Diet product comprising alginate
The present invention relates to a diet product comprising an alginate in an aqueous dissolved or swelled form at a pH value causing the alginate not to gel.
1. A beverage or drink product comprising an alginate in an aqueous dissolved or swelled form, wherein the pH of the beverage or drink product is pH 5 or more so as to not cause the alginate to gel, wherein the alginate is present at a concentration of 0.2 to 20 g per kg of the beverage or drink product, and wherein the viscosity of the alginate increases to 20 times or more when the pH is decreased from pH 7 to pH 2.
2. The beverage or drink product according to claim 1 , wherein the molecular weight of the alginate is 150,000 or below.
3. The beverage or drink product according to claim 1 , wherein the alginate has a viscosity in a 4% aqueous solution not exceeding 800 cP, measured at 20° C. on a Brookfield RV viscometer, spindle N o 2, 20 rpm.
4. The beverage or drink product according to claim 1 , wherein the alginate has a viscosity in a 4% aqueous solution between 100 and 800 cP, measured at 20° C. on a Brookfield RV viscometer, spindle N o 2, 20 rpm.
5. The beverage or drink product according to claim 4 , wherein the alginate has a viscosity in a 4% aqueous solution between 200 and 600 cP, measured at 20° C. on a Brookfield RV viscometer, spindle N o 2, 20 rpm.
6. The beverage or drink product according to claim 1 , further comprising an insoluble calcium salt, wherein the amount of insoluble calcium salt in the beverage or drink product provides less than 200 ppm calcium ions when the pH is changed to pH 2.
7. The beverage or drink product according to claim 6 , wherein the amount of insoluble calcium salt in the beverage or drink product provides less than 50 ppm dissolved calcium ions when the pH is changed to pH 2.
8. The beverage or drink product of claim 1 , wherein the alginate is present at a concentration of 1.5 to 10 g per kg of the beverage or drink product.
9. The beverage or drink product according to claim 1 , wherein the viscosity of the beverage or drink product increases 50 times or more when the pH is decreased from pH 7 to pH 2.
10. The beverage or drink product according to claim 1 , wherein the viscosity of the beverage or drink product increases 100 times or more when the pH is decreased from pH 7 to pH 2.
11. The beverage or drink product according to claim 1 , further comprising an insoluble calcium salt, wherein the amount of insoluble calcium salt is present in an amount of less than 1% weight based on the weight of the alginate.
12. The beverage or drink product according to claim 1 , wherein the beverage or drink product further contains a mono- or disaccharide in a concentration of 0.1 to 60 g per kg, preferably 10 to 40 g per kg.
13. The beverage or drink product according to claim 12 , wherein the mono- or disaccharide is selected from the group consisting of saccharose, glucose, invert sugar or mixtures thereof.
14. The beverage or drink product according to claim 1 , which is a beverage.
15. The beverage or drink product according to claim 1 , which is a soft drink.
16. The beverage or drink product according to claim 1 , wherein the alginate is sodium alginate.
17. The beverage or drink product according to claim 1 , wherein it is present in a concentrated state.
18. A method for regulating consumption of foods in a subject in need thereof comprising the step of the subject consuming an effective amount of the beverage or drink product according to claim 1 at least 10 minutes prior to a main meal.
19. A method for regulating consumption of the diet product in a subject in need thereof comprising the step of the subject consuming the beverage or drink product according to claim 1 in such amounts that the faeces has density of 1 g/cm 3 or below.
20. The method according to claim 19 , wherein the faeces has a density of 0.9 g/cm 3 or below.
21. A method for regulating the blood sugar in a subject in need thereof comprising administering to the subject a pharmaceutically effective amount of the beverage or drink product according to claim 1 .
22. A method for lowering the level of cholesterol in a subject in need thereof, comprising administered to the subject a pharmaceutically effective amount of the beverage or drink product according to claim 1 .
