Abstract
The present invention is process of extracting natural botanic water soluble red pigment. The process includes the following steps: crushing the plant material, soaking in acid solution, filtering in a sheet frame filter and adsorbing the filtrate with macroporous resin; eluting with ethanol, decompression concentrating while recovering ethanol, filtering the concentrate with diatomite to further eliminate impurity, and centrifuging to eliminate precipitate to obtain liquid red pigment. Or, the liquid red pigment may be further spray dried at low temperature to obtain red pigment powder. Compared with other processes of extracting red pigment, the process of the present invention is simple, safe, pollutionless, high in yield and low in cost, and may be used in large scale production.
Description
Affiliated technical field
The invention belongs to the extracting method of haematochrome, be specifically related to from No. 1, livid purple potato, purple cabbage, purple corn and beet etc. contain the method for extracting haematochrome in the natural phant of water-soluble red colouring matter.
Background technology
Food dye is important additive in the food, is widely used in food such as assembled alcoholic drinks, soda pop, ice cream, fruit juice, jelly, candy, cake etc., also can be used for makeup and medicine etc.
At present, both at home and abroad, use the artificial color of chemosynthesis more,, find that there is certain hazardness in synthetic colour to HUMAN HEALTH, it is restricted day by day even disabled along with the reach of science.Along with the people advocate naturally, back to nature, safety first, nutrition are supreme, and the research and development of food dye are along the speed development.China's natural pigment plant resources is very abundant, and that has now produced has haematochrome such as radish red, beet red, capsanthin.In recent years, along with increasing of demand, successful introduction and cultivated the improved seeds that much contain pigment, as cultivate No. 1, livid purple potato successfully through the improvement of Japanese mountains and rivers Rhizoma Dioscoreae esculentae, purple cabbage, purple corn etc. has been reported kind more than 40.In order well to utilize these good kinds, a large amount of research has been done to the extracting method of food dye by various countries, and current pressing for sought the extracting method that a kind of technology is easy, cost is low, yield is high.But, use the low temperature reflux extraction method, CO2 super critical extraction, higher, the complex process of cost at present more.
Summary of the invention
The objective of the invention is provides a kind of characteristic of utilizing the raw material composition for addressing the above problem, and uses the sour water lixiviate, this method simple equipments, the nutrient content unchanged that has promptly kept pigment, guaranteed the quality of pigment again, and the yield height, be a kind of method for extracting pigment that can be used for scale operation.
The present invention is the extracting method of such a kind of natural plant water-soluble red colouring matter of realizing for achieving the above object, and raw material soaks with sour water through chopping or after pulverizing, and merges soak solution and filters through plate filter, and filtrate is through macroporous resin adsorption; Use ethanol elution behind the purifying, the pigment concentrate that decompression recycling ethanol reclaims behind the ethanol must further remove impurity through diatomite filtration again, remove the liquid red pigment that throw out can obtain desired concn through centrifugal again, or can obtain the dried powder haematochrome through low temperature spray drying.The time of raw material through soaking with sour water is no less than 7 hours.The water-soluble red colouring matter of macroporous resin adsorption need be with behind 75% ethanol elution, decompression recycling ethanol below 50 ℃.
The present invention and other extracting method relatively, technology is easy, safe and reliable, pollution-free, can keep that raw material nutrition is constant, yield is high, cost is low.Can be used for scale operation.
Embodiment
Introduce livid purple potato No. 1 with Japan, purple cabbage, purple corn, beet are raw material, clean chopping places the molten device of opening, with the sour water below the PH3.0 (citric acid) lixiviate eight hours, vat liquor injects filtrate in the adsorption column after plate filter filters, be further purified back 75% ethanol elution, collect ethanol eluate reduce pressure in 50 ℃ reclaim ethanol after again through diatomite filtration and centrifugal impurity and the throw out of removing, both E10%1cm=100 ~ 250 look valencys the liquid red pigment or 50 ℃ of following spraying dryings both the dried powder haematochrome.
Claims (3)
1. the extracting method of a natural plant water-soluble red colouring matter is characterized in that: raw material is through chopping or pulverize the back and soak with sour water, and the merging soak solution filters through plate filter, and filtrate is through macroporous resin adsorption; Use ethanol elution behind the purifying, the pigment concentrate that decompression recycling ethanol reclaims behind the ethanol must further remove impurity through diatomite filtration again, remove the liquid red pigment that throw out can obtain desired concn through centrifugal again, or can obtain the dried powder haematochrome through low temperature spray drying.
