FRESHNESS RETENTION OF BROCCOLI

摘要

PURPOSE:To keep the broccoli highly fresh and control the decrease in the freshness until the consumption by tight-packaging broccoli with films having fine pores and maintaining the oxygen and carbon dioxide concentrations in the pouches at specific concentrations. CONSTITUTION:Broccoli are tightly packaged with a monolayered or multilayered film which has fine pares of 100 to 300mu average diameter, oxygen and carbon dioxide permeability of 100 to 900 co/24hrs.atm per pores (oxygen carbon dioxide permeability of 1,000 to 5,000/m<2>.24hrs.atm at 23 deg.C) to keep the concentrations of oxygen and carbon dioxide in the pouch at 3 to 15% and 6 to 18%, respectively.
