Peanut protein is one of the major plant protein resources in China. The lacking of processing-special varieties seriously hampered the healthy development of peanut processing industry. We took the arahcin extracted from the mutant peanut lines as research material and investigated the basic physico-chemical properties of arachin with/without this subunit. On the basis of the results of physico-chemical properties, the thermal property was selected as research focus and the thermal properties and structure...
