In recent years, the demand of crucifers has increased and particularly of Brussels sprouts (Brassica genus, species Brassica oleracea L.); mainly due to their functional properties; however, this vegetable is perishable and with inadequate techniques in postharvest handling, considerable losses are generated. The objective of this research was to determine the effect of calcium chloride and cooling on postharvest behavior of Brussels sprouts. A completely randomized design was performed, treatments corresponded to three storage temperatures (4°C, 8°C and temperature (18°C)) and three concentrations of calcium chloride (0%, 2% and 4%) were used. Sprouts were harvested at commercial maturity on a farm irrigation district in Usochicamocha, Boyacá Department; of uniform size, excellent plant health and free from mechanical damage conditions. For 19 days of storage, weight loss, respiratory rate and total chlorophyll were measured. Sprouts stored at room temperature lasted 11days postharvest, while cooled lasted for 19 days. A significant effect in reducing weight loss between those sprouts which were stored at 4°C and 8°C and treated with calcium chloride solution at 4% was observed. For the respiratory rate was observed a significant reduction insprouts stored at 4°C. Therefore the most favorable temperature for the storage of Brussels sprouts is 4°C and calcium chloride solution 4%, useful information for producers and marketers.
