Paneer is an indigenous coagulated milk product, but like other indigenous dairy products, is highly perishable, with a limited shelf-life. Thus, a study was conducted to extend the shelf life of paneer with the addition of plant essential oil i.e. cinnamon oil and stored in different packaging materials. The stored paneer samples showed highly significantly (P<0.01) decrease in moisture and increase in titratable acidity, free fat content and tyrosine content, but within normal extent. The microbiological count of control samples increased highly significant (P<0.01) throughout the storage period, but within the BIS specifications, while the standard plate count of paneer samples treated with cinnamon decreased highly significantly (P<0.01). There was no major perceivable defect observed in stored samples, except control, but the decrease in flavour score to less than 6.0 during storage limited their shelf life. On decreased flavour basis, control paneer samples showed shelf life of only 10 days with metalized polyester, 8 days with nylon and 5 days with LDPE, while cinnamon treated samples showed shelf life of 18 days with metalized polyester, 14 days with nylon and 9 days with LDPE at 8±1ºC.
