¹⁾ PM-25: Storage at 25°C without pressure plate, PM-25P: Storage at 25°C with pressure plate, PM-4: Storage at 4°C without pressure plate, PM-4P: Storage at 4°C with pressure plate.
^A-E Values with different letter within a same row differ significantly by Duncan's multiple range test (p<0.05).
^a-d Values with different letter within a same column differ significantly by Duncan's multiple range test (p<0.05).
Values are means±SD (n=3).
