preparation example Construction

[0052] The preparation method of the oil composition disclosed in the invention comprises mixing phytosterol, oil, emulsifier and water and homogenizing;

[0053] Preferably, the following steps are included:

[0054] Step (1): Phytosterols are mixed with grease to form an oil phase;

[0055] Step (2): the emulsifier is mixed with the water phase to form the water phase;

[0056] Step (3): oil phase and water phase are mixed, preferably, carry out shear homogenization and / or high-pressure homogenization;

[0057] The homogenization refers to conventional physical homogenization, including but not limited to high-pressure homogenization, shearing homogenization, and the like.

[0058] In the composition of fatty acid residues of triglycerides in the oil, C12:0 fatty acids account for 20.0-40.0 wt% of the total fatty acids, and the ratio of C12:0 to C18:0 is 15:1-10:1.

[0059] The above-mentioned preparation method, wherein in weight percentage, phytosterol 0.05-2.0wt%, oil ...

Embodiment

[0080] Table 1 has listed the fatty acid composition of 13 kinds of oils and fats, and wherein grease 1~6 is the grease that has the fatty acid composition that the present invention limits, and promptly the content of C12:0 is 20~40% and the ratio of C12:0 and C18:0 is 15~10:1, which is formulated from grease A and B.

[0081] Table 2 is the nanoemulsion formulations of the examples and comparative examples using the grease in Table 1 as the oil base respectively, wherein the preparation steps of the nanoemulsion are as follows:

[0082] (1) phytosterols (brassicasterol 3.5%, campesterol 25.5%, stigmasterol 20% and sitosterol 51%) are fully dispersed in the described grease composition by 600rpm magnetic stirring, ultrasonic 60min, form clear and transparent oil phase;

[0083] (2) Fully disperse the emulsifier into water to form a uniform water phase;

[0084] (3) After the oil phase and the water phase are mixed together, first use 10000rpm normal pressure shearing for 2m...

Abstract

The invention provides an oil composition for improving the bioavailability of phytosterols, which comprises phytosterols, oils, water and emulsifiers. In the oil composition prepared by the invention, the phytosterol has a higher bioavailability.

Description

technical field [0001] The invention relates to an oil composition, which is used for improving the bioavailability of phytosterols. Specifically, it also discloses a preparation method for the oil composition. Background technique [0002] Phytosterol is one of the important by-products of oil processing. As a natural food functional factor nutrient, it has anti-inflammatory, anti-oxidation, and cholesterol-lowering effects. However, like many fat-soluble nutrients, it has poor water solubility, and it also has characteristics that general nutrients do not have, such as high melting point, crystallinity, and oil insoluble, which greatly limits its application in food. Utilization is extremely low. [0003] Whether in food or medicine, people often use synthetic sterol fatty acid esters to replace free sterols in various food systems, thereby improving the bioavailability of sterols. In addition to common sterol fatty acid esters, He et al. (FoodChemistry, 2016, 192: 557-5...
