Optimization of process conditions for chitosan on apple juice making as a clarifying agent

Abstract

On the expansion of chitosan to the squeezed apple as a clearing up operator at various focuses (10-250 mg/ml) and differing time (30– 150 min) and temperature (20– 40 °C) mixes. In this methodology, chitosan fixation, process time and procedure temperature are named as free factor parameters; turbidity (NTU) and shading (%T440) were settled as reaction. The Box – Benken technique was utilized to ponder the outcome of these medicines which greatly affects the turbidity and shading. From the investigation, the elucidation treatment for the ideal states of the squeezed apple illumination are 226.532 mg/100ml of chitosan focus at 35.8℃ Process temperature for 30.5 min Process time according to the reaction surface procedure and the shape plots.Keyword: Response surface methodology, chitosan concentration, Clarification, Apple juice, process time, process temperature, turbidity and colour.
