<p>PURPOSE:To remove the astringency of persimmons by volatilizing gradually ethyl alcohol in a packaging atmosphere, and to preserve astringent persimmons for a long period by utilizing the gas permeability of a packaging material and by keeping the balance between oxygen and carbon dioxide gas in packaging material. CONSTITUTION:A carrier (silicic anhydride, calcium silicate, crystalline cellulose, copolymer of starch-sodium polyacrylate) or an agent obtained by blending a kind of ethyl alcohol selected from powdery ethyl alcohol and solid ethyl alcohol with at least one adsorbing substance selected from active carbon and zeolite is packed into a small bag such as paper/permeable film, etc. and sealed. The bag and astringent persimmons are put in a synthetic resin sheet or bag having an oxygen permeability of 1,000-5,000, a carbon dioxide gas permeability of 3,000-15,000, and ethyl alcohol permeability of 0.5-15cc/m<2>.24hr.atm and sealed.</p> |
