Abstract
Official abstract text for this publication.
Aqueous suspensions comprising: (a) at least one carotenoid, (b) at least one modified starch, and (c) sucrose; wherein the at least one carotenoid is present in the suspension in an amount of 1 to 25% by weight, based on the dry matter of the aqueous suspension; and wherein the at least one carotenoid and the sucrose are present in the suspension in a ratio by weight of 1:2 to 1:80; powders comprising: (a) at least one carotenoid, (b) at least one modified starch, and (c) sucrose; wherein the at least one carotenoid is present in the powder in an amount of 1 to 25% by weight, based on the weight of the powder; and wherein the at least one carotenoid and the sucrose are present in the powder in a ratio by weight of 1:2 to 1:80; and processes of producing such suspensions and powders along with uses thereof.
First claim
Opening claim text (preview).
We claim: 1. An aqueous suspension comprising: (a) at least one carotenoid selected from the group consisting of β-carotene, zeaxanthin, lutein, and mixtures thereof, (b) at least one modified starch comprising octenylsuccinate starch, and (c) sucrose; wherein the at least one carotenoid is present in the suspension in an amount of 8 to 13% by weight, based on the dry matter of the aqueous suspension; and wherein the at least one carotenoid and the sucrose are present in the suspension in a ratio by weight of 1:5 to 1:10. 2. The aqueous suspension according to claim 1 , wherein the at least one carotenoid comprises nanoparticles. 3. The aqueous suspension according to claim 1 , wherein the at least one carotenoid is β-carotene and the sucrose are present in a ratio by weight of 1:5 to 1:7.2. 4. The aqueous suspension according to claim 1 , wherein the at least one carotenoid is β-carotene.
