Type of article: Article

Summary

SQUASH WAS STORED 2 WEEKS AT 275.5, 278, OR 283 K (2.5, 5 OR 10 DEG C) AND WITH 1,2, 4, 8, OR 21% O2 AND THEN WAS AERATED 2 DAYS AT 283 K. LOW O2 LEVELS INHIBITED THE RATES OF CO2 AND ETHYLENE PRODUCTION, PARTICULARLY AT 278 AND 283 K. ABOUT 75 AND 55%, RESPECTIVELY, OF THE BURST IN CO2 PRODUCTION IN SAMPLES FROM 275.5 AND 278 K WAS DUE TO EXPOSURE TO LOW TEMPERATURE AND THE REMAINDER TO THE EFFECT OF LOW O2 LEVELS. FOR ETHYLENE, THE CORRESPONDING VALUES WERE ABOUT 95 AND 70%. AT 278 K FOR 2 WEEKS SQUASH WAS VIRTUALLY FREE OF CHILLING INJURY, SURFACE MOLD, DECAY, OR OFF-FLAVORS AND DID NOT BENEFIT FROM STORAGE IN LOW O2 ATMOSPHERES. AT 275.5 K SEVERE CHILLING INJURY WAS INDUCED, WHICH WAS AMELIORATED BY HOLDING IN 4, 2, OR 1% O2. OFF-FLAVORS ARE DEVELOPED MOST NOTICEABLY AT 283 K. STORING AT 279 K (6 DEG C) + OR -2 K LIKELY WOULD BE OPTIMAL FOR LONGER THAN A FEW DAYS.
