TLDR
In this article, a composite central rotatable design was used to study effects of pH (X1), meal-to-solvent ratio (X2) and concentration of SHMP (X3) on nitrogen extractability (Y1) and protein recovery (Y2).Abstract:
Total proteins of defatted low-mucilage flaxseed meals were isolated by extraction with aqueous sodium hexametaphosphate (SHMP). A composite central rotatable design was used to study effects of pH (X1), meal-to-solvent ratio (X2) and concentration of SHMP (X3) on nitrogen extractability (Y1) and protein recovery (Y2). Using RSM, quadratic polynomial equations were obtained for Y1 and Y2 by multiple regression analysis. All three variables significantly affected nitrogen solubility and protein extractability. The pH was the most effective factor and meal-to-solvent ratio was least. Verification experiments confirmed validity of predicted models. Stationary points for response surfaces were characterized as maxima and they were Y1=77.6% at X1= 8.90, X2= 1:33.6 and X3=2.75% and Y2=57.5% at X1=9.00, X2=1:33.3 and X3=2.85%, for nitrogen extractability and protein recovery, respectively.read more

Antioxidant and free radical-scavenging properties of ethanolic extracts of defatted borage (Borago officinalis L.) seeds
TL;DR: Borage meal exerted a concentration-dependent antioxidant activity in a meat model system, and the resulting extract inhibited 2-thiobarbituric acid-reactive substances (TBARS), hexanal and total volatile formation in meat by 26.5, 30.5 and 18.6%, respectively.
