WANG, Sin-Huei; CABRAL, Lair Chaves  e  BORGES, Geraldo Gonçalves. Utilization of soymilk residue in preparing "paçoca" . Pesq. agropec. bras. [online]. 1999, vol.34, n.7, pp. 1305-1311. ISSN 1678-3921.  http://dx.doi.org/10.1590/S0100-204X1999000700024.

The objective of the present study was to utilize the soymilk residue (SR), wheat flour and peanuts to formulate "paçoca" of good protein quality and also good sensory characteristics. The 40% of roasted wheat flour were mixed with 30:0 (I); 25:5 (II); 20:10 (III); 15:15 (IV); 10:20 (V) and 5:25 (VI) of dehulled and roasted peanut flours and SR, respectively, to prepare the above mentioned products. It was verified, with the use of chemical analyses, that the ether extract content decreased from 19.54 to 11.51%, whereas the ash, fiber and carbohydrate contents increased from 0.99 to 1.23%, from 1.56 to 5.08 and from 56.06 to 61.40%, respectively, with an increase of the proportion of SR. On the other hand, the protein content was not affected. The essential aminoacids profile was improved with an increase of the proportion of SR. Results of sensory evaluation indicate that mixtures with up to 15% of SR showed good characteristics of appearance, flavor and texture, a mixture with 10% of SR being preferred by non-trained panelists.
