Embodiment 1

[0018] Step 1: Peony seeds are shelled and dried to form peony powder with a particle size of 32 mesh for later use. Put the peony powder in a pot for roasting at a temperature of 143°C for 54 minutes. Peeled peony powder Put the rapeseed into another pot for roasting, the roasting temperature is 153°C, and roast for 75 minutes, mix the roasted peony powder and rapeseed according to the mass ratio of 3:1, stir the mixture for 31 minutes, stop Stir, then put the mixture into a closed centrifuge, centrifuge for 30 minutes at a speed of 1000r / min, control the pressure in the closed centrifuge at 0.58Mpa, take out 320kg of the mixture and put it into the extraction kettle, start the extraction, the extraction temperature The temperature is 37°C, the extraction pressure is 27Mpa, and the extraction time is 135min. Close the extractor, check to ensure that it is tightly sealed, use a high-pressure pump to pump the liquid CO2 in the storage tank into the vaporizer, and enter the extra...

Embodiment 2

[0025] Step 1: Peony seeds are shelled and dried to form peony powder with a particle size of 30 meshes for later use. Put the peony powder in a pot for roasting at a temperature of 140°C for 49 minutes. Peeled peony powder Put the rapeseeds into another pot for roasting, the roasting temperature is 148°C, and roast for 77 minutes, mix the roasted peony powder and rapeseeds according to the mass ratio of 3:1, stir the mixture for 33 minutes, stop Stir, then put the mixture into a closed centrifuge, centrifuge at a speed of 1000r / min for 31 minutes, control the pressure in the closed centrifuge at 0.58Mpa, take out 330kg of the mixture and put it into the extraction kettle, start the extraction, the extraction temperature The temperature is 52°C, the extraction pressure is 26Mpa, and the extraction time is 144min. Close the extractor, check to ensure that it is tightly sealed, use a high-pressure pump to pump the liquid CO2 in the storage tank into the vaporizer, and enter it in...

Abstract

The invention discloses a preparation method for edible oil blended from peony seed oil and rapeseed oil. The method comprises drying, baking, supercritical extraction, molecular distillation, mixing, heating and stirring. The operating temperature is low, and the heating time is short, so that oil oxidization and rancidification caused by high temperature can be avoided; the separation degree and the yield of a product are higher; by molecular distillation, the acid value of oil can be reduced; the aims of efficient extraction and separation, no impurities and high extracted product are fulfilled; the method is simple in operating process and short in extraction time, the cost is lowered, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of edible oil, in particular to a method for preparing edible oil blended with peony seed oil and rapeseed oil. Background technique [0002] Peony seed oil is also rich in polyunsaturated fatty acids, and its nutritional value far exceeds that of olive oil, which is known as "the oil of human health". The content of linolenic acid is more than 200 times that of olive oil. Many indicators are also higher than other oil types. It is not easy to be oxidized and deposited on the walls of human blood vessels, coronary arteries and other parts of the heart. It is these components that make it an ideal edible oil because of its important role in medicine and nutrition. It is no exaggeration to say that the nutritional and health effects of peony seed oil are unmatched by other edible oils. There are few deep-processed products of peony seeds on the market, which greatly reduces the economic value of peony seeds in my cou...
