Incorporation of chia seeds (Salvia hispanica L.) in cereal flour mixtures: Rheology and quality of sliced bread

Abstract

Bread is a staple food in many countries of the world. The objective of this work was to include chia seeds (2-5%) in mixtures of wheat flour (71.5-81.5%), quinoa (5-10%) and cañihua (10-15%) to obtain the bread of mold. The flours were characterized by their rheological properties by means of amylography, farinography and extensography tests. The formulations allowed to increase the protein content (1.10-1.87%), fiber (0.45-3.35%) and reduce the carbohydrate content (2.95-10.7%) in mold which also underwent texture, color and sensory analysis. With the latter it was revealed that the highest scores regarding appearance, flavor, odor, texture and color were produced by including 2% of chia seeds in mixtures of quinoa flour (7.5%), cañihua (15%) and wheat (75.5%) (p<0.05).
