Sensory and texture properties of "chipá": Influence of ingredients and storage conditions of batter

Abstract

“Chipá” is a gluten-free bread made with cassava starch and cheese. Usually, the batter is baked immediately and the product is eaten warm. In this study, the effect of refrigeration and freezing of batter, and the role of cheese upon “chipás” prepared with cassava or corn starch were analyzed. This may offer alternatives to the storage of batter, and contribute to the knowledge of the effect of refrigeration and freezing of batter in gluten-free baking products. Texture and colour were analyzed in batter and baked products. Volume, sensory quality and <i>in vitro</i> starch digestibility of “chipás” were also determined. The refrigeration or freezing of batter turned darker mainly the baked products containing cheese, probably due to the Maillard reactions between proteins and products of lipid oxidation. The “chipá” made with cheese and cassava starch was bigger, softer and gummier than that prepared with corn starch, and these properties did not change when the batter was frozen. No differences were found in the <i>in vitro</i> starch digestibility of “chipás” due to the batter storage conditions. Cassava starch was more digestible than corn starch. Freezing would be a good alternative to storage the batter of cassava starch and cheese.
