The invention discloses a method for preparing high-purity fructo-oligosaccharide by utilizing a molecular sieve-simulated moving bed. The method comprises the following steps: taking common fructo-oligosaccharide solution as a raw material and diluting with pure water; adding a compound adsorbent composed of activated carbon and polyaluminium sulfate into the diluted liquid fructo-oligosaccharide; stirring, filtering and taking filtrate; separating and purifying the filtrate through the simulated moving bed, thereby acquiring a high-purity fructo-oligosaccharide solution; and reducing pressure and concentrating the fructo-oligosaccharide solution under ultra-low temperature vacuum, thereby acquiring the fructo-oligosaccharide. According to the method provided by the invention, the continuous efficient separation of fructo-oligosaccharide and monosaccharide and disaccharide can be realized, the high-purity fructo-oligosaccharide can be acquired, the micro-functional sweetening agent is generated by recycling residual components and the comprehensive utilization of the sugaring resource is realized. The method has the advantages of simple operation, high production efficiency, controllable technical index of production process, no pollution, environmental protection and low cost. The industrial production is easily realized.

An ethyl cellulose-based self-healing polymer and a preparation method thereof, which utilizes modified ethyl cellulose containing furan groups and 4,4'-methylenebis(N-phenylmaleyl imine) prepared by the Diels-Alder reaction. Thermoreversible Diels-Alder (DA) bonds can be introduced into self-healing polymers by adjusting the content of 4,4'-bismaleimidodiphenylmethane to obtain polymers with different mechanical properties and self-healing properties Material. Surface cracks in the polymer material can be repaired by heating, and the damaged material can be recycled through a thermoplastic process.

The invention discloses a marine fish peptide containing galangal and a preparation method thereof. The method comprises: mincing marine fish meat into mince, adding water and mixing, enzymolyzing protease to obtain an intermediate product, then adding galangal dry powder and fully mixing, performing enzymatic starch removal and alkali extraction treatment, centrifuging, washing the filter residue with water, and combining The supernatant is concentrated under reduced pressure and spray-dried to obtain marine fish peptides. The total protein content of the marine fish peptide is more than 55%, the proportion of soluble peptides to the total protein is more than 96%, the total sugar content is more than 30%, the proportion of polysaccharides to the total sugar is more than 40%, and the content of galangal flavonoids is more than 0.16‰.
