Abstract/ Executive Summary:

An experiment was carried out at Physiology and Sugar Chemistry Laboratory of Bangladesh Sugarcane Research Institute Ishurdi, Pabna, Bangladesh during 2013-2014 to determine the self life of sugarcane juice without adding any preservatives. Sugarcane varieties Isd 34, Isd 35, Isd 36, Isd 37 and Isd 38 were used for collection of juice and juice were collected in the month of September, October, November, December, January, February and March. Juice collected in the month of December and January showed the highest shelflife by using Mucilage substances of ladies finger (Hibiscus esculentus Linn) as a clarificant. Juice collected in the month of December, January showed highest self life due to presence of lower reducing sugar and highest percentage of sucrose.

Program Area: Quality and Nutrition

Commodity: Juice

Objectives:

To establish a protocol for preservation of sugarcane juice without adding any preservatives.

Methodology:

Many commercial juices are filtered to remove fiber. Common methods for preservation and processing of fruit juices include canning, pasteurization, freezing, evaporation, drying and addition of preservatives. A different method was followed for preservation of cane juice. Collection of Sugarcane Juice: Six sugarcane varieties viz. Isd 34, Isd 36, Isd 37, Isd 38, Isd 39 and Isd 40 were used. 11 months aged canes were collected from the field. Then they were washed and collect the juice using a hand crusher. Preparation of Ladies Finger Extract and Mixing into Juice: First we collected the ladies finger plant. We cut the stem into pieces. Then we collect the outer layer of the stem and put into water for 30 minutes. Mucilage substances came out from stem and mixed with water. 250-300 gm extracts are used as clarificant for 180 liter sugarcane juice. Juices were then boiled at 100⁰C for 10 minutes. During boiling mucilage substances which were collected from ladies finger were mixed with juice. After mixing the extract all the dirty substances and fiber became clod together. Then we removed them completely. Thus we got a clear and transparent juice. Then the juices were bottled after cooling in germfree airtight bottles using laminar flow chamber and preserved for four months in room temperature (25⁰C). Analysis the Juice Before and After Preservation: Juices were analysed before preservation and every 15 days after one bottle were analyzed for determination of qualitative characters like bix, pol, purity, reducing sugar. Microbial tests were also done after every 15 days. 2.4. Determination of Brix, Pol, Purity and Reducing Sugar Soluble solids (0Brix) was determined by Brix hydrometer standardized at 20°C and Horne’s dry lead method was used for sucrose determination using an automatic polarimeter (Bellingham and Stanley ADP-220®). Juice purity was calculated as the ratio of the sucrose content and corrected Brix reading. Reducing sugars were determined by the method described in Queensland Laboratory Manual [Bureau Sugar Experiment Stations. Statistical Analysis: The collected data for a character under certain treatment were calculated and statistically analyzed following Factorial Completely Randomized Design (CRD). The analysis of variance was performed and means were compared by Duncans New Multiple Range Test (DMRT) at 5% level of probability for interpretation of results.

Achievement/Findings:

Juice collected in the month of December and January showed the highest shelflife by using Mucilage substances of ladies finger (Hibiscus esculentus Linn) as a clarificant. Juice collected in the month of December, January showed highest self life due to presence of lower reducing sugar and highest percentage of sucrose.
