Abstract: Process of easy-instant spinach-egg-soup with freeze-drying technology was introduced，optimum technical condition were explored as follow： temperature of pre-freezing was -30 ℃，during period of sublimation drying，cryo-temperature was -30 ℃，sublimation temperature was -18 ℃，pressure of chamber was 60 Pa，it continued 10 h，during period of desorption drying，temperature of board was 8 ℃，pressure of chamber was 100 Pa，it continued 7 h.Results showed that easy-instant spinach-egg-soup with freezing-drying technology were nutrient-rich，unique flavor and convenient.
