Abstract
|
|
|
|
Demineralization (DM) from crab shell (CS) waste was carried out using a lactic acid-producing bacterium, Lactobacillus paracasei subsp. tolerans KCTC-3074 for 7 days at 25, 30, and 35°C. DM rates were 89∼92% and slightly affected by temperature. DM was also performed for four particle-sized shell samples (0.84∼3.35, 3.35∼10, 10∼20, and 20∼35 mm) with 10% inoculum, 5% shell, and 10% glucose at 30°C and 180 rpm for 7 days. It was found out that the shell size had a slight effect on the rate of DM. Negative relationships were found between DM and residual dry weight (r2 = 0.960), and between DM and pH (r2 = 0.906). Conversely, positive relationships were found between DM and medium protein (r2 = 0.696), and between DM and total titratable acidity (r2 = 0.630).
