an automatic dropping device.
- the antifoaming agent for fermentation needs to show an effect at a fermentation temperature of 30 to 40 ° C, it often has a cloud point at a temperature 10 to 20 ° C lower than that, and is dissolved and mixed in water above the cloud point. Therefore, the diluted solution is prepared by cooling to below the cloud point and stirring. Therefore, dispersibility in water at an optimum temperature is required.
- the antifoam diluent is sterilized by heating in order to prevent microorganisms from entering the fermentation vessel, and then cooled to near the fermentation temperature before being added to the fermentation vessel. For this reason, the antifoaming agent is exposed to a temperature equal to or higher than the cloud point by heating in the sterilization process, so that the solubility in water is lowered, so that it precipitates in the lower layer part, or oil droplets are formed from the upper layer part to the middle layer part. Tend to form.
- the antifoaming agent for fermentation described in Patent Document 1 Japanese Patent Publication: JP-A-5-228308 is obtained by adding alkylene oxide to a mixture of fat and polyhydric alcohol. Since the addition amount is smaller than the addition amount of propylene oxide, oil droplets are formed when the antifoam diluent is heated.
- the antifoaming agent described in Patent Document 2 International Publication No. 97/00942 is a complex system of the above type of antifoaming agent and higher fatty acid, higher alcohol, etc., and affects the fermentation results.
- the antifoam diluent is heated, the solubility of higher fatty acids and higher alcohols, which are mixed components, is significantly reduced. It will form and a defoaming effect will fall.
- the antifoaming agent described in Patent Document 3 has the same basic structure as the above type of antifoaming agent, but the amount of ethylene oxide added is as follows. Since it is large relative to the amount of propylene oxide added, precipitation and oil droplets are less likely to occur during heat sterilization, but the defoaming effect is not sufficient.
- the antifoaming agent described in Patent Document 4 Japanese Patent Publication: JP-A-2001-178446
- the object of the present invention is excellent in dispersibility in water during preparation of an antifoaming agent dilution solution, and causes precipitation and oil droplets in the antifoaming agent dilution solution after the heat sterilization step. It is to provide an antifoaming agent for fermentation having a strong antifoaming effect when a diluent is added to foaming in the fermentation medium.
- the present inventors have determined that propylene oxide at a specific ratio in a mixture of fat and oil and glycerin or a propylene oxide adduct of glycerin (the number of moles of propylene oxide added is 1 to 4 mol). Was added, and then block addition of ethylene oxide and propylene oxide was performed, and it was found that a defoaming agent for fermentation having high dispersibility in water and excellent defoaming property was obtained, and the present invention was completed.
- the diluted solution does not cause precipitation after the heat sterilization step, and the temperature is reduced to the fermentation temperature and added as it is to the fermentation tank, so that bubbles are generated quickly and continuously. Can be suppressed. Therefore, the yield of the fermentation product per unit fermenter increases and the yield improves.
