Abstract: A Pickering particle dry powder and a preparation method are used in food processing. The preparation method includes stirring peanut protein isolate and water as raw materials to obtain peanut protein isolate dispersion, subjecting the peanut protein isolate dispersion to ultrasonic treatment, subjecting the resultant to cross-linking reaction with transglutaminase to obtain a monolithic geld, shearing and homogenizing the monolithic gel to obtain a microgel particle dispersion, spray drying the microgel particle dispersion to obtain the Pickering particle dry powder. The Pickering particle dry powder prepared by the ultrasonic-assisted enzyme method is still in nanometer level after rehydration, which is beneficial to preparing Pickering emulsion with strong stability. The preparation method has the advantages of simple operation and low cost, which is beneficial to actual production in the food industry.

Abstract: Embodiments of the present invention provide a method, system and DNS server for load balancing network servers. The method includes: monitoring whether each network server is capable of providing a network service, deleting an IP address of a network server which is incapable of providing a network service from an IP list in a DNS server or setting the IP address as invalid in the IP list according to a monitoring result; receiving, by the DNS server, a request from a network user for accessing a network server, selecting an IP address from valid IP addresses in the IP list which corresponds to the request; providing, by a network server having the selected IP address, network services for the network user.
