Research Progress On Extraction And Bioactivity Of Melanin From Marine Cephalopod Ink, Xie Jing-Wen, Yang Xi-Hong, Che Hong-Xia, Zhang Jing-Yu, Yu Dong-Xing, Xie Wan-Cui
Food and Machinery
Based on molecular structure and physical and chemical properties, we compare the characteristics of melanin separation and purification by different methods, and summarizes the antioxidation, immunomodulation, radiation protection, antiviral, chelated metal ions, antitumor, organ protection, anti-inflammatory and antibacterial properties of melanin. Biological activities, such as DNA protection, focus on the characteristics and mechanisms of antioxidant, metal chelation, anti-tumor, and radiation protection, and provide guidance for the higher value utilization of melanin.

Research On Ultrasonic-Assisted Extraction Process And Stability Of Polysaccharides From Lilium Davidii Var Bulb, Li Gang-Gang, Sun Jing, Fu Heng-Yi, Xiao Bi-Liang
Food and Machinery
An orthogonal test was utilized to optimize the ultrasonic-assisted extraction process of polysaccharides from Lilium davidii var waste bulb, and the stability of the polysaccharides was studied. The results showed that the optimum extraction conditions for ultrasonic-assisted extraction process were as followed: the ratio solid to liquid of 1:20 (g/mL), ultrasonic time of 60 min, ultrasonic power 250 W, and ultrasonic temperature 60 ℃. Under the conditions, the extracting rate of polysaccharides from Lilium davidii var was 18.44%. The anti-oxidization stability of polysaccharide extracts was poor, whicht was easy to be oxidized by H2O2, but has …
