Ultrasound-Assisted Enzymatic Extraction Of Polysaccharides From Corn Bran And Determination Of Their Antioxidant Activity, Ma Li-Yuan, Huang Xue-Ying, Shang Er-Kun, Guo Li, Zhang Ya-Na
Food and Machinery
Obiective: In the study, corn bran powder was used as raw material, and the cell wall was destroyed by ultrasonic vibration and enzymatic hydrolysis, so that corn bran polysaccharide could be dissolved more fully. Methods: The extracted amount of polysaccharide was taken as the index, response surface test optimization was carried out on the basis of single factor test. And the antioxidant activity of corn bran polysaccharide was determined. Results: The optimal extraction process of corn bran polysaccharide was obtained as follows: mass ratio of cellulase to pectinase 2∶1, enzyme dosage was 2% of the quality of corn bran powder, …

Food and Machinery
The effect of 60Co-γ ray irradiation on hypoglycemic activity of polysaccharides from Inonotus obliquus was explored. The polysaccharides of Inonotus obliquus under the irradiation doses of 5, 10, 20 and 30 kGy were extracted and their contents were determined. The experiment was performed on a mouse model of type I diabetes induced by streptozotocin (STZ) according to the grouping dose. The body weight, food intake and water intake of the mice were measured every day during the experiment, blood glucose levels were measured every 7 days, and glucose tolerance test (OGTT) was performed 30 days later. Blood samples were …

Analysis Of Pyrolytic Properties Of Polysaccharides And Its Application In Cigarette, Huan Liu, Gui-Lin Chu, Li He, Jie-Lun Hu, Hai-Tao Luo
Food and Machinery
The types of polysaccharides that have been used in the research on moisturizing and flavoring of cigarettes are summarized. The types of pyrolysis products, pyrolysis mechanism, and the law of influence on cigarette moisturizing, flavor enhancement, and mainstream smoke are described in detail from the two aspects of cigarettes' own polysaccharides and externally added polysaccharides. The direction for future development is proposed.
