Abstract

Dunaliella algae, which is rich in various kind of physiologically active ingredients, especially β-carotene, can be utilized in the form of dried powder. Dried powder of Dunaliella algae is granulated together with other materials to make a granulation and the granulation is encapsulated in a hard capsule. Dried powder of Dunaliella algae is also suspended in an emulsifier along with other materials to form a suspension and the suspension is encapsulated in a soft capsule.

Claims

1. A process for the production of foodstuffs containing Dunaliella algae encapsulated in a hard capsule comprising the following steps:

adding cyclodextrin to dried powder of Dunaliella algae in an amount so that the ratio of said cyclodextrin to said powder is from 15-50 parts by weight to 100 parts by weight;

stirring and blending said cyclodextrin and said powder in a mixer;

adding, to 100 parts by weight of the mixture of cyclodextrin and said powder, from 0.10 to 0.25 parts by weight of an antioxidant and selected from the group consisting of vitamin C and vitamin E, from 3.50 to 4.50 parts by weight of a lubricant selected from the group consisting of talc and esters of sucrose with a fatty acid; and

from 35.50 to 40.60 parts by weight of a binder selected from the group consisting of sugars;

blending said materials to make a mixture;

granulating said mixture in the form of granules; and

encapsulating said granules in a light-impermeable hard capsule.

3. The process according to claim 1 wherein the binder is reducing maltose.

2. A process for the production of a foodstuff containing Dunaliella algae in a soft capsule comprising the following steps:

blending from 1 to 10 parts by weight of a natural wax selected from the group consisting of lanolin and yellow beeswax, and from 1 to 10 parts by weight of an emulsifier selected from the group consisting of esters of glycerin with a fatty acid and monoglycerides, thereby obtaining an emulsion;

adding to said emulsion from 10 to 240 parts by weight of dried powder of said algae, from 10 to 260 parts by weight of vegetable oil, and from 1 to 10 parts by weight of an antioxidant selected from the group consisting of vitamin C and vitamin E;

stirring the mixture of said emulsion, said powder, said oil, and said antioxidant under vacuum to suspend the ingredients, thereby forming a suspension; and

encapsulating 300 parts by weight of said suspension in a light-impermeable soft capsule under a nitrogen atmosphere;

wherein, in each step, said natural wax, said emulsifier, said dried powder, said oil, and said antioxidant are in an amount that the total of the materials equals 300 parts by weight.
