Application of new methodology to canola protein isolation

“…Rapeseed derived protein rich products can be prepared by various approaches including the protein micellation method (Ismond and Welsh, 1992), membrane separation technology (Ghodsvali et al, 2005), direct alkaline extraction (Tan et al, 2011) as well as other methods. The direct alkaline extraction is one of the most typical procedures for preparation of canola (rapeseed varieties) protein isolates with high protein yield (Tan et al, 2011).…”

Introduction. The objective of this work was comparative analysis of protein properties of main oil seeds, cultivated in Ukraine, notably rape, sunflower and soy.. Materials and methods.Tetrachimena piriformis (WH-14 strain) cultures were used for the determination of relative nutritive value and toxicity of the protein products. The emulsifying capacity of seed proteins were determined as maximum volumes of emulsified oil relatively to 1 g of proteins and foaming capacity as volume of foam, obtained at standard conditions relative to volume of protein suspension.Results and discussion. According to our data biological value of soy proteins were limited by sulfur containing amino acid methionin and cystin (2,1% from common amino acid content). There total content was only about 60% of FAO/WHO scale. Biological value of sunflower proteins was limited by three amino acidssulfur containing amino acids (1,6% of methionine and cysteine) and lysine (3,0% from common amino acid content). The contents of majority of indispensable amino acids in rape proteins are 8-57% higher than FAO/WHO scale. The exception are valin and isoleycin with 80-85% content. Score of sulfur containing amino acid was 157,1% from FAO/WHO scale. Isolated rape proteins had highest technological properties, their solubilities were 16,4 to 38,6% at different pH, water holding capacity − 211 %, oil binding capacity − 130 %, emulsifying capacity − 140 ml/g, and foaming capacity -122 %.Conclusions. Investigated protein isolates of oil seeds (soy, sunflower and rape) had no toxicity. Rape proteins isolate had the highest relative biological value and technological properties.
