| Research Abstract |
The barley which was milled is expected to have the enzyme activity compared to the pressed and split barley from the milled 55-60 % grains, these were processed by heating. The barley milled 85 and 60% were used as the samples with the 90% milled rice as the reference, and was investigated the relationship between the production of sugars and the activity of endogenous enzyme of the barley. The starch degrading enzyme activity of the barley was much higher than that of rice and the mixed cooking of barley and rice had larger amount of sugars than that of each cooking. It was found that the degradation of starch by amylase caused the increase of glucose by glucosidase, as a result the amount of reducing sugar of the mixed cooked rice and barley increased. The sensory test revealed that the palatability of the mixed cooked rice and barley of 40% was better than those of cooked barley of 100%.
