This research aimed to study effects of fermented whey on coagulation efficiency and physicochemical characteristics of tofu, compared to other acid coagulants (acetic acid and glucono-delta-lactone (GDL)) and salt coagulants (calcium sulfate and natural gypsum). A randomized block design with a single factor was used in this research. Fermented whey could be used as coagulant in tofu manufacturing. Physicochemical characteristics of tofu from fermented whey were not significantly difference compared to tofu from calcium salt and acid coagulants. Coagulation efficiencies (CF, TSIL TPR and TB~) of fermented whey are lower than that from calcium salt coagulants (calcium sulphate and natural gypsum).
