This invention belongs to the field of biotechnology, specifically relating to a recombinant Saccharomyces cerevisiae strain and its application in the production of safflowerin compounds and their derivatives, such as safflowerin, isocrocetin, or hydroxysafflower yellow A. 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.
