Embodiment 1

[0027] Example 1. A method for preparing a CLNA-rich tulou seed oil nanoemulsion, followed by the following steps:

[0028] 1). Preparation of Trichosanthes seed oil:

[0029] Under the conditions of 30MPa and 35°C, supercritical extraction of carbon dioxide to obtain the tulou seed oil;

[0030] 2). Weigh each component by weight percentage:

[0031] 5 parts of trichosanthes seed oil, 2.5 parts of polyoxyethylene sorbitan monooleate, 5 parts of ethanol, 87.5 parts of distilled water.

[0032] 3). At a temperature of 25°C, first mix the above-mentioned trichosanthes seed oil, polyoxyethylene sorbitan monooleate and ethanol evenly; then keep the temperature of 25°C, and under the stirring condition (40~80 rpm / Minutes) slowly drip (60-100 drops / min) of distilled water; get colostrum;

[0033] 4) Homogenize the colostrum in a high-pressure homogenizer at 60 MPa for 3 minutes to obtain a milky and uniform CLNA-rich trichosanthes seed oil nanoemulsion with a particle size of about 120 nm.

Abstract

The invention discloses trchosanthes kiriowii oil nanometer emulsion rich in conjugated linolenic acid, comprising the following components by weight percent: 1-20 percent of surfactant, 3-10 percent of cosurfactant, 5-20 percent of trchosanthes kiriowii oil and the balance distilled water. The invention also discloses a method for preparing the nanometer emulsion, comprising the following steps of: (1) weighing the components according to the weight percents; (2) mixing the surfactant, the cosurfactant and the trchosanthes kiriowii oil at a temperature of 23-27 DEG C and then dropwise addingthe distilled water when stirring the mixture to obtain primary emulsion; and (3) homogenizing the primary emulsion in a high-pressure homogenizer at 40-80MPa to obtain the trchosanthes kiriowii oilnanometer emulsion rich in conjugated linolenic acid. The trchosanthes kiriowii oil nanometer emulsion rich in conjugated linolenic acid has the advantages of good stability and nice taste.

Description

Technical field [0001] The invention relates to an oil-in-water nanoemulsion of trichosanthes seed oil rich in conjugated linolenic acid, and a preparation method and application thereof. Background technique [0002] Trichosanthes kirilowii Maxim. (Trichosanthes kirilowii Maxim.) has long been recorded in ancient Chinese medical books, and its fruits, seeds and roots can be used as medicine. Trichosanthes seeds have the effects of clearing the lungs, resolving phlegm, and moistening the intestines. In addition to its medicinal effects, the edible function of the edulis has also been gradually developed. In Anhui, Zhejiang and other places, it has been used as a fried snack. According to the modern nutritional analysis method, it is determined that the tea plant seeds are rich in nutrients, containing a large amount of potassium, magnesium, calcium, vitamin E, and high content of protein and oil, especially its oil contains up to 37% of a kind called The fatty acid component of...
