The invention discloses a jade butterfly nut potato mash which comprises the following raw materials in parts by weight: 20-22 parts of mung bean, 18-20 parts of pistachio nuts, 5-6 parts of cookies, 8-9 parts of soybean milk, 1.3-2.3 parts of jade butterfly, 1.5-2.1 parts of mountain mint, 1.3-2 parts of pearl fruit, 200-230 parts of potato, 100-120 parts of streaky pork, 8-10 parts of salt, 3-4 parts of chilli powder, 2-3 parts of pepper powder, 2-3 parts of sodium carboxymethylcellulose, 1-1.2mol/l NaOH, 100-150 parts of selenium-rich peanuts, 0.1-0.15 parts of succinic anhydride and a defined amount of phosphate buffer and petroleum ether. In the jade butterfly nut potato mash, sodium carboxymethylcellulose and peanut protein isolate have glycosylation reaction, so as to form a covalent compound capable of maintaining the excellent emulsification property of food at high temperature, prolonging polypeptide chain, enhancing steric effect and enhancing the heat stability of the compound.
