Embodiment 1
[0038] The raw material used is three cherry peppers, and the red pigment per kilogram of raw material contains 11.3 color values and 284 spicy degrees of chili.
[0039] Peppers are screened, peeled, and crushed into 60-mesh powder, and granules with a particle size of 3mm are made into granules by a granulator. The granules are sent to the extraction device at a temperature of 70°C, and are extracted with a mixed solvent of n-hexane and ethyl acetate for 2 hours. , the weight ratio of n-hexane and ethyl acetate is n-hexane: ethyl acetate=4:1; mixed solvent: the weight ratio of material is 15:1.
[0040] The obtained extract enters the concentrator to be concentrated under the condition of temperature 60°C and negative pressure of 0.09Mpa. The concentrated solution is separated from the pigment and capsicum essence by using a thin film evaporator, and the crude capsicum essence and the crude red pigment are separated; The vegetarian deodorizing pot is despiced and centrifug...
Embodiment 2
[0045] 1), Airflow removal of impurities, peeling, drying, and separation of seed skins: the dried peppers are removed by airflow, and sent to the pepper peeling machine to break the skins. After the peels are broken, they are sent to the air dryer for drying.
[0046] The material enters the seed skin separator to separate the seed skins to obtain pepper skins and pepper seeds;
[0047] 2) Granulation: Pepper skins are coarsely crushed to 20 mesh, sent to a mill for fine crushing to 60 mesh,
[0048] The granulation machine is sent to make granules with a particle size of 4mm;
[0049] 3) Solvent extraction: send the particles into the extraction device at a temperature of 75°C, and use a mixed solvent of n-hexane and ethyl acetate for countercurrent extraction for 3 hours. The weight ratio of n-hexane and ethyl acetate is n-hexane:ethyl acetate=2 :1; mixed solvent: the weight ratio of material is 10:1.
[0050]The obtained extract enters the concentrator to concentrate und...
Embodiment 3
[0056] 1) Airflow removal of impurities, skin breaking, drying, and separation of seed skins: the dried peppers are removed by air flow, and sent to the pepper breaking machine to break the skins. After the skins are broken, they are sent to the air dryer for drying, and the dried materials enter the seed skins The separator separates the seed skins to obtain chili skins and chili seeds;
[0057] 2) Granulation: Pepper skins are coarsely crushed to 20 mesh, sent to a mill for fine crushing to 60 mesh, and sent to a granulator to make particles with a particle size of 3mm;
[0058] 3) Solvent extraction: send the particles into the extraction device at a temperature of 75°C, and use a mixed solvent of n-hexane and ethyl acetate for countercurrent extraction for 2.5 hours. The weight ratio of n-hexane and ethyl acetate is n-hexane:ethyl acetate=6 :1; mixed solvent: the weight ratio of material is 20:1,
[0059] The obtained extract enters the concentrator to concentrate under t...
