Problems solved by technology

Low-purity solvents are widely used due to their wide distillation range and low price, but it is difficult to remove residual solvents in the later stage, and the loss of color value is high, and product safety is low; while high-purity solvents improve product safety and reduce residual solvent removal. loss, but still restricts the extraction rate of the product

Embodiment 1

[0014] First, the red pepper is dried, crushed and made into the raw material of pepper particles. Weigh 30g of the pepper particles into a 500mL round-bottom flask, add an organic solvent; the organic solvent is made by adding methylcyclopentane to the No. 6 solvent, preferably 90mL of the No. 6 solvent, and then the No. 6 solvent Add 4.5mL of methylcyclopentane, that is, the amount of methylcyclopentane added by volume ratio is 5% of the amount of solvent used in No. 6, and it will form after shaking gently; after adding the above organic solvent, the temperature is Extract for 20min at 52℃. After the extraction solution is settled and filtered, the filter residue is mixed with the organic solvent, and the above extraction step is repeated twice. Second, collect the filtrate after the above three extractions, and evaporate the solvent once at a pressure of -0.055MPa and a temperature of 52°C; then perform a second evaporation at a pressure of -0.085Mpa and a temperature of 5...

Embodiment 2

[0016] Dry the red pepper, pulverize it and make it into the raw material of pepper particles, put the material of pepper particles into continuous extraction equipment, spray organic solvent, and extract at a temperature of 53℃. The above organic solvent is in No. 6 solvent It is made by adding methylcyclopentane, and the amount of methylcyclopentane added is 8% of the solvent usage amount of No. 6 based on the volume ratio. After the extraction solution is settled and filtered, the solvent is evaporated once at a pressure of -0.06MPa and a temperature of 55°C, and then the solvent is evaporated a second time at a pressure of -0.09Mpa and a temperature of 53°C to obtain primary pepper Oleoresin. The primary chili oleoresin was removed under the conditions of pressure of -0.098MPa and temperature of 52℃ to remove the residue, and then under the condition of temperature of 36℃, the spicy liquid was used to remove the spicy liquid. Solvent and sodium chloride are used as a mixed...

Abstract

The invention discloses a method for increasing the pepper red pigment yield, which comprises the following steps: extracting the pepper particle raw materials with organic solvents, and carrying out sedimentation-filtration and solvent evaporation to obtain primary pepper oil resin. The method is characterized in that the organic solvents are prepared by adding methylcyclopentane into a 6# solvent, and based on a volume ratio, the methylcyclopentane addition volume is 5-10% of the 6# solvent dosage. The invention uses the 6# solvent as extracting agents, and the moderate methylcyclopentane is added to enhance the extraction property of the hexane to the pepper red pigment in the 6# solvent, to increase the yield of the pepper red pigment product, such as increasing the pepper red pigmentyield to more than 98.2%. Moreover, the addition volume of the above methylcyclopentane has little influence on the production cost of the pepper red pigment product.

Description

Technical field [0001] The invention relates to a preparation method of capsanthin, in particular to a preparation method of capsanthin which can further improve the yield. Background technique [0002] Capsicum red pigment is a natural pigment extracted from solanaceous red pepper. Because of its bright color, good thermal stability, safety and reliability, and pharmacological effects, it is not only an ideal natural food coloring agent, but also widely used in the pharmaceutical industry, such as the coloring of tablet sugar coatings. Chili oleoresin is a crude product of red chili leached with organic solvents for the first time, and usually contains more spicy substances. However, the refined paprika is usually made of pigments, which will not give the product a pungent spicy taste. [0003] Capsicum oleoresin extraction methods include oil-soluble method, organic solvent method and supercritical extraction method. Among them, the pigments of products produced by the oil sol...
