  • Can a press cake produce soy protein isolates from defatted soy flakes?
  • Jaramillo et al. (2014) included the novelty of using a press cake with high oil content. Ali et al. (2010) compared a process of electro acidification and membrane ultrafiltration with conventional isoelectric precipitation in order to obtain soy protein isolates from defatted soy flakes.
  • Should sunflower protein be used instead of soy?
  • An increased utilisation of sunflower protein instead of that of soy would benefit the European market, by reducing dependence on imports. It would also represent health benefits by avoiding allergenicity and antinutrients-related concerns. Nevertheless, in order to do so, several challenges must be overcome.
  • Does sunflower protein complies with FAO recommendations?
  • Sunflower protein composition complies with the FAO recommendations ( FAO/WHO/UNU, 2007 ), except for Lys content. The protein of soybean is characterised by elevated contents of Lys, Trp, Ile, Val and Thr. However, sulphur-containing amino acids are less than in rape protein, especially Met and Cys.
  • Do soybeans have antinutritional factors?
  • Soybeans also contain antinutritional factors. Trypsin inhibitors (Kunitz inhibitors and Bowman-Birk inhibitors) cause a decrease in nitrogen retention and an increase in metabolic nitrogen excretion in animals. Soybeans also contain Lectins (hemaglutinins).
