Storage Cauliflowerswere stored for 9 wk in air or in N,,containing 3% O2 and 0, 2.5, 5 or 10% CO, at 1°C and 100% relative humidity, with or without pretreatment with 15% CO* Consumer visual acceptability and several maturity indicators (weight loss, rate of respiration, leakage of free a-amino compounds, levels of free sugars and organic acids) were determined. The samples exposed to 5% or less COz were still acceptable after 7 wk of storage, while 10% CO2 and pretreatment with 15% CO2 caused softening, yellowing and increased leakage. Respiration was decreased by low OZ. Increasing CO? up to 5% brought additional benefit. Succinic acid increased with increasing CO?.
Cauliflowersfrom the cultivar White Snowball wcrc stored for 9 weeks in air or Nz containing 3% O2 and 0, 2.5, 5 or IO% CO? at 1°C and 100% relative humidity with or without a 10 hr prctrcatmcnt with 15% C02. The heads wcrc kept in darkness in 30L containers under a continuous flow of the various atmospheres regulated at 3OL/ hr during the first 48 hr and later at ISWhr. The composition of the atmosphere in the containers was chcckcd daily.
