Abstract
The invention relates to an extracting method for preparing chestnut shell brown pigment, belonging to biological product technology. It comprises following steps: employing chestnut shell as raw material, immersing and heating, dissloving brown pigment from chestnut shell, centrifuging for separation, collecting extracting liquid, extracting for 3- 4 times, condensing extracting liquid and adding alcohol for immersion, sucting and separating foreign substance and polysaccharide, recovering ethanol, filtering with microfilm, spray drying and getting brown pigment powder. The invention is characterized by abundant raw material, simple separation and purification process, high extraction rate, high purity, no pollution, safe and convenient application in food processing and weaving and dyeing, and outstanding performance price ratio.
Description
Technical field
A kind of extraction method prepares the method for fiber crops chestnut shell brown pigments, belongs to biological product technical field.Relating to fiber crops chestnut shell is raw material extraction method preparation fiber crops chestnut shell brown pigments.
Background technology
Natural pigment is good with its nontoxicity, stability, has advantages such as nutrition and pharmacological action simultaneously concurrently and is favored by people.
Fiber crops chestnut shell source is distributed in ground such as Fujian, Taiwan, Guangdong, Hainan, Guangxi, Yunnan for the exocarp of myrtle crow China ink [Syzygium cumimi (L.) Skeels].The medicinal sheep dung fruit by name of fiber crops chestnut (full fruit), different name are 10 years fruits, Ma Li, mountain Portugal, Fruit of Shortanther Syzygium.Its function is astringing for relieving or preventing asthma with curing mainly, and promotes the production of body fluid puckery intestines.Cure mainly phthisical cough, void is breathed heavily, and Tianjin wound is thirsty, rushes down protracted dysentery for a long time.
Summary of the invention
The purpose of this invention is to provide the method that a kind of extraction method prepares fiber crops chestnut shell brown pigments, with advanced extraction separation purification technique, it is simple to reach technology, extracts the yield height, product purity height, the purpose of environmentally safe.
Technical scheme of the present invention: with fiber crops chestnuts shell is raw material, through water add heat soaking, centrifugation, concentrate, ethanol lixiviate and ethanol recoverys, micro-filtration decon, spraying drying, must the brown pigments product.Concrete steps are:
1, add heat soaking: fiber crops chestnuts shell add that 8 times of deionized waters of mass ratio soak and 80-100 ℃ heated 1-2 hour;
2, centrifugation: solid substance is removed in centrifugation, obtains vat liquor, and solid substance soaks with the deionized water heating, carries out 3-4 lixiviate, merges vat liquor;
3, concentrate: the vat liquor of collection is under 50-60 ℃ of temperature, and vacuum concentration is about the 1/8-1/10 of vat liquor cumulative volume to the concentrated solution volume;
4, ethanol lixiviate: the food grade ethanol with 99% is pressed concentrated solution: ethanol volume ratio 1: 3 lixiviate 8-10 hour, and the centrifugation impurity elimination gets alcohol extract;
5, ethanol reclaims: alcohol extract carries out getting feed liquid after ethanol reclaims;
6, micro-filtration: feed liquid is carried out micro-filtration with 0.2 μ m microfiltration membrane, remove impurity and get micro-filtrate;
7, spraying drying: micro-filtrate adopts 160-180 ℃ of inlet temperature, temperature out 75-80 ℃ to carry out spraying drying, makes fiber crops chestnut shell brown pigments product.
It is the hollow fiber microfiltration membrane of 0.2 μ m that micro-filtration adopts membrane pore size.
Beneficial effect of the present invention: it is that raw material extracts fiber crops chestnut shell brown pigments product that the present invention mainly considers with fiber crops chestnut shell, and can adapt to the needs of large-scale commercial production.China's fiber crops chestnut husk as raw material is abundanter, but the research of extracting fiber crops chestnut shell brown pigments from fiber crops chestnut shell is less, the production of fiber crops chestnut shell brown pigments product is a blank in China, and the high-quality fiber crops chestnut of Development and Production shell brown pigments can satisfy food-processing and the painted needs of textile garment.
Fiber crops chestnuts shell brown pigments is a kind of natural and have the green food additive and the environmental-friendly pigment of nourishing function, can be widely used in the dyeing of food-processing industry and textile garment.The bright-coloured purity of fiber crops chestnut shell brown pigments is used in the food-processing, and stability is good, nontoxicity, and nutritious and pharmacological function; Be used in the clothes dyeing, colour fastness is strong, non-stimulated, has no side effect, and nourishing function is arranged.This product is easy to use, safe, cost performance is superior, has advantages such as natural, pure, environmental protection, health care.
