Abstract

The invention discloses a gardenia yellow extracting method, and relates to the technical field of gardenia yellow preparation. The gardenia yellow extracting method comprises the following steps: selecting high-quality gardenia fruits for standby, drying and smashing the gardenia fruits, spreading the smashed gardenia fruits in a screen, spreading edible salt to be subjected to airing for 3-4 hours, then, placing the gardenia fruits into a vacuum container, adding a CaCO3 solution and an ethanol solution for extraction, filtering, enabling the filtrate to flow through a porous adsorbent resin, eluting the resin with a 25% ethanol solution, eluting the resin with a 50% ethanol solution again, collecting the eluent, performing pressure-reduced concentration to the eluent, and drying, so as to obtain the finished product, namely the gardenia yellow. According to the gardenia yellow extracting method, the extraction is implemented in a vacuum environment, so that the pollution is avoided, high purity, environment friendliness, rich and bright color, high safety and sanitation and high yield are achieved, and improvement on the quality and yield of the gardenia yellow is facilitated.

Description

A kind of Gardenia Yellow extracting method

Technical field:

The present invention relates to Gardenia Yellow preparing technical field, be specifically related to a kind of Gardenia Yellow extracting method.

Background technology:

Cape jasmine fruit is also known as stand, more peach, SHANZHIZI, branch, yellow chicken, yellow sprout, Yellow Fructus Gardeniae etc., dry fruit oblong or ellipse, surface scarlet or reddish yellow, the remaining sepal in top, the other end is slightly sharp, there is carpopodium trace, pericarp is thin and crisp, internal surface reddish yellow, glossy, inside there is most seed, bond agglomerating, seed is oblate, scarlet or reddish yellow, the tiny verruca of close tool, be immersed in the water, water can be made to dye aureus, gas is micro-, lightly seasoned micro-acid, with individual little, complete, benevolence is full, the red person of interior exogenic color is good, can be oral, Gardenia Yellow in cape jasmine fruit can be used for juice-type beverage, assembled alcoholic drinks, color make-up on cake, ice lolly, ice cream, puffed food, jelly, face cake, candy and chestnut can etc.

And there is very large technological deficiency when traditional extraction in the Gardenia Yellow in cape jasmine fruit, it is domestic at present that to be applied to industrial extracting method on a large scale also few, a lot of technical barrier is not broken through, the present invention needs the extracting method providing a kind of Gardenia Yellow, solves the problem of current technology scarcity.

Summary of the invention:

Technical problem to be solved by this invention is to provide that a kind of pollution-free, pure environmental protection color and luster is rich and gaudy, safety and sanitation, output capacity high Gardenia Yellow extracting method.

Technical problem to be solved by this invention adopts following technical scheme to realize:

A kind of Gardenia Yellow extracting method, comprises the following steps:

1) fruit of pure color is left and taken for subsequent use by the cape jasmine fruit choosing full grains, product mutually close after color selector screens;

2) the cape jasmine fruit after sorting is put in air flow dryer and dries with the hot blast of 200 DEG C, by the time after cape jasmine fruit upper strata open fire all disappears, again hot blast temperature is dropped to 60 DEG C to dry, when cape jasmine fruit bottom surface temperature can reach 60 DEG C, then sample examination moisture content, when water content reaches 10-12%, stop drying;

3) the cape jasmine fruit after drying is put in the steamer having installed radiator valve and water tester carry out steamings and fry, steam to make when frying cape jasmine really temperature control at 58-60 DEG C, humid control steams stir-fry 30 minutes under the condition of 8-10%;

4) the cape jasmine fruit after steaming being fried is put in crusher and carries out fragmentation, fragmentation terminates rear uniform spreading and carry out airing in screen cloth, then one deck edible salt is sprinkled, the usage quantity of edible salt and cape jasmine is that one kilogram of cape jasmine fruit evenly spills 200-300g edible salt, after after having spilt salt, natural wind dries in the air 3-4 hour, collected stand-by, only complete cape jasmine fruit need be smashed time broken;

5) put in vacuum vessel and add CaCO3 solution by the cape jasmine gathered fruit, cape jasmine fruit is 1:0.4 with the volume ratio of CaCO3, and then use the ethanolic soln of concentration 20% lixiviate 4h at the temperature of 75 DEG C, twice vat liquor is changed in centre, filters;

6) filtrate flow is through porousness polymeric adsorbent, and with 25% ethanolic soln drip washing resin, then collects this leacheate, concentrating under reduced pressure washing lotion with 50% ethanolic soln drip washing resin, dry finished product Gardenia Yellow;

In step 3) in the steamer with radiator valve and moisture tester that adopts be to prevent temperature and moisture inequality from causing the raw material of part by the fried and nutritious composition in raw material Central Plains, activeconstituents is destroyed, and radiator valve is installed in our employing on steamer, moisture tester, preheating is carried out to starting material, thermostatically controlled temp would not cause the raw material of part by the fried and nutritious composition in raw material Central Plains, activeconstituents is destroyed, and the output capacity of Gardenia Yellow can be improved, and the vacuum environment used carries out extracting the health that Gardenia Yellow can ensure environment to cape jasmine fruit, increase the quality of Gardenia Yellow,

The invention has the beneficial effects as follows: pollution-free, the pure environmental protection color and luster of extraction is rich and gaudy, safety and sanitation to adopt vacuum environment to carry out, and output capacity is high, be conducive to the quality and yield improving Gardenia Yellow.
