them is using formaldehyde as preservative, formal
in itself is prohibited in food. The content of
saponin compounds in key meeting is able to reduce formaldehyde in white tofu. So that in this study
using key analysis to reduce levels of formaldehyde.
Purpose:

levels
in white tofu samples using a solution of temu Kunci with various concentrations and
