Chemical composition and nutritional value of protein concentrates isolated from potato (Solanum tuberosum L.) fruit juice by precipitation with ethanol or ferric chloride
Original language description
Effects of protein precipitators, ethanol and ferric chloride, on yield, re-solubility, chemical composition and nutritional values of protein concentrates isolated from industrial potato fruit juice (PFJ) were studied. Optimum precipitating concentrations of ethanol and ferric chloride in PFJ were 4 M (23.1% v/v) and 20 mM (2% w/v), resulting in yield of 69% and 89% of total protein, respectively. Contents of total glycoalkaloids and potassium in both protein concentrates were significantly lower (P <0.05) as compared with contents in PFJ dry matter. Both protein concentrates exhibited high nutritional value; values of essential amino acid index (EAAI) were 81.7% and 82.7%, respectively. Fraction of patatin proteins (39-43 kDa) represented with EAAIvalue of 86.1% the nutritiously improving protein component. Lipid acyl hydrolase (LAH) activity of patatin family was not negatively affected by ethanol precipitation suggested that biological and enzymatic activities of this protein fam
