Abstract
The invention relates to a method for extracting radish haematochrome from a carrot. The method is characterized by comprising the following steps: (1) pre-treatment of raw materials; (2) extraction; (3) filtering adsorption; (4) filtering concentration; (5) alcohol precipitation concentration; (6) adjustment of a liquid finished product; and (7) preparation of a powder finished product. The method is short in extraction time and improved in extraction rate of radish haematochrome; product lose is reduced by using the method to extract the radish haematochrome; and the product is high in purity and good in quality.
Description
Technical field
The invention belongs to technical field of pigment extraction, be specifically related to a kind of method extracting radish red pigment from Radix Dauci Sativae.
Background technology
That is familiar with synthetic colour along with the mankind gos deep into, and the demand of natural pigment will increase day by day.Radish red pigment belongs to natural edible pigment, and it is bright in luster, and radish red pigment is because of good heat resistance, and stability is high, and has certain antioxygenation and pharmacological property.Can the field such as widespread use food, medicine, health care, weaving, develop this product wide market, development potentiality is huge.
Natural pigment has safety non-toxic, beautiful in colour, very popular, and bring huge economic benefit to painted, the foreign exchange earning of edible product especially, national governments and entrepreneur extremely pay close attention to.But, at present in radish red pigment extraction and purification techniques, traditional technology many employings soak extraction method, extraction time is long, and the extraction yield of radish red pigment is very low; Concentrate with the thickening equipment of routine, the loss of product is large, causes that product purity is low, poor quality, production cost are very high.
Summary of the invention
The object of the invention is to solve the technical problem that the product purity existed in existing technique is low, poor quality, production cost are very high, provide a kind of method extracting radish red pigment from Radix Dauci Sativae, it is characterized in that, said method comprising the steps of:
(1) raw materials pretreatment: select color dark, freeze without wound, without rotting, without the impurity such as turnip with red inside cleaning removal silt of disease and pest, wash with the ozone of 5-8%, stripping and slicing;
(2) extract: aqueous citric acid solution turnip with red inside being put into pH=3.0-3.5, lixiviate 2-3h at 45-55 DEG C, uses whizzer extracting chlorophyll;
(3) Filtration Adsorption: by extraction liquid filtration under diminished pressure while hot, by macroporous resin adsorption post on the radish red pigment liquid of clarification, adsorbs;
(4) filtering and concentrating: by aforesaid liquid filtration under diminished pressure, control temperature is 60 DEG C of-65 DEG C of concentrating under reduced pressure;
(5) alcohol precipitation concentrates: by the solid-liquid ratio of 5-10g/ml, raw material being dipped in volumetric concentration is in the alcohol solvent of 70%-85%, and then control temperature is 60 DEG C of-65 DEG C of concentrating under reduced pressure;
(6) liquid end product is modulated: being eluted to water lotion turbidity with the alcohol of 70%-80% is 0-0.3, and pH value is 6-7, can obtain liquid end product;
(7) powder product processed: by aforesaid liquid finished product, is put in spraying machine, and inlet temperature is 160-220 DEG C, and temperature out is 80-90 DEG C, and atomization drying can obtain powder product.
A kind of above-mentioned method extracting radish red pigment from Radix Dauci Sativae, is characterized in that, in described step (2), whizzer is with the centrifugal 8-12min of 2500-3500r/min.
A kind of above-mentioned method extracting radish red pigment from Radix Dauci Sativae, is characterized in that, in described step (3), the one in AB-8, LX-68M, XDA-8 selected by macroporous resin adsorption post, adsorption column height 3-3.5m, diameter 0.8-1.0m, loaded resin 300kg, feed rate is 2-10kg/min.
A kind of above-mentioned method extracting radish red pigment from Radix Dauci Sativae, is characterized in that, vacuum tightness concentrated in described step (4) or (5) is 0.18MPa-0.1MPa.
The beneficial effect of the invention:
The invention provides a kind of method extracting radish red pigment from Radix Dauci Sativae, material source is extensive, and production cost is low.Compared with the soak extraction method that traditional technology adopts, extraction time shortens, and the extraction yield of radish red pigment improves.The radish red pigment extracted by the method reduces the loss of product, and the product purity of production is high, quality better.
