The article discusses the need to control the technological parameters of wheat germination. A method of intensification of this process is proposed by pretreatment of grain with ultrasonic effect using the ULTA-0.63 / 22-OL apparatus UZTA-0.63 / 22-OL, Biysk. We have evaluated various modes of ultrasonic processing of the grain and their effect on the germination energy and the total number of nested and sprouted grains. We have also conducted optimization of grain processing conditions during germination. Based on the technological capabilities of the device and the optimal modes of ultrasonic exposure, the following exposure parameters were determined: 340 W and 5 minutes of exposure (soft wheat grain) and 397 W and 6 minutes of exposure (grain of durum wheat). The authors note that the intensification of this process significantly depends on varieties and qualities of wheat grain, since the process is complex and depends on many parameters. The use of ultrasonic treatment allows intensifying the soaking process and reducing the duration of this technological operation up to 6 hours for both samples of grain of soft and durum wheat. At the same time, for the necessary moistening of the grain, a ratio of water and grain for 1: 1 is sufficient, since there were no significant differences in the intensity of grain moistening
