Embodiment 1

[0036] Embodiment 1: the preparation of bamboo cypress seed oil

[0037] Step 1: Take 100 jin of dried bamboo cypress seeds and grind them into 40-mesh fine powder;

[0038] Step 2: Put the crushed bamboo and cypress seed powder into a wooden barrel covered with wet gauze at the bottom, place the wooden barrel on an energy-saving water bath and steam for 20 minutes;

[0039] Step 3: Put the steamed bamboo and cypress fine powder in a fixed mold, manually press it into a fixed shape, put it into an extruder, use a 0-30MPa program to increase the pressure in an automatic mechanical device, and extrude for 25 minutes to produce oil;

[0040] Step 4: Leave the extruded oil to stand overnight, then filter under reduced pressure through a 4 micron sand core funnel to obtain bamboo cypress seed oil, which has a delicate smell and is a light yellow transparent liquid (light yellow clear and transparent oil).

[0041] The inventors found that in step 2, the steam cooking time is extre...

Embodiment 2

[0048] Embodiment 2: use embodiment

[0049] The bamboo cypress seed oil product obtained by the present invention has better dietotherapy effects, such as a certain antioxidant activity and blood pressure lowering effect. In order to verify the effect, the inventor has carried out the following experiments: three people with high blood pressure, including the inventor Zhang Shibi, ate The oil process:

[0050] Before cooking oil, the three blood pressures were: 150.8, 160.5, 160.0

[0051]Each person takes 5ml of the oil on an empty stomach every morning, and before going to bed at night, and eats the oil with vegetables or noodles at noon (the amount of oil used is 5ml), and each person takes one 20mg of nitrobenzene every day for the first week Nifedipine slow-release tablets, during which the blood pressure was tested every morning, and the blood pressure of the three people was: 138, 142, 139; from the second week, each person took a 20 mg nifedipine sustained-release ta...

Embodiment 3

[0052] Embodiment 3: DPPH method detects the antioxidative activity test of the bamboo cypress seed oil product that embodiment 1 obtains

[0053] 3.1: Preparation of DPPH stock solution

[0054] Take 5 mg of DPPH in a 25 ml volumetric flask, dilute to volume with DMSO, shake fully, prepare DPPH stock solution, and store in the dark.

[0055] 3.2: Preparation of DPPH application solution

[0056] DPPH stock solution and DMSO were prepared into DPPH application solution (10ml) according to the ratio of 1.8:8.2, mixed thoroughly, prepared into DPPH stock solution, and stored away from light.

[0057] 3.3: Absorbance measurement

[0058] (1) Take 5ml of DPPH application solution, measure its absorbance A0 at 519nm, and measure it in parallel three times.

[0059] (2) Take 5ml of DPPH application solution, add 40μl of bamboo cypress seed oil product sample, mix and shake thoroughly, let stand for 30min, measure its absorbance A at 519nm, and measure it in parallel three times. ...

Abstract

The invention provides a preparation method of Podocarpus nagi seed oil. Podocarpus nagi seeds are used as raw materials, and the Podocarpus nagi seed oil is prepared through the steps of crushing, steaming, extruding, standing, filtering and the like. The oil yield of the preparation method can reach 90 percent. The Podocarpus nagi seed oil obtained by the preparation method contains rich activesubstances such as oleic acid, linoleic acid, arachidic acid, eicosenoic acid, alpha-linolenic acid, eicosandienoic acid, vitamin E and flavone, wherein the total content of unsaturated fatty acid exceeds 75 percent; the content of total flavone reaches up to 4.23 percent; the content of vitamin E reaches up to 2.11mg / 100g. The Podocarpus nagi seed oil is edible, and has the efficacies of reducingblood pressure and blood fat, softening and expanding blood vessels, improving microcirculation, preventing heart and cerebral vessels, preventing cancer, improving impaired vision and the like.

Description

technical field [0001] The invention relates to the technical field of vegetable oil preparation, in particular to a preparation method and application of bamboo cypress seed oil. Background technique [0002] According to statistics provided by the National Grain and Oils Information Center, since 1996, my country's edible oil imports have far exceeded domestic production, and China has become the world's largest importer of edible oil and its oil crops. At present, China's edible oil self-sufficiency rate is less than Four percent. In the near future, China's oilseeds mainly rely on rapeseed, peanut and linseed, etc., but this is also difficult to ensure the safe supply of oilseeds and edible oils in China, and it is necessary to open up new ways to seek long-term development. In 2011, my country's edible oil consumption reached 25.15 million tons, industrial and other consumption was 2.5 million tons, totaling 27.65 million tons, and the per capita annual consumption has ...
