| 3 | Phospholipid-based removal of sterols from fats and oils | US791915 | 1997-01-31 | US5880300A | 1999-03-09 | Dharma R. Kodali |
| Disclosed is a method for reducing the sterol, for example cholesterol, content of sterol-containing substances such as fats and oils. The method provides an efficient and cost effective process based on the affinity of cholesterol and other sterols for phospholipid bilayers. Phospholipid aggregates are contacted with, for example, a sterol-containing fat or oil in an aqueous environment and then mixed. Following adequate mixing, the sterol-reduced fat or oil is separated from the aqueous separation mixture. Alternatively, the correspondingly sterol-enriched phospholipid also may be isolated from the aqueous separation mixture. | ||||||

| The invention relates to a process for the selective alcoholysis of a free sterol, by contacting said free sterol with a fat-based product, optionally with the addition of carboxylic fatty acid(s) and/or ester derivative(s) thereof that are not derived from said fat-based product, in the presence of an immobilized lipase complex which may optionally be surfactant-coated, which complex possesses a high level of sterol-specific alcoholytic and/or esterfication activity and minimal acidolytic and transesterification activities. The fat-based product is a nutritional product or food, particularly butterfat, or a cosmetic or cosmetic or cosmetic-related product. The process may be used for preparing substantially cholesterol-free fat-based products, particularly products containing butterfat, by selectively esterfying any free cholesterol contained therein by the immobilized, preferably surfactant coated lipase. The invention also relates to a process for the in situ enrichment of a fat-based product with esterified phytosterol ester(s). In this process, the esterification of the phytosterol is simultaneously accompanied by esterification of any free cholesterol present in said fat-based product. | ||||||
