Sterilizing method for mango pulp

Abstract

The invention discloses a sterilizing method for mango pulp, which mainly comprises the following steps: (1), cleaning the surfaces of mangos; (2), sterilizing the surfaces of the mangos; (3), blanching the surfaces of the mangos; (4) pulping; (5), sterilizing: using a plate type or a tube-type sterilizing machine to sterilize mango pulp obtained after pulping within 80 to 90 seconds at a temperature of 70 to 80 DEG C; (6), cooling quickly: using a coiled pipe cooler to cool mango primary pulp obtained after sterilization within 30 to 60 seconds to be at a temperature lower than 15 DEG C; (7), carrying out sterile filling; (8), carrying out cold storage at a temperature of 18 DEG C below zero. The traditional sterilizing method adopts high temperature sterilization which enables the color of the mango pulp to be changed and the mango pulp spice to be lost. The other method is that the mango pulp is placed in an environment at the temperature of 18 DEG C below zero, even mango spice is kept, but hygienic indexes exceeding standard can be easily caused by that the sterilization is not performed. According to the method provided by the invention, bacteria in mango pulp can be killed efficiently, so that microorganism indexes reach national standards; the natural mango spice is kept completely.
