Assessment of Soaking Solutions for Oxalate Reduction in Locally Known “Galyang” Collected from Cauayan City, Philippines

This study examined the effects of household processing methods on the oxalate content of a locally sourced “Galyang,” a taro-type plant collected from Barangay Marabulig I, Cauayan City, Isabela. The study was anchored on the principle of oxidation-reduction reactions used in permanganometric titration for oxalate determination. A two-factor Completely Randomized Design (CRD) with subsampling was employed to evaluate oxalate reduction between raw and processed samples. Young leaves, stalks, and
