Pilot-Scale Protein Recovery from Cold-Pressed Rapeseed Press Cake: Influence of Solids Recirculation
نویسندگان
چکیده
The agricultural sector is responsible for about 30% of greenhouse gas emissions, and thus there a need to develop new plant-based proteins with lower climate impact. Rapeseed press cake, by-product from rapeseed oil production, contains high-quality protein. purpose this study was recover protein cold-pressed cakes on pilot scale using decanter investigate the effect recirculation spent solids fraction yield. Proteins were extracted under alkaline conditions (pH 10.5) followed by precipitation at pH 3.5. Recirculating once increased accumulated yield 70% 83%. efficiency recovery process highest in first second cycles. additional after third fourth cycles only 2%. amino acid composition showed high levels essential acids not reduced throughout process. glucosinolate phytate content precipitate one cycle, although steps are needed further reduce limit negative mineral uptake.

Rapeseed and rapeseed press cake were tested in four long-term experiments with a total of ninety-eight pigs. Rapeseed contained 20 and rapeseed press cake 19 mmol glucosinolates/kg DM. The proportion of the tested rapeseed products in feed amounted to 0 (control), 50, 100 and 150 g/kg diet. Moist-heat-treated rapeseed and rapeseed press cake with an extremely low glucosinolate content were als...
متن کاملProcessing conditions affect nutrient digestibility of cold-pressed canola cake for grower pigs.
Cold-pressed canola cake is a coproduct of biodiesel production that contains more residual oil than expeller-pressed and solvent-extracted canola meal. Cold-pressed canola cake might be an attractive feedstuff for swine due to local availability from small plants. However, the nutritional quality and content of anti-nutritional factors of cold-pressed canola cake are poorly defined and vary wi...
متن کاملCold-pressed and hot-pressed rapeseed oil: The effects of roasting and seed moisture on the antioxi- dant activity, canolol, and tocopherol level.
BACKGROUND The paper looks at the levels of canolol, tocopherols and antioxidant activity in cold-pressed and hot-pressed rapeseed oils produced from seeds of various moisture levels (5%, 7.5%, and 10%). The paper also considers the effects of seed roasting on the levels of these compounds. METHODS The material used for the tests was rapeseed cv. Adrianna. The quality of the oils obtained is ...
