Papaya by-products for providing stability and antioxidant activity to oil in water emulsions.

ABSTRACT: The consumption of food with health benefits is growing today worldwide. This study was designed in order to incorporate papaya dietary fibre concentrates (DFCs) from peel and pulp dehydrated with the use of microwave (MW), or convection with hot air (CV) in oil-in- water emulsions. Results of studies indicated that Pulp DFC produced more stability to creaming (18 weeks) than Peel DFC (6 weeks). It was found that peel DFCs exerted up to 30% reduction in lipid peroxidation in comparison to the reference system during storage. Rheological analysis showed a similar behaviour when emulsions were mixed with pulp DFCs either dehydrated by MW or CV, while the dressing with peel DFCs had a much lower consistency than the former. The analysis of the emulsions micro-structure showed a polydisperse s
