Problems solved by technology

These documents have announced the method that can prepare the carotenoid substance particle of nano-scale particle size, but its finished product aqueous solution is often in the form of emulsion, and it is also inconvenient to store and transport
[0005] The publication number applied by BASF company is CN1348483A "The stable water dispersion of lutein and the stable water dispersible dry powder and its preparation and application", the formed dry powder can be dispersed in water to form a transparent powder with an average particle diameter of 129nm. Dispersion, but the preparation process requires a higher temperature (> 170 ° C), because the solvent used is isopropanol and other systems, so it needs to use high-pressure resistant equipment, the production is difficult and the process is more complicated
Publication No. CN101143132 provides "a kind of preparation method of water-soluble nanoparticles with high β-carotene content", which adopts vegetable oil solution, n-hexane or cyclohexane solution and emulsifier through high-pressure homogenization, and further Freeze-drying with volatile solvents can obtain β-carotene water-soluble nanoparticles freeze-dried powder, and the preparation method and process are still relatively complicated and unsatisfactory

Embodiment 1

[0018] Dissolve 10 grams of lutein in 1200ml of isopropanol at 65°C to make an organic solution phase; mix 0.5 grams of xanthan gum, 20 grams of Tween 80, 23 grams of gum arabic, 12 grams of β-cyclodextrin, and 0.1 grams of Sodium CMC is dissolved in 1000ml 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 is evaporated under reduced pressure, 25 grams of water-soluble starch, 5 grams of sucrose, and 5 grams of sodium caseinate are added, stirred evenly, and spray-dried to obtain the corresponding water-soluble lutein powder product. Dissolve the powder product in cold water to make a transparent yellow solution of 0.1% aqueous solution, with an average particle size of 162nm. After being centrifuged at 2000 rpm for 20 minutes, no sediment or suspended matter appears; it is still very uniform wit...

Embodiment 2

[0020] After dissolving 10 grams of lycopene in 600ml of acetone at 50°C, add it to a 1000ml aqueous phase solution containing 15 grams of Tween, 30 grams of gum arabic, 5 grams of peach gum, and 5 grams of PVP. 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 plain bud dextrin to the remaining liquid after evaporating the organic solvent, stir evenly, and spray dry to obtain a dark red powder product. Dissolve the product powder in water to prepare a 0.1% red transparent solution with an average particle size of 95nm. After centrifugation at 3000 rpm for 10 minutes, no sediment and suspended solids were produced, 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, and add this solution to 1000 ml of aqueous phase solution containing 10 grams of sucrose ester, 10 grams of S-40, 15 grams of gum arabic and 10 grams of β-cyclodextrin, Stir at a high speed of 8000-10000 rpm for 2 hours and mix thoroughly. Add 40 grams of oxidized starch, 100 ml of 1% xanthan gum aqueous solution and 10 grams of pullulan to the residue after evaporating the acetone solvent, stir evenly, and spray dry to obtain a red powder product. The powder product is dissolved in water to form a red transparent solution, and the measured average particle size is 131nm. The solution remains unchanged after being centrifuged at 3000 rpm for 10 minutes; it remains unchanged for 90 days at room temperature.

Abstract

The invention relates to a preparation method for stable water soluble carotenoid dry powder, the organic solvent of acetone or isopropanol dissolved with carotenoid component is added into an aqueous phase solvent containing a surfactant and adjuvant-stabilization component to be sufficiently mixed under sufficient stirring, then the organic solvent in the mixed solvent is removed and an auxiliary forming accessory which is one to twelve times of the carotenoid component by mass is added to be evenly stirred and treated with sponging frying to obtain the powder product. The preparation method is simple and easy, complex operation such as high pressure homogenization is not needed, and the procedures are less, therefore, the method is applicable to various carotenoid components containing Beta-carotene, astaxanthin, lutein, corn pigment and lycopene, etc. The method has the advantages that the performance of the products is good, the grain diameter of the powder product can be in the range of 90 to 170 nm, and the product can be evenly dispersed in water and form a stable and transparent carotenoid water dispersoid solvent.

Description

technical field [0001] The invention relates to a preparation method of highly stable nanometerized water-soluble carotenoid dry powder. Background technique [0002] Carotenoids are extremely difficult to dissolve in water, thus greatly limiting their application in beverages, oral liquids, medicinal or feed, liquid preparations and other liquid products. [0003] For this reason, the current common method is to increase its water solubility by means of emulsification or microencapsulation. For example, the Chinese patent document with the publication number CN1757315A discloses a "water-soluble lutein", the Chinese patent document with the publication number CN101032683A discloses a "lutein microcapsule and its preparation method", and CN101015342 discloses a "tomato red The preparation method of plain microcapsules", CN1081333 discloses a kind of "natural beta-carotene aqueous solution and preparation thereof", and CN1623983 discloses a kind of " method and method for pr...
