Rapid, simple technique for preparing blackberry clear juice

Abstract

A technique for fast and convenient preparation of clear blackberry juice is provided, which relates to the processing method for preparing clear fruit juice from fresh blackberry. The invention, which combines the machineries in series, comprising air bubble cleaner arrow spraying cleaner arrow conveyance and selection belt arrow steam heating tunnel arrow pulping and seed picking machine arrow instant sterilization machine (or pasteurization) arrow quantitative canning machine, processes fresh blackberry into fruit pulp with speed and then store the pulp in low temperature, so as to resolve the problems of concentrated collection period of berry, overstock and rotting of fruit in the producing area of blackberry. When there are market demands, carry out clearing process of fruit pulp. Clearing of fruit pulp: take xanthan gum or pectin as clearing agent with the dose of 0.10 to 0.50 per cent to the weight of fruit pulp; dilute the clearing agent with water for 1.0 to 2.5 times; grind the pulp for 1 to 3 times and keep it under ambient temperature for 5 to 12 hours. Therefore, the processing method in the invention, with excellent economic and practical performance and easy to be mastered, can be best applied in medium and small size fruit product processing enterprises that take fresh blackberry as raw materials in the producing area of blackberry.

Description

technical field [0001] The invention relates to the technical field of fruit processing, and relates to a processing method for preparing clarified fruit juice from fresh blackberry fruit.
