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}
