Abstract
The invention discloses an extraction method of purple sweet potato anthocyanin, which comprises the steps of cleaning and crushing the purple sweet potato, drying to constant weight and grinding into powder; adding the purple sweet potato powder into an acidification ethanol solution, and performing ultrasonic-assisted extraction to obtain extract liquid; filtering the extract liquid to obtain purple sweet potato anthocyanin filtrate; separating and concentrating the purple sweet potato anthocyanin filtrate and drying to obtain a product of purple sweet potato anthocyanin. The method disclosed by the invention has the advantages of cheap and easily available raw materials, simple and easy-to-control process, short preparation period, low production cost, low energy consumption, environmental friendliness and high product purity, thereby having good application prospects.
Description
Technical field
The invention belongs to functional active components extractive technique, relate to a kind of method of extracting anthocyanogen from purple potato.
Background technology
To be cyanidin(e) be combined into glycosidic link with sugar anthocyanogen, is present in the enchylema of flower, fruit, stem, leaf and root organ of plant, and it is presented by red, purplish red to different colours such as orchids.The structure of anthocyanogen is as follows:
Anthocyanogen has the feature the same with other natural flavone compounds, as stable carbon skeleton and the identical synthetic source of molecular structure.Anthocyanogen is good antioxidant at present, can vision enhancing, and anti-eye strain; Delay cranial nerve aging; The microangiopathy being caused by diabetes is had to therapeutic action; Strengthen cardio-pulmonary function; Prevention senile dementia.Pigment used in foodstuffs industry mostly is synthetic colour, nearly all has toxicity in various degree, and life-time service can endanger people's health, and natural pigment safety non-toxic, the feature that nutrition added valve is high, be subject to people's favor just day by day.
Summary of the invention
For solving the problem existing in above-mentioned existing synthetic colour technology, the object of the present invention is to provide a kind of technique simple, equipment requirements is low, the extracting method of eco-friendly purple potato anthocyanogen.
The present invention realizes the technical scheme that its object is taked: the extraction of a kind of purple potato anthocyanogen, comprises the steps:
(1) purple potato is cleaned and smashed, after oven dry, pulverize;
(2) acidifying ethanolic soln purple sweet potato powder being added, Ultrasonic Wave-Assisted Extraction, obtains vat liquor;
(3) vat liquor is filtered, obtain purple potato anthocyanogen filtrate;
(4) purple potato anthocyanogen filtrate is carried out to separation, concentrated, after being dried, obtain purple potato anthocyanogen product.
In step (1), described bake out temperature is 50-100 ℃, drying time 1-5h;
In step (2), described every 1L acidifying ethanolic soln adds purple sweet potato powder 50-200g;
In step (2), described acidifying ethanolic soln is used 0.1-5% hydrochloric acid to regulate acidity, and pH is 1-4, and hydrochloric acid, ethanol volume ratio are (0.1-2): 1;
In step (2), described ultrasonic power 100-800W, extraction temperature 20-80 ℃, extracting times 1-3 time, lixiviate total time 1-3h;
In step (3), described filtration filter screen used is 80-160 order;
In step (4), described method for separating and processing is processed for filtrate being carried out to the high speed centrifugation of 10000-20000rpm, collects supernatant liquid;
In step (4), described concentration method for rotation is concentrated lyophilize or spraying dry.
beneficial effect of the present invention:the prices of raw and semifnished materials that the present invention adopts are cheap, be easy to get, the succinct easily control of technique, and preparation cycle is short, and production cost is low, and less energy consumption is environmentally friendly, and product purity is high, therefore has good application prospect.
