Abstract
The present invention discloses preparation process of bigflower cape jasmine fruit yellow pigment. Mature bigflower cape jasmine fruit is first treated through stoving, crushing, alcohol leaching, filtering, recovering alcohol, spray drying and re-crushing, then extracted inside a multifunctional extracting tank with alcohol solution at 46-54 deg.c, and finally spray dried in a spray drying machine to obtain bigflower cape jasmine fruit yellow pigment product with water content of 0.50-0.72. The bigflower cape jasmine fruit yellow pigment is one kind one natural food color with A238/A440 ratio not higher than 0.20, extracting rate up to 92.1 % and color number of 50.5.
Description
Technical field:
The present invention relates to a kind of extraction preparation method, particularly preparation process of water base gardenia yellow of active ingredients of plants.
Background technology:
The world market is very big to the demand of natural food colour, has good development space and vast market prospect.Water cape jasmine natural food colour is a popular new type natural food dye in the world in recent years, has that raw material is easy to get, inexpensive, Product Safety and a good stability, and advantage soluble in water, easy to use.The prepared water base gardenia yellow quality of the preparation method of China's prior art is not ideal enough, contains a large amount of impurity jasminoidins.Studies show that the water base gardenia yellow major ingredient is Crocin (maximum absorption wavelength 440 nanometers of the aqueous solution), as the absorbance (A of pigment solution in maximum absorption wavelength 238 nanometers of jasminoidin
238) with the absorbance (A of maximum absorption wavelength 440 nanometers of Crocin
440) ratio (A
238/ A
440) less than 0.20 o'clock, can avoid the generation of green realization elephant.The specification of quality of world market is (A at present
238/ A
440) ratio is smaller or equal to 0.20.So the water base gardenia yellow that China produces is difficult to take part in international competition.
Summary of the invention:
The objective of the invention is to eliminate above-mentioned the deficiencies in the prior art, a kind of pigment purity height is provided, have and save time, economize solvent, simple to operate, extraction yield and the high preparation process of water base gardenia yellow of look valency.
The present invention is achieved by following technical proposals: real selected sophisticated water cape jasmine fresh fruit, remove impurity, oven dry is handled, broken, the ethanol lixiviate, filter, reclaim ethanol, spraying drying, the water ratio of the cape jasmine fruit after its oven dry is handled is not more than 10%, be crushed to until the sheet fruit sheet that is 3～5 millimeters, put into multi-function extractor by 300 kilograms sheet fruit sheet then at every turn, adding content is 60% ethanol, temperature is 46-54 ℃ in jar, time is lixiviate in 110-130 minute, carry out ethanol after filtering through 120 order whizzers again and reclaim that to reach solid-liquid ratio density be 1.10-1.14, in drying machine with centrifugal spray, carry out spraying drying then; Spray-dired intake air temperature is 175-195 ℃, and the air outlet temperature is 85-105 ℃, and the time is 230-250 minute, and the water ratio that makes the finished product water base gardenia yellow is 0.50-0.72.
Described recovery ethanol is gel chromatography reconcentration method: static state deposition is removed seston and throw out after 24 hours in storage tank, be preferably 48-50 ℃ at multi-functional concentrated built-in temperature then, time is 330-390 minute concentrated and recovery ethanol, and reaching solid-liquid ratio density is 1.11-1.13.
Described recovery ethanol is to surpass to cross method for refining: the time is 220-260 minute in surpassing filter, reclaims ethanol by centrifugal ultra-filtration, and reaching solid-liquid ratio density is 1.11-1.13.
The jar temperature that described sheet fruit sheet is put into multi-function extractor is preferably 48-52 ℃, and the time is preferably lixiviate in 115-125 minute.
Described spray-dired intake air temperature is preferably 180-190 ℃, and the air outlet temperature is preferably 90-100 ℃, and the time is preferably 235-245 minute.
Beneficial effect of the present invention is: adopt the resulting its (A of water base gardenia yellow natural food colour of preparation process of water base gardenia yellow of the present invention
238/ A
440) ratio is smaller or equal to 0.20, the extraction rate reached to 92.1% of pigment, the look valency is 50.5, corresponding Gardenia Yellow yield is 12.5%.Realized pigment purity height, and had and save time, economize solvent, simple to operate, extraction yield and the high advantage of look valency.
