Problems solved by technology

Even if some have also adopted macroporous adsorption resins, solvent treatment, molecular distillation or two adsorption resin separations are also combined in the process, and the final capsaicin crystallization still needs flammable and explosive organic solvents (petroleum ether, ether or n-hexane) alkane) for recrystallization, the operation steps are cumbersome, and there are still potential safety hazards

Embodiment 1

[0023] Take 33Kg of 10% capsicum essence, add 350L of 1N NaOH solution, stir at a constant temperature of 75°C for 120min, cool down to below 30°C, separate the lower layer, and set aside. The upper layer is the pigment layer, which is used for separating pigments.

[0024] Take 220Kg of the treated pharmaceutical grade AB-8 or ADS-8 resin, suspend it with deionized water, pump it into a stainless steel column, rinse it with deionized water to remove air bubbles, and set aside.

[0025] Pass the phase-inverted lower layer through the resin column at a flow rate of 1.5BV / hr. for adsorption; then eluted with 350L water and 600L 20% ethanol to remove impurities, tracked by TLC, and washed with 40% ethanol at a flow rate of 0.5-1.5BV / hr. Remove capsaicin until the elution of capsaicin is basically completed, replace 90% ethanol, and elute the red pigment at the same flow rate. Regenerate the resin with 600L of ethanol.

[0026] After the elution of the pigment is completed, repla...

Embodiment 2

[0029] Take 40Kg of 10% capsicum extract, add 400L of 1.2N NaOH solution, stir at 80°C for 60min, cool down to below 30°C, separate the lower layer, and set aside. The upper layer is the pigment layer, which is used for separating pigments.

[0030] Take 300Kg of the treated pharmaceutical grade ADS-7 resin, suspend it with deionized water, pump it into a stainless steel column, and rinse it with deionized water to remove air bubbles, and set it aside.

[0031] Pass the phase-inverted lower layer through the resin column at a flow rate of 1.0BV / hr. for adsorption; then eluted with 400L water and 400L 20% ethanol to remove impurities, tracked by TLC, and washed with 60% ethanol at a flow rate of 0.5-1.5BV / hr. Remove the capsaicin until the elution of the capsaicin is basically completed, replace the 80% ethanol, elute the red pigment at the same flow rate, and regenerate the resin with 1000L of ethanol.

[0032] After the elution of the pigment is completed, replace the residu...

Embodiment 3

[0035] Take 40Kg of 10% capsicum extract, add 400L of 1.5N NaOH solution, stir at a constant temperature of 75°C for 90min, cool down to below 30°C, separate the lower layer, and set aside. The upper layer is the pigment layer, which is used for separating pigments.

[0036] Take 310Kg of the treated pharmaceutical grade NKA-9 resin, suspend it with deionized water, pump it into a stainless steel column, and rinse it with deionized water to remove air bubbles, and set it aside.

[0037] Pass the phase-inverted lower layer through the resin column at a flow rate of 1.5BV / hr. for adsorption; then elute with 1000L water to remove impurities, follow TLC, and elute capsaicin with 50% ethanol at a flow rate of 0.5-1.5BV / hr. to The elution of capsaicin is basically completed, and 80% ethanol is replaced, and the red pigment is eluted at the same flow rate, and 1000L of ethanol is used to regenerate the resin.

Abstract

The invention relates to the field of application of plant products, and discloses a technology for preparing natural capsaicin crystal. The technology solves the problems that the technology in the prior art is fussy and low in production efficiency and has potential safety hazards and the like and a large quantity of inflammable and explosive organic solvents are used. The capsaicin crystal can be obtained by using chili extract serving as a food additive as a raw material, using water or ethanol as a solvent, removing impurities with macroporous adsorption resin, purifying and crystallizing, so that the conventional process for separating the natural capsaicin crystal from the chili extract is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to a process for producing capsaicin crystals from capsicum essence. Background technique [0002] Since chili was introduced into China at the end of Ming Dynasty, it has become a favorite spicy food in people's daily life because of its unique spicy taste. With the development of science and technology, the unique effects of chili are gradually being recognized. In addition to the well-known spicy taste, it also has the functions of analgesia, anti-inflammatory, anti-itch, anti-tumor, tear-inducing, insecticidal, hair growth, and weight loss. It is now widely used. Used in food, medicine, military, agriculture, daily chemical and other fields. [0003] The main effective ingredient of pepper is capsaicin, and the content of different varieties of peppers in my country varies greatly, mostly 0.2% to 1.0%. Capsaicin consists of more than 14 homologues. The core of the structure is as follows ( figure 1 ), they differ from each...
