The invention provides a safflower pigment extraction method. The safflower pigment extraction method comprises the following steps: preparing a safflower decoction; adding whey protein into the safflower boiling liquid, and uniformly stirring; standing for layering, removing supernatant liquid, and then regulating and controlling the pH value of the mixed liquid; selective separation of carthamin yellow and haematochrome is realized through pH control; wherein yellow pigment mud is obtained under the alkaline condition, and red pigment mud is obtained under the acidic condition; the obtained yellow pigment mud and the obtained red pigment mud are subjected to vacuum drying and then ground, and the drying temperature is 30-40 DEG C. According to the safflower pigment extraction method provided by the invention, the selective separation of safflower yellow / red pigment is realized by regulating the pH value, and the limitation of single pigment extraction is broken through; and the weather resistance of the product is effectively improved through low-temperature grinding and a color fixing agent compounding and coating process. The invention further provides application of the safflower pigment.

Through fermentation cultivation of the recombinant Saccharomyces cerevisiae strain described in this invention, the biosynthesis of safflowerin, isocrocetin, and hydroxysafflower yellow A is achieved, improving the economic efficiency of the preparation process of safflowerin, isocrocetin, and hydroxysafflower yellow A, and possessing significant market potential and promotional value.

The invention provides a natural carthamin yellow-beta-cyclodextrin inclusion compound with high stability and a preparation method of the natural carthamin yellow-beta-cyclodextrin inclusion compound, and belongs to the technical field of stable modification of natural pigments. The natural carthamin yellow-beta-cyclodextrin inclusion compound comprises beta-cyclodextrin and natural carthamin yellow, wherein the molecular ratio of the beta-cyclodextrin to the natural carthamin yellow is 1: 1. The preparation method comprises the following steps: dissolving beta-cyclodextrin in water to form a beta-cyclodextrin saturated solution, adding natural carthamin yellow into the beta-cyclodextrin saturated solution, stirring for 1 hour at the temperature of 50 DEG C, and freeze-drying to obtain the natural carthamin yellow-beta-cyclodextrin. According to the natural safflower yellow-beta-cyclodextrin inclusion compound, beta-cyclodextrin serves as a subject, natural safflower yellow serves as an object, and the inclusion compound with the low pigment loss rate and the high light stability is successfully prepared by optimizing three key process parameters including the subject-object molecular ratio, the stirring temperature and the stirring time. The protection effect on the natural carthamin yellow is improved.

The invention discloses a ternary deep eutectic solvent and method for extracting carthamin yellow and haematochrome through a one-step method, and belongs to the technical field of traditional Chinese medicine extraction. The ternary deep eutectic solvent is a clear and transparent liquid prepared by mixing choline chloride, ethylene glycol and acetamide according to a molar ratio of 1: 3: 1 and heating. According to the method for extracting the carthamin yellow and the haematochrome by the one-step method, the ternary deep eutectic solvent is used as an extraction solution, and the synchronous extraction of the carthamin yellow and the haematochrome in the safflower is realized by adopting an ultrasonic extraction method. The ternary deep eutectic solvent disclosed by the invention is biodegradable, safe and environment-friendly, and pollution of a traditional organic solvent to the environment can be avoided. According to the method for extracting the safflower pigment through the ternary deep eutectic solvent one-step method, the mass transfer process can be enhanced, synchronous extraction of the safflower pigment is achieved, the resource utilization rate is increased, the extraction time is short, the extraction efficiency is high, energy consumption is low, long-time storage can be achieved, and important significance is provided for full utilization of pigment in the safflower traditional Chinese medicinal material.
