Embodiment 1

[0025] A method for extracting lily polysaccharides, comprising the following steps:

[0026] (1) Raw material: choose plump musk lily bulb as raw material, after washing the soil on the surface of the lily bulb, peel off the scale from the lily bulb for subsequent use;

[0027] (2) Pretreatment: After the scales separated in step (1) are cut into 5mm segments, then add ethanol solution with 2 times the volume of the scales, soak for 1 hour, filter and take out 5% volume of the filtrate as the first eluate , after continuing to immerse for 22 hours, filter out all the filtrate to be the continued eluting liquid, combine the initial eluting liquid and the continuing eluting liquid, recycle and remove ethanol, and obtain the solid-liquid mixture as substance a; wherein, the volume concentration of the ethanol is 60%;

[0028] (3) Ultrasonic treatment: put the substance a described in step (2) into distilled water of 1.2 times the mass to obtain a mixed solution, put the mixed so...

Embodiment 2

[0035] A method for extracting lily polysaccharides, comprising the following steps:

[0036] (1) Raw material: choose plump musk lily bulb as raw material, after washing the soil on the surface of the lily bulb, peel off the scale from the lily bulb for subsequent use;

[0037] (2) Pretreatment: After the scales separated in step (1) are cut into 6mm segments, then add ethanol solution of 3 times the volume of the scales, soak for 1.5h, filter and take out 8% volume of the filtrate as the primary filter After continuing to immerse for 23 hours, filter out all the filtrates as the subsequent eluting liquid, combine the initial eluting liquid and the subsequent eluting liquid, recycle and remove ethanol, and the resulting solid-liquid mixture is used as substance a; wherein, the volume concentration of ethanol is 65% ;

[0038](3) Ultrasonic treatment: put the substance a in step (2) into distilled water twice the mass to obtain a mixed solution, put the mixed solution in an u...

Embodiment 3

[0045] A method for extracting lily polysaccharides, comprising the following steps:

[0046] (1) Raw material: choose plump musk lily bulb as raw material, after washing the soil on the surface of the lily bulb, peel off the scale from the lily bulb for subsequent use;

[0047] (2) Pretreatment: after the scales separated in step (1) were cut into 5.5mm segments, then add ethanol solution of 2.5 times the volume of the scales, soak for 1.2h, filter and take out 7% volume filtrate as initial After soaking the liquid for 22.5 hours, filter out all the filtrates as the continued draining liquid, reclaim and remove ethanol after combining the initial draining liquid and the continuing draining liquid, and obtain the solid-liquid mixture as substance a; wherein, the volume concentration of the ethanol is 64%;

[0048] (3) Ultrasonic treatment: put the substance a in step (2) into distilled water with 1.8 times the mass to obtain a mixed solution, put the mixed solution in an ultr...

Abstract

The invention provides an extraction method for lily polysaccharide, belonging to the field of food processing. The method comprises the following steps: firstly, by taking full musk lily bulbs as raw materials; cleaning and then removing scales; soaking the acquired scales into ethyl alcohol under a specific condition; extracting the treated substance in the manner of ultrasonic wave; performing enzymolysis treatment on the acquired substance by using self-prepared active fluid, thereby further extracting the polysaccharide in the lily bulbs; purifying the substance by utilizing neutral protease after enzymolysis. The lily polysaccharide acquired according to the treatment process combined with the steps is capable of completely keeping nutritional ingredients, and the extraction efficiency and purifying rate of the lily polysaccharide can be increased.

Description

【Technical field】 [0001] The invention relates to the field of food processing, in particular to a method for extracting lily polysaccharides. 【technical background】 [0002] Musk lily is a beautiful flower with extremely fragrant flowers and contains aromatic oils. It can be used as a spice. Its bulbs are spherical or nearly spherical, 2.5-5 cm high, with white scales. Both the stems and flowers have the functions of clearing away heat, detoxifying and moisturizing the lungs. It has the effect of relieving cough, and can be used to treat cough, hematuria, placental retention, and unknown swelling. Musk lily can be eaten and used as seasoning. Like onion and garlic, it belongs to the spice seasoning of bulbs. The bulb of musk lily is a famous health food. The fresh product can be used to make dishes. The scale leaves are sweet and slightly bitter. etc.; the flower has the effect of nourishing the lungs, clearing the fire, and calming the nerves, and is used for cough, dizz...
