Resumen/Descripción – provisto por el repositorio digital
The objetive of this work were: a) to study on the first instance the effect of the combination of reducing and oxidant additives on the specif volumen of mold bread, using as oxidant agents Ascorbic Acid and Azodicarbonamide (ADA), and as reducing agents Cysteine and Bisulfite of Sodium b) To get better, on a second part, the utilization of the combination of select additives to improve the quality of mold bread with flours of weak tecnological characteristcs, called flours A, B y C. Flour A with weak tecnological characteristics and Flour C stronger than others. Essays of panification were made on mold bread with different combination additives. These additives were used in combination of pairs in two levels of concentration. It was done an analysis of variance using the the test of multiple range in order to value the different statistician and through the variation of coefficient it was done the measure of dispersion The use of oxidanting-reducing pairs had a better efficience in the case of weak flours.The combinations more important Ascorbic Acid-Bisulfite of Sodium and Azodicarbonamide-Bisulfite of sodium. Ond a second step it was proceed to get the best in the oxidanting-reducing leveles in order to improve the quality of mold bread with a flavour of weak tecnological characteristics. For each combination Ascorbic Acide-Bisulfite and ADA-Bisulfite were done twenty expeiences where it was determined the consistency of the mass, specif volume, total score and texture in the day number: zero, three and seven.
