Abstract

The invention discloses a fresh-keeping processing and packaging process for fresh-cut shredded potatoes. The process comprises the following steps: sorting fresh potatoes according to different grades, peeling and shredding (or dicing or slicing) the potatoes, and cleaning the potatoes in a bubbling washing machine for 10min; sterilizing the potatoes in ozone water with O3 concentration of 3ppm, while controlling the ozone water temperature at 10 DEG C and adjusting the pH value of the ozone water at 5, and soaking for 15min; taking out the shredded potatoes, immediately immersing the shredded potatoes into a mixed solution containing 25% of VC and 0.5% of citric acid for 10 minutes, and centrifuging the shredded potatoes in a 1200r centrifuge for 40 s to drain the water; and filling the drained shredded potatoes into a sterile polypropylene box, and packaging the fruits by a controlled atmosphere packaging method. According to the above process provided by the invention, a fresh-keeping period of the fresh-cut shredded potatoes reaches up to 10 days, without loss of section color or taste of the shredded potatoes.

Description

technical field [0001] The invention relates to the field of fresh-keeping processing, in particular to a fresh-keeping processing and packaging technology that can be used for fresh-cut potato shreds. Background technique [0002] Potato is an important vegetable variety that people eat daily, and its output and consumption both rank in the forefront of various vegetables. During the processing of fresh-cut potatoes, the peeling and cutting processes have caused damage to the potato tissue, not only losing its integrity and metabolic coordination, but also causing irreparable damage to the whole body without self-protection, and the cell tissue is completely in contact with the air. It is very prone to browning and odor, which seriously affects its sensory quality and nutritional value. [0003] Also do not see the technical scheme that fresh-cut potato product is carried out fresh-keeping at present, and existing fresh-cut potato product adopts the method for cutting and ...
