Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in the existing production process of canned pears, the surface oxidation of pears is prone to occur, which affects the color of the final pears. If high-temperature cooking is used to achieve the effect of inactivating enzymes, it is easy to affect the mouthfeel of the final canned food

Abstract

The invention discloses a processing technology of canned pears. The processing technology of the canned pears comprises the following production steps: performing pretreatment on raw materials, namely pears; carrying out cold water treatment; carrying out ultrasonic enzyme inactivation; preparing auxiliary materials; and then, carrying out sealing and sterilizing. The processing technology of thecanned pears has the following beneficial effects: by carrying out cold water treatment and ultrasonic enzyme inactivation, the finally processed canned pears are relatively close to natural color interms of color and luster, as well as free of the phenomenon of oxidation; and moreover, excellent enzyme inactivation effects are achieved. In addition, the canned pears processed by the processingtechnology are free of steamed smell, relatively mellow in natural aroma, complete in shape, and appropriate in hardness.

Description

technical field [0001] The invention belongs to the field of canned pear processing, and in particular relates to a canned pear processing technology. Background technique [0002] Canned fruit is named differently depending on the material used. Generally, the raw materials of canned fruit are derived from fruits, including pears, yellow peaches, apples, lychees, strawberries, hawthorns, etc. [0003] Both food and cans need to be sterilized. After the bacteria and bacterial spores are eliminated, there will be no bacteria to reproduce. However, it is unlikely that all of them will be eliminated. What can be achieved is basic sterilization, so as to prolong the storage time of food as much as possible. There are also a lot of bacteria and bacterial spores in the dust and so on in the air. The bacterial spores are like the seeds of trees, which are very durable and can be blown by the wind. So the cans are all vacuum sealed. There are preservatives in the cans, because ba...
