Problems solved by technology

[0004] In 2006, Arjen Bot et al. found that mixtures of phytosterols and their esters can form transparent organic gels in vegetable oils, such as dihydrocholesterol, cholesterol, β- Sitosterol, stigmasterol, γ-oryzanol, etc., especially the mixed system of β-sitosterol and γ-oryzanol, can form fine fibrous structures in sunflower oil under the action of shear force, for example, in 5- Colloidal structure can be formed at 10°C, the surface of the colloid is smooth, but the shape is not stable
[0007] Although the above studies have paid attention to the reduction of trans fats and other factors affecting health in special oils and fats to varying degrees, they have not mentioned that by adding sterol saponins and phytosterols ( The method and application research of edible oil production by the bonded method of ester)

Embodiment 1

[0029] 1%-8% diosgenin (purity 98%), mixed into oil and stirred at a specific temperature of 90-100°C until a transparent solution is obtained. Add soybean oil and dioscin in a 25ml small beaker, the total mass is 15g, wherein the diosgenin content is variable. The preparation conditions are: stirring until the temperature reaches 100°C; continuous stirring for 15 minutes to obtain a transparent solution; rapid cooling of the solution at a temperature of -40°C, stirring at a speed of 120r / min for 90s; static storage at room temperature solution for 3 days;

[0030] Table 1 shows the results of measuring the hardness of this solution containing different amounts of diosgenin.

[0031] Table 1

[0032]

[0033] It can be seen from this table that when the content of diosgenin is increased, the hardness decreases first and then increases.

Embodiment 2

[0035] The solubility of diosgenin and β-sitosterol in soybean oil was better elucidated by a series of dissolution experiments. The other constant conditions in these experiments have been illustrated in Example 1, except that diosgenin was added to the oil and β-sitosterol to achieve a total content of 6%; the mass ratio of diosgenin and β-sitosterol was used as a variable (listed in the table below).

[0036] Table 2 shows the hardness results of the solutions containing different amounts of diosgenin and β-sitosterol. Experiments 1 to 4 are comparative experiments.

[0037] Table 2

[0038]

[0039] This series of experiments clearly demonstrated a synergistic effect of enhancing texture when these two substances were co-dissolved in soybean oil.

Embodiment 3

[0041] In this series of experiments, the storage days of the product after cooling: 1-3-6 days,

[0042] The total content of diosgenin and β-sitosterol is 6%, and other constant conditions have been clarified in Example 1. The texture is measured at room temperature, and the results are shown in the following table:

[0043] table 3

[0044]

[0045] It can be seen from this table that as the storage days increase, the hardness shows a decreasing trend.

Abstract

The invention discloses an edible oil and fat product adopting bonded materials of sterol saponin and phytosterol ester as raw materials. The bonded materials of the sterol saponin and the phytosterol ester are added in edible oil and fat base stocks to prepare the edible oil and fat product. The edible oil and fat product reduces the content of the saturated fat product, effectively solves the technical problems that the edible oil and fat depend on solid fat such as trans fat and saturated fat to provide crystal structures, and improves the health value of the edible oil and fat product.

Description

technical field [0001] The invention belongs to the technical field of edible oil products and their processing. In particular, it relates to an edible oil product which uses a bonded compound of sterol saponin and phytosterol ester as a raw material. Background technique [0002] The fat base material of special oils such as margarine was mostly animal fat in the early stage. At the beginning of the 20th century, lard was used and mixed with cottonseed oil or peanut oil as the base oil. With the emergence of vegetable oil hydrogenation technology, hydrogenated fats are more used in the production of margarine and shortening, and the trans fat in it makes the margarine have a higher melting point and stability. However, a large number of studies have shown that trans fats affect the composition of lipoproteins in human cell membranes, increasing the risk of heart disease and various metabolic syndromes. At present, 2.3 billion people in the world suffer from metabolic syn...
