Abstract
The current study was conducted to investigate the hypocholesterolemic effect of dietary orange albedo powder (OrAP), potato peel powder (PoPP) and carrot pomace powder (CaPP), as a source of natural fibers on hypercholesterolemia and various oxidative stress-associated with biochemical parameters in hypercholesterolemic rats. Furthermore production of a bread having higher natural fiber contents, formed from these by-products.
The chemical composition of the plant samples showed that the PoPP has a high value of crude fiber (19.55g/100g dry weight basis), compared with carrot pomace (11.80) and orange albedo (9.92). The diet was supplemented with 10% and 20% of each (OrAP), (PoPP) and (CaPP) and their mixture. The obtained results revealed that the hypercholesterolemic rats which fed on the diet supplemented with 20% PoPP and 20% mixture showed the highest significant improve in lipid profile, liver function, kidney function, blood picture and plasma glucose compared to positive and negative control. Also the rats fed on 20%CaPP showed the highest significant decrease in body weight gain compared to positive control. In addition, the sensory evaluation of the bread which formed from these by-products showed that the bread contained 10% OrAP had non significant changes in taste and crumb color compared with control. On the other hand, the bread that contained 20% PoPP showed the lowest values in taste, aroma, mouth feel and crumb texture among all samples.
