Embodiment 1
[0018] Dissolve 10 g of lutein in 1200 ml of isopropanol at 65°C to prepare an organic solution phase; mix 0.5 g of xanthan gum, 20 g of Tween 80, 23 g of gum arabic, 12 g of β cyclodextrin, 0.1 g CMC sodium is dissolved in 1000 ml of water to make an aqueous phase, and the organic phase solution is added to the aqueous phase under high-speed stirring at 3000-5000 rpm, and the stirring is continued for 2 hours to fully disperse and mix. After the organic solvent was evaporated under reduced pressure, 25 g of water-soluble starch, 5 g of sucrose, and 5 g of sodium caseinate were added, stirred uniformly, and spray-dried to obtain the corresponding water-soluble lutein powder product. Dissolve the powder product in cold water to form a transparent yellow solution of 0.1% aqueous solution, with an average particle size of 162nm. After a 20-minute centrifugation test at 2000 rpm, no precipitation or suspended matter appeared; it was still uniform and no precipitation after being place...
Embodiment 2
[0020] After dissolving 10 grams of lycopene in 600ml acetone at 50℃, add it to 1000ml aqueous solution containing 15 grams of Tween, 30 grams of gum arabic, 5 grams of peach gum, and 5 grams of PVP at 11000 revolutions per minute. Stir at high speed for 2 hours to fully disperse and mix. Add 3 grams of β-cyclodextrin, 10 grams of sucrose and 30 grams of prime dextrin to the remaining liquid after steaming the organic solvent, stir evenly, and spray-dry to obtain a deep red powder product. The product powder is dissolved in water to prepare a 0.1% red transparent solution with an average particle size of 95nm. After a 10 minute centrifugation test at 3000 rpm, there was no precipitation and suspended matter, and there was no change after 60 days at room temperature.
Embodiment 3
[0022] Dissolve 10 grams of astaxanthin in 1000 ml of acetone at 50°C. Add this solution to 1000 ml of aqueous solution containing 10 grams of sucrose esters, 10 grams of S-40, 15 grams of gum arabic and 10 grams of β-cyclodextrin. Stir at high speed at 8000-10000 rpm for 2 hours and mix well. Add 40 grams of oxidized starch, 100 ml of 1% xanthan gum aqueous solution and 10 grams of pullulan to the residue after steaming the acetone solvent, stir evenly, and spray-dry to obtain a red powder product. The powder product was dissolved in water to form a red transparent solution, and the average particle size was determined to be 131 nm. The solution was centrifuged at 3000 rpm for 10 minutes without change; it remained unchanged at room temperature for 90 days.
