TI  - Effects of molecular weight and concentration of arabinoxylans on the membrane 
      plugging.
PG  - 4996-5002
AB  - In this paper, arabinoxylans from wheat were isolated, purified, and degraded 
      into four fractions with different molecular weight. The distribution of particle 
      size was employed to evaluate the membrane plugging by beer. These arabinoxylans 
      fractions were added into arabinoxylan-free beer to investigate the effects of 
      molecular weight and concentration on the distribution of particle size in beer. 
      Results showed that the fraction of arabinoxylans retained by a 0.22-mum pore 
      size membrane was more easily affected by shearing and arabinoxylan concentration 
      than the fraction of arabinoxylans retained by a 0.45-mum membrane. The effects 
      of shearing, pH, and ethanol concentration of beer on the particle size 
      distribution of the highest molecular weight arabinoxylan fraction in beer were 
      also examined. General linear models (GLM) equations indicated that there was a 
      positive correlation between the particle size distributions of arabinoxylans and 
      shearing and ethanol content, while high molecular weight arabinoxylans particle 
      size retained by the 0.45-mum membrane was not significantly (p > 0.05) 
      influenced by pH value. Scanning electron microscope (SEM) photos showed that 
      membrane plugging was significantly affected by the molecular weight of the 
      arabinoxylans.
