Combining Native and Malted Triticale Flours in Biscuits: Nutritional and Technological Implications.

ABSTRACT: Triticale-based biscuits were formulated with increasing substitution levels (i.e., 0, 25, 50, 75, and 100% w/w) of malted triticale flour (MTF). The products were analyzed for technological and nutritional characteristics, including the evaluation of the in vitro starch digestion. The results indicated that the substitution of triticale flour with MTF increased (p < 0.05) the total dietary fiber and ash contents. Total starch decreased (p < 0.05) when the level of MTF increased in the formulation, causing an increase in reducing sugars and an increase in the starch hydrolysis index and in the in vitro predicted glycemic index (pGI). The hardness and spread ratio values of biscuits decreased (p < 0.05) with increasing levels of MTF in the recipe. The lightness of doughs and biscuits decreased (p < 0.05) with increasing MTF levels. Overall, MTF could be used to formulate biscuits with higher dietary fiber content than native triticale flour and a medium to high in vitro glycemic index value as a function of the substitution level.
