Embodiment 1

[0028] Take 2 kg of rapeseed pollen (moisture content 5%) as raw material, add it into a 15L extraction tank, then feed liquefied petroleum gas into the extractor, and extract for 1 hour under the conditions of extraction temperature 20°C and extraction pressure 0.1Mpa Desolventization of bee pollen meal and mixed oil is carried out, and the solvent is compressed and recycled to obtain bee pollen meal and bee pollen oil, and the oil yield is 4.0% for the first time. Desolvation conditions of bee pollen meal: the degree of vacuum is 0.07Mpa, the temperature is 40°C, and the time is 0.5 hours. Mixed oil precipitation conditions: vacuum degree 0.08Mpa, temperature 40°C, time 0.5 hour.

[0029] Carry out the second extraction according to the first extraction conditions, the oil yield is 0.5%

[0030] The third extraction was carried out according to the first extraction conditions, and the oil yield was 0.3%.

Embodiment 2

[0032] Take 2 kg of rapeseed pollen (moisture content 5%) as raw material, put it into a 15L extraction tank, then feed liquefied petroleum gas into the extractor, and extract for 1 hour under the conditions of extraction temperature 40°C and extraction pressure 0.2Mpa Desolventization of bee pollen meal and mixed oil is carried out, the solvent is compressed and recycled to obtain bee pollen meal and bee pollen oil, and the first oil yield is 4.5%. Desolvation conditions of bee pollen meal: the degree of vacuum is 0.07Mpa, the temperature is 40°C, and the time is 0.5 hours. Mixed oil precipitation conditions: vacuum degree 0.08Mpa, temperature 40°C, time 0.5 hour.

[0033] The second extraction was carried out according to the first extraction conditions, and the oil yield was 0.4%.

[0034] The third extraction was carried out according to the first extraction conditions, and the oil yield was 0.1%.

Embodiment 3

[0036] Take 2 kg of rapeseed pollen (moisture content 5%) as raw material, put it into a 15L extraction tank, then feed liquefied petroleum gas into the extractor, and extract for 1 hour under the conditions of extraction temperature 50°C and extraction pressure 0.4Mpa Desolventization of bee pollen meal and mixed oil is carried out, and the solvent is compressed and recycled to obtain bee pollen meal and bee pollen oil, and the oil yield is 4.7% for the first time. Desolvation conditions of bee pollen meal: the degree of vacuum is 0.07Mpa, the temperature is 40°C, and the time is 0.5 hours. Mixed oil precipitation conditions: vacuum degree 0.08Mpa, temperature 40°C, time 0.5 hour.

[0037] The second extraction was carried out according to the first extraction conditions, and the oil yield was 0.3%.

[0038] The third extraction was carried out according to the first extraction conditions, and the oil yield was 0.1%.

Abstract

This invention provides a safe and high efficiency method for extracting bee pollen grease by using supercritical fluid. The method comprises: (1) adding bee pollen to an extractor, adding propane, butane or their mixture, and extracting under stirring; (2) removing the solvent from bee pollen and mixed oil, respectively; (3) recovering and recycling the solvents, and obtaining bee pollen and bee pollen grease. The method has such advantages as high efficiency, high extraction rate, short extraction time, low cost, low solvent consumption, and high product quality. The bee pollen grease can be used to treat cardiovascular diseases, inflammation and cancer, and can promote brain development.

Description

technical field [0001] The invention relates to a method for extracting bee pollen oil with a supercritical fluid, which belongs to the field of deep processing of natural products. Background technique [0002] Bee pollen is the pollen grains collected by bees from the anthers of flowering plants—the source of honey pollen by bees using their own special structure. After being mixed with nectar and saliva by bees, they are processed into irregular flat circles. The pollen baskets on the hind limbs of bees Carry clumps back to the nest. Bee pollen is a high-grade natural nutrient, known internationally as Perfect Foods, and is regarded as a promising food resource in the 21st century. The fat content in bee pollen accounts for 1% to 20% of its dry weight, generally about 5%. Although the fat content in bee pollen is not high, the proportion of unsaturated fatty acids in oil is generally high, mainly oleic acid, linoleic acid, and linolenic acid. The sum of the proportions ...
