(EN) PROCESS FOR PRODUCING PACKAGING SYSTEM FOR BANANAS WITH BIOCHAR-BASED ETHYLENE ADSORBER

The present utility model relates to a process for producing a packaging system for bananas incorporating a biochar-based ethylene adsorber to delay ripening. The process comprises
providing a biochar material selected from carbonized rice hull or activated carbon; packaging the biochar material into a perforated polypropylene sachet; packaging a banana product into a primary polypropylene packaging; inserting the packaged biochar material into the primary packaging; and sealing the primary packaging. The primary packaging may have a thickness of about 20 microns and dimensions of about 380 mm × 260 mm, while the sachet may have a thickness of about 25 microns, an average perforation diameter of about 1 mm, and about 1,064 perforations.  The carbonized rice hull may have a bulk density of 0.15–0.19 g/ml and a moisture content of 3.3–3.8%. The process produces a packaging system that adsorbs ethylene, maintaining peel greenness and extending banana storage life.
