Abstract

SILVA, Priscilla Andrade; ASSIS, Glaucy Takeda; CARVALHO, Ana Vânia  and  SIMOES, Marilda Garcia. Development and characterization of an extruded breakfast cereal from cassava enriched with milk whey protein concentrate. Braz. J. Food Technol. [online]. 2011, vol.14, n.4, pp. 260-266.

The objective of this study was to develop and characterize an extruded cassava breakfast cereal enriched with milk whey protein concentrate. The extruded product was formulated by adding 15% of milk whey protein concentrate to cassava flour. The raw materials and the cassava flour breakfast cereal obtained were analyzed for their physicochemical characteristics. The breakfast cereal was also evaluated for its microbiological and sensory characteristics. The extruded product presented an expansion index of 11.49 and apparent density of 0.21g.cm-3. With respect to the sensory analysis, the breakfast cereal obtained hedonic ratings in the range from 7.63 to 8.05 for all the attributes evaluated, corresponding to the categories "I liked moderately" and "I liked a lot". For purchase intention, 91.70% of the panelists said they certainly or possibly would buy the product. The use of cassava and milk whey protein concentrate represents an alternative for the production of an extruded breakfast cereal with good sensory and nutritional characteristics.
