Research Producing the Instant Powder Product by Extracting Solution from VietnamMulberry Leaves (Morus albaL.)

The instant mulberry powder was produced by spray drying from condensed liquid extraction of mulberry leaves (supplemented with some additives). In this experiment, we have used the drying spray method (dryer spray MOBILE MINOR - Denmark) to produce instant powder from mulberry leaves grown in Viet Nam. Based on research and survey of technology parameters affect the drying and the rate of blending of additives suitable for the purpose of producing instant powders that DNJ content ≥ 1%, with taste, attractive colors, easy to use, we have identified technological processes producing instant powder of mulberry leaves with the specifications as follows: Using extraction solutions with total sub solid 200Bx the input temperature is 1300C, the input flow pump is 1500ml / h, the efficiency of product reached 60% (Wsp <5% ). To create tasting of product, condensed solution of dry mulberry leaves should be added a number of additives such as 0.6% sweet grass; 6% strawberry flavor.
