Abstract :

Symplocos sumuntia leaves (SSL), a Chinese medicinal herb, has been used to deposit Hakka tofu in southern China. In order to evaluating SSL used as a natural tofu coagulant, we analyzed its main compounds and the quality of Hakka tofu. The results showed SSL were rich in organic acids and various metal ions, especially aluminum content of SSL was reached 23071.98 [+ or -] 11.19 mg/Kg which indicated the plant was an aluminum hyperaccumulator. Thus, effect of SSL' extracts on coagulating Hakka tofu might due to its high organic acid and aluminum ions. Compared with the commercially available lactone tofu and marinated tofu, Hakka tofu was characterized with higher fat content and elasticity, lower calcium content and containing multiple metal ions, especially excessive aluminum (191.77 [+ or -] 2.11 mg/Kg). These results showed extracts of SSL has potential to be a natural coagulant, but attention should be paid to excessive residual aluminum in the product.
