This study was carried out to evaluate the effects of amyloglucosidase, glucose oxidase, hemicellulase (mainly consist of endo-1,4-b-xylanase), cellulase, lipase, and the combination of phospholipase and hemicellulase (phospholipase ? hemicellulase) on the extensographic properties of dough and the quality characteristics of bread prepared from wheat meal. The enzymes were added separately in two different amounts. The addition of glucose oxidase (at 0.0003-0.001%) caused a significant decrease in the resistance to extension, ratio of resistance to extensibility and energy values of the wheat meal dough compared with the control dough. The addition of hemicellulase (at 0.001-0.005%) and phospholipase ? hemicellulase (at 0.0006-0.0009%) also improved the wheat meal dough rheology by reducing the resistance to extension and the ratio of resistance to extensibility. Glucose oxidase (at 0.0003-0.001%), hemicellulase (at 0.001-0.005%) and phospholipase ? hemicellulase (at 0.0006-0.0009%) addition improved the specific volume of wheat meal bread compared with the control bread. Increasing the dosage of glucose oxidase from 0.0003 to 0.001% caused a further increase in the specific volume of wheat meal bread. The addition of hemicellulase (at 0.001-0.005%) caused a significant decrease in the baking loss and an increase in the moisture content of wheat meal bread compared with the control bread. The addition of amyloglucosidase (at 0.000875-0.001%), lipase (at 0.0002-0.001%) and cellulase (at 0.0003-0.0005%) did not considerably affected the dough rheological and the quality characteristics of wheat meal bread.

Wheat flour, whole wheat flour, 25 and 50 % rye flour substituted wheat flour blends, 15 and 30 % wheat bran substituted wheat flour blends were supplemented with amyloglucosidase (at 0.000875 and 0.001 %), glucose oxidase (at 0.0003 and 0.001 %) and hemicellulase (at 0.001 and 0.005 %). The effects of enzymes on the extensographic properties of dough and quality characteristics of bread (specific volume, baking loss percentage and final moisture content) were studied. The interaction between type of flour/blend, type of enzyme and dosage of enzyme affected resistance to extension, extensibility and ratio of resistance to extensibility of doughs significantly. The interactions between type of flour/blend, type of enzyme and dosage of enzyme affected specific volume, baking loss percentage and final moisture content of breads significantly. The findings in this study indicated that enzymes can exhibit unexpected effects on dough and bread properties depending on type of flour and dosage of enzyme.

This study was carried out to determine the effects of some flax varieties on yield and yield components in Ankara ecological conditions in 2021. The study was established with 10 flax varieties 3 replications according to the Randomized Complete Block Design. In the study, plant height (cm), first branch height (cm), number of branches per plant (pieces), number of seeds in the capsule (seed capsule-1), 1000 seed weight (g), number of encapsulated branches per plant (pieces), oil yield (kg ha-1), protein ratio (kg ha-1) and seed yield (kg ha-1) traits were examined. As a result of the research; There were statistically significant differences at the level of 1% between varieties in terms of yield and yield components. In the study, the highest seed yield, oil yield and protein yield (1806 – 599.7 – 428.5 kg ha-1) were obtained from Clli-1412 variety.
