| Outline of Final Research Achievements |
The biofunction of the 57-kD glutelin precursor (proglutelin) was investigated using the enzyme treatment protein concentrates of sake lees and rice from the brewing suitable rice "hanasayaka" which accumulated a proglutelin. In vitro lipid adsorption characteristics of “hanasayaka” were high, and it was shown that the proglutelin was broken down in artificial digestive juice by an electrophoretic analysis. The weight of mesentery white adipose tissue on the KK-Ay mice significantly decreased in the sake lees feed, and the lipid discharges of feces increased. In addition, blood sugar level significantly decreased in the rice protein concentrate feed. These results suggest that proglutelin shows lipid adsorption in the body, and they have resistant protein-like action.
