The invention relates to a
processing method of chilled fruit and vegetable juice, and belongs to the technical field of fruit and vegetable juice
processing technologies and preservation. Fruit and vegetable juice obtained by squeezing fresh
fruits and vegetables is filtered and then transferred to a
refrigeration house to be frozen into a
solid state (hereinafter referred to as an ice body) for low-temperature
cryopreservation. When needed, the fruit and vegetable juice ice body is heated and dissolved, and the fruit and vegetable juice is recovered. According to the method, the fresh fruit and vegetable juice obtained by squeezing fresh
fruits and vegetables is frozen into the fruit and vegetable juice ice body in time for low-temperature storage, so that the
shelf life and the refreshing time of the fresh fruit and vegetable juice are prolonged. When the fruit and vegetable juice ice body is heated and dissolved, high-concentration fruit and vegetable juice (low in
melting point) is dissolved firstly, and the remaining ice body is mainly ice (crystals) formed by water when the fruit and vegetable juice ice body is dissolved to the final stage. The
melting point of the ice (
crystal) is 0 DEG C, and the temperature of the ice (
crystal) is kept at the
melting point in the dissolving process. Namely, in the process that the fruit and vegetable juice ice body recovers
dissolution of the
fruit juice, the dissolved fruit and vegetable juice is in a low-temperature state (even in a heating state), bad biochemical changes are prevented from being generated, and the original quality and
flavor of the fruit and vegetable juice are protected. The method disclosed by the invention solves the problems of long-term preservation and fresh keeping in the production process of the fruit and vegetable juice, can meet the
processing requirements of fruit and vegetable juice products or various products taking the fruit and vegetable juice as raw materials in seasonal seasons of non-
fruits and vegetables, and provides a new path for optimizing a
deep processing technology of the fruit and vegetable industry. The process method is simple to operate, energy-saving and high in efficiency, and can be used for processing and producing fruit and vegetable juice products.
