Enzymatic Breaking-Extraction And Characterization Of Protein From Rape Bee Pollen, Wang Ling-Bo, Zhu Song, Chen Shang-Wei Jun 2020

Enzymatic Breaking-Extraction And Characterization Of Protein From Rape Bee Pollen, Wang Ling-Bo, Zhu Song, Chen Shang-Wei

Food and Machinery

The bee pollen of oilseed rape was used to investigate the effect of enzymatically breaking the wall for protein extraction, and the optimal conditions of the extraction were determined by single factor test and response surface analysis. After mixing 2.5


Effect Of Pecan Variety And The Method Of Extraction On The Antimicrobial Activity Of Pecan Shell Extracts Against Different Foodborne Pathogens And Their Efficacy On Food Matrices, Veerachandra K. Yemmireddy, Cameron Cason, Juan Moreira, Achyut Adhikari Jun 2020

Effect Of Pecan Variety And The Method Of Extraction On The Antimicrobial Activity Of Pecan Shell Extracts Against Different Foodborne Pathogens And Their Efficacy On Food Matrices, Veerachandra K. Yemmireddy, Cameron Cason, Juan Moreira, Achyut Adhikari

The shells of pecans are a rich source of bioactive compounds with potential inhibitory activity against various pathogenic microorganisms. This study investigated the antimicrobial activity of pecan shell extracts as effected by the type of cultivar and the method of extraction against various foodborne bacterial pathogens. Defatted shell powders of 19 different pecan cultivars were subjected to aqueous and ethanolic extraction (1:20 w/v) procedures, respectively. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of lyophilized pecan shell extracts dissolved in deionized water containing 5% DMSO (v/v) were determined against multiple strains of Listeria monocytogenes, Salmonella enterica, and …


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 Apr 2020

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 Mar 2020

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 …


Characterization And Analysis Of Curcumin Extracted From Turmeric Using Mass Spectrometry And Uv-Vis Spectroscopy, Cecilia Russo, Anna Fedor Jan 2020

Characterization And Analysis Of Curcumin Extracted From Turmeric Using Mass Spectrometry And Uv-Vis Spectroscopy, Cecilia Russo, Anna Fedor

Student Research Poster Presentations 2020

Turmeric is a spice most commonly found in Indian cuisine that is known for its medicinal properties. The most active compound that can be found in turmeric is curcumin. Curcumin is a polyphenol that is best known for its antioxidant and anticancer properties. Curcumin is mostly insoluble in water so the extraction of curcumin from turmeric was achieved by using ethanol or dichloromethane/hexane as the solvent. Since turmeric is not soluble in these solvents, a small amount of turmeric was soaked in larger amount of ethanol or dichloromethane/hexane to allow the curcumin to be dissolved out. The resulting solution can …
