2.3.5. Leaching Study
Bigels were cut into disks (diameter: 20-mm; height: 3.2-mm) and weighed. The disk was then placed in-between a folded pre-weighed filter paper. A 200-g weight was placed on top of the disk for 30 min. At 30 min, the disk was weighed again to determine the total amount of liquid lost from the sample. The filter paper was allowed to sit out for 24 hours to allow for the evaporation of any leached water. The filter paper was then weighed again to determine the amount of soybean oil leached from the sample. The total amount of liquid lost from the disk was calculated using the following formula:
\begin{equation} \%\ Liquid\ Lost=\frac{Initial\ disk\ weight-Final\ disk\ weight}{\text{Initial\ disk\ weight}}\times 100\nonumber \\ \end{equation}
