Abstract
A method of processing raw sugar cane juice, comprising: reducing the pH of the sugar cane juice to a pH at which microbiological activity is substantially eliminated; separating chlorophyll from the sugar cane juice; separating particles having a diameter greater than 0.5 microns from the sugar cane juice; denaturing polyphenol oxidase (PPO) in the sugar cane juice by pasteurisation; separating the denatured polyphenol oxidase from the sugar cane juice.

A method of processing raw sugar cane juice, comprising:
- reducing the pH of the sugar cane juice to a pH at which microbiological activity is substantially eliminated;
- separating chlorophyll from the sugar cane juice;
- separating particles having a diameter greater than 0.5 microns from the sugar cane juice;

A system for processing raw sugar cane juice, comprising:
- an acidification unit for reducing the pH of the sugar cane juice to a pH at which microbiological activity is substantially eliminated;
- a first separation unit for separating chlorophyll from the sugar cane juice;
- a second separation unit for separating particles having a diameter greater than 0.5 microns from the sugar cane juice;
- a pasteurisation unit for denaturing polyphenol oxidase (PPO) in the sugar cane juice by pasteurisation;
- a third separation unit for separating the denatured polyphenol oxidase from the sugar cane juice;
- and a heater for heating the reduced pH sugar cane juice to between 50° C. and 70° C. before separating the chlorophyll from the reduced pH sugar cane juice.
