PURPOSE:To obtain an excellent oxidation-resistant substance by a simple process inexpensively by using edible plant seed lees with an oil content of a specified value or smaller as a raw material, performing heat treatment thereof while temp. and time and controlled, and extracting it with an org.solvent. CONSTITUTION:Edible plant seed lees which are dregs obtd. by extracting an edible oil, coffee, etc., from an edible plant seed such as a sesame, a rapeseed, a soybeen or a coffee bean and having an oil content of 5 wt.% or lower are prepd. as a raw material. After these lees are heat-treated at 160 deg.C or higher for 20 min or longer, they are extracted with an org. solvent (e.g. ethanol or ethyl acetate) and the solvent is removed from the extract to obtain an oxidation-resistant substance. The obtd. substance is used suitably as an antioxidant for not only various foods and beverages but also chemical products such as plastics and petroleum products such as an engine oil. |
