Title (EN) PRODUCTION OF CANOLA PROTEIN
(FR) PRODUCTION DE PROTÉINE DE COLZA
Abstract:
(EN) A canola protein isolate having a protein content of at least about 90 wt% ( N x 6.25), preferably at least about 100 wt%, and consisting predominantly of the 2S protein and substantially free from the 7S and 12S proteins is prepared. In one aspect, canola oil seed meal is extracted with aqueous protein solution at an elevated temperature to preferentially extract 2S protein from the meal to produce a canola protein solution containing predominantly 2S protein. The 2S canola protein is recovered as an isolate. In another aspect, canola oil seed meal is initially extracted with water to preferentially extract 7S and 12S canola proteins followed by extraction of the canola oil seed meal with aqueous saline solution to extract 2S protein from the meal. 2S canola protein isolate is recovered from the saline extract. In another aspect, the canola oil seed meal is extracted with aqueous saline solution to extract 2S, 7S and 12S proteins from the meal. The aqueous protein extract solution is heat treated at an elevated temperature to precipitate 7S and 12S proteins and leave a 2S protein solution from which the isolate may be recovered. In a further aspect, the aqueous protein solution is concentrated prior to the heat treatment.
(FR) La présente invention concerne la préparation d’un isolat de protéines de colza ayant une teneur en protéines d'au moins environ 90 % en poids (N x 6,25), de préférence d'au moins environ 100 % en poids et constitué principalement de la protéine 2S et pratiquement exempt des protéines 7S et 12S. Dans un aspect, on effectue une extraction de farine de graines de colza avec une solution aqueuse saline à haute température pour effectuer préférentiellement l'extraction de la protéine 2S de la farine pour produire une solution de protéines de colza contenant principalement la protéine 2S. On récupère la protéine de colza 2S sous forme d'un isolat. Dans un autre aspect, on effectue initialement une extraction de farine de graines de colza avec de l'eau pour effectuer préférentiellement une extraction des protéines de colza 7S et 12S suivie d'une extraction de la farine de graines de colza avec une solution aqueuse saline pour effectuer une extraction de la protéine 2S de la farine. On récupère un isolat de protéine de colza 2S à partir de l'extrait salé. Dans un autre aspect, on effectue une extraction de farine de graines de colza avec une solution aqueuse saline pour effectuer l'extraction des protéines 2S, 7S et 12S de la farine. On traite thermiquement la solution d'extrait aqueux de protéines à haute température pour faire précipiter les protéines 7S et 12S et laisser une solution de protéine 2S à partir de laquelle on peut récupérer l’isolat. Dans encore un autre aspect, on concentre la solution aqueuse de protéines avant le traitement thermique.
