Description

Process for producing oil composition {A METHOD TO PRODUCE AN OIL COMPOSITION}

The present invention relates to a method of preparing an oil composition.

Phytonutrients are chemicals in plants that, in addition to vitamins and minerals, provide additional useful ingredients for the body. There are several types of phytonutrients, including major substances such as carotenoids and tocotrienols. Phytonutrients play a major role in disease prevention by acting as antioxidants, immunomodulators and anti-inflammatory agents, anti-aging and cancer-treating agents.

Natural phytonutrients are ingredients such as tocopherol, palm tocotrienol, pro-vitamin A (carotene), sterols, squalene and the like. Recently, due to the increasing interest in the health of consumers, the demand for premium oil products is increasing. In the past, several conventional methods have been used to prepare phytonutrient rich oil compositions with good low temperature stability and have been used in temperate regions such as the United States, Europe, Japan and Korea.

Thus, there is still a need for oil compositions rich in natural phytonutrients prepared from blends of highly unsaturated vegetable oils and palm oils with good low temperature stability and methods for their preparation.

However, embodiments of the present invention are merely examples of the present invention and may be implemented in various forms. Therefore, the drawings disclosed herein are not to be construed as limitations of the invention, but merely serve as a basis for describing the invention to those skilled in the art.

The present invention provides a method for preparing an oil composition which is rich in natural phytonutrients and comprises fatty acids, in particular for use in food preparation such as cooking, frying, salad dressing, and the like.

First, the feed oil is purified (see FIG. 1). By feed oil is meant palm oil and other unsaturated oils. Next, palm oil comprising carotene and other phytonutrients is blended with other unsaturated oils, such as soybean oil and canola oil, in a blend ratio of 9: 1 to 1: 2, preferably 6 Blend at a ratio of 4: 4. The blend oil is then heated at a temperature in the range of 40 ° C. to 50 ° C. to destroy all crystals before crystallization takes place.

The blend oil is subjected to a fractionation process to produce a liquid fraction with highly unsaturated fatty acid contents, which results in good low temperature stability (below 6 ° C). Unsaturated fatty acids derived from such unsaturated oils can enhance unsaturated fatty acids, thus maintaining a liquid state during the fractionation process. With this, the output of the process can also be increased due to the increase in the liquid oil produced. The blend ratio of the oil should be compatible with the melting point and crystallization behavior of the mixture.

The cooling process is then started in a crystallizer with a stirrer. The stirrer should be able to continuously stir at a constant rate following the process for coagulation of the crystals formed. A constant stirrer speed is necessary to control the formation of uniform crystal size. The crystallization process can be carried out for 6 to 24 hours, preferably for 16 hours, at a temperature of 40 ° C to -5 ° C, depending on the blend ratio and the type of feed oil. In order to obtain good low temperature stability of the filtrate, the preferred holding temperature before filtration of the crystallized oil is 18 ° C. or lower, since only liquid oil with good low temperature stability remaining in the liquid state can pass through the membrane. Should be Filtration of the oil is carried out through a membrane filter pressure of at least 400 kPa to 3000 kPa in a low temperature state, preferably in the temperature range of 5 ° C. to 15 ° C. From this process a filtrate having a high Iodine Value (IV) (70 or more) is obtained, leaving the liquid at a low temperature of 6 ° C or lower.

The filtered oil obtained from the filtration step comprises 20% to 40% saturated fatty acids, 20% to 40% monounsaturated fatty acids, and 20% to 40% polyunsaturated fatty acids. The filtrate (high grade oil) is still liquid at a near-zero temperature.

If the feed oil was not purified prior to the blending and fractionation process (see FIG. 2), the filtrate and solid portion were degumming and quantified using a 0.1% concentration of phosphoric acid at 95 ° C. temperature and neutralization. It should be purified by limited bleaching with 1% neutral or acidic bleach. Neutralization via steam deodorization should be avoided to retain a lot of carotene and vitamin E in the oil. Preferred neutralization processes include short path distillation and chemical neutralization.

The final oil resulting from this process will contain cloud points below 6 ° C. and at least 300 ppm carotene and at least 400 ppm vitamin E.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the scope of the present invention is not limited thereto.
