Embodiment 1

[0019] 1. Raw materials:

[0020] Pick fully mature peony fruits, dry them in a dry and ventilated place for 6 days, and beat them with wooden sticks to make the peony seeds fall off naturally;

[0021] 2. Shelling:

[0022] Utilize the water separation method to select plump peony seeds, dry them, break them as a whole, separate the kernel shells, control the content of the seed shells in the kernels at 1 / 10, and crush the particles to six meshes;

[0023] 3. Cold pressing:

[0024] Send the raw materials into an oil press at room temperature, press for 8 hours under a pressure of 55MPa±2Mpa, the compression ratio of the oil press is above 24, and the temperature during the pressing process is within 60°C to obtain cold-pressed peony seed oil and seed cake;

[0025] 4. Filtration:

[0026] Put 1% silica gel H of cold-pressed peony seed oil into the chromatography column, add absorbent cotton to the top, add cold-pressed peony seed oil into the column, and filter under redu...

Abstract

The invention relates to a method for preparing blend oil and cold-pressing and extracting peony seed oil. The method comprises the following steps: collecting and dehulling seeds, cold-pressing and secondary-filtering, producing and filling the blend oil. The invention has a simple oil-extracting process and reduces the loss of active components in oil-extracting process. Cold pressing temperature is low so that phospholipid, pigment, and the like hardly enter oil, and the cold pressing oil has lighter color and lower phospholipid content and can achieve a new international four class oil standard only by mechanical filtration instead of any chemical refining. Cold pressing rap oil has high nutritive and healthcare values because thermosensitive alpha-tocopherol and phytosterols are fullyremained, active protein and other active components in peony seeds are remained so as to creates advantages for further developing new purposes of the seeds; no refining sewage is discharged in thecold pressing production process, therefore, the pollution controlling cost is lowered and the environmental protection is favorable.

Description

technical field [0001] The invention relates to the technical field of deep processing of peony products, in particular to a method for cold-pressing Gansu purple peony seed oil and a blending oil production technology, in particular to a method for extracting peony seed oil by cold pressing and preparing a blended oil. Background technique [0002] Gansu is an important birthplace of Chinese peony. Gansu purple spot peony is the second largest variety group of Chinese peony. It is widely cultivated in various parts of Gansu for its characteristics of cold resistance and drought tolerance, tall plants, and strong knot strength. For a long time, the peonies cultivated in various places are mainly for ornamental purposes and sales of seedlings. However, the development and utilization of deep-processed products of peony has lagged behind seriously, the added value of production is very low, and no industrial chain has been formed. In particular, only a small amount of peony see...
