  • Publication number: 20250074953
    Abstract: A method for modifying a gliadin and an application thereof are provided. The method includes the following steps: dissolving the gliadin in a solvent to obtain gliadin solution; and adding a proline endoprotease to the gliadin solution for a reaction, and adjusting the pH value of solution to neutral according to a gradient, to obtain a modified gliadin. The modified gliadin obtained by the present invention may be uniformly dispersed in water, and may still maintain a uniform dispersion state in the water after high-temperature thermal sterilization and long-term storage, or even in the presence of sodium chloride, it has good thermal stability, salt resistance, and storage stability.

  • Publication number: 20210341550
    Abstract: Disclosed are a non-to-the-home type device and method for detecting electric meter misconnection based on the PLC communication technology and using multiple frequencies. The detection device includes a master detection device and a slave detection device. The master detection device acquires address information of different electric meters at the outlet terminals of the electric meters by using RS485 communication. The modulation circuit modulates the communication address information of different electric meters into high-frequency carrier signals of different frequencies, and sends the high-frequency carrier signals to user sides by using the PLC communication technology. A line trap is provided between the modulation circuit and the electric meters. The slave detection device has a high-frequency carrier signal detection antenna.
