Abstract

The invention belongs to the technical field of food processing, and provides a concentrated fruit and vegetable juice, and a processing method thereof. The processing method comprises following steps: fruit and vegetable juice is subjected to refrigeration for 20 to 30h at -20 to -18 DEG C, the refrigerated fruit and vegetable juice is subjected to unfreezing draining at vacuum conditions, thawedliquid is collected in different batches so as to obtain liquids with different primary sweet degrees, the liquids with sweet degrees lower than a preset sweet degree are subjected to the above refrigeration and vacuum unfreezing process for another time, thawed liquid is collected in different batches so as to obtain liquids with different second sweet degrees, and the above operation is repeated until liquid concentration reaches the preset sweet degree so as to obtain the concentrated fruit and vegetable juice, the concentrated fruit and vegetable juice is stored at -20 to -18 DEG C, and is subjected to disinfection processing. The whole concentration process and the disinfection process are carried out at relatively low temperature, fruit and vegetable juice nutritional components andfragrant components are protected as far as possible in concentration process, the concentrated fruit and vegetable juice prepared through processing is excellent in quality, and small in size, and is convenient for transportation.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a concentrated fruit and vegetable juice and a processing method thereof. Background technique [0002] Fruit and vegetable juice is the juice squeezed from vegetables and fruits. It is rich in antioxidants. Fruits and vegetables have high nutritional value and provide our body with nutrition, energy and health in an empty stomach. Raw juice supplies the human body with a large amount of vitamins, minerals and enzymes. The phytochemicals in it help us remove carcinogens from the body. However, freshly squeezed fruit juice has a large water content and a large volume, is not easy to transport, and is easy to deteriorate, has a short storage time, and easily loses nutrients, which is not conducive to mass production. Contents of the invention [0003] The object of the present invention is to provide a processing method of concentrated fruit and vegetable juice, which h...
