Patent

CA 2502380

The invention relates to a protein-containing preparation of plant origin, having significantly improved sensoric properties and optionally also nutritional and physiological properties and undiminished good technofunctional properties. Said preparation can be obtained by fermentation with a lactic acid bacterium and is suitable as a versatile food ingredient. It contains at least 60 % of protein of plant origin, in relation to the dry weight, a lacteous aroma corresponding to a quantity of at least 1 ppm diacetyl, and lactic acid. The invention also relates to a method for producing one such protein preparation, whereby a plant starting material containing at least 60 wt. % of plant protein, in relation to the dry weight of the material, is fermented in a manner known per se with a micro-organism producing a lactic acid in the presence of at least one nutrient source, nitrogen source and/or mineral source required for the micro-organism.

L'invention concerne une préparation contenant des protéines à base de plantes et présentant des propriétés sensorielles et éventuellement aussi physiologiques et nutritionnelles notablement améliorées, ses qualités fonctionnelles restant intactes. Cette préparation, qui est obtenue par fermentation d'une bactérie d'acide lactique, est adaptée comme complément alimentaire à applications multiples. Elle contient au moins 60 % de protéine d'origine végétale, relativement au poids à l'état sec, un arôme de type lactique correspondant à au moins 1 ppm de diacétyle, et un acide lactique. La présente invention porte également sur un procédé pour réaliser une telle préparation protéinique, ce procédé consistant à faire fermenter dans les conditions usuelles un extrait végétal contenant au moins 60 % en poids de protéine végétale, relativement au poids de la matière sèche, avec un micro-organisme produisant de l'acide lactique en présence d'une ou de plusieurs sources de substances nutritives, azotées et/ou minérales nécessaires au micro-organisme.
