Abstract
The invention discloses a microwave-assisted method for extracting peanut coat haematochrome. Natural pigments are strongly demanded in markets at home and abroad. Haematochrome is a pure nature pigment, can be widely used for coloring food and has medical treatment functions; resveratrol included in the haematochrome and also known as resveratrol has antiplatelet aggregation and anti-inflammatory, anti-allergic, antithrombotic and atherosclerosis effects, has preventive and therapeutic effects on coronary heart disease, ischemic heart disease and hyperlipidemia and also has antioxidant effect and effects of scavenging free radical and inhibiting tumor. According to the technical scheme adopted by the invention, a microwave-assisted method for extracting peanut coat haematochrome is characterized by comprising the following steps of: preparing raw materials, carrying out microwave-assisted extraction, carrying out secondary extraction, adopting a membrane filtering method, concentrating in vacuum, freezing and drying to obtain the product.
Description
Technical field
The present invention relates to a kind of method of utilizing microwave-assisted to extract the Testa arachidis hypogaeae haematochrome, belong to the biological extraction field.
Background technology
Food color is a kind of food of using for food color
Additive, be widely used in industries such as food, daily use chemicals, medicine.The pigment that uses mainly is synthetic food color at present, cost is low, but human body there is different injuries, carcinogenic, teratogenesis, mutagenic consequence are especially arranged, caused people's very big concern, developed country has made laws and has banned use of synthetic food color, China also bans use of synthetic food color in industries such as food, makeup, medicine, natural pigment is the pigment that directly extracts from plant, not only have no side effect, and have certain nutrient value, and natural pigment replaces synthetic colour to become inexorable trend, and the world market natural pigment is in short supply.
The domestic and international demand of natural pigment market is vigorous, and the Testa arachidis hypogaeae haematochrome is a kind of pure natural pigment, not only is widely used in food color, and has a medical therapy effect, the trans-resveratrol that it contains claims resvertrol again, has anti-platelet aggregation and anti-inflammatory, anti-allergic effects; Anti thrombotic action; The preventive and therapeutic effect of atherosclerosis and coronary heart disease, ischemic heart disease, hyperlipidemia; Anti-oxidant, as to remove free radical effect; Suppress the effect of tumour, though a small amount of research is arranged both at home and abroad, do not see the report of relevant products production.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art, extraction yield is low in the time of can not extracting or extract, and the waste resource increases cost.
The technical solution used in the present invention is: a kind of method of utilizing microwave-assisted to extract the Testa arachidis hypogaeae haematochrome is characterized in that step is:
1. feedstock production: Testa arachidis hypogaeae is cleaned with 60% ethanol water logging bubble, and the ethanol Testa arachidis hypogaeae aqueous solution of system;
2. microwave-assisted extracts: at room temperature, the adjusting microwave frequency is 2400-2500MHZ, and extracting power is that 200-300W carries out extracts active ingredients:
3. extract: adopt dehydrated alcohol as extraction agent, carry out secondary and extract.
4. filter: filter by membrane filter method;
5. concentrate: by vacuum concentration, obtain Testa arachidis hypogaeae haematochrome concentrated solution;
6. lyophilize forms product.
Ethanol Testa arachidis hypogaeae aqueous solution ratio in the described step 1 is 1: 3.
Microwave optimal frequency 2450MHZ in the described step 2, the extraction power optimized is 2501W.
The extraction solvent is 75% ethanol in the described step 3, and extraction time is 3min, and solid-liquid ratio (g/ml) is 1: 25.
Adopt the cellulosic ultrafiltration film in the described step 4, the control flow velocity further can also adopt reverse osmosis membrane to filter at 2-3 milliliter per minute.
Described step 5 is to carry out vacuum concentration by the counter-current temperature at 75 ℃, and pressure in vacuum tank is that the vacuum means of 90pa and employing is set to dry vacuum pump
Beneficial effect of the present invention has not only improved extraction yield greatly, and the pigment extraction yield is 96.32%, reduces extraction time, economizes on resources, and reduces cost
Physical and chemical index:
Pigment content (%): 〉=92
Heavy metal is (in Pb, mg/kg) :≤1.0
