Problems solved by technology

[0002] With the development of fruit fresh-keeping technology, a large number of off-season vegetables and fruits are supplied to the market, and good economic benefits have been achieved. However, the problem caused by the large-scale use of fresh-keeping agents or fresh-keeping packaging materials is the residue and flooding of chemicals. Life poses a potential threat, and some fruits can be processed for a very short time, such as peaches, apricots, etc., so it is urgent to design a fruit freezing processing method

Embodiment 1

[0018] A kind of fruit frozen processing method, it comprises the following steps:

[0019] (1) Raw material selection: choose fresh fruits with uniform size, no pests and diseases, no mechanical damage, no rot, normal color, moderate maturity and suitable for freezing processing as raw materials;

[0020] (2) Cooling: put the fruit into cold water at 0-5°C for 15-20 minutes, and perform preliminary cooling treatment;

[0021] (3) Cleaning: clean the fresh fruit, remove dirt and impurities, drain and set aside;

[0022] (4) Slicing: Peel and core the cleaned fruit slices, and the fruit can be cut into slices, triangles or squares;

[0023] (5) Color protection: put the sliced ​​fruit into the color protection solution and soak for 10-15min to protect the color;

[0024] (6) Sweetening: put the color-protected fruit into the sugar solution to increase the sweetness;

[0025] (4) Freezing: put the fruit slices into a vacuum environment at -45 to -40°C and freeze for 6 to 24 h...

Abstract

The invention discloses a fruit freezing processing method. The fruit freezing processing method comprises the following steps of (1), raw material selection, (2), cooling, (3), cleaning, (4), slicing, (5), color protecting, (6), sweetening, (7) freezing, (8) drying and (6), packaging. According to the fruit freezing processing method, the freezing process is adopted to enable fresh fruits to dryat low temperature, and original color, flavor and quality are kept, so that the fruit quality is effectively maintained, the loss is reduced, the regional and seasonal supply is regulated, and the purpose of long-term storage, convenient consumption and delayed consumption is achieved.

Description

technical field [0001] The invention relates to the technical field of fruit processing, in particular to a fruit freezing processing method. Background technique [0002] With the development of fruit fresh-keeping technology, a large number of off-season vegetables and fruits are supplied to the market, and good economic benefits have been achieved.
