Problems solved by technology

The roasting and frying process of Yuanbao maple seeds is time-consuming and laborious, and the cost is high. The process of pressing Yuanbao maple seeds to oil after roasting and frying has a low oil yield, and the prepared Yuanbao maple seed oil contains more impurities, which seriously affects The quality of the product, the pressing temperature is generally 85-90°C, which will damage the nutritional components of the oil to a certain extent, especially the impact on high value-added components such as nervonic acid is not yet clear
Therefore the present invention proposes a kind of supercritical CO 2 A method for extracting shelled maple seed oil to prepare maple seed oil, so as to solve the shortcomings of the existing industrial production of maple seed oil

Embodiment 1

[0024] Accurately weigh 250g of the ingot-shelled maple seed powder (seed moisture content is 6.59%, the same below) in the extraction kettle, adjust the pressure balance, heat the extraction kettle, separation kettle I, and separation kettle II to the set temperature, respectively 35MPa, 55°C, 2h, and at the same time turn on the cooling machine to refrigerate. The extraction kettle, separation kettle I, and separation kettle II are pressurized by a high-pressure pump, the pressures are 35MPa, 7.3MPa, 5.6-6.0MPa respectively, and the total extraction time is set to 2h. After the pressure reaches the set value, the circular extraction starts. After a certain period of time, the materials are discharged from the separation kettle I and the separation kettle II respectively, weighed and the yield is calculated. Supercritical CO in shelled maple ingot seed powder 2 The extraction yield was 92.21%. The physical and chemical indexes of Yuanbao maple seed oil were determined at th...

Embodiment 2

[0027] Accurately weigh 250g of maple ingot shell kernel powder in the extraction kettle, adjust the pressure balance, heat the extraction kettle, separation kettle Ⅰ, and separation kettle Ⅱ to the set temperature, which are 30MPa, 55°C, and 2h, and turn on the cooling machine at the same time . The extraction tank, separation tank I, and separation tank II are pressurized by a high-pressure pump, the pressures are 30MPa, 7.3MPa, 5.6-6.0MPa respectively, and the total extraction time is set to 2h. After the pressure reaches the set value, the circular extraction starts. After a certain period of time, the materials are discharged from the separation kettle I and the separation kettle II respectively, weighed and the yield is calculated. Supercritical CO in shelled maple ingot seed powder 2 The extraction yield was 93.18%. The physical and chemical indexes of Yuanbao maple seed oil were determined at the same time.

Embodiment 3

[0030] Accurately weigh 250g of maple ingot shell seed powder in the extraction kettle, adjust the pressure balance, heat the extraction kettle, separation kettle Ⅰ, and separation kettle Ⅱ to the set temperature, respectively 35MPa, 60°C, and 2h, and turn on the cooling machine at the same time . The extraction tank, separation tank I, and separation tank II are pressurized by a high-pressure pump, the pressures are 30MPa, 7.3MPa, 5.6-6.0MPa respectively, and the total extraction time is set to 2h. After the pressure reaches the set value, the circular extraction starts. After a certain period of time, the materials are discharged from the separation kettle I and the separation kettle II respectively, weighed and the yield is calculated. Supercritical CO in shelled maple ingot seed powder 2 The extraction yield was 94.85%. The physical and chemical indexes of Yuanbao maple seed oil were determined at the same time.
