Paneer, a milk product coagulated by heat and acid, typically has a short shelf-life of one day at room temperature thus restricting its availability in the market. In this study, efforts were made to prolong its shelf-life at room temperature by applying an edible coating made from condensed whey mixed with antimicrobials (lactic acid and potassium sorbate). The condensed whey, concentrated to 45 per cent total solids, was combined with four percent glycerol as a plasticizer. A solution containing lactic acid and potassium sorbate (25per cent strength) was added at a 12per cent level to the condensed whey. Samples coated with this mixture and packaged in LDPE pouches showed a shelf-life of four days under ambient conditions. The standard plate count, coliform count and yeast and mould count expressed in Log10cfu/g at the end of fourth day for this sample were 3.72 ± 0.026, 2.63 ± 0.047 and 2.42 ± 0.058 respectively and were within the FSSAI limits prescribed for paneer. This confirms the antimicrobial effect of the coating applied. The analysis of the samples’ physicochemical properties indicated that the studied edible coating effectively prevented an undesirable rise in titratable acidity and helped maintain the product’s moisture content. There was no significant difference observed in shelf-life between samples packaged using atmospheric and vacuum conditions; both methods provided a shelf-life of four days.
