Physiological Effects of Agroindustrial Co-Products: Cactus (Opuntia ficus) Pear Peel Flour and Stripe Apple (Malus domestica) Marc Flour on Wistar Rats (Rattus norvegicus)
Abstract
Agro-industrial co-products as fruit peel can be used as alternative and cheap fiber and prebiotics resources. The objective of this work was to evaluate rats’ in vivo physiological effect the in vivo effect of apple marc and cactus pear peel during 90 days. Inulin (as control) containing diet resulted in higher average body weight, but apple marc diet showed the same body weight gain. Diets reduced glucose and triglycerides in serum. Lactic acid bacteria and Bifidobacteria count were higher in cactus peel flour diet, although apple marc diet resulted in better fatty acids production. Due to higher insoluble fiber, apple marc flour and cactus pear peel flour resulted in higher non-digestible carbohydrates. Apple marc flour showed similar physiological effects as compared to inulin and can be employed as a good prebiotic source.
