Abstract
The potato protein was obtained as a by-product of the starch production from potato tuber. Its yield was about 0.23 per cent of fresh potatoes.
The nutritional values of this potato protein were researched for rats. It was found that the potato protein supplemented with a small amount of the herring milt protein gave a very good effect on the growth of young rats. This effect was due to the high contents of arginine and the appetite promoting properties attributable to the herring milt protein. It was also shown that adult rats could support themselves sufficiently with a diet containing potato protein as the single protein source.
