The present invention belongs to the technical field of condiment preparation, and specifically relates to an astaxanthin-containing condiment and a preparation method therefor. In this method, first a low-speed bead milling method is used to break the cell wall of the yeast, such that astaxanthin is directly emulsified in water, and the concentration of astaxanthin can reach 1043.17 mg/L, avoiding the use of emulsifiers and organic solvents; then a small amount of Angel yeast compound enzyme is added for enzymolysis, with the yield of amino nitrogen as high as 3.51% to 3.65% and the yield of solid matter as high as 47.18% to 49.22%; and finally the gelatinized porous starch solution and gelatin are sequentially added, with the encapsulation rate and drug-loading rate of the obtained astaxanthin-containing microcapsule powder being 75.62% to 88.5% and 1.55-10.42 mg/g, respectively. The microcapsule powder has bright color, and high astaxanthin stability and water solubility. The preparation method has the advantages of short time and mild conditions, which can reduce the industrial application cost of Phaffia rhodozyma.

The disclosure discloses a method for preparing functional grease through segmented solid-state fermentation of mixed fungi, and belongs to the field of edible oil processing. According to the disclosure, soybeans are used as a main fermentation substrate, for the requirements for different functional nutrition, the soybeans are matched with other oil seeds, fungus segmented solid-state fermentation is used and combined with a supercritical extraction fractionation technology, so that the purposes of improving the aftertaste of soybean oils and generating different flavors are achieved, and the nutritional value of the grease is improved. The fungus segmented solid-state fermentation of the disclosure can improve the oil yield, improve the fatty acid composition of the grease, and increase the content of main flavor substances such as pyrazines, alcohols and phenols, and the sensory functions such as flavor and color of the grease more meet the requirements of consumers for innovative products. Fermented dregs can be further processed to produce byproducts like functional polypeptides, so that sustainable green development is realized.
