Convective Air Drying of Papaya Pre-Treated with Phyllanthus Niruri Solutions

摘要：

The objectives of this study are to investigate the effects of pre-treatment on drying kinetics and total polyphenol content (TPC) of papaya.Papayas were pre-treatment with two different types of osmotic solution; sugar solution with presence of phyllanthus niruri powders and sugar solution without phyllanthus niruri powders.It was found that drying rate of papayas pretreated by phyllanthus niruri solutions were higher than samples without pretreated by phyllanthus niruri solutions.Effective diffusivities obtained were ranged from 2.085 × 10-11 to 1.227 × 10-9 m2/s, which were determined using the Fick’s second law.Further to this, it was found that the TPC of the dehydrated papaya with and without pretreated in phyllanthus niruri solution were ranged from 37.9 ± 0.19 to 62.0 ± 0.09 mg GAE/ 100g and 34.2 ± 0.37 to 55.8 ± 0.06 mg GAE/ 100g, respectively.
