Background technology
Tobacco waste refers to except the tobacco leaf with industrial usability, other positions of tobacco plant, as tobacco rod, cigarette root, fireworks, cigarette wooden fork, axillalry bud, beat top and pin leaf that leaf removes as tobacco waste, be usually discarded in field in a large number or store and go rotten.China is tobacco planting big country, just has such a tobacco waste just to have hundreds of thousands of ton to be wasted every year, causes the loss of resource and the pollution of environment.The comprehensive utilization of tobacco is proposed by state monopoly office very early, and two Conferences in 2015 especially environmentally friendly type manufacturing industry is had higher requirement, and the recycling of tobacco waste needs to introduce more scientific and technical content.
Pectin is a kind of natural polymers, and its basic structure is D-galactopyranosyluronic, usually exists with part esterification state, is extensively present in the cell walls of the root of higher plant (comprising tobacco), stem, leaf, fruit etc.Now, the raw material being used for extracting pectin mainly contains orange peel, sunflower plate, Pericarpium Mali pumilae, Watermelon rind, Pericarpium Kaki etc., and about paper, the report of extracting pectin from tobacco few, but show in tobacco by research, the pectin content particularly in offal enriches.The pectin extraction technology be used at present in tobacco has acid extraction method, ion-exchanger method, enzyme process, microwave method, salt extraction method etc., but is all short of to some extent in the rate of recovery, energy consumption cost, quick degree.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, thering is provided a kind of utilizes sudden strain of a muscle to put forward the method that technology extracts pectin from tobacco waste, extracts in pectin body process, reduce extraction time to expect to reach with tobacco waste for raw material, improve the extract yield of pectin, and reduce the object of process costs.
Consider the problems referred to above of prior art, according to an aspect disclosed by the invention, the present invention by the following technical solutions:
Utilize to dodge and put forward the method that technology extracts pectin from tobacco waste, it comprises the following steps:
Step one, preparation HCl solution, put into tobacco waste in it;
Step 2, to move on Chinese medicine flash extracter and brokenly extract 5-20min, after filtration, obtain muddy solution;
Step 3, turbid solution suction filtration, obtain pectin crude extract, add activated carbon decolorizing after removing filter residue, then cool for subsequent use;
Step 4, obtain white pectin with absolute ethanol washing, obtain canescence pectin by after this pectin vacuum-drying, then pulverized, obtain product.
In order to realize the present invention better, further technical scheme is:
According to one embodiment of the invention, in described step one, the configuration of HCl solution adopts to load ultrapure water in beaker, then add HCl solution preparation, and regulator solution pH=2.
According to another embodiment of the invention, the massfraction of described gac is 3-4%, and when bleaching temperature is 60 DEG C, decolouring 30min.
The present invention can also be:
According to another embodiment of the invention, in described step 4, dehydrated alcohol slowly adds, and slowly stirs simultaneously.
Compared with prior art, one of beneficial effect of the present invention is:
Of the present invention a kind of utilize to dodge put forward the method that technology extracts pectin from tobacco waste, extract in pectin the time that greatly can shorten extraction at tobacco waste, whole simple to operate; do not need mixed solvent, cost is low, is conducive to the protection of environment; the pectin productive rate obtained is high, and purity is high.
