Abstract

LEONEL, M.; JACKEY, S.  and  CEREDA, M.P.. INDUSTRIAL PROCESSING OF CASSAVA AND SWEET POTATO STARCH - CASE STUDY. Ciênc. Tecnol. Aliment. [online]. 1998, vol.18, n.3, pp. 343-345. ISSN 1678-457X.  http://dx.doi.org/10.1590/S0101-20611998000300016.

Starch industries have great interest by new starch raw material. This work compared the industrial manufacture yield of cassava and sweet potato starch in a Brazilian company. The results showed that the commercial starch of sweet potato was in quality specification of Brazilian legislation. The solid fibrous residue generated during the processing contained 79,94 % starch and similar composition of the cassava residue. The industrial yield was higher in cassava processing (25%) than sweet potato (18,3%). The starch retention in the solid waste indicated an inefficient extraction process for two raw materials.

Keywords : processing; starch; yield; cassava; sweet potato.
