Summary
This study investigates the application of supercritical CO2 as a non-thermal processing technique to lupin flour and lupin protein isolates, evaluating its effects on nutritional composition and functional properties. Supercritical CO2 treatment is of interest as a method to reduce antinutritional compounds — such as alkaloids — while preserving protein integrity, potentially enhancing the suitability of lupin-derived ingredients for human consumption. The findings are likely to inform food manufacturers on the feasibility of supercritical CO2 as an alternative to conventional debittering and extraction processes for legume-based ingredients.
UK applicability
Lupin is a candidate crop for UK protein diversification and features in discussions around domestic plant-based food ingredient supply; findings on supercritical CO2 processing could be relevant to UK food manufacturers developing legume-based protein products, though processing technology adoption would depend on capital investment and regulatory context.
Key measures
Protein content and solubility; antinutritional factor concentration (e.g. alkaloids, trypsin inhibitors); lipid profile; functional properties (e.g. water/oil holding capacity); particle size or structural indices
Outcomes reported
The study examined how supercritical CO2 treatment alters the functional, nutritional, and compositional properties of lupin flour and lupin protein isolates. Parameters likely assessed include protein solubility, antinutritional factors, lipid content, and structural characteristics before and after treatment.
