Ketogenic nutritional composition and preparation method thereof
The present disclosure relates to nutritional composition in powder form capable of being used as an adjunct to a ketogenic diet program. The disclosed ketogenic nutritional composition can produce elevated and sustained levels of ketone bodies in blood and can synergistically induce nutritional ketosis in a subject. The ketogenic nutritional composition disclosed herein can exhibit improved physical stability, solubility, homogeneity and aqueous dispersibility as compared to existing ketogenic diet supplements, and is substantially free of carbohydrates. Further the disclosed ketogenic nutritional composition can contribute to reduction in body fat mass in individuals who are trying to lose weight, and can provide long-lasting energy and improved athletic performance to individuals during strenuous exercise. In an aspect, the present disclosure provides a ketogenic nutritional composition in powder form for promoting nutritional ketosis in a subject in need thereof, wherein the composition can include a fat, protein, vitamin, and phospholipids.
1. A ketogenic composition, having zero carbohydrates, for promoting nutritional ketosis in a subject in need thereof, the composition comprising:
fat selected from the group consisting of coconut oil, fractionated coconut oil, medium chain triglyceride (MCT) oil and mixtures thereof present in a concentration of 80% by weight;
protein being a natural protein selected from casein, whey protein, egg protein, soy protein and a mixture of milk proteins in the range of 15-18% by weight;
vitamin being vitamin E in the range of 0.1-0.5% by weight; and
a natural phospholipid in the range of 0.5-2% by weight,
wherein the ketogenic composition is in powder form.
2. The ketogenic composition as claimed in claim 1 , wherein the fat comprises coconut oil.
3. The ketogenic composition as claimed in claim 1 , wherein the casein comprises sodium caseinate.
4. The ketogenic composition as claimed in claim 1 , wherein the vitamin E comprises α-tocopherol.
5. The ketogenic composition as claimed in claim 1 , wherein the natural phospholipids comprise soy phospholipids, and wherein the soy phospholipids comprise at least 50% phosphatidylcholine.
6. A method of promoting ketosis in a subject, comprises administering an effective amount of the composition of claim 1 to the subject in need thereof.
7. A method for producing a ketogenic powder composition, as claimed in claim 1 , comprising:
mixing a fat and a protein to form a first mixture;
mixing a vitamin and a phospholipid in an organic solvent to form a second mixture;
providing a spray drying apparatus comprising a three-fluid spray nozzle;
supplying the first mixture to the three-fluid spray nozzle through a first inlet;
supplying the second mixture to the three-fluid spray nozzle through a second inlet;
supplying an atomization gas to the three-fluid spray nozzle thorough a third inlet; and
spraying the first mixture and the second mixture through the three-fluid spray nozzle using an atomization gas to produce the ketogenic powder composition.
8. The method as claimed in claim 7 , wherein the organic solvent comprises ethanol.
9. The method as claimed in claim 7 , wherein the atomization gas comprises nitrogen gas.
10. The method as claimed in claim 7 , wherein the protein comprises sodium caseinate.
11. The method as claimed in claim 7 , wherein the vitamin E comprises α-tocopherol.
12. The method as claimed in claim 7 , wherein the natural phospholipid comprises a soy phospholipid.
13. The method as claimed in claim 12 , wherein the soy phospholipid comprises at least 50% phosphatidylcholine.
