Stabilisation of natural dyes by an acerola powder
The invention concerns a powder consisting of 0.5 to 8% by weight of water and a dry material consisting of 88 to 95% by weight of an acerola fruit dry extract and 5 to 12% by weight of magnesium, calcium, zinc, sodium or potassium hydroxide or carbonate, the method of preparing same and the applications thereof for stabilizing a natural dye.
1. A food additive or ingredient, comprising:
a natural dye comprising one or more natural pigments; and
a powder component consisting of:
0.5% to 8% by weight of water, relative to the total weight of the powder component; and
a dry material consisting of:
88% to 95% by weight of an acerola fruit dry extract, relative to the total weight of the dry material; and
5% to 12% by weight of a hydroxide or carbonate of magnesium, calcium, zinc, sodium or potassium, relative to the total weight of the dry material,
wherein the acerola fruit dry extract provides the powder component with a natural vitamin C content of 30% to 40% by weight, relative to the total weight of the powder component.
2. The food additive or ingredient according to claim 1 , wherein the natural dye comprises a red beet juice concentrate or a red beet powder.
3. A food or food composition comprising the food additive or ingredient according to claim 1 combined with a food component.
4. The food additive or ingredient according to claim 1 , wherein the one or more natural pigments include betanin.
5. The food additive or ingredient according to claim 1 , wherein the powder component contains a natural vitamin C content of 34%±3% by weight, relative to the total weight of the powder component.
6. The food additive or ingredient according to claim 1 , wherein the powder component has a pH varying from 4 to 8.
7. The food additive or ingredient according to claim 1 , wherein the powder component consists of 0.5% to 5% by weight of water, relative to the total weight of the powder component.
8. A method of producing a food additive or ingredient, the method comprising combining a powder component with a natural dye, the powder component consisting of:
0.5% to 8% by weight of water, relative to the total weight of the powder component, and
a dry material consisting of:
88% to 95% by weight of an acerola fruit dry extract, relative to the total weight of the dry material; and
5% to 12% by weight of a hydroxide or carbonate of magnesium, calcium, zinc, sodium or potassium, relative to the total weight of the dry material,
wherein the acerola fruit dry extract provides the powder component with a natural vitamin C content of 30% to 40% by weight, relative to the total weight of the powder component,
the natural dye comprising one or more natural pigments, the powder component stabilizing the natural dye.
9. The method according to claim 8 , wherein the one or more natural pigments include betanin.
