Embodiment 1

[0031] A preparation method of blueberry seed oil, comprising the steps of:

[0032] (1) Wash the blueberry seeds with clean water, dry them, and squeeze them in an extruder to obtain blueberry seed oil and blueberry seed dregs, and place the blueberry seed oil at a constant temperature of 0°C for 40 minutes for later use;

[0033] (2) Extract the above-mentioned blueberry seed pomace with a 70% ethanol solution at 65°C for 2 hours, recover the ethanol, remove the water phase, and take the oil phase;

[0034] (3) Combine the above-mentioned blueberry seed oil and oil phase, decolorize with activated carbon, and filter to obtain the product.

[0035] The blueberry seed oil obtained in this example accounts for 6.5% by mass of the blueberry seeds; through gas chromatography analysis, its purity reaches 96%.

Embodiment 2

[0037] A method for preparing blueberry seed oil, the specific steps of which are basically the same as in Example 1, the difference being that petroleum ether is used for extraction in this example. The blueberry seed oil prepared in this example accounts for 6% by mass of blueberry seeds; through gas chromatography analysis, its purity reaches 96%.

Embodiment 3

[0039] A preparation method of blueberry seed oil, comprising the steps of:

[0040] (1) Crush: Crush the blueberry seeds to 50-55 mesh, and add 260g of blueberry seed powder to each liter of reactor;

[0041] (2) Extraction: extraction pressure is 32MPa, extraction temperature is 39°C, CO 2 The flow rate is 32Kg / h,

[0042] The separation pressure is 8MPa, the separation temperature is 33°C, and the extraction time is 1.6h;

[0043] The blueberry seed oil obtained in this example accounts for 9% by mass of blueberry seeds; through gas chromatography analysis, its purity reaches 98%.

Abstract

The invention discloses blueberry seed oil and as well as a preparation method and an application thereof. The blueberry seed oil is prepared by the following one or more extraction methods: an organic solvent leaching method, a supercritical extraction method and a physical squeezing method; a blueberry seed oil preparation is prepared from blueberry seed oil described above as an active ingredient, and substances having healthy function and / or acceptable adjuvants of health food; and the invention discloses an application of the blueberry seed oil and the blueberry seed oil preparation in preparing health foods having the effects of improving eyesight and reducing blood lipid. Since three methods, namely, the physical squeezing method, the organic solvent leaching method and the CO2 supercritical extraction method are used alone or in combination, the yield of the blueberry seed oil is ensured; the method is high in production efficiency and oil yield, low in cost and is economic and feasible and the technology is reliable; and the method has wide applicable range and is used in large-sized, medium-sized and small-sized businesses.

Description

technical field [0001] The invention relates to a preparation method of vegetable seed oil, in particular to a blueberry seed oil and its preparation method and application. Background technique [0002] Blueberry is a popular fruit. In recent years, more and more people have recognized the medicinal and nutritional value of blueberry. At present, my country's blueberry industry has entered a new development period, and the planting industry, wine industry, and beverage industrial processing have developed to a certain scale. However, in the fresh blueberry fruit, the content of blueberry seeds is about 3%, about thousands of tons of blueberry seeds are produced every year, and most of them are discarded; this not only causes a huge waste of resources, but also pollutes the environment. Yet up to now, the research to blueberry seed and its exploitation are few in the world, therefore, the research to blueberry seed and how to make full use of blueberry seed that is to the c...
