Title
(DE) REINIGUNG VON RUBISCO-PROTEIN AUS PFLANZEN
(EN) PLANT-DERIVED RUBISCO PROTEIN PURIFICATION
(FR) PURIFICATION DE PROTÉINES RUBISCO DÉRIVÉES DE PLANTES
Abstract
(EN) The disclosure describes methods for the purification of protein- enriched extracts to provide concentrates and isolates and methods for incorporation of such materials into products. The purification methods are adapted for removal of, e.g., chlorophyll and may thus provide lightening the color of the protein-enriched extracts. The methods generally include treatment with peracetic acid and filtrations. A protein composition in the form of a concentrate or isolate is provided, the protein composition including RuBisCO, F2 fraction proteins, or combination thereof extracted from a plant material.
(FR) L'invention concerne des procédés de purification d'extraits enrichis en protéines permettant de fournir des concentrés et des isolats, et des procédés d'incorporation de tels matériaux dans des produits. Les procédés de purification sont adaptés à l’élimination, par exemple, de la chlorophylle et peuvent ainsi permettre d'éclaircir la couleur des extraits enrichis en protéines. Les procédés comprennent généralement un traitement à l’aide d'acide peracétique et des filtrations. L'invention concerne une composition de protéine sous la forme d'un concentré ou d'un isolat, la composition de protéine comprenant RuBisCO, des protéines de fraction F2, ou une combinaison associée extraites d'un matériau végétal.
