Effects of the temperature on the quality of stored black gram sprouts (Phaseolus mungo L.).


Black gram sprouts packed in laminated pouches (205 grams each) were purchased from a retail market and stored at 4, 20 or 30 deg C for 9, 4 or 3 days, respectively. During storage, the relative humidity in each pouch was 80-100%. The CO2 concentration in the pouches was almost constant at 15% with 4 deg C storage. A weight reduction caused by drip loss was observed. The number of aerobic bacteria measured by the most-probable-number method increased during storage, but was still below 100 millions cells/gram in the worst case. The total vitamin C content measured by high-performance liquid chromatography was greatly affected by the storage temperature. A sensory evaluation panel judged the sprouts by odor, appearance and finger touch to be edible after as long as 8.7 days storage at 4 deg C, 1.9 days at 20 deg C and 0.8 days at 30 deg C.
