Abstract
The activities of acetylene and ethylene for conservation of sucrose contents of crude sugar and lowering the activity of polyphenol oxidase in sugarcane juice were investigated carrying out separate experiments. Results were compared with the crude sugar produced from an untreated juice and that produced from sulfur dioxide-treated juice, an effective deactivator of the polyphenol oxidase. The sucrose contents of all the samples were determined in terms of the pol% and the change in activity of the polyphenol oxidase was determined in terms of the color intensity of each of the crude sugar sample. The causes of these activities have been discussed in this communication. Practical Applications Acetylene and ethylene gases have been used instead of coloring additives (commonly bleaching powder) for the conservation of sucrose contents in the crude sugar. The bleaching powder has various side effects in terms of depleting quality of the sugar and decreasing the shelf life of the sugar. Thus, the bleaching powder and other coloring agents have been replaced with the acetylene and ethylene gases in the present research work which are blocking the activity of polyphenol oxidase enzyme in the sugarcane juice.
