A blood lipid lowering agent that functions through a same mechanism as berberine (e.g. berberine, one or more pharmacologically acceptable salts of berberine or a mixture thereof) and a blood lipid lowering agent that functions through a different mechanism than berberine (e.g. phytosterols, phytostanols, esters thereof or mixtures thereof) act synergistically to improve blood lipid profiles, for example, lowering total cholesterol, LDL-C or nonHDL-C, and triglyceride, and increasing the ratio of HDL-C to nonHDL-C. The two may be used in combination to treat or reduce the chance of contracting cardiovascular disease, hyperlipidemia, atherosclerosis, coronary heart disease, angina, cerebrovascular disease, stroke, overweight or obesity, diabetes, insulin resistance, hyperglycemia, hypertension, arrhythmia, diseases of the central nervous system, diseases of the peripheral nervous system and/or inflammation. The blood lipid lowering agent that functions through a same mechanism as berberine, with or without the blood lipid lowering agent that functions through a different mechanism than berberine, may also be used to control weight.

A food in which a plant sterol and/or plant stanol whose dissolution in water is difficult is stably dispersed homogeneously while suppressing any deposition or coagulation (ring formation) thereof; and a process for producing the same. An emulsifier of 6 to 16 HLB and a plant sterol are added to a food raw material in a weight ratio of 3:8 to 10:1 and heated at 110 DEG to 200 DEG C, thereby obtaining an intended food.

The invention relates to a process for producing a substantially stable dispersion without manufacturing aids, where the dispersion comprises at least one hydrophobic plant sterol and an aqueous material, wherein the plant sterol is selected from plant sterols and plant stanols. The process comprises mixing the plant sterol with the aqueous material to form a first dispersion, homogenizing the first dispersion to obtain a second dispersion of particles wherein the particle size of the hydrophobic plant sterol particles in the first dispersion and the second dispersion is from about 0.1 micron to about 100 microns. Optionally, the process may comprise heating the first dispersion prior to homogenizing, heating the second dispersion after homogenizing, or heating both. In one embodiment, the aqueous material comprises a beverage concentrate, which includes a juice concentrate, such as a citrus juice concentrate, e.g., an orange juice concentrate. In one aspect of this invention, in order to substantially avoid a powdery taste in the dispersion, the particle size of the plant sterol particles is from about 0.1 micron to about 30 microns and the majority of hydrophobic plant sterol particles within this range will be from about 0.2 microns to about 10 microns and will substantially follow a bell curve distribution.

The invention relates to a novel preparation method of a phytostanol ester by taking an ionic liquid as a catalyst. The technical scheme adopted by the invention is as follows: in the absence of solvents and in the presence of nitrogen, a fatty acid (saturated or unsaturated acid) and phytostanol are heated to 90 to 180 DEG C to be melted completely, and are added with a catalyst to be subjected to an esterification reaction for 1 to 15 hours by controlling the temperature between 90 DEG C and 180 DEG C; a hydroxy acid, the phytostanol and the catalyst are added to a benzene, toluene or xylene solvent, and are heated to 80 to 115 DEG C to be subjected to the esterification reaction for 5 to 20 hours at this temperature; and after the end of the reaction, the phytostanol ester is obtained by separation and purification. The ionic liquid used in the method does not pollute the environment, has no obvious corrodibility, and is easy to recycle and reuse; the conversion rate of the phytostanol is high; and the product is convenient to recover, and the operation is simple.

A fat continuous coating which is suitable for coating nutrition bars and other products, especially foods products, which include less saturated fat. The coating includes a lipid base having a phytosterol and/or phytostanol structurant, and up to 28 wt % or less saturated fatty acid moieties. The phytosterol or phytostanol serves to provide sufficient structure to the coating to obviate the need for the higher levels of saturated fats which such ingredients tend ordinarily to contain. The coating will advantageously include numerous other ingredients typically found in coatings, such as cocoa, strawberry powder, yoghurt powder, etc. The lipid base will typically comprise from 20-50 wt % of the coating, especially from 25-40 wt %. The lipid base of the coatings will typically include at least 5 wt % phytosterols and/or phytostanols, especially at least 10 wt % phytosterols and/or phytostanols, more preferably at least 15 wt % phytosterols and/or phytostanols.
