In the present study, changes in compositional, physico-chemical, rheological, sensory and microbial properties (SPC, coliform count and yeast and mould count) of rava burfi packed in composite polyethylene terephthalate (PET)/low density polyethylene (LDPE) film was monitored during storage at room temperature (30Â± 2 Â°C) and refrigerated temperature (7Â±2 Â°C) on every 3 rd for room temperature and on every 7th day for refrigerated temperature of storage till the products became unacceptable. All the changes related to composition, acidity, water activity, Free Fatty Acid (FFA), soluble nitrogen, 5-Hydroxy Methyl Furfural (HMF) and Thiobarbituric Acid (TBA), rheological, sensory and microbiological properties of rava burfi were found to be significantly (P<0.05) affected by storage period (i.e. 9 days at room temperature (30Â±2 Â°C) and 35 days at refrigerated (7Â±2Â°C) temperat ure). During storage period there was a decrease in moisture content (2.5 to 3.0%) and water activity and an increase in fat, protein, lactose, ash, added sugar, acidity, FFA, soluble nitrogen, TBA and HMF both at ambient (30Â±2 Â°C) a s well as at refrigerated (7Â±2Â°C) temperature. Changes in rhe ological attributes at both ambient and refrigerated temperatures of storage indicated that there was an increase in hardness, gumminess, chewiness and adhesiveness whereas there was decrease in cohesiveness and springiness values. The sensory scores in terms of flavour, body and texture, colour and appearance and overall acceptability were found to be significantly (P<0.05) decrease with progressive increase in storage period. The shelf life of rava burfi was found to be 9 days at room temperature (30Â±2 Â°C) and 35 days at refrigerated (7Â±2Â°C) temperature.
