Dried and powdered leaves of parsley as a functional additive to wheat bread

Abstrakt

Parsley leaves (PL) are a rich source of many bioactive compounds and show many healthpromoting properties. The aim of this study is to analyze the effect of the addition of PL to wheat flour on the physical, antioxidant, and sensory properties of wheat bread. Wheat flour was partially substituted with 0, 1, 2, 3, 4, and 5% PL. Bread dough was prepared using the direct method. Bread loaves were cooled, and then their volume, texture, color, total phenolic content, and antioxidant activity were evaluated. In addition, a sensory evaluation of bread was performed. Incorporation of PL into wheat decreased the bread volume and increased the crumb moisture but had little influence on the crumb texture. The crumb of the enriched bread was darker and greener compared with the control sample. PL addition increased the redness of the crumb as well. The total color difference for the enriched bread ranged from 9.3 to 21.4. According to the sensory evaluation, the amount of wheat flour added to PL should not exceed 3%. Such a kind of bread showed about a twofold higher level of phenolic compounds and enhanced antioxidant activity compared with the control bread. This study showed that powdered PL can be a valuable nutritional supplement to wheat bread. Future research should focus on the possibilities of fortifying various types of food with this additive.
