Embodiment 1

[0014] 1. Material selection, impurity removal and drying: Wash the celery seeds with clean water to remove dust, soil and other impurities, and then put them in the sun to dry until the moisture content reaches 4%.

[0015] 2. Microwave: Put a certain amount of celery seeds in a microwave oven, and use 700W microwave treatment for 60s.

[0016] 3. Oil extraction: Select a slag outlet with a nozzle diameter of 4 mm, assemble a low-temperature press (purchased from IBG, Germany, model KOMET-CA59G), and preheat the low-temperature press for about 30 seconds to keep the temperature of the slag outlet At 56°C, the controlled rotation speed is 18.6rpm, and low-temperature pressing is carried out.

[0017] 4. Filtration: the oil pressed at low temperature is centrifuged (3500r / min, 15min), filtered with three layers of gauze to obtain clean celery seed oil, and the celery seed oil yield is 22.98% at this moment.

[0018] Volatile components of celery seed oil see figure 1 and Tabl...

Embodiment 2

[0025] 1. Material selection, impurity removal and drying: Wash the celery seeds with clean water to remove dust, soil and other impurities, and then put them in the sun to dry until the moisture content reaches 5%.

[0026] 2. Microwave: Put a certain amount of celery seeds in a microwave oven, and use 400W microwave treatment for 120s.

[0027] 3. Oil extraction: Select a slag outlet with a nozzle diameter of 4mm, assemble a KOMET-CA59G low-temperature press, preheat the low-temperature press for about 30 seconds, keep the temperature of the slag outlet at 55°C, control the speed at 16.3rpm, and perform low-temperature press.

[0028] 4. Filtration: the oil pressed at low temperature is centrifuged (3500r / min, 15min), filtered with three layers of gauze to obtain clean celery seed oil, and now the celery seed oil yield is 19.88%.

Embodiment 3

[0030] 1. Material selection, impurity removal and drying: Wash the celery seeds with clean water to remove dust, soil and other impurities, and then put them in the sun to dry until the moisture content reaches 5%.

[0031] 2. Microwave: Put a certain amount of celery seeds in a microwave oven, and use 550W microwave treatment for 90s.

[0032] 3. Oil extraction: Select a slag outlet with a nozzle diameter of 4mm, assemble a KOMET-CA59G low-temperature press, preheat the low-temperature press for about 30 seconds, keep the temperature of the slag outlet at 60°C, control the speed at 27.6rpm, and perform low-temperature press.

[0033] 4. Filtration: the oil pressed at low temperature is centrifuged (3500r / min, 15min), filtered with three layers of gauze to obtain clean celery seed oil, and now the celery seed oil yield is 19.23%.

Abstract

The invention discloses a method for microwave assisted low temperature squeezing apium graveolens seed oil. According to the method, apium graveolens seeds with the water content of 4-6% are used as raw materials, and after microwave treatment, the apium graveolens seeds are subjected to squeezing, centrifugation and three-layer gauze filtration at the temperature of 55-65 DEG C, so that volatile contents and other fat soluble nutritional ingredients (such as vitamin E and A) in the obtained apium graveolens seed oil can be reserved to the greatest extent. Through adopting the method, trans-fatty acids, grease polymers and other harmful substances are avoided, and natural flavor and pure color of the oil product are kept; besides, no chemical residues exist, and the apium graveolens seed oil is safe, sanitary and pollution-free.

Description

technical field [0001] The invention relates to a microwave-assisted low-temperature pressing method for celery seed oil, which belongs to the technical field of oil processing. technical background [0002] Celery seed oil is obtained from the seeds of dicotyledonous plant celery (Apiumgraveolens L.) in the family Apiales. Celery seed oil is rich in volatile oils, and the aromatic components detected by GC-MS are mainly β-celerene, D-limonene, α-caryophyllene, etc., which have the effects of lowering blood pressure, lowering fat, and calming the nerves. Celery seed oil is mainly used for the deployment of perfumes, cosmetics, soaps, etc., and can also be used in the food industry as a food flavor. [0003] There are some deficiencies in the extraction of celery seed oil by traditional methods such as pressing and organic solvent extraction. The high temperature in the traditional hot pressing process will volatilize the aromatic components, and the obtained oil has a dark...
