2.6. Total expressible fluid (moisture and solid)
Total expressible fluid was calculated for PEF and water bath treated
samples using the method of Lee, Whiting, and Jenkins (1987).
Sample cubes (2×2×2 cm) were placed between pre dried and
weighed 7 cm Whatman filter paper, number 4 (Whatman International
Ltd., Maidstone, England), then compressed by 50% of their
height using an Instron Universal Testing machine (Model No. 5544,
Instron Corporation, High Wycombe, UK) fitted with a load cell of
500 N and flat faced compression head. The filter papers were
weighed to determine total expressible fluid, dried overnight in an
oven at 105 °C and re-weighed to calculate the % moisture and solids
