<p>PURPOSE:To improve keeping quality of food without deterioration of antibacterial property by allowing zeolite powder or zeolite-like powder to adsorb a mildewproofing agent, reforming to the reformed zeolite, forming a film contained the reformed zeolite and packing food with the film. CONSTITUTION:The reformed zeolite is obtained by allowing natural zeolite powder, a synthetic zeolite powder or a zeolite-like body powder such as Oya- ishi powder to adsorb the mildewproofing agent. An organic nitrogen-sulfuric compd. such as methylthiazolon or 1,2-benzoisothiazoline-3-on is exemplified as the mildewproofing agent. The obtained reformed zeolite is mixed to polyolefine and so the film for food is made from the mixture. When fresh food is packed and enclosed with the film and even if the reformed zeolite adsorbs free water, the mildewproofing property of the film is more enhanced without deterioration. Thus the keeping quality of good is improved.</p> |
