Determination of biochemical properties of foam-mat dried mango powder

P>Investigations were carried out to see the impact of drying air temperature (65, 75 and 85 degrees C) and milk as foaming agent in different concentration levels (0%, 10%, 15%, 20% and 25%) on the chemical properties of foam-mat dried mango juice powder. Chemical properties such as total sugars, ascorbic acid, total carotenes, minerals, total acid, pH, total soluble solids (TSS) and microbial load (fungal and bacterial) of foam-mat dried mango powder were determined. Data were analysed as per two-way anova, Duncan's multiple range test and l.s.d. of AgRes Software statistical package. Almost all chemical properties show decreasing trend with increase in drying air temperature. Microbial load was not detected in foam-mat dried mango powder. It was found that addition of 10% milk as foaming agent and drying at 65 degrees C temperature gave better results.
