Abstract

The invention belongs to the field of plant extraction and particularly relates to a separation method for coproducing macadimia nut polysaccharide and albumen. The method mainly comprises the following steps: extracting macadimia nut grease at low temperature by using a supercritical or subcritical solvent; then, soaking oil meal by using alkaline water; filtering or centrifugalizing the obtained homogenate to remove impurities; adjusting the pH to a protein isoelectric point; then, centrifugalizing to obtain a precipitate which is coarse albumen; then, after repeatedly washing by using a precipitate solvent, carrying out low-temperature spraying and drying to obtain the macadimia nut albumen; and carrying out steps such as concentration, spraying and drying on the supernate to produce macadimia nut polysaccharide. The production process is continuous and compact, easy to implement, and high in technical raw material utilization ratio, product yield and purity.

Description

technical field

[0001] The invention belongs to the field of plant extraction, and in particular relates to a separation method for co-producing macadamia nut polysaccharide and protein. Background technique

[0002] Macadamia ternifolia F.Muell is a dicotyledonous evergreen tree of the Proteaceae family (Proteaceae), native to the subtropical rainforests of Queensland and New South Wales, Australia. Its nuts have high oil content and unique functions, and are known as the "Queen of Dried Fruits". In addition to being mainly used as dried fruit, nuts are used in some cosmetics, health care products because of their high oil content (about 80% of the weight of the nuts), and their nutritional and health effects such as anti-oxidation, prevention and reduction of cardiovascular diseases. It plays an irreplaceable role in food and other industries, so there is still a certain amount of macadamia nuts used for oil processing every year.
