CLAIMS

1 . A product comprising an oil in water emulsion, said emulsion comprising:

i) an oil phase comprising an admixture of about 30-60% oil and 0.01 -15% wax by weight of the emulsion, and surfactant component, wherein the surfactant component is a combination of non-ionic and ionic surfactant in a ratio of at least about 10: 1 to 30: 1 ; and

ii) an aqueous phase comprising about 30-50% by weight of the emulsion.

2. The product of claim 1 , wherein the oil is selected from the group consisting of high oleic acid/ low polyunsaturated fatty acid containing oils, high-oleic sunflower, high-oleic & high-stearic sunflower oil, high-oleic soybean, high-oleic canola, high-oleic safflower oil, avocado oil and olive oil, and medium and short-chain saturated triglycerides oils such as caprylic-capric triglyceride oils, Neobee oil and coconut oil, soybean oil, canola oil, sunflower oil, safflower oil, corn oil, flaxseed oil, almond oil, peanut oil, pecan oil, cottonseed oil, algal oil, palm oil, palm stearin, palm olein, palm kernel oil, hydrogenated palm kernel oil, hydrogenated palm stearin, fully hydrogenated soybean, canola or cottonseed oils, high stearic sunflower oil, enzymatically and chemically inter-esterified oils, butteroil, cocoa butter and mixtures.

3. The product of claim 2, wherein the oil is selected from the group consisting of soybean, canola, sunflower, palm oil and palm olein.

4. The product of claim 1 , wherein the wax is selected from the group consisting of rice bran wax, carnauba wax, candelilla wax, sunflower wax, jojoba oil wax, corn oil wax, sugarcane wax, ouricury wax and retamo wax.

5. The product of claim 1 , wherein the wax is present in an amount of about 2-10% by weight.

6. The product of claim 1 , wherein the non-ionic surfactant is selected from the group consisting of monoglycerides, diglycerides, poly-glycerol esters, phospholipids, and mixtures thereof.

7. The product of claim 6, wherein the non-ionic surfactant is selected from the group consisting of glyceryl monobehenate (GMB), glyceryl monstearate (GMS), glyceryl monpalmitate (GMP), glycerlyl monomyristate, glyceryl monolaurate, glyceryl monocaprate, and mixtures thereof.

8. The product of claim 6, wherein the ionic surfactant is selected from the group consisting of cationic phospholipids, cationic non-fatty carboxylic acid esters, anionic lactylated fatty acid salts, anionic phospholipids, anionic non-fatty carboxylic esters, fatty acids and fatty acid metal salts.

9. The product of claim 8, wherein the ionic surfactant is selected from the group consisting of stearic acid, palmitic acid, sodium stearoyl lactylate (SSL), phosphatidic acid and and lyso-phosphatidic acid.

10. The product of claim 1, wherein the ratio of non-ionic to ionic surfactant is about 20: 1.

1 1. The product of claim 1, comprising one or more additives selected from the group consisting of sugars such as sucrose, maltose, glucose, fructose, dextrins, maltodextrins, cyclodextrins, corn syrup, high fructose corn syrup, amylose, amylopectin, modified starches, dextran, cellulose, methylcellulose, hydroxypropylcellulose, xanthan gum, agarose, guar gum, locust bean gum, polysaccharides, proteins, vitamins, minerals, salt, natural flavourings, artificial flavourings, colorants, anti-oxidants and preservatives.

12. The product of claim 1 , having a yield stress of at least about 700 Pa and an elastic modulus of at least about 1 x105 Pa.

13. The product of claim 1 , comprising in the oil phase about 45-60% oil by weight, 3-6% by weight non-ionic surfactant, 0.1 -0.4% by weight ionic surfactant and 0.5-7.5% by weight wax, and about 35-50% by weight water.

14. The product of claim 13, comprising in the oil phase about 45-55% oil by weight, 4-6% by weight non-ionic surfactant, 0.2-0.4% by weight ionic surfactant and 5-7.5% by weight wax, and about 35-40% by weight water.

15. A process for making a product as defined in claim 1 , comprising the steps of:

i) preparing an oil phase by admixing the oil, wax and surfactant component, and heating the oil phase to a temperature above the melting point of the non-ionic surfactant ;

ii) preparing a heated aqueous phase;

iii) combining the aqueous phase and the oil phase and mixing to form an emulsion; and

iv) cooling the emulsion to form a solid comprising surfactant-encapsulated oil layers in a continuous aqueous phase.

16. The process of claim 15, wherein the oil phase is heated to a temperature which is about 5-10ºC above the melting point of the non-ionic surfactant and below the temperature at which the non-ionic surfactant transitions from the lamellar to cubic phase in water.

17. The process of claim 15, wherein the aqueous phase is heated to the same temperature as the oil phase.

18. The process of clam 15, wherein the oil is a triacylglycerol oil.

19. The process of claim 15, wherein the non-ionic surfactant is selected from the group consisting of monoglycerides, diglycerides, poly-glycerol esters, phospholipids and mixtures thereof, and the ionic surfactant is selected from the group consisting of stearic acid, palmitic acid, sodium stearoyl lactylate (SSL), phosphatidic acid, lyso- phosphatidic acid and diacyl tartaric acid ester of monoglyceride.

20. The process of claim 15, wherein the wax is added in an amount of about 7- 10% by wt and is selected from the group consisting of rice bran wax, carnauba wax, candelilla wax, sunflower wax, jojoba oil wax, corn oil wax, sugarcane wax, ouricury wax and retamo wax.
