Title:
ANTIMICROBIAL AGENT COMPRISING SHELL, CLEANING OF WATER USING THE ANTIMICROBIAL AGENT AND WASHING OF FIELD CROP USING THE ANTIMICROBIAL AGENT
Document Type and Number:
Japanese Patent JP3420129
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an antimicrobial agent capable of preventing food contamination by bacteria in the production industry of processed foods, the food service industry and at home and suitable for sterilization, disinfection and microbial removal in the medical industry and the medical welfare industry by heating and heating up shells in an inert gas atmosphere and baking the heated shells at a specific temperature.
SOLUTION: This antimicrobial agent is preferably obtained by placing pulverized shells in an autoclave equipped with a stirrer, heating the pulverized shells in an inert gas atmosphere while stirring the pulverized shells, keeping the pulverized shells at 700-2,500°C final ultimate temperature for ≥3 min, baking the pulverized shells, allowing the baked pulverized shells to cool in an inert atmosphere, then further finely pulverizing the resultant baked pulverized shells, classifying the finely pulverized shells and using the prepared fine powder as a powder having 100 μm maximum particle diameter. Otherwise, the baked shells can directly be used without pulverizing. The antimicrobial agent is preferably added in an amount of about 0.025 wt.% based on the weight of drinking water or other objects of sterilization thereto for use. Since the shell powder is a natural material, the antimicrobial agent is safe for human bodies without polluting the atmosphere, wastewater and soil at the time of disposal treatment.
