Protein preparations from rapse processing waste: A review of the current status and development prospects of existing technologies

The demand for protein products is increasing due to the demographic growth of world’s population. As an alternative traditional sources protein, waste from plant raw material processing becoming increasingly popular. An important place in global economy occupied by oilseeds, particular rapeseed, which production volumes are Russian Federation every year. Rapeseed ( Brassicaceae napus ) great interest its high oil content (39.80–46.00%) and rich fatty acid composition, while cake meal formed process characterized a significant crude (35.00–45.00%) fiber (8.20–17.50%); however, they used mainly as feed additive. Recent studies on rapeseed indicate value this source dietary has balanced amino profile degree digestibility (up 85%). To obtain envisaged: cleaning, grinding, cold pressing at temperature ≤ 40 °C, fat extraction with solvent. At next stages, extracted 0.1–0.5 M NaCl pH 5.3–12.0 5–30 °C 1 hour. precipitated isoelectric point (pH 4.0) HCl, separated mixture neutralized. result isolate 90.0–98.7%. It possible increase quality yield product additional stage defatted cellulolytic enzyme preparations. In case, required determine substrate specificity commercial cellulase preparations optimal hydrolysis conditions. parameters precipitation case using enzymatic lysis should also be specified.
