The invention discloses a fruit freshness preservation method. The fruit freshness preservation method disclosed by the invention comprises the following steps of firstly, putting fruits into a vacuumdrying box of which the vacuum degree is 0.08MPa and the temperature is 40-50 DEG C, and carrying out treatment for 30 minutes so as to remove superfluous water from the fruits by performing vacuum drying; and then, sending the treated fruits into a thermostat box so as to reduce the temperature to 18 DEG C below zero at a cooling rate of 10-15 DEG C/minute, maintaining the temperature for one hour, and sending the cooled fruits into a cold storage so as to carry out storing. The fruit freshness preservation method is capable of ensuring wholeness of fruit cells, as well as significant in freshness preservation effects. The fruit freshness preservation method is capable of prolonging freshness preservation cycle of the fruits, as well as ensuring convenient storage and transportation of the fruits; moreover, the fruit freshness preservation method is also capable of avoiding cell rupture of the fruits caused by large ice crystals produced by water, and thus, the fruit freshness preservation method is capable of perfectly preserving edible taste and nutritional values of the fruits.
