Embodiment 1

[0030] This embodiment provides a method for preparing deodorized safflower yellow, the specific operations are:

[0031] Take 1kg of safflower raw material, add 10L of 30-35°C deionized water at a ratio of 1:10, heat and extract twice at 15-20°C, and filter the extract with a 200-mesh nylon filter to obtain 16kg of filtrate. It is 1.25, refined with 1000ml of AB-8 macroporous adsorption resin, the adsorption capacity is 14BV, the adsorption flow rate is 0.8BV / h, and the direction is up and down. Wash with 4BV pure water at a flow rate of 0.2BV / h, in the direction of up and down. Desorb with 60% ethanol again, consumption 1.5BV, flow velocity 0.4BV / h, direction goes up and down goes out, obtains refined liquid 2474.75g, the refined liquid was 7.92. Concentrate the refined solution at 40°C to 65, obtain 245.2g safflower yellow pigment paste.

[0032] Extraction and deodorization process: use ethyl acetate to deodorize the obtained safflower yellow pigment paste. The temp...

Embodiment 2

[0036] This embodiment provides a method for preparing deodorized safflower yellow, the specific operations are:

[0037] Take 1kg of safflower raw material, add 15L of 35-40°C deionized water at a ratio of 1:15, heat and extract twice at 35-40°C, and filter the extract with a 200-mesh nylon filter to obtain 22kg of filtrate. It is 0.9, refined with 1000ml of D101 macroporous adsorption resin, the adsorption capacity is 22BV, the adsorption flow rate is 1BV / h, and the direction is up and down. Wash with 5BV pure water at a flow rate of 0.5BV / h, in the direction of up and down. Then desorb with 60% ethanol, the consumption is 2BV, the flow velocity is 0.5BV / h, the direction goes up and down, and the refined solution is obtained 2118.5g. is 8.5. Concentrate the refined solution at 50°C to 50, obtain 312.55g safflower yellow pigment paste.

[0038] Extraction and deodorization process: use a mixed solvent of ethyl acetate and n-hexane (the volume ratio of n-hexane and ethy...

Embodiment 3

[0042] This embodiment provides a method for preparing deodorized safflower yellow, the specific operations are:

[0043] Take 1kg of safflower raw material, add 17L of deionized water according to the ratio of 1:17, the temperature is 40-45°C, keep warm and extract twice at 40-45°C, filter the extract with a 200-mesh nylon filter to obtain the filtrate, and obtain the filtrate 26kg, filtrate It is 0.77, and it is refined with 1000ml of LSA-10 macroporous adsorption resin; the adsorption capacity is 26BV, the adsorption flow rate is 1.2BV / h, and the direction is up and down. Wash with 6BV of pure water at a flow rate of 0.8BV / h, up and down. Then use 60% ethanol for desorption, the dosage is 2.5BV, the flow rate is 0.6BV / h, and the direction is up and down. Obtain refined liquid 2016.6g, refined liquid is 9.2. Concentrate the refined solution at 65°C to For 43, obtain 348.82g safflower yellow pigment paste.

Abstract

The invention discloses a deodorized safflower yellow pigment and a preparation method thereof. One or more of acetate and alkane is used as an extractant and mixed with a raw material containing safflower yellow pigment at 15-35°C, and after extraction Settling and separating to obtain the extract raffinate containing deodorized safflower yellow. In the method provided by the invention, the safflower raw material is extracted with an extraction solvent, and the extract is refined with a macroporous adsorption resin to obtain a safflower yellow pigment paste. This method improves the color value of the paste, removes most of the impurities, and is beneficial to the next step of deodorization treatment. The safflower yellow pigment paste is subjected to extraction and deodorization treatment with an extraction solvent, and the lower extraction residue after sedimentation and separation is subjected to nitrogen desolventization and residue treatment, and finally spray-dried to obtain deodorized safflower yellow pigment powder. The method has the advantages of simple operation, good deodorizing effect, a deodorizing rate of more than 96 percent of the obtained product, high color value, less working procedure, and is convenient for industrialized production.

Description

technical field [0001] The invention relates to the technical field of safflower yellow, in particular to deodorized safflower yellow and a preparation method thereof. Background technique [0002] Safflower (Carthamustinctorius L.) is an annual herbaceous plant of the dicotyledonous class Asteraceae, also known as: "grass safflower", "red and blue flower", etc. It has the effects of promoting blood circulation and removing blood stasis, dredging collaterals and relieving pain. class of traditional Chinese medicine. It contains flavonoids, fatty acids, pigments, phenolic acids, volatile oils and other active ingredients. Safflower yellow (SY) is a water-soluble mixture of various components, and belongs to the chalcones in water-soluble flavonoids. [0003] Safflower yellow is an edible natural pigment approved and allowed to be used in my country, and has been included in my country's national standard GB1886.61-2015. In recent years, Chinese and foreign scholars have ca...
