The main components of food garbage were rice, meat and
vegetables, which were used as the test materials. The
maximum proportions of food garbage disposal in Japan
are rice 12 %, meat 13 % and vegetables 75 % (radishes
25 %, carrots 25 %, apples 15 % and cabbages 10 %). The
mixtures of food garbage containing about 83 % moisture
content were freeze dried at -80 C and then pulverized
thoroughly to prepare model food garbage with model
compounds.
