Preparation, characterization and sensory analysis of whole bread enriched with papaya byproducts flour

Abstract Due to the industrial processing of papaya, a great amount of byproducts from this fruit is generated. The peel and seeds are amongst these byproducts and have great nutritional value, since they present considerable amounts of fibre, lipids, proteins and antioxidants. The objective of this study was to develop whole wheat bread loaves with the addition of a mixed flour made from the peel and seeds of papayas of the Hawaiian cultivar. In the whole-grain breadmaking process, the mixed flour (peel and seeds) was added in different concentrations (0%, 3%, 6% and 9%), in the proportion of 70% of papaya peel flour to 30% of papaya seed flour. The addition of the mixed flour resulted in products with high fibre (7.96 g 100 g-1) and protein (12.71 g 100 g-1) contents and low lipid contents (0.55 g 100 g-1). The results of the sensory analysis showed that the bread made with the addition of 3% of the mixed flour resulted in good acceptance when compared to the control. Thus the addition of papaya byproducts flour in the manufacture of bread is a good alternative for the diet of the population, since it is nutritionally rich in fibre and protein.
