Kajian Pengeringan Manisan Mangga (Mangifera Indica L.) Menggunakan Hot Air Rotary Oven

Abstract

Processing of mango become dry candied is one of a method to improve the added value and to extend the shelf life of the product. The objectives of this study was to investigate the effect of adding sugar concentration and drying temperature to the drying rate and quality of mango candied. The treatments of sugar concentration of 40 o and 60 oBrix and temperature of 40 oC, 45 oC, and 50 oC were applied to this research. Air velocity of hot air rotary oven that used in this experiments was 2 m/sec. The result showed that sugar concentration and drying temperature affected the drying rate. The lower sugar concentration and higher drying temperature was accelerate the drying rate. Drying temperature affected colour and hardness of mango candied. Mango candied that was processed using hot air rotary oven with 40 oBrix of sugar concentration and 40 oC of drying temperature resulting the best quality of mango candied based on parameter quality of hardness, colour, and organoleptic test.
