Abstract
The present invention provides one kind of natural edible red pigment extracted from plant material and its preparation process and use. Strictleaf dragon dracaena as material is processed through cold soaking, press filtering, concentration, drying, etc. to prepare the natural edible red pigment. The prepared red pigment has no toxicity, no corrosion, bright color and long preserving period, is stable to light, heat, acid, alkali and reductant, and may be used as coloring agent for food, beverage, medicine and cosmetics.
Description
Technical field
The present invention relates to a kind of natural phant food dye, particularly use natural food colour of plant extract and its production and use.
Background technology
Food dye (promptly edible tinting material) is the important additives of decorateeing food in modern food industry.At the look of modern food, perfume (or spice), hide, in the vision of shape, the sense of taste, sense of smell lot of essential factors, look ranks first, the importance of the color harmony color and luster of visible food.The human consumer always craves in food, beverage, the makeup etc. safe, natural, pleasant color harmony color and luster.Food dye be able to be given this stimulation of people, causes appetite of people, gives the fine enjoyment of people.Therefore, food dye was just adopted by the mankind before more than 4,000 years, and is indispensable in processing such as food, beverage, makeup so far, and show more physiological function day by day.
Quite a few is to choose from mineral for the food dye that the past people adopt, but most of mineral pigment is harmful heavy metal element, thereby does not re-use at present.Once used synthetic colour later in a large number, but carcinogenic, teratogenecity effect that the combination colour that has have, so the pigment of selecting for use at present has been edible natural pigment substantially, they mainly are meant from plant, microorganism, animal material, with physical method extraction, purifying and the natural coloring material that obtains.These plants, microorganism, animal material all are nontoxic generally.Therefore, the security of natural pigment is higher.For example from the capsanthin natural pigment of capsicum preparation, by the Red kojic rice of monascus strain fermentative preparation, the female polypide of fat worm for oral administration is extracted the cochineal of purifying etc.Though the natural pigment majority is the edible portion that derives from natural phant, microorganism, animal, what have also has some physiologically actives, as gardenia yellow, carotene, Testa arachidis hypogaeae is red, Asian puccoon is red, turmeric, theine etc., safety non-toxic not only, can also be used for the treatment of some disease, be traditional Chinese medicine.
The following stated of the present invention also be a kind of traditional Chinese medicine, its name is called Dracaena cochinchinensis, Dracaena cochinchinensis is Liliaceae Dracaena cochinchinensis Dracaena cochinchinensis (Lour.) S.C.Chen, Dracaena cochinchinensis is the perennial evergreen shrub, high 2-5 rice, blood red, the surperficial incarnadine of fibrous root of the root endo-endothelial layer band that epiblem is smooth, thicker, stem is upright, and branch is often arranged, bark beige, the close ring-type leaf scar of tool, more obvious with sprout.Contain the fat xylem and concentrate the red-brown resin that forms through organic solvent extraction, all the time, people use it as a kind of medicine, are one of traditional categories of Chinese medicine.
Summary of the invention
The inventor is in the research process to Dracaena cochinchinensis, the red pigments of having found Dracaena cochinchinensis extract again has stable, the tint permanence that present many red pigments do not possess and reaches character such as safety well, so carried out many research and trial, and, do not find the extract of Dracaena cochinchinensis is reported as the open source literature of natural food colour through domestic and international Indexing of Scien. and Tech. Literature.
The method that the present invention utilizes Dracaena cochinchinensis to prepare natural pigment comprises pulverizing, solution lixiviate, filtration, concentrated, the drying and other steps of raw material.Concrete steps are as follows:
1. raw material: choose Dracaena cochinchinensis and contain fat xylem or bark or trunk.
2. pulverize: remove impurity,, be ground into meal the raw material section.
3. soak: by the Dracaena cochinchinensis meal: the ratio of organic solvent=1: 3～1: 6 (mass ratio) was thrown in lixiviate is irritated dipping 1-3 hour, filtration (or extrusion filtrate).Repeat dip operation once with identical solvent.
4. reclaim, concentrate: twice filtering filtrate merging reclaimed solvent, and being condensed into relative density is the thick paste of 1.28～1.33 (60 ℃).
5. dry: thick paste send 50-85 ℃ vacuum drying oven drying, grinds again, obtains product, packs and can preserve 3-5.
Above-described organic solvent is ethanol or vinyl acetic monomer, sherwood oil, acetone, perhaps other lower alcohol, and as propyl alcohol, butanols etc., when using pure time-like, its volumetric concentration (V/V) is 50%～95%.
The preparation-obtained pigment character of the present invention is as follows:
1. solvability
Take by weighing 9 parts of 0.0100g pigments, add the different solvents of 20.00ml respectively, place 24h, find that this pigment is dissolved in alcohol, diluted alkaline, acetone, ethyl acetate, and present redness in various degree, be slightly soluble in ether, water insoluble and sour.
2. to the stability of soda acid
Take by weighing the 0.0237g pigment, be made into 0.03% solution, regulate its pH value from 1～14, observe its colour-change, it is less to find that pigment is influenced by potential of hydrogen, and it can usually use as redness between pH=5～12, can be used as orange-yellow use usually between pH=1～4.
3. to the stability of light
Get 4 part of 0.03% pigment solution and place colorimetric cylinder, 2 parts place refrigerator (2～6 ℃), and 2 parts place indoor light place, and every 7d surveys an absorbancy (at λ
MaxFind that solution is subjected to the influence of light bigger down).But dry product is not subjected to the influence of light substantially, and its quality guaranteed period reaches 5 years.
4. to the stability of heat
Get 4 parts of 0.03% pigment solutions, place 60～70 ℃ heat 30,60,90 respectively, 120min, at λ
MaxUnder survey its absorbancy, find that its thermotolerance is very good, and along with the growth of heat-up time, its color is deepened gradually.
5. to the stability of oxygenant
Prepare 1%, 2%, 3%, 4%, 5% H respectively
2O
2Pigment solution, survey it at λ at different time
