Oilseed sunflower is one of the major vegetable oil sources. The residue after the
extraction of oil (defatted meal, DM) contains a substantial amount of nutritious protein
which is recoverable by extraction and precipitation methods. For effective recovery of
the solid proteins from the solids-liquid suspension, it is imperative to have large
particles with a narrow spread in their size distribution and high solids concentration.
In this research, up to 97 % w/w and 65 % w/w of the proteins in the laboratory
and industrially defatted sunflower meals, respectively, were extracted using aqueous
alkaline solutions at pH 10.0. Up to 84 % of these soluble proteins were recovered as
solids when the pH was lowered from 10.0 to 4.0 (isoelecmc pH) using aqueous HCI
acid. The amount of proteins recovered as solids decreased with decreasing
concentrations of the acid. |
