Abstract

Soymilk processed with six different coagulants (CaCl , MgCl , CaSO , MgSO , alum and steep water from a local pap producing industry) were investigated for the effects of coagulating agents on the percentage yield, mineral and vitamin composition of tofu produced. The percentage yields (57.13 - 70.10%)
across treatments were significantly different (P<0>K>Ca>Mn>Cu>Zn>Fe>Na>Al>Se>Co in most of the samples. Heavy metals like Pb, As and Cd were not detected in any of the tofu samples analysed. beta-carotene (175.98-278.04 mg/100gDW), Vitamin E (43.69-68.44 mg/100gDW), Vitamin B (1.48-3.02 mg/100gDW) and Vitamin B (0.12-0.31 mg/100gDW) were also obtained in the tofu samples. Results suggested that these coagulants modulate the percentage yield, mineral and vitamin compositions of tofu samples produced. All tofu samples analysed were relatively high in micronutrient content, irrespective of the coagulant. However, MgSO seemed to be the best coagulant, in terms of the micronutrient content.
