Problems solved by technology

[0004] At present, the extraction of sugarcane polysaccharides from sugarcane leaves and / or sugarcane tips requires steps such as soaking extraction, alcohol precipitation, and separation. The operation is complicated and the steps are cumbersome, and it is not suitable for industrial production.
Therefore, at present, there is no report on the rational industrial application of sugarcane leaves and / or sugarcane tips, and the sugarcane polysaccharide resources in sugarcane leaves and / or sugarcane tips have not been fully utilized.

Embodiment 1

[0046] Example 1 Preparation of Sugarcane Polysaccharide Extract

[0047] Harvest fresh sugarcane leaves, put them into a dehydration dryer and dry them to obtain 5 kg of dry sugarcane leaves, cut them into 1-2 cm pieces with a grass cutter, and collect the pieces; put the resulting pieces into an ultrasonic cleaning tank and wash them with water for 2 -3 times, collect the cleaned sugarcane leaves; put the sugarcane leaves into the extraction pot, add 75kg of water, stir evenly, heat to 80°C, keep warm for 120min, and extract. After the extraction is completed, the obtained mixture is centrifuged, and the centrifuged liquid is collected to obtain 75 kg of sugarcane polysaccharide extract. Pour the obtained sugarcane polysaccharide extract into a vacuum concentration tank to concentrate 10 times to obtain 7.5 kg of sugarcane polysaccharide extract concentrate.

[0048] The following method is used to identify the structure of sugarcane polysaccharide in the sugarcane polysacc...

Embodiment 2

[0050] Example 2 Preparation of Sugarcane Polysaccharide Extract

[0051] Take 5kg of sun-dried sugarcane leaves, cut them into pieces with a grass cutter; put the resulting pieces into an ultrasonic cleaning tank, wash them with water for 2-3 times, and collect the cleaned sugarcane leaves; put the sugarcane leaves into an extraction pot, and add 100kg of water, stir evenly, soak for 5 hours, heat to 100°C, keep warm for 60 minutes, and extract. After the extraction is completed, the obtained mixture is press-filtered, and the filtrate is collected to obtain 100 kg of sugarcane polysaccharide extract.

[0052] Use the following method to detect the content of sugarcane polysaccharide in the sugarcane polysaccharide extract obtained in this example: 100 kg of the obtained sugarcane polysaccharide extract is concentrated 320 times, and 10 times the volume of 95% ethanol is added to the concentrated solution, left to stand overnight, and centrifuged Take the precipitate, weigh ...

Abstract

The invention belongs to the technical field of plant extraction and discloses a preparation method and application of a sugarcane polysaccharide extract. The preparation method of the sugarcane polysaccharide extract provided by the invention comprises the following steps of: collecting sugarcane leaves and / or sugarcane tips to obtain a first product; mixing the first product with water in the mass ratio of 1: (10-50), extracting for 60-150 min at a temperature ranging from 70 to 100 DEG C, and collecting the extract to obtain the sugarcane polysaccharide extract. The preparation method of the sugarcane polysaccharide extract provided by the invention is few in steps and simple in preparation process; the sugarcane leaf and sugarcane tip resources are utilized sufficiently, and the obtained sugarcane polysaccharide extract contains rich sugarcane polysaccharides and can be applied to preparing sugarcane polysaccharide-containing beverages.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, in particular to a preparation method and application of a sugarcane polysaccharide extract. Background technique [0002] Sugarcane is an annual or perennial perennial tropical and subtropical herbaceous plant. It is an important raw material for the manufacture of sucrose, with a wide planting area and high economic value. The sugarcane stalks are upright, thick and juicy, often covered with white powder on the surface, the leaves are alternate, with small sharp teeth on the edges, and the flower spikes are compound racemes. Sugarcane tastes sweet, astringent, mild in nature, and non-toxic. It is rich in sugar, water, multivitamins, protein, calcium, iron and other substances. It has the effect of clearing away heat and promoting body fluid, and is very popular among people. In my country, sugarcane is mainly planted in Guangxi, Yunnan and other places, with an annual output of hundre...
