Prune preserved fruit and production process thereof

Abstract

The invention discloses a prune preserved fruit and a production process thereof, and belongs to the technical field of preserved fruit processing. According to the production process, the productionprocess includes the steps of selection, cleaning, blanching, cooling, piercing, sugar permeability, sugar dripdry, sugar washing-off, baking and softening which are carried out in sequence, wherein the sugar permeability includes the following steps that pierced prunes are soaked in a sugar solution for softening for 1-2 hours, then sugar permeability is carried out by adopting a vacuum sugar permeability and positive pressure sugar permeability cyclic alternating method until the sugar content in the prunes is 55-63 BX, and the sugar permeability is stopped. The preparation method is different from a conventional preserved fruit processing method and is exclusively used for preparing the prune preserved fruit by taking dried prunes as raw materials. Compared with a process of making theprune preserved fruit by using the conventional preserved fruit processing method, the production process has the advantages of greatly saving the sugar permeability time and drying time of prunes, and improving the production efficiency. The prune preserved fruit has the advantages of less loss of nutrient components, better flavor and mouthfeel.

Description

technical field [0001] The invention relates to the technical field of candied fruit processing, more specifically, it relates to a kind of prune preserved fruit and its production process. Background technique [0002] Candied fruit is a general term for many products processed from various fruits and vegetables through different processes such as sugar and salt. It is a folk traditional food with a long history in our country.

Problems solved by technology

[0005] The above-mentioned prior art scheme has the following defects: when infiltrating sugar, first place the peeled prunes in a sugar solution with a mass fraction of 60% to soak for 10-15 hours, and then put them into a citric acid-sugar mixed solution In the process of microwave treatment for 40 to 50 minutes, in the case of removing the thick skin of prunes, the sugar infiltration time is at least 10 hours and 40 minutes, and the sugar infiltration efficiency of prune candied fruit is low
