Embodiment 1

[0055] To prepare the required peony flower water, use supercritical CO 2 Its concrete preparation method of fluid extraction method is as follows:

[0056] (1) get peony flower petals, pick out impurities;

[0057] (2) Put the petals of peony flowers in (1) into the extraction pool, and use CO 2 Repeatedly flush the equipment to discharge the air. When operating, first open the valve and the gas cylinder valve for air intake, then start the high pressure valve to increase the pressure, and then adjust the pressure reducing valve when the pressure rises to the predetermined pressure, adjust the separation pressure in the separator, and then open The vent valve is connected to the rotameter to measure the flow rate and adjust each valve to make the extraction pressure, separation pressure and CO passing through the extraction process 2 The flow rate is stable at the required operating conditions, the valve is half closed, and the valve is opened for full cycle operation, and ...

Embodiment 2

[0059] Prepare the required peony flower water, adopt its specific preparation method of rotary evaporation method as follows:

[0060] (1) Take 1L of the peony flower stock solution after filtration;

[0061] (2) Put the stock solution of peony flowers in a rotary evaporator for rotary dry distillation and form steam to obtain a condensate after condensation. The preparation process is as follows:

[0062] Connect the hose to the condensate faucet first, connect the vacuum hose to the vacuum pump, and then pour distilled water into the heating tank. Adjust the angle of the host to tilt freely within 0-45°C, turn on the condensate, connect the power to the host and connect the evaporating bottle (don't let go), turn on the vacuum pump to reach a certain degree of vacuum and release your hand. Adjust the height of the main unit: press down the pressure rod located at the bottom of the heating tank, adjust the radian left and right to reach the appropriate position, and the des...

Embodiment 3

[0064] Prepare the required peony flower water, adopt its concrete preparation method of distillation as follows:

[0065] (1) Get 1 kilogram of peony flower petals;

[0066] (2) Boil the pot until boiling, add flower petals, cook for 30 minutes and then turn off the heat. After the flower water is cooked, filter the flower dew and put it into a container that has been sterilized in advance.

Abstract

The invention belongs to the technical field of peony processing, and particularly relates to a low-cost and high-extraction efficiency extraction method for a peony flower stock solution. The extraction method comprises the following steps: harvesting peony petals; carrying out cryopreservation on the petals; carrying out enzyme deactivation and sterilization treatment; squeezing and standing, and taking the upper-layer liquid to obtain a peony petal stock solution first crude liquid; sterilizing and decoloring; and filtering, and filtering for the second time to obtain the peony flower stocksolution. According to the invention, the peony flower stock solution prepared by the method disclosed by the invention is strong in free radical resistance, does not pollute the environment to the greatest extent, and is most energy-saving; compared with other processes such as distillation, supercritical carbon dioxide, subcritical, biological fermentation and other disclosed production processes, the product provided by the invention has strong oxidation resistance and stability; and raw material resources are fully utilized, the process is simple and convenient, economic benefits are high, investment cost is low, residues are low, no waste water or waste gas is generated, and efficient industrialization is achieved.

Description

technical field [0001] The invention belongs to the technical field of peony processing, and in particular relates to a low-cost, high-efficiency extraction method for the stock solution of peony flowers. Background technique [0002] Peony is known as "the king of flowers, the national beauty and heavenly fragrance". Peony is not only an ornamental plant with high ornamental value, but also has great medicinal value. And with the research and development of peony seed oil products, the peony industry has developed rapidly, the planting of peony has also increased in a large area, and the number of peony flowers has also increased significantly. In order to make effective and full use of peony resources, further development and resource utilization of peony petals are required. The peony flower water obtained by pressing peony petals as a raw material has great use value, such as using it as a raw material for cosmetics or skin care products. [0003] There are not many re...
