Abstract

The invention relates to an extraction method of natural pigments, in particular to an extraction method of a capsaicin ointment. The extraction method comprises the following steps of: putting particles made by mildew-free dried chili powder into an extraction container; carrying out extraction on raw particle materials by taking dimethyl ether as a solvent, carrying out solid-liquid separation after extraction, and carrying out repeated extraction 2 to 8 times on separated solid phase; and carrying out filtration or settlement on liquid phase, removing tiny impurities in the liquid phase, decompressing and separating into gas phase and concentrate, controlling the temperature of the concentrate to 20 to 50 DEG C, removing water and volatile matters under the condition that the gauge pressure is less than -0.085Mpa, and preparing the capsaicin ointment. The capsaicin ointment extracted by using the method is not limited by species of raw materials and capable of fully utilizing raw material resources, has high extraction ratio, low slag residual, light color of chili meal, low production cost and remarkable market competition advantage, and is not only suitable for chili with low piquancy degree, but also suitable for chili with high piquancy degree.

Description

The method of extracting capsaicin ointment from dimethyl ether

Technical field

The present invention relates to a kind of extraction method of natural pigments, relate in particular to the extracting method of capsanthin ointment.

Background technology

Red pepper is a kind of common agricultural-food, wherein contains capsicine (pungent element), natural red colouring matter etc.Low pungent element is as seasonings, and height pungent element has analgesia, anti-inflammatory, germicidal action; Capsanthin is natural haematochrome, can be used for medicine or superior cosmetics industry, and is without any side effects.At present, the method for extraction capsanthin ointment mainly contains from red pepper: normal hexane extraction method (CN1082570A); Alcohol solvent extraction method (CN1053803A) etc., owing to select the difference of raw material of hot pepper or use solvent for use, mix ingredients and the quantity extracted are also inequality, big capsicum dregs of rice blackening of resulting capsicum dregs of rice water content or peppery haematochrome extract not exclusively, yield is lower, and cost is higher.

Summary of the invention

The object of the present invention is to provide a kind of extracting method of capsanthin ointment, as the solvent extraction capsicum, improve capsanthin ointment yield, make the residual reduction greatly of capsicum dregs of rice slag, reduce cost with dme.

The method of extracting capsaicin ointment from dimethyl ether may further comprise the steps:

(1) preparation capsicum particulate material: cause after the chilli that nothing is gone mouldy is ground into 20～60 purpose powder Particulate material, put in the extraction vessel;

(2) extract: with the dme is that solvent extracts particulate material, and the weight ratio of particulate material and solvent is 1: 0.8～6, and extracting temperature is 10～45 ℃, and extraction time is 10～60min; Carry out solid-liquid separation after extracting end, isolating solid phase is repeated to extract 2～8 times by the said extracted processing condition, the solid phase after extracting is the capsicum dregs of rice;

(3) reclaim solvent: (2) isolating liquid phase is filtered or sedimentation, remove fine impurities wherein, decompression separation is gas phase and enriched material, and gas phase is compressed and liquefied the recovery solvent;

(4) product separation: (3) isolating enriched material controlled temperature at 20～50 ℃, under the condition of gauge pressure less than-0.085Mpa, is removed moisture and volatile matter content, obtain the capsanthin ointment.

Use method of the present invention to extract the capsanthin ointment, not limited by raw material variety, can make full use of raw material resources, the extraction yield height, slag is residual low, the lighter color of the capsicum dregs of rice, the capsicum that not only is fit to hang down the pungent degree, be more suitable for the capsicum of high pungent degree, production cost is low, and market competition advantage is obvious.
