  • This study was performed to develop experimental model for milling degree and whiteness from analysis the CBB (colored bran balance) index using NMG dying and image processing. The endosperm layer increased and the pericarp, aleurone layer and CBB index decreased as the milling degree and whiteness increased. So, CBB index was closely linked to milling degree and whiteness. A empirical CBB index model was developed according to the milling degree and whiteness. The model were found to fit adequately to all test data with a coefficient of determination of 0.99, and therefore the CBB model proved to be quite applicable.

  • Clean rice is useful to save time and labor force against washing rice in the household. Nevertheless the quality characteristics of the rice were not established well since the quality characteristics of the rice depend on types of the processing system. The aims of the current study were to understand the quality characteristics of clean rice prepared from the dry, semi-dry, and wet types of processing systems, and to suggest the appropriate processing system for production of clean rice. Here, we found that the quality of clean rice was improved with the increasing whiteness of rice by the dry type, although the whiteness of rice should be below 42 to satisfy 16.0 NTU of the turbidity for higher head rice ratio. Also, both the semi-dry and wet type systems showed higher ratio of head rice than the dry type system at below 16.0 NTU of the turbidity. These results imply that the wet type is more suitable for the place where rice is consumed fast, and the semi-dry type is more proper for long term storage of rice.

  • This study was conducted to investigate the effects of Vaccinium uliginosum L. (bilberry) on chemically induced diabetes and hypercholesterolemia. Sprague Dawley (SD) rats were divided into six groups, control (CON), bilberry added group (CBB), streptozotocin (STZ)-induced diabetic group (STZ), STZ and bilberry added group (SBB), high fat fed group (HFF) and high fat and bilberry added group (HFB). Diabetes was chemically induced by intravenous injection of 45 mg/kg body weight STZ in citrate buffer (pH 4.5). Serum triglycerides decreased significantly (p<0.05) in the STZ group that was fed bilberry. Additionally, the athrogenic index (AI) decreased significantly (p<0.05) when compared to the STZ group, while the liver triglycerides tended to decrease in the STZ group. HDL-cholesterol also increased significantly in response to bilberry. When compared to the STZ group, steady attenuation of the blood glucose level was observed upon fasting, 15 min, 30 min, 60 min and 120 min after oral glucose administration. The blood glucose level in the bilberry fed group decreased by 24% when compared to STZ group, while the superoxide dismutase (SOD) became significantly higher (p<0.05) in the STZ group when compared to the CON group. Overall, the results of this study suggest that bilberry stimulates lipid metabolism in both the serum and liver and has a positive effect on glucose metabolism in chemically induced diabetic rats.
