Rapeseed’s role as a sustainable and nutritious plant protein source

AI simplified

Abstract

Rapeseed proteins, particularly cruciferin and napin, exhibit a balanced amino acid profile and diverse functional properties.

  • Rapeseed proteins are valued for their potential as a plant-based protein source due to their balanced amino acid composition.
  • These proteins demonstrate functional properties such as emulsification, foaming, and gelling, which are important for food applications.
  • Challenges in extraction and isolation include retaining functionality while minimizing antinutritional compounds like glucosinolates and phytates.
  • Off-flavors, bitterness, and limited solubility currently hinder the widespread use of rapeseed proteins.
  • Novel extraction and modification techniques, including enzymatic and fermentation methods, may enhance protein functionality and improve flavor profiles.
  • There is potential for rapeseed protein applications beyond food, including use in biomedicine and materials science.
