Problems solved by technology

[0003] At present, the grid starworm products on the market are mainly dried products, which need further processing and cooking before eating, which not only requires certain cooking skills, but also takes a lot of time, which is extremely inconvenient
The protein fiber of the gridworm is relatively rich, so people with chewing disorders cannot effectively absorb its nutrition
Therefore, it is impossible to develop a kind of instant food that is convenient, tastes good, retains its nutritional value and has medicinal effects. There is a great market demand

Embodiment 1

[0040] This embodiment provides a method for preparing the polysaccharide of the naked square star insect, the preparation method comprising the following steps:

[0041] (1) Take fresh naked star worms, the body weight of the selected star worms is 15g, remove silt and viscera and clean them, and then homogenate to obtain a homogenate;

[0042] (2) Add deionized water at 105°C to the homogenate obtained in step (1), the volume ratio of the homogenate to deionized water is 1:3, extract for 5.5 hours, filter to remove insoluble components, and then vacuum concentrate the filtrate to the original 1 / 4 of the volume, and then add absolute ethanol accounting for 4 times the volume of the filtrate to the filtrate, let it stand overnight, then centrifuge at a temperature of 6°C and a speed of 7500rpm for 6min, pour out the supernatant and collect the precipitate ;

[0043] (3) Wash the precipitate obtained in step (2) with absolute ethanol for 3 times, then centrifuge, collect the was...

Embodiment 2

[0046] This embodiment provides a method for preparing the polysaccharide of the naked square star insect, the preparation method comprising the following steps:

[0047] (1) Take fresh naked star worm, the weight of the selected star worm is 12g, remove the sediment and viscera and wash, then homogenate to obtain homogenate;

[0048] (2) Add deionized water at 100°C to the homogenate obtained in step (1), the volume ratio of the homogenate to deionized water is 1:2, extract for 5.0 hours, filter to remove insoluble components, and then concentrate the filtrate in vacuum to the original 1 / 4 of the volume, then add absolute ethanol accounting for 4 times the volume of the filtrate to the filtrate, let it stand overnight, then centrifuge at a temperature of 5°C and a speed of 7000rpm for 5min, pour out the supernatant and collect the precipitate ;

[0049] (3) Wash the precipitate obtained in step (2) with absolute ethanol for 2-3 times, centrifuge again, collect the washed pre...

Embodiment 3

[0052] This embodiment provides a method for preparing the polysaccharide of the naked square star insect, the preparation method comprising the following steps:

[0053] (1) Take fresh naked star worms, the body weight of the selected star worms is 10-15g, remove the sediment and viscera and clean them, and then homogenate to obtain a homogenate;

[0054] (2) Add deionized water at 95°C to the homogenate obtained in step (1), the volume ratio of the homogenate to deionized water is 1:2, extract for 4.5 hours, filter to remove insoluble components, and then vacuum concentrate the filtrate to the original 1 / 4 of the volume, then add absolute ethanol accounting for 4 times the volume of the filtrate to the filtrate, let it stand overnight, then centrifuge for 4min at a temperature of 4-6°C and a speed of 6500rpm, pour out the supernatant and collect sediment;

[0055] (3) Wash the precipitate obtained in step (2) twice with absolute ethanol, centrifuge again, collect the washed...

Abstract

The invention relates to the technical field of medicines, in particular to a preparation method and application of sipunculus nudus polysaccharide. The method comprises the following steps: processing sipunculus nudus to extract polysaccharide, and mixing the polysaccharide with a sipunculus nudus extract, turmeric powder, sodium bicarbonate, citric acid and maltodextrin to prepare effervescent tablets. The new application of sipunculus nudus polysaccharide is explored, the sipunculus nudus polysaccharide is prepared into effervescent tablets convenient to carry and eat, the additional valueof sipunculus nudus is increased, and the preparation method is simple in process and suitable for large-scale production.

Description

【Technical field】 [0001] The invention belongs to the technical field of medicines, and in particular relates to a preparation method and application of polysaccharides of Acarina chinensis. 【Background technique】 [0002] Sipunculus nudus L., also known as Sipunculus nudus L., is also known as Sipunculus nudus L., commonly known as sandworm, and is known as "Marine Cordyceps". It is not only delicious and nutritious, but also an important medicinal and edible seafood. Its medicinal value has been recorded in various herbal medicines in my country: "Chinese Medicinal Animals" records that it invigorates the spleen and cures nocturia; "Marine Drugs and Effective Prescriptions" records that it clears lung heat and eliminates phlegm and cough; "South China Sea Marine Medicinal Biology" It is recorded that it clears the lungs, treats tooth swelling and pain, and can replace the traditional Chinese medicine Cordyceps sinensis; "Chinese Medicinal Marine Biology" records that it nou...
