Frying processes utilizing cooking oil at elevated temperatures can cause various degradation effects in the oil including oxidation, hydrolysis and/or polymerization. In the absence of additives to protect the oil, the nutritional profile and cooking performance of degraded oil diminishes the quality of food cooked therein. The disclosed methods and compositions provide beneficial and cost effective improvements in the cooking performance of oil used at elevated temperatures, for example, in food frying equipment.

The invention claimed is: 1. A process for stabilizing hot cooking oil comprising periodically introducing into said hot cooking oil a composition comprising: (A) water; (B) at least one herb or herbal extract; and (C) at least one functional additive selected from the group consisting of food acid
The invention claimed is: 1. A process for stabilizing hot cooking oil comprising periodically introducing into said hot cooking oil a composition comprising: (A) water; (B) at least one herb or herbal extract; and (C) at least one functional additive selected from the group consisting of food acids, food acid derivatives including glycerol esters of said food acids, and mixtures thereof; and provided said composition does not include a particulate mineral carrier. 2. The process of claim 1 wherein said herb or herbal extract is selected from the group consisting of turmeric, rosemary, oregano, sage, garlic, ginger, peppermint, purslane, bilberry, milk thistle, grape seed, green tea, maritime pine and St. John's wort. 3. The process of claim 2 wherein said herb or herbal extract is selected from the group consisting of turmeric and rosemary. 4. The process of claim 1 wherein said food acid is selected from the group consisting of citric acid, tartaric acid, malic acid, lactic acid, acetic acid, fumaric acid, ascorbic acid, isoascorbic acid, succinic acid, adipic acid, hydrochloric acid, phosphoric acid, and ethylenediamine tetraacetic acid. 5. The process of claim 3 wherein said at least one food acid or food acid derivative is selected from the group consisting of citric acid, ascorbic acid, glycerol ester of citric acid and ascorbyl palmitate. 6. The process of claim 4 wherein said food acid is citric acid. 7. The process of claim 1 wherein said composition further comprises a water-soluble or water dispersible emulsifier. 8. The process of claim 1 wherein said at least one functional additive is a dual functional additive that exhibits antioxidant and emulsifier characteristics. 9. The process of claim 8 wherein said at least one dual functional additive is selected from the group consisting of ascorbyl palmitate; citric acid and fatty acid esters of glycerol; sodium, potassium and calcium lactates; sodium and potassium tartrates; sodium, calcium and potassium citrates; sodium, potassium, calcium, ammonium and magnesium phosphates; and lecithin. 10. The process of claim 1 wherein the temperature of said hot oil is about 225° F. to about 400° F. 11. The process of claim 1 wherein in the introduction of said composition is at a controlled rate such that the aqueous component is not explosively transformed into steam. 12. The process of claim 11 wherein said composition is introduced in a form selected from the group consisting of a fine stream, a mist, a fog, small diameter liquid droplets, an aerated stream and aerated small diameter droplets. 13. The process of claim 12 wherein aeration is accomplished by incorporation of air or an inert gas. 14. The process of claim 12 wherein said composition is introduced, relative to the top surface of said hot oil, from at least one of the following: above; below; and above and below. 15. The process of claim 14 wherein said composition is introduced from below said top surface of said hot oil through at least one injection orifice. 16. The process of claim 14 wherein said composition is introduced from above the top surface of said hot oil through at least one orifice in communication with a reservoir comprising said composition. 17. The process according to claim 16 wherein said reservoir comprises a hand held container capable of delivering a liquid stream or spray. 18. The process of claim 17 wherein said hand held container comprises a squeeze bottle including an orifice for producing a liquid stream or spray. 19. The process of claim 16 wherein said hand held container comprises a pump or trigger mechanism in combination with a fine orifice or spray nozzle. 20. The process of claim 1 wherein said periodic introduction is correlated with at least one oil quality test. 21. The process of claim 20 wherein said test is selected from the group consisting of polymerized triglycerides content, polar compounds content, free fatty acid level, peroxide level, taste, odor and color. 22. The process of claim 20 wherein said composition is introduced using an automated system. 23. The process of claim 1 wherein said composition is introduced at a rate or in an amount, or both, corresponding to the rate or extent of degradation of said oil. 24. The process of claim 1 wherein said water has a reduced concentration of minerals therein. 25. The process of claim 1 wherein said emulsifier is nonionic. 26. The process of claim 1 wherein said composition comprises up to about 5 wt. % emulsifier. 27. The process of claim 1 wherein said composition comprises about 0.0001 wt. % to about 5 wt. % emulsifier.
