The invention relates to a preparation method of soluble sugar substitute based on Jinxiu sweet tea pigment, and belongs to the technical field of food processing and natural product extraction.The preparation method comprises the steps that Jinxiu sweet tea leaves serve as raw materials, and composite enzymolysis, hot water extraction, membrane separation and concentration, stable blending and spray drying are sequentially conducted. The method comprises the following steps: synergistically releasing sweet taste and pigment components through enzymolysis and extraction, purifying and concentrating through a membrane technology, and protecting through a stabilizer system to finally obtain a powdery product. The sugar substitute has high sweetness and stable brownish red color, realizes integration of sugar and color, can be used as a natural sweetening agent and a coloring agent to be directly used in milk tea, coffee and other food beverages, simplifies the formula and process, and meets the label cleaning requirements.

This utility model relates to a flexible photovoltaic support for vertically mounting steel frame components, comprising end members, a middle member, steel cables, wind-resistant members, and fixing members. The end members are located at both ends of the entire support and are fixedly connected to the ground; the middle member is located in the middle of the entire support and is fixedly connected to the ground; one end of the steel cable is connected to one of the end members and the other end passes through the middle member and is connected to the other end of the end member, wherein two sets of steel cables are provided; one end of the wind-resistant member is connected to the steel cable and the other end is fixedly connected to the bottom ends of the end members and the middle member; the fixing member is slidably connected to the steel cable and one end is connected to the steel frame component. This flexible photovoltaic support for vertically mounting steel frame components replaces the photovoltaic support used in traditional photovoltaic installations, avoiding the problem of insufficient adaptability to various scenarios, resulting in low economic efficiency of photovoltaic module power generation.

The invention discloses an MOFs-based blood perfusion adsorption material and a preparation method thereof, and relates to the technical field of blood perfusion, the adsorption material takes a melt-blown non-woven fabric as a matrix, in-situ growth of an adsorbent MOFs and heparin connected with an MOFs organic ligand in a covalent bond mode is carried out on the surface of the melt-blown non-woven fabric, the gram weight of the melt-blown non-woven fabric is 30-200g / m < 2 >, and the fiber diameter is 0.3-7.5 [mu] m. The hemolysis rate of the MOFs-based blood perfusion adsorption material is kept within 10%, the MOFs-based blood perfusion adsorption material has good biocompatibility, the selected melt-blown cloth base body has good biocompatibility and high porosity, part of protein binding elements with large particle sizes can be preliminarily screened out, the MOFs-based blood perfusion adsorption material shows excellent adsorption performance for various toxins in blood, and the MOFs-based blood perfusion adsorption material is suitable for being applied to various toxins in blood. The excellent anticoagulation effect is realized.
