Spray Drying Parameters Affecting to Dried Powder from Palmyra Palm (Borassus flabellifer) Juice

The optimal parameter was selected by comparing different values of the spray-dried powder such as moisture content (%), water activity (aw), total phenolic (mg GAE/g), ascorbic acid (mg/100g), carotenoid (mg/ 100g), bulk density (g/ml), yield (%), solubility (%), hygroscopicity (%), total plate cou...

Description
Summary:The optimal parameter was selected by comparing different values of the spray-dried powder such as moisture content (%), water activity (aw), total phenolic (mg GAE/g), ascorbic acid (mg/100g), carotenoid (mg/ 100g), bulk density (g/ml), yield (%), solubility (%), hygroscopicity (%), total plate count (cfu/g), sensory score. 2.2.2 Effect of speed flow rate to moisture content, water activity, total phenolic, ascorbic acid, carotenoid, bulk density, yield, solubility, hygroscopicity, total plate count, sensory score in spray-dried powder Different speed flow rate (4, 8, 12, 16 ml/ min) was examined. The optimal parameter was selected by comparing different values of the spray-dried powder such as moisture content (%), water activity (aw), total phenolic (mg GAE/g), ascorbic acid (mg/100g), carotenoid (mg/ 100g), bulk density (g/ml), yield (%), solubility (%), hygroscopicity (%), total plate count (cfu/g), sensory score. 2.3 Physico-chemical, microbial and sensory evaluation Moisture content (%) was determined by comparing the weights of the sample with the electronic balance. Result & Discussion 3.1 Effect of inlet/ outlet spray drying temperature to moisture content, water activity, total phenolic, ascorbic acid, carotenoid, bulk density, yield, solubility, hygroscopicity, total plate count, sensory score in spray-dried powder Processing factors affecting particle size, loose density and nutrient contents of the spray-dried powder include inlet and outlet drying temperature (Phisut, N., 2012). According to Walton (2000), increasing air-drying temperature or decreasing feed flow rate generally resulted in a decrease in bulk density and there was a greater tendency for particles to be hollow.
