Disclosed are a β-lactoglobulin-vitamin conjugate comprising sugar alcohols and a preparation method thereof. The β-lactoglobulin-vitamin conjugate comprising sugar alcohols comprises β-lactoglobulin that has been subjected to glycosylation treatment with high voltage pulses, VE, sorbitol and maltitol. The glycosylation treatment with high voltage pulses involves treating a 1 mg/mL β-lactoglobulin solution prepared with a 0.01 mol/L, Ph 7.4 phosphate buffer solution in a high voltage electric field for 80 μs, the field intensity of the high voltage electric field being 30 kV/cm, and the electric field waveform being a unipolar square wave. Modification of β-lactoglobulin by the glycosylation treatment with high voltage pulses alters the secondary and tertiary structures of β-lactoglobulin, thus effectively reducing protein sensitization. Further, addition of the sugar alcohols as a natural emulsifier enhances the rate of conjugation of the β-lactoglobulin-vitamin conjugate.

METHOD FOR PRODUCING BACTERIOCIN AND PROPANOIC ACID BASED ON XYLOSE MOTHER LIQUOR RAFFINATE
A method for producing bacteriocin and propanoic acid based on a xylose mother liquor raffinate, comprising the steps of: step one, culturing a propionibacterium shermanil seed; step two, inoculating the obtained propionibacterium shermanil seed liquid into a modified SLB culture medium or a modified MRS culture medium, performing anaerobic culture on same, separating the produced propanoic acid from a fermentation system during the anaerobic culture process, and collecting same; 1.5% of glucose being replaced with 10%-40% of xylose mother liquor raffinate in the modified SLB culture medium; 20 g of glucose being replaced with 100-400 g of xylose mother liquor raffinate in the modified MRS culture medium; and step three, centrifuging a fermentation broth and collecting the supernatant liquid. The xylose mother liquor raffinate is reused and replaces the common carbon source glucose as a carbon source in microbial fermentation. Propionibacterium shermanil can be normally fermented in a culture medium in which the xylose mother liquor raffinate is used as a carbon source to produce the bacteriocin and the propanoic acid. The fermentation broth containing the bacteriocin still has a bacteriostatic effect.
Disclosed is a method for calculating the tolerance dose of a human body to sugar alcohol and functional sugar, comprising the following steps: selecting 200 g rats as experimental animal subjects, and dividing the 200 g rats into six experimental groups and one control group, wherein each group has ten numbered rats; gavaging different doses of xylitol every day to the rats in the six experimental groups, and gavaging sucrose every day to the rats in the control group; providing sufficient drinking water and ordinary feed to all the experimental rats every day; observing and counting the number of rats with diarrhea every night; continuing over 14 days; obtaining the maximum tolerance dose of the rats in the experimental groups and in the control group to xylitol according to the diarrhea in rats on the last day combined with the intestinal segment slice image of the rats in each group and the content of diamine oxidase; and then converting the maximum tolerance dose of the rats to obtain the tolerance dose of the human body to xylitol according to the drug dose conversion formula of the experimental animal and human. The method obtains an accurate tolerance range of a human body to sugar alcohol and functional sugar by means of an animal experiment.

12 BY XYLOSE MOTHER LIQUOR BASED ON ILLUMINATION REGULATION
The present invention relates to a method for removing impurities in a xylose mother liquor. A xylose mother liquor produced during xylose production is used as a raw material, and the xylose mother liquor is pretreated by using a lytic polysaccharide monooxygenase (LPMO) and a copper ethylenediamine solution, so as to greatly reduce the viscosity of the xylose mother liquor; then, the xylose mother liquor is treated by a carbonation process to adjust the pH to acidic, thereby removing colloidal impurities to purify the xylose mother liquor, and thus, the xylose mother liquor can smoothly pass through a chromatographic separation device to obtain high-purity xylose. The present invention achieves the purpose of removing impurities in a xylose mother liquor by using a glycosyl hydrolase in combination with a carbonation process, thereby reducing the production costs and improving the utilization of the xylose mother liquor, and effectively removes colloidal impurities in the xylose mother liquor, so that the xylose mother liquor smoothly passes through a chromatographic separation device to obtain high-purity xylose, thereby improving the utilization value of the xylose mother liquor.
