Embodiment 1

[0041] The method of the present invention: in the mixing tank of 600g of rapeseed bee pollen purchased in Baikang Bee Industry, Xuancheng City, Anhui Province, add 8L of distilled water, control the temperature in the mixing tank to be 37°C, stir for 30 hours, place in a centrifuge at 5000r / m Centrifuge for 30 minutes, pour off the supernatant, and then dry the centrifugal pellet at 60°C for 48 hours to obtain 200 g of washed dried rape bee pollen, with a water content of 6% by mass; then crush it and pass through 200 After the mesh sieve, put it into the extraction kettle of the supercritical carbon dioxide extraction device, control the temperature at 50°C, the pressure at 40MPa, the flow rate of carbon dioxide at 30L / h, and extract for 2 hours; the conditions for the primary separation are temperature at 45°C and pressure at 8Mpa; The conditions of secondary separation are temperature 35°C and pressure 4-6Mpa. Finally, 50 grams of rapeseed bee pollen supercritical carbon d...

Embodiment 2

[0049] The method of the present invention: put 500 g of corn bee pollen purchased from Baikang Bee Industry in Xuancheng City, Anhui into a mixing tank, add 6 L of distilled water, control the temperature in the mixing tank to be 37 ° C, and after stirring for 30 hours, filter, remove the filtrate, and filter the precipitate After spray drying, the conditions are: the air inlet temperature is 200°C; after the spray speed is 5000ml / h, 150g of dried corn bee pollen after washing with water is obtained, and the water content is 6% by mass; then it is pulverized and passed through 100 After the mesh sieve, put it into the extraction kettle of the supercritical carbon dioxide extraction device, control the temperature at 55°C, the pressure at 35MPa, the flow rate of carbon dioxide at 25L / h, and extract for 2 hours; the conditions for the primary separation are temperature at 35°C and pressure at 7Mpa; The conditions of secondary separation are temperature 30°C and pressure 4-6Mpa. ...

Embodiment 3

[0057] The method of the present invention: in the mixing tank of 800 g of green vegetable bee pollen purchased from Baikang Bee Industry in Xuancheng City, Anhui Province, add 15 L of distilled water, control the temperature in the mixing tank to be 37 ° C, and after stirring for 36 hours, filter, pour the filtrate, and then After the filtered precipitate was vacuum-dried at 60°C for 52 hours, 264g of water-washed dried cabbage bee pollen was obtained, with a water content of 8% by mass; then it was pulverized and passed through a 200-mesh sieve and then loaded into a supercritical carbon dioxide extraction device. In the extraction kettle, the temperature is controlled at 45°C, the pressure is 30MPa, the flow rate of carbon dioxide is 35L / h, and the extraction is performed for 2 hours; the conditions for primary separation are temperature 25°C, pressure 8Mpa; the conditions for secondary separation are temperature 30°C, pressure 4-6Mpa. Finally, 68.86 grams of rape bee polle...

Abstract

The invention discloses a method for extracting fatty compounds from bee pollen, which comprises the following steps of: removing water soluble substances outside the pollen wall of the bee pollen; then, extracting the fatty compounds from the bee pollen by using a supercritical carbon dioxide extraction method. The method reduces production cost and the loss of a supercritical carbon dioxide extraction device through pretreatment steps, obviously increases the extraction rate and the yield of the fatty compounds from the bee pollen through supercritical extraction, and also obviously increases the content of fatty acid compounds in the obtained extract.

Description

technical field [0001] The invention relates to a method for extracting fatty compounds from bee pollen. Background technique [0002] Bee pollen is an irregular oblate mass formed by mixing the sperm cells of plants taken by bees, honey, bee gland secretions and saliva. Studies have shown that bee pollen not only contains many nutrients, but also has many medicinal substances related to life sciences. Bee pollen is rich in fatty compounds, among which linolenic acid and palmitic acid have the highest content, which have important nutritional and physiological functions. Therefore, the fatty compounds in bee pollen have high utilization value and development prospect. [0003] In the prior art, the method of extracting fatty compounds in bee pollen with organic solvents has disadvantages such as residual organic solvents, recovery of solvents, and easy oxidation of fatty compounds. Supercritical carbon dioxide extraction has the advantages of strong dissolving ability for...
