This invention discloses a red yeast rice freeze-dried powder flash-release tablet and its preparation process, relating to the food processing field. It is made from the following raw materials in parts by weight: 10-30 parts red yeast rice extract, 5-20 parts fructooligosaccharides, and 0.5-5 parts gelatin. This red yeast rice freeze-dried powder flash-release tablet and its preparation process utilize a vacuum freeze-drying process, carried out entirely at low temperatures, avoiding the damage to the functional components of red yeast rice caused by traditional high-temperature drying. The proportion of open-ring monacolin K (acid form) in the resulting flash-release tablet can be stably maintained at 93%-97%, far exceeding that of traditional drying processes (usually not exceeding 30%). Simultaneously, this flash-release tablet rapidly disintegrates within 15 seconds in the oral cavity, allowing monacolin K to be directly absorbed into the bloodstream through the oral mucosa, without the need for conversion by carboxylesterases in the liver. This results in faster onset of action, higher absorption efficiency, and reduced metabolic burden on the liver.

This utility model relates to the technical field of red yeast rice extract processing equipment, and discloses a high-efficiency concentration and separation device for red yeast rice extract, including a processing mechanism with a support mechanism at the bottom; the processing mechanism includes a base plate, a mixing tank fixedly connected to the top left side of the base plate, a rotating rod rotatably connected inside the mixing tank, a spiral stirring blade fixedly connected to the surface of the rotating rod, a motor fixedly connected to the top of the rotating rod, a heater installed inside the mixing tank, and a feed pipe fixedly connected to the top of the mixing tank. This high-efficiency concentration and separation device for red yeast rice extract, driven by the motor, enables the spiral stirring blades to form a three-dimensional circulating stirring effect within the mixing tank. This stirring method can fully disperse the raw materials, allowing the extract to have comprehensive and multi-layered contact and reaction with the raw materials, greatly increasing the chances of dissolution and precipitation of the effective components, thereby significantly improving the extraction rate of the effective components.

The application discloses a method for comprehensively analyzing pigment components in Hongqu rice and application of the method in discovery of active components against Alzheimer's disease. The method first obtains mass spectrometry data of Hongqu rice extract through LC-MS / MS analysis; then, based on common fatty ketone side chains and characteristic skeletons of Hongqu rice pigments, four characteristic neutral losses including 98.0732 Da and two characteristic fragment ions of m / z 212.11 and m / z 215.11 are established as constituent units; the constituent units are used to screen target components from total data, and a molecular network is constructed for visual clustering; finally, combined with database comparison and calculation prediction, systematic identification of pigment components is realized. By using the method, 243 pigment components are successfully identified from Hongqu rice, including 185 potential new pigments. Further activity experiments show that the identified pigments, especially red pigments, have significant concentration-dependent inhibitory effects on L-glutamic acid-induced neuron injury and LPS-induced neuroinflammation, and exhibit good potential against Alzheimer's disease. The application overcomes the defects of low efficiency and incomplete coverage of traditional methods, and provides an efficient and comprehensive analysis method for deep development and quality control of Hongqu rice.
