Abstract

Few studies have examined the effects on nutrient contents and organoleptic properties of substituting wheat flour by protein dense ingredients as are soy protein concentrate, oat and chia in bakery formulas. The objective of the study was to assess the effect of adding soy protein concentrate, oat and chia to two breadsticks formulas proposed to provide at least 10 % of the daily recommended value of protein for an adult. Thirty three percentage of wheat flour were substituted by 3:1 oat:chia (BO) and 1:1 oat:chia (BC) composite flours. The analyzed parameters were wheat-meal fermentation time, moisture, protein, insoluble and soluble dietary fiber, firmness, organoleptic acceptance, and preference. Results revealed that both formulas contributed the minimum wished protein content, had higher dietary fiber content than only wheat flour breadsticks and had an acceptable texture, flavor, and appearance. It is recommended to continue formula BO because it turned out to be the favorite in the preference test.
