微粒子濃度を５重量％、温度を２５℃とする。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail. In general, the zeta potential of the silica fine particles dispersed in the sol changes depending on the pH value of the sol.

In order for the silica sol of the present invention to effectively act as a sizing agent, a negative value having an absolute value of 35 mV in a pH range of 4 to 6 is required.
It is necessary to have the above zeta potential. The zeta potential can be measured by an ultrasonic zeta potential measuring device (for example, ESA8000 manufactured by Matec). As measurement conditions, the pH of the sample silica sol is adjusted to a predetermined value with a diluted hydrochloric acid aqueous solution in advance, the silica fine particle concentration of the sol is 5% by weight, and the temperature is 25 ° C.

ましい。[0008] The silica sol as a sizing agent according to the present invention has a negative zeta potential of silica fine particles in a pH range of 4 to 6 and an absolute value of 35 mV or more, and the absolute value is extremely large. On the other hand, the protein constituting the slag in the fermented liquid food has a negative zeta potential as a whole, but its absolute value is smaller than the slagging agent according to the present invention, and is about -5 mV. . The larger the difference in zeta potential between the protein and the sagging agent, the more likely the protein in the fermented liquid food will undergo heteroaggregation. In the present invention, since the zeta potential difference is a negative value of 30 mV or more, heteroaggregation occurs. The potential difference is preferably a negative value of 35 mV or more,
More preferably, the negative value is in the range of 35 to 70 mV. In addition, the silica sol of the scouring agent according to the present invention preferably has a SiO 2 concentration of 10 to 40% by weight.

It is suitable for use in washing down liquid foods that cause protein turbidity, such as alcoholic beverages such as wine, soy sauce, vinegar, and fruit juice. In the method for scraping fermented liquid food according to the present invention, the scumming agent is added to the fermented liquid food and stirred, whereby the protein turbid substance in the liquid food is immediately coagulated and settled. The coagulated sediment is separated by a usual method such as filtration. The amount of the sagging agent added to the liquid food varies depending on the amount of the protein turbid substance, but in the case of sake, it is usually 10% as a 30% by weight SiO 2 concentration sol.
2,000 ppm, preferably about 40-1000 ppm. In the method of the present invention, a flocculant for assisting the growth of agglomerates, for example, a protein such as gelatin or a soluble high-molecular substance such as polyvinylpyrrolidone, is added in addition to the sagging agent in the same manner as in the conventional case, and the flocculating effect is obtained. Can be further promoted.

【発明の効果】本発明の滓下げ剤は、表１の滓下げテス
トの結果から明らかなように、シリカ微粒子のゼーター
電位が負の値で絶対値が３５ｍＶ以上のシリカゾルであ
るため、ゼーター電位値が−３５ｍＶよりその絶対値で
小さい通常のシリカゾルに比較して滓下げ速度が早く、
滓下げに要する時間を短縮することができる。As is clear from the results of the scumming test of Table 1, the scumming agent of the present invention is a silica sol having a negative zeta potential of silica fine particles and an absolute value of 35 mV or more. The slag speed is faster than a normal silica sol whose value is smaller in absolute value than -35 mV,
The time required for slag removal can be reduced.
