The invention discloses a traditional Chinese medicine ginseng-astragalus paste and a preparation method thereof, and belongs to the technical field of traditional Chinese medicine preparation. The method comprises the steps of medicinal material extraction, sugar melting, paste collection and filling, during medicinal material extraction, medicinal material decoction pieces of codonopsis pilosula and astragalus membranaceus are extracted with water for three times, the first time and the second time are respectively 2 hours, the third time is 1 hour, decoction liquid is filtered and concentrated into clear paste with the relative density of 1.20 (20 DEG C), crystal sugar is refined with citric acid, then the clear paste and a preservative are added, stirring and mixing are performed, the mixture is concentrated into the relative density of 1.34 (20 DEG C), and filling is performed to obtain the product. According to the prepared ginseng and astragalus paste, the refining time of the rock candy is shortened, and the stability of the paste is improved.

The invention discloses a high-light-transmittance liquid sugar preparation method based on dynamic nano-film separation, and belongs to the technical field of sugar refining. According to the method, a dynamic nano-membrane separation technology is adopted, a raw sugar dissolving solution is directly subjected to decoloration and impurity removal through a multi-stage membrane filtration system, and liquid sugar with the light transmittance larger than or equal to 95% is prepared through a one-step method. Compared with a traditional activated carbon decolorization process, the process is shortened by 80%, and no chemical additive is left. A membrane assembly self-cleaning system and a flow dynamic adjusting technology are integrated, membrane pollution can be effectively avoided, and the separation efficiency is remarkably improved. The prepared liquid sugar is high in purity, stable in quality, green and environment-friendly in process, low in energy consumption, suitable for large-scale industrial production and wide in application prospect.

This invention discloses a method for fermenting and culturing *Yarrowia lipolytica* for feed using waste liquor from corn processing for sugar refining. The invention uses glucose crystallization secondary mother liquor and corn steep liquor, the main waste products from corn processing for sugar refining, as the carbon and nitrogen sources, respectively. *Yarrowia lipolytica* is cultured in a fermenter using an aerobic fed-batch method. The required culture medium and feed solution, apart from necessary pH adjustment and the addition of an antifoaming agent, only require the secondary mother liquor and corn steep liquor. With the culture medium and fermentation operations remaining the same in the early stages of fermentation, the only change in the later feeding stage is the ratio of the secondary mother liquor and corn steep liquor in the feed solution. This achieves the goals of high lipid accumulation, high protein accumulation, and increased cell yield in the cultured *Yarrowia lipolytica* cells, without altering the characteristics of the accumulated lipids being high in polyunsaturated fatty acids and the proteins being rich in essential amino acids such as lysine, serine, and leucine.
