Protein and Polysaccharides Extraction from Discarded Asparagus Base
Description: Harvesting and packaging of fruits and vegetables often creates a by-product which is disposed of since it has no commercial value, but may be beneficial towards human health. Freshly harvested asparagus spears are cut into equal lengths before packaging, in which the bottom base is discarded. Up to 50% of the asparagus spear is discarded, which creates a significant amount of waste. Discarded asparagus bases are currently incorporated into manure as crop fertilizer since it has no market value. Asparagus by-products contain fibre compounds, and vitamins, which can be used in the design of functional foods. The food industry may generate more value for disposed food by repurposing them as ingredients in new food products. By evaluating the causes of food disposal, and repurposing these by-products, Canada’s agri-food sector can reduce its environmental footprint, reduce its overall food waste each year, and reduce the cost of manufacturing new food products.
