Malto-Dextrin/10.3 Water/74.3 Emulsion can be spray dried at inlet temperatures of 350-400 F and outlet temperatures of 200-220 F. Guidelines: To avoid lumping and aid hydration, "Emulgum" should be added slowly into the vortex of the solution using high-speed agitation. When used for encapsulation and spray drying of oils. "Emulgum" should be totally dissolved first and not dry mixed with other carriers. "Emulgum" must be used in aqueous solution. Prepasting with the oil and then adding to aqueous phase prevents proper hydration. For proper solubilization "Emulgum" should be hydrate with a minimum of 20 times its weight of water. To insure optimum and rapid hydration of the "Emulgum"; the use of warm water is suggested (140 F) To insure proper dispersion for coating of the oil droplets and stabilization of the emulsion, homogenization with high pressure on a twostage homogenizer is suggested. Ultrasonic homogenizers may be
配制方法:
To form a stable emulsion, the oil droplets should be no larger than 1.2 \m in size.
