PRODUCTION OF HIGH-QUALITY PROTEIN ISOLATES FROM DEFATTED MEALS OF BRASSICA SEEDS

摘要

The present invention provides a method for processing defatted oil seeds,comprising the steps of: (a) solubilizing at least a portion of the proteincontained in the oil seeds to produce suspended residual solids and a firstsolution comprising protein, phenolic-protein complexes, and free phenoliccompounds; (b) separating at least a portion of the free phenolic compoundsfrom the first solution and recovering a free phenolic reduced solution; and(c) treating the free phenolic reduced solution to precipitate at least aportion of the protein as a precipitated protein isolate and recovering atreated solution containing a soluble protein isolate. Novel protein productsare also disclosed. Food and drink products containing the novel proteinproducts are also disclosed.
