Embodiment 1
[0028] Example 1. For a small test, 40g neotame was dissolved in 80g ethanol solution containing 10% Tween 80. In addition, 950 g of maltodextrin and 1000 g of water were mixed and vigorously stirred to form a slurry. The slurry was heated to about 70° C., kept for 2 minutes, and then cooled to 26° C. Add the neotame solution into the cooled maltodextrin slurry, mix for about 5 minutes, and then use a centrifugal spray dryer (inlet air temperature 180°C, outlet air temperature 70°C, sprayer speed 5000rpm) to spray dry. The final product has a moisture content of about 4.1%, contains about 4.0% neotame (standard deviation about 0.25%) as determined by HPLC, and has a particle size of about 25 to about 150 microns.
Embodiment 2
[0029] Example 2. In the pilot test, 4kg of neotame was added to 8kg of ethanol solution containing 10% Tween 80, and stirred until completely dissolved. In addition, 95kg of maltodextrin and 100kg of water were mixed and vigorously stirred to form a slurry. The slurry was heated to about 70°C, kept for 2 minutes, and then cooled to 26°C. Add the neotame solution into the cooled maltodextrin slurry, mix for about 10 minutes, and then use a centrifugal spray dryer (inlet air temperature 180°C, outlet air temperature 70°C, sprayer speed 5000rpm) to spray dry. The final product has a moisture content of about 4.3%, contains about 4.0% neotame (standard deviation about 0.25%) as determined by HPLC, and has a particle size of about 25 to about 150 microns.
Embodiment 3
[0030] Example 3. For a big test, add 40kg neotame to 80kg ethanol solution containing 10% Tween 80, heat (below 50°C) and stir until completely dissolved. In addition, 950kg of maltodextrin and 1000kg of water were mixed and vigorously stirred to form a slurry. The slurry was heated to about 70°C, kept for 2 minutes, and then cooled to 26°C. Add the neotame solution into the cooled maltodextrin slurry, mix for about 5 minutes, and then use a centrifugal spray dryer (inlet air temperature 180°C, outlet air temperature 70°C, sprayer speed 6000rpm) to spray dry. The final product has a moisture content of about 4.7%, contains about 4.0% neotame (standard deviation about 0.25%) as determined by HPLC, and has a particle size of about 25 to about 150 microns.
