Problems solved by technology

However, compared with capsicum oleoresin, the viscosity of oleoresin in lutein is very high, and the pigment component is crystallized, and the method proposed above cannot completely remove impurities such as odor components and oils from the oleoresin.
Moreover, the prepared pigment has peculiar smell, peculiar smell, and poor stability. If it is used as a colorant for food, cosmetics, etc., it will have adverse effects on its flavor, etc., and there are many restrictions on its use.

Embodiment example 1

[0025] Add 0.4kg of lutein (color value 393) and 0.8kg of medium-chain saturated fatty acid triglycerides into a 5-liter extraction tank, mix and stir to dissolve at 40°C, and pass in supercritical CO 2 (Extraction tank: pressure 200kg / cm 2 , temperature 40°C, CO 2 Supply rate 4kg / h), extract for 5 hours. Normal pressure was restored, and the residual lutein was taken out to obtain 0.3 kg of deodorized lutein. The obtained lutein had almost no odor peculiar to the perennial chrysanthemum, and its color value was 487 (93% of pigment recovery rate).

[0026] Example 2: Add 0.5kg of lycopene (color value 160) and 0.5kg of medium-chain saturated fatty acid triglycerides into a 5-liter extraction tank, mix and stir to dissolve at 40°C, and pass into a supercritical state CO 2 (Extraction tank: pressure 200kg / cm 2 , temperature 40°C, CO 2 Supply rate 4kg / h) in the presence of 95% ethanol, extract for 5 hours. Return to normal pressure, take out the residual lycopene, and remove ethanol with a rotary evaporator to obtain 0.3 kg of deodorized lycopene. The obtained lycopene had almost no tomato-specific odor, and its color value was 230 (86% pigment recovery rate).

[0027] Comparative case 1: Add 1 kg of lutein (color value 404) into a 5-liter extraction tank, and supply supercritical CO 2 (Extraction tank: pressure 200kg / cm 2 , temperature 40°C, CO 2 Supply rate 4kg / h), extract for 5 hours. Return to normal pressure to obtain 0.8kg deodorized lutein (color value 440, pigment recovery rate 87%). The obtained lutein has a...

comparative example 2

[0028] Comparative Case 2: Change the extraction time in Comparative Case 1 to 30 minutes, and keep other conditions unchanged. Prepare 0.7kg of lutein (color value 490, pigment recovery rate 85%). Compared with the obtained lutein in Comparative Example 1, although the odor was weakened, the odor could still be sensed.

Abstract

The invention discloses a phytochrome deodorizing and refining method. The phytochrome deodorizing and refining method includes the following steps of firstly mixing phytochrome or phytochrome oleoresin with 50-500% by mass of medium-chain saturated fatty acid triglyceride with respect to the oleoresin in an extraction tank, sufficiently stirring, and supercritically extracting CO2 (carbon dioxide) for 1-50 hours at the temperature of 20-60 DEG C and in the atmospheric pressure of 80-400kg / cm<2>; and finally restoring the ordinary pressure and obtaining the deodorized phytochrome. By the phytochrome deodorizing and refining method, impurities peculiar in smell and odor in high-viscosity oleoresin such as lutein can be separated, and phytochrome without peculiar odor and oil-group impurities can be produced.

Description

technical field [0001] The present invention relates to the field of the production method of pigment deodorization, more specifically, relates to the deodorization and refining method of vegetable pigment. Background technique [0002] Compared with the extraction method of organic solvent, the extraction method of supercritical extraction can be carried out at low temperature, the temperature or pressure hardly changes after extraction, and has many advantages such as separation of extraction components and reduction of energy costs. In recent years, this method has been widely used in the extraction, concentration, refining and deodorization of thermally unstable natural pigments. For example: US Patent No. 4,400,398 mentions a method for separating aromatic substances and pigments from green pepper or red pepper oleoresin in a supercritical state through two stages. [0003] Concentration method of natural pigments in Japan: using high-pressure CO 2 Oil-soluble capsant...
