Evaluation of Pomegranate Peel Fortified Pan Bread on Body Weight Loss

Abstract

Pomegranate (Punica granatum L.) peel is a nutritive, antioxidant rich by-product, easily available after production of pomegranate juice and ready to eat arils. The aim of present study was to utilize of pomegranate peel powder (PPP) as a good source of fiber ingredient and antioxidant bioactive compounds to produce value add bakery product based on pomegranate peel powder 2.5%, 5%, and 7.5% and investigation of weight loss activity in rats fed on high fat diet (HFD). Chemical composition, total phenols, total flavonoids and anti-oxidative activity (DPPH) of PPP and pan breads were determined. Texture profile analysis (TPA), sensory evaluation and physical properties of pan breads were investigated. Pan bread fortified with 2.5% and 5% PPP had higher score in overall acceptability and physical properties when compared to control pan bread and other various concentration (7.5%) of PPP. Thirty-six female albino adult rats with an average weight (180 ±5 g) were divided into six groups 6 rats for each. The first group (G1) fed on basal diet as a (negative control group). The other rats (30 rat) were divided as follow : (G2) fed on HFD as a positive control (PC), (G3) fed on HFD with PPP free pan bread , (G4) received HFD with 2.5% PPP fortified pan bread, (G5) received HFD with 5% PPP fortified pan bread and (G6) fed on HFD with 7.5% PPP fortified pan bread. Food intake, food efficiency, body weight, gain %, epididymal adipose tissue (g) and organs weight were recorded. Serum lipid profile and liver enzymes were analyzed. Our results showed that pomegranate peel powder 7.5% followed by 5% fortified breads reduced body weight by (47.61±1.27% and 40.65±1.11%) respectively, compared with PC group. Total lipid, triglycerides total cholesterol, LDL-C, VLDL-C and liver functions were decreased by increasing of PPP level in pan bread while HDL-C was increased .In conclusion, our results concluded that pomegranate peel powder fortified breads with high fiber and anti-oxidative activities is recommended to gain nutritional and healthy benefits to weight loss activity and the risk of obesity.

Pomegranate (Punica granatum L.) peel hydro alcoholic extract ameliorates cardiovascular risk factors in obese women with dyslipidemia: A double blind, randomized, placebo controlled pilot study

“…Some studies indicated pomegranate peel extract induces weight loss in mice, due to its effect on reducing serum TG and plasma glucose concentration [40,41]. By considering significant reduction in serum TG and TC levels in pomegranate peel extract group in our study, it was possible that, longer duration of intervention results in significant changes of body weight.…”
