Abstract
The invention discloses a kitchen waste fermentation product fulvic acid and a preparation method thereof. A biological fulvic acid product is prepared by taking kitchen waste fermentation products as raw materials and applying a PH (Potential of Hydrogen) adjusting extraction process and an ion exchange resin purification process in a combined way. The preparation method comprises the steps: carrying out fermentation treatment on kitchen wastes, and then, converting the kitchen wastes into biological humic acid through biological degradation; next, carrying out PH adjusting extraction to preliminarily remove a greatly number of impurities; further purifying an ion exchange resin column on a crude extracting solution to remarkably remove saline ions, colloids and other impurities to obtain a high-purity biological fulvic acid product. The kitchen waste fermentation product fulvic acid product prepared by using the method is simple, convenient and feasible, high in purity and good in product performance.
Description
Technical field
The present invention relates to a kind of product that kitchen castoff is starting raw material and preparation method thereof of take, specifically relate to and a kind ofly take the biological xanthohumic acid that the kitchen castoff tunning is raw material and produce and preparation method thereof.
Summary of the invention
?xanthohumic acid is a component in humic acids, can from the humic acids in coal source, separate and obtains or directly extract from peat, weathered coal, also can utilize the method for biotechnology to take agricultural tankage, kitchen castoff and be produced as raw material.Xanthohumic acid is a plant growth regulators, and the energy Promoting plant growth, play an important role to drought resisting, is a kind of comparatively ideal antitranspirant, can improve the effects such as plant stress-resistance ability.In addition, a large amount of kitchen castoff of the annual generation of China, cause serious problem of environmental pollution, and its fermentation is transformed and produces xanthohumic acid, solves environmental problem, can produce again efficient xanthohumic acid product, meets the requirement of environment sustainable development.
At present, fermentation produces the thing xanthohumic acid because of advantages such as its molecular weight are little, functional group is many, enjoys industry to pay close attention to.Because fermentation produces thing xanthohumic acid kind product composition complexity, often contain a large amount of impurity in the crude extract obtained, as the material in protein, colloid, grease and other raw materials or by the macromolecular substance that ferments and produce, cause extract to have the problems such as content is lower, proterties is poor, be difficult to meet the requirement of product marketization, how fermentation is produced to the xanthohumic acid crude extract and carry out purifying, improving its purity and product performance is to need the problem solved.
The object of the present invention is to provide a kind of comprehensive utilization kitchen castoff resource, turn waste into wealth, manufacture goes out the method for biological xanthohumic acid.
Another object of the present invention is to provide a kind of extraction and purifying process that is applied to the kitchen castoff tunning, prepare the method for the biological xanthohumic acid product of high purity.
For achieving the above object, the invention provides the fermentation of a kind of kitchen castoff and produce thing xanthohumic acid extract, this biology xanthohumic acid extract be take the kitchen castoff tunning and is made as raw material, and prepared by the following method by the kitchen castoff tunning:
Take kitchen castoff as starting material, in biochemical processor through 60～80 ℃, 8～10 hours rapid high-temperature aerobic fermentations, add ten thousand/ the biological humic transforming agent, transform and generate tunning through biological degradation.
For reaching above-mentioned another purpose, the present invention also provides a kind of combined utilization soda acid to adjust the preparation method of PH extraction and ion-exchange resin purification technique, and the method comprises the steps:
(1) take kitchen castoff tunning raw material, add suitable quantity of water, with 1% sodium hydroxide solution adjust pH, after decocting extraction, collect filtrate; Filter residue adds suitable quantity of water, extracts for the second time, collects filtrate, merges filtrate twice.Adjust pH with dilute hydrochloric acid, standing, centrifugal, collect the acid out supernatant liquor, standby.
(2) suitable ion exchange resin is filled to pillar, prepare kitchen castoff filtration post;
(3) by the crude extract of above-mentioned kitchen castoff tunning with certain flow velocity upper prop, and collect effluent liquid;
(4) use pure water with certain flow rate wash-out pillar, until detect without xanthohumic acid;
(5) elutriant of (4) step gained is merged, concentrated, drying, obtain the kitchen castoff fermentation and produce the thing xanthohumic acid.
The present invention has following effect:
(1) kitchen castoff raw material used is domestic refuse, and catering industry rubbish is carried out to cycling and reutilization, and environment protection is had to certain effect, can produce again efficient biological xanthohumic acid product;
(2) the kitchen castoff tunning, after extraction and purification technique, has effectively been removed the impurity components such as colloid, salt ion, has greatly improved purity and the product characteristics of biological xanthohumic acid product, and its biological xanthohumic acid content is more than 80%.
