Problems solved by technology

One is that the whole grains with shells are crushed and eaten directly or mixed with other foods. The added value of this utilization method is not high; the other is that the whole grains with shells are crushed and the oil is extracted by pressing or supercritical CO2 fluid constant pressure extraction. , the yield of the oil obtained in this way is low, the color is deep, and the quality is poor; the third is to use the water enzymatic method to get the oil after shelling, this utilization method has not only lost the nutrients and biologically active substances in the hemp seed shell, Water-soluble nutrients and biologically active substances in the kernel are lost

Embodiment 1

[0015] Take 500 g of hemp seed powder that has been crushed to 100 meshes and has a moisture content of 6%, put it into a 1L extraction tank, and set the supercritical CO2 extraction temperature to 35°C. Extract at 25MPa extraction tank pressure and 15MPa separation tank pressure for 45min, then raise the extraction tank pressure to 35MPa, reduce the separation tank pressure to 10MPa, and continue the extraction for 45min. During this period, the extract was separated every 15 minutes, wherein the first separated extract was about 10g heavy and milky, and the last separated extract was about 15g heavy and dark green. The middle section of the extraction time (15 -75min) about 110g of the extracted extract is heavy and clear golden yellow, which is high-quality hemp oil. The extraction yield of hemp seed oil under this experimental condition is 27%, wherein high-quality hemp oil accounts for 22%; The hemp seed residue is further puffed to obtain 360 g of fluffy light brown def...

Embodiment 2

[0017] Get 460g of hemp seed powder that has been crushed to 80 meshes and has a moisture content of 8%, put it into a 1L extraction tank, and set the supercritical CO2 extraction temperature to 35°C. Extract at 20MPa extraction tank pressure and 12MPa separation tank pressure for 60min, then raise the extraction tank pressure to 30MPa, reduce the separation tank pressure to 8MPa, and continue the extraction for 60min. During this period, the extract was separated every 20 minutes, wherein the first separated extract was about 12g heavy and milky, and the last separated extract was about 15g heavy and dark green. The middle extraction time (20 -100min) about 100g of the separated extract is heavy and clear golden yellow, which is high-quality hemp oil. The extraction yield of hemp seed oil under this experimental condition is 27.6%, wherein high-quality hemp oil accounts for 21.7%; The hemp seed residue is further puffed to obtain 330 g of fluffy light brown defatted hemp see...

Embodiment 3

[0019] Get 600g of hemp seed powder that has been crushed to 120 meshes and has a moisture content of 7.5%, put it into a 1L extraction tank, and set the supercritical CO2 extraction temperature to 38°C. Extract at 20MPa extraction tank pressure and 18MPa separation tank pressure for 60min, then increase the extraction tank pressure to 32MPa, reduce the separation tank pressure to 10MPa, and continue the extraction for 45min. During this period, the extract was separated every 15 minutes, wherein the first separated extract was about 12g heavy and milky, and the last separated extract was about 20g heavy and dark green. The middle extraction time (15 -75min) the about 136g weight of the extracted extract that is separated, is limpid golden yellow, and this is high-quality hemp oil. The extraction yield of hemp seed oil under this experimental condition is 28%, wherein high-quality hemp oil accounts for 22.67%; The hemp seed residue is further expanded to obtain 420 g of fluff...

Abstract

The invention discloses a processing and utilizing technology for hemp seeds with shells. The processing and utilizing technology comprises the following steps: firstly, carrying out vacuum drying onhemp seed raw materials, and then cooling, crushing and sieving; secondly, filling an extraction kettle of supercritical carbon dioxide extraction equipment with treated hemp seed powder, then carrying out boosting extraction and decompressing separation, fractionally collecting grease extracted at different stages during extraction and separation, and finally, carrying out rapid pressure relief puffing treatment on degreased residues. According to the processing and utilizing technology disclosed by the invention, a supercritical ERYA fluid variable pressure extraction technology is combinedwith a rapid pressure relief puffing treatment technology, so that hemp seed oil has the advantages of high yield, good quality and short extraction time; in addition, nutritional ingredients in the hemp seed oil and bioactive substances are sufficiently retained, and particularly degreased hemp seed powder is subjected to puffing treatment for facilitating subsequent further processing and utilization; the processing and utilizing technology is a processing method with the advantages of simplicity, high efficiency, safety, greenness and energy conservation for the hemp seeds with the shells.

Description

technical field [0001] The invention relates to a processing and utilization technology of hemp seeds, in particular to a method for manufacturing high-quality hemp seed oil and high-activity defatted hemp seed powder by using supercritical CO2 fluid pressure swing processing technology. Background technique [0002] Hemp seeds are the dry mature seeds of the Moraceae plant cannabis, also known as hemp seeds, hemp, and thread hemp seeds. Hemp seeds are recognized as the most concentrated, complete and balanced source of essential amino acids and essential fatty acids in the plant kingdom. Hemp seeds contain 25-35% oil, 20-25% protein, 20-30% dietary fiber, and are also rich in biologically active substances, vitamins and minerals, such as: phytosterols, chlorophyll, vitamin C, vitamin B1, β - Carotene, riboflavin, calcium, magnesium, iron, potassium, phosphorus, etc. are excellent raw materials for the production of health food, medicine, cosmetics and high-grade nutritiona...
