Effect of Some Indian Herbs and Chemical on Shelf Life of Sugarcane Juice
Subscribe/Renew Journal
The present study was carried out to provide hygienic, shelf-stable sugarcane juice to people and encourage the industrialists to start sugarcane juice production on commercial scale. Different lots of sugarcane juice were subjected to heat treatment at 75°C for 15 minutes (T1). Heat treatment after addition of lemon juice + ginger + Pudina extracts + black salt (T2), heat treatment after addition of lemon juice + ginger + Tulsi extracts + black salt (T3), heat treatment after addition of 0.04 per cent propyl parabens (T4) and heat treatment after addition of 0.06 per cent propyl parabens (T5). Fresh sugarcane juice was taken as control (T0). All the treated juices were bottled and were pasteurized in hot water at 75°C for 15 minutes. All the lots were stored for 30 days at room temperature (30 ± 5°C).The prepared juice were observed for physico-chemical and microbiological aspects like T.S.S, pH, colour, total plate counts, yeast and mould growth along with sensory evaluation.The experiment was laid down using Completely Randomized Design.From the experiment it was clear that the overall performance of the above characteristics was found best when the juice was preserved by using heat treatment after addition of 0.04 per cent propyl parabens (T4). However, the use of Pudina in the treatment T3 and Tulsi in the treatment T4 have shown the maximum values of sensory attributes upto the interval of 5 days as compared to others.
