The invention discloses a method for extracting longan pulp polysaccharide. The method comprises the following steps of (1) slurrying and slurry treatment: mixing fresh longan pulp and purified water, pouring a mixture into a homogenizer for slurrying, adding alkali liquor and activating at -4 to 10 DEG C for 10-12 hours to obtain an activated liquid; (2) enzymolysis and concentrating treatment: adjusting the pH value of filtrate, adding a copper oxide-zirconium oxide catalyst and ternary complex enzyme to filtrate, carrying out enzymolysis under the condition of 200-500W of microwave irradiation and then carrying out ultra-filtration concentration on enzymatic hydrolysate obtained through enzymolysis; (3) centrifugal treatment: mixing a concentrated liquid and a mixed alcohol solution, and collecting an educt by adopting a centrifugal machine; and (4) spray drying treatment. An alkali liquor low-temperature activating enzyme association technology is introduced into an extraction preparation process of the longan polysaccharide; the yield of a target product is obviously improved in comparison with a conventional technology; and meanwhile, the method has the characteristics of being efficient, fast, low in cost and suitable for massive industrial production.

The invention provides a method for preparing CNT-Cu composite powder by a solution combustion method, and relates to the field of composite material preparation. The method comprises the following steps that (1), copper nitrate, functionalized carbon nanotubes, cane sugar and deionized water are mixed, and then subjected to ultrasonic stirring for 30 minutes to enable all the components to be uniformly mixed to obtain a mixed solution; (2), the mixed solution obtained in the step (1) is poured into a corundum crucible to be heated, and the mixed solution is combusted to obtain precursor composite powder after undergoing water evaporation, boiling and bubbling; and (3), the precursor powder obtained through combustion of the solution in the step (2) is reduced to obtain the carbon nanotubecopper composite powder by adopting a reduction process in an aqueous solution powder mixing method. According to the method for preparing the CNT-Cu composite powder by the solution combustion method, the process is simple, the reaction is rapid, the efficiency is high, the cost is low, the product purity is high, all the components can achieve uniform mixing on the molecular level, moreover, inthe combustion process, the material experiences relatively large temperature change in a short time and then possibly generates a metastable phase, and then the phase-to-phase bonding strength can be improved.
