Embodiment 1

[0018] Embodiment 1: Taking the extraction of 1 ton of capsicum granules as an example, the method for improving the color yield of capsicum red pigment is described in detail.

[0019] (1) Add 10kg of soybean isoflavones (1% of the weight of pepper granules) to the extraction solvent, where the extraction solvent is a mixed solvent of 6# solvent oil and ethyl acetate, and the mixing ratio is 6# solvent oil:ethyl acetate=7 :3(weight);

[0020] (2) Send the chili granules into continuous countercurrent extraction equipment, and conduct continuous countercurrent extraction between the chili granules and the extraction solvent added with soybean isoflavones, with a solid-to-liquid weight ratio of 1:3; the continuous countercurrent extraction equipment is as follows: figure 1 As shown; pepper particles are continuously fed from the head end of the equipment, while the extraction solvent is continuously fed from the tail end of the equipment, and the pepper particles and the extrac...

Embodiment 2

[0024] Embodiment 2: Taking the extraction of 1 ton of capsicum granules as an example, the method for improving the color yield of capsicum red pigment is described in detail.

[0025] (1) Add 10kg of vitamin E (1% of the weight of pepper granules) to the extraction solvent, where the extraction solvent is a mixed solvent of 6# solvent oil and acetone, and the mixing ratio is 6# solvent oil: acetone = 5:2 (weight );

[0026] (2) Send the pepper granules into the continuous countercurrent extraction equipment, and conduct continuous countercurrent extraction between the pepper granules and the extraction solvent added with vitamin E, and the weight ratio of solid to liquid is 1:4;

[0027] (3) During the extraction process, gradient cooling extraction was adopted, and the extraction was carried out 7 times. The temperature of the extraction solvent newly entering the continuous countercurrent extraction equipment was 50°C. Control the temperature of the feed liquid to 32°C, a...

Embodiment 3

[0030] Embodiment 3: Taking the extraction of 1 ton of capsicum granules as an example, the method for improving the color yield of capsicum red pigment is described in detail.

[0031] (1) Add 10kg of tea polyphenols (1% of the weight of pepper particles) to the extraction solvent, where the extraction solvent is a mixed solvent of 6# solvent oil and ether, and the mixing ratio is 6# solvent oil: ether = 6:2 (weight );

[0032] (2) Send the pepper granules into the continuous countercurrent extraction equipment, and conduct continuous countercurrent extraction between the pepper granules and the extraction solvent added with tea polyphenols, and the weight ratio of solid to liquid is 1:5;

[0033] (3) During the extraction process, gradient cooling extraction was adopted, and the extraction was carried out 7 times. The temperature of the extraction solvent newly entering the continuous countercurrent extraction equipment was 49 °C. Control the temperature of the feed liquid ...

Abstract

The invention discloses a method for increasing the yield of a color value of capsanthin. The method comprises the following steps of: extracting hot pepper particles, concentrating, obtaining capsanthin crude extract after removing a residual solvent, and obtaining the capsanthin by removing the pungency of the capsanthin crude extract; and extracting the hot pepper particles by adopting an extracting solvent to which a natural antioxidant is added in the extraction process. According to the method, the antioxidant is added to the extracting solvent so that on the one hand, the antioxidant consumes dissolved oxygen in the solvent so as to reduce the impact of the dissolved oxygen on the capsanthin, and on the other hand, the antioxidant can be fully in contact with the hot pepper particles in the extraction process so as to fully take effect, thereby the yield of the color value of the capsanthin can be effectively increased. The method is simple in technology and convenient to operate, has the obvious effect on the increasing of the yield of the color value of capsanthin and can realize the industrial production.

Description

technical field [0001] The invention belongs to the field of food engineering, in particular to a method for improving the color value yield of capsanthin. Background technique [0002] Capsanthin is a deep red natural red pigment obtained from the peel of red pepper. As a green and environmentally friendly product, it has delicious color, no toxic and side effects, and has certain curative effect and health care function and high nutritional and physiological value. It has been approved by the US FDA and the UK. , Japan, EEC, FAO / WHO and China GB and other organizations have approved it as a class A food coloring, which is not limited in use and is widely used in food, medicine, cosmetics, beverages and children's toys. [0003] At present, the methods for extracting capsanthin mainly include oil-soluble method, solvent method, and supercritical CO2 extraction method. The oil-soluble method and the solvent method are conventional methods. In the oil-soluble method, it is d...
