Embodiment 1

[0020] A gardenia fruit extraction process, comprising the following steps:

[0021] (1) Raw materials: weighed by mass parts: gardenia fruit 43-46, rosemary 25-28, green tea 0.5-0.8;

[0022] (2) Beating:

[0023] a. After the gardenia fruit is crushed, it is added to the reaction tank at a ratio of 3-5:1. The temperature of the reaction tank is 60-65°C. After heating and stirring for 5 minutes, add rosemary to the reaction tank, continue to stir for 10mim, and then let it stand for precipitation , discharge excess upper liquid to obtain clean slurry;

[0024] B, green tea is joined in another reaction tank by the ratio of 5-8:1, and reaction tank temperature is 65-70 ℃, heats and stirs 30min, obtains green tea solution;

[0025] c. Add the mixed solution in a and the green tea mixed solution in b into the reactor according to the ratio of 1-3:10, and stir evenly for 5 minutes to obtain starch slurry;

[0026] (3) High-pressure homogenization: add polyacrylamide in molten ...

Abstract

The invention relates to the technical field of plant extraction process and particularly relates to an extraction process of gardenia fruits. The extraction process comprises the following steps: preparation of raw materials (natural plants, fruits and vegetables), pulping, high-temperature homogenization, horizontal spiral separation, disc separation, concentration of a first-level membrane, concentration of a second-level membrane, separation of a ceramic membrane, low-temperature concentration, spray drying and acquisition of a finished product. Compared with the prior art, the extractionprocess has the beneficial effects that pure nature of an original material is preserved, the novel technique is environment-friendly, a clean energy source is used in the whole process, the contentsof heavy metals and pesticide residues in a product of the extraction process are lower than detection limit values, and the product is relatively high in purity.

Description

technical field [0001] The invention relates to the technical field of plant extraction technology, in particular to a gardenia fruit extraction technology. Background technique [0002] At present, most manufacturers adopt the ethanol extraction method. The process includes: crushing the ripe gardenia fruit and adding CaCO3. Extract with 20% ethanol solution at a temperature of 75°C for 4 hours, change the extraction solution twice in the middle, filter, and the filtrate flows through the porous adsorption resin, rinse the resin with 25% ethanol solution, and then rinse with 50% ethanol solution Resin and collect the eluent, concentrate the lotion under reduced pressure, dry to obtain the finished pigment, or vacuum thin film evaporation concentration, spray drying, the process is relatively complicated and the purity is not high. Contents of the invention [0003] In order to solve the technical problems existing in the above-mentioned prior art, the present invention p...
