The optimal combination of seed sprouting and extrusion processes reduces the energy, economic and labor costs of germination and decreases the loss of sprouted seed. To obtain sprouted seed, various pre-treatment methods were evaluated before the extrusion process. It was found that the optimal pre-treatment of seeds before sprouting is treatment with microwave radiation of 1400 W/dm 3 for 20 s or 3% hydrogen peroxide for 10 min. When using such treatment methods, not only microflora suppression but also activation of the feed seed sprouting process are provided. The first sprouts appear in 12 hours. In 60 hours, the amount of sprouted seeds reaches 70-90 %. The length of sprouts at this stage of germination is optimal for further processing and is from 5 to 25 mm.
