Giant squid (Dosidicus gigas) flour is a valuable source of protein (80 %) of high quality and bioavailability. This marine ingredient has an important amino acid profile that could be combined with cereals to obtain bread of high biological value. The aim of this study was to replace conventional animal proteins (milk, egg and albumin) with giantsquid flour (GSF) for the elaboration of high quality nutritional bread as part of the School Breakfast Program (SBP). SBP usually offers two types of bread formulations: Formula A (wheat flour 45 %, yellow cornmeal 5.5 and pea flour 3 %, milk powder 1.4% and egg 7.5%) and Formula B (wheat flour 47 %, soy protein concentrate 2.4 % whole milk UHT 3%, albumin 1.3% and yellow cornmeal 6 %). In order to obtain the optimum level of GSF, the adequate taste and acceptability of the fortified bread three phases were conducted. The first one was to acquire different GSF percentage of substitutions. A sensory ranking test was performed to compare the different formulations. In the second one, all chosen formulations, according to the preference level, were analysed by Response Surface Methodology using Design Expert Version 10 software to determine the optimum mixture. A sensory ranking test and assessment of protein quality (amino acid scoring pattern and digestibility of proteins) were applied to the suggested formulations by the program. The last one was to make bread with the optimal GSF substitution adding to the two types of SBP formulations (Formula A and Formula B) and to develop a physical, chemical, sensory ranking and biological analysis. The optimal formulation was 12.6 % of GSF substitution. There was no statistically significant difference (p < 0.05) between both fortified formulations with GSF according to the taste and acceptability analysis, both receiving high level of acceptability. A true digestibility value of 77.9± 1.45 for Formulation A and 80.11 ± 2.85 for Formulation B. in addition to an increase of protein intake for Formula A (6.9 to 15.9 %) and Formula B (7.9 to 17.3 %) was observed by the fortified breads with GSF compared to the bread offered by SBP.
