Extraction method of effective component of acorn and non-alcoholic beverage comprising the effective component of acorn

摘要

The present invention is an active ingredient extraction method acorn to extract effectively especially obesity control substance as an active ingredient of the acorn and relates to a beverage containing an effective ingredient an extract of acorn, the active ingredient extraction method of the acorn according to the invention, (1) the drying step of drying the acorn, without removing the endothelium; And (2), but the extraction condition for the extraction temperature to 37 to 67 ℃, 1 the extraction time to 4.5 hours and the solvent ratio with respect to the dried acorn 100 parts by weight of extraction into water of 6 to 24 times the weight of the acorn, antioxidant the extraction conditions in order to effect 37 to 61 ℃, put the extraction time 1 to 4.5 hours and the solvent ratio to 6 to 24 times of water of the hot water extraction, or extraction conditions in order to increase the gallic acid content of 65 to 67 ℃, extraction for a time from 1.5 to 2.0 times and a non-solvent hot water extraction step for extracting hot water into the water 17 to 18 times of the weight of the acorn; including features a true. ; Acorn, extraction conditions, obesity control, extraction temperature, extraction time, solvent ratio, electron donating
