Abstract
The effects of material kinds and processing time on the nutritive contents of shochu condensed distiller soluble (SCDS) were investigated. Samples were collected one time per month from four different processing plants, which process shochu made from rice, barley, sweet potato and barley plus sweet potato, respectively. The nutritive contents of SCDS were different among raw materials. There were high crude protein content in SCDS made from rice and barley, and high energy content in SCDS made from sweet potato. When raw material was one kind, the contents of crude protein and nitrogen free extract in SCDS had fewer changes all the year round, but the variation of dry matter contents was large. In this case, confirming material kind and DM content could estimate relatively correct the nutritive contents. On the other hand, when raw materials were not one kind, the crude protein content of SCDS had a large variation in year-round. In this case, it would be necessary to confirm material kinds and analyze chemical composition. When SCDS is used as a material of fermented TMR, it suggest that its low pH value will have a positive effect on the fermentation, while high buffering capacity and high pentose ratio in total sugar will have a negative effect.
