Abstract
The present invention provides a method for extracting natural edible haematochromes from red core radishes. In the method, red core radishes are soaked, pressed, filtered and then processed by pectic acid, and a haematochrome liquid is collected after the adsorption of upper columns, water washing and elution; natural edible haematochromes can be extracted through vacuum concentration and spray drying. The haematochromes have the advantages of high color value, high water solubility and no obvious radish smell.
Description
The present invention relates to a kind of extracting method of natural food colour.
Along with socioeconomic fast development, the application of pigment more and more widely, it is widely used in, and fruit-flavored beverage, candy, cake, assembled alcoholic drinks, cold food, jelly, medicine coat are painted, preserved fruit, bowel lavage, the first-class all many-sides of filling.The pigment of Shi Yonging has synthetic colour and natural pigment two big classes in the market.The derivative of synthetic colour polyphyly coal tar does not only have nutritive value, and harmful, and therefore many synthetic colours have been under an embargo and have been used in food.China allows to use synthetic colours such as carmine, lemon yellow, fixed indigo plant, amaranth at present, but addition has been subjected to strict restriction.Natural food colour is by extracting in the natural phant, and is harmless, and along with the raising of people's quality of life, natural food colour will progressively replace synthetic colour.At present the natural pigment kind has beet red, Kaoliang red, capsanthin and monascorubin etc., and every kind of pigment is owing to extract from different plant materials, and its extracting method has nothing in common with each other.As " method of extracting Chinese sorghum red pigment by use of water " of on March 15th, 1991 application (application number: 91101637.6, publication number: patent application CN1065079A) discloses a kind of extracting method of red sorghum pigment." manufacture method of high colour-value water-soluble red pigment of red rice " of on September 13rd, 94 application (application number: 94115547.1, publication number: patent application CN1123327A) discloses a kind of manufacture method of monascorubin.
Chongqing City's Fuling District is produced a kind of radish of uniqueness--turnip with red inside (having another name called rouge radish), this radish is scarlet by epidermis to heart entirely, pigment content is high, because it is in Fuling Prefecture's growth, so the extraction of its pigment is not also had a cover efficient ways so far.
The purpose of this invention is to provide a kind of turnip with red inside of producing with Chongqing City's Fuling District uniqueness and make raw material, extract the method for natural edible radish red pigment,, satisfy the demand of people natural food colour to produce the water-soluble turnip with red inside haematochrome of high luminance relay valency.
Method of the present invention is after the turnip with red inside that Chongqing City's Fuling District uniqueness is produced is cleaned chopping, do to add the polygalacturonase stir process after digestion agent lixiviate, the press filtration with acidic aqueous solution, its mixeding liquid temperature is 30-60 ℃, after essence filter, upper prop absorption, washing, eluent with acid solution, the preparation of second alcohol and water carries out wash-out, effusive haematochrome liquid is collected, made finished product turnip with red inside haematochrome through vacuum concentration, spraying drying.The filter residue that obtains after lixiviate, press filtration can carry out the lixiviate second time, press filtration.
The pigment that extracts with method of the present invention is a water-soluble red colouring matter, its good water solubility, no obvious radish flavor under normal working concentration, the look valency can be 45,55 and 65 above three class, be higher than the standard of the look valency 4 of the GB GB6718-86 of People's Republic of China (PRC) regulation far away, satisfied the demand of people well high luminance relay valency natural food colour.Turnip with red inside is widely planted in the Fuling Prefecture, and its unique purposes is exactly that Fuling resident is using throughout the year and cooks pickles at present, does not obtain effective development and utilization.So the present invention will open up a new processing approach to turnip with red inside, greatly improve the added value of turnip with red inside.
Now the present invention is described in further detail with following embodiment.
To produce the look valency is that 65 turnip with red inside haematochrome 0.5kg is an example: the radish silk that is cut into diameter 2-3mm after the 50kg turnip with red inside is cleaned, make digestion agent with the aqueous hydrochloric acid that 150kg water and 75ml HCl form, with radish silk and combined lixiviate, the lixiviate material is packed in the filter cloth bag, place and squeeze out filtrate in the expeller, filter residue after the squeezing is used the same method and carries out the lixiviate second time again, press filtration, get filtrate 165L, filtrate after the secondary lixiviate press filtration is added 8.25g polygalacturonase stir process, mixeding liquid temperature is 30-60 ℃, adding accurate filter cloth with plate filter filters, get clear filtrate 165L, with the absorption of filtrate upper prop, resin volume 30L, with the distilled water flushing resin with further removal of contamination, until flowing out clear liquor.With hydrochloric acid, 95% second alcohol and water eluent 30L drip washing resin in ratio (by volume) preparation of 0.03-0.07: 55-65: 35-45, begin when waiting to flow out red pigments liquid to collect, to look light till, must make with extra care pigment solution, it is 65 red core radish haematochrome dry powder that pigment solution is made 0.5kg look valency through vacuum concentration, spraying drying.
Claims (2)
1, a kind of turnip with red inside that utilizes Chongqing City's Fuling District uniqueness to produce extracts the method for natural edible radish red pigment, it is characterized in that after the raw material turnip with red inside cleaning chopping, do to add the polygalacturonase stir process after digestion agent lixiviate, the press filtration with acidic aqueous solution, 30-60 ℃ of its mixeding liquid temperature, after essence filter, upper prop absorption, washing, eluent with acid solution, the preparation of second alcohol and water carries out wash-out, collects haematochrome liquid, and haematochrome liquid is formed through vacuum concentration, spraying drying.
2, by the described method of claim 1, the filter residue after its lixiviate, the press filtration can carry out the lixiviate second time, press filtration.
