Abstract:
Paneer is a very popular coagulated milk product but like other dairy products it is very perishable. Thus, a study was conducted to extend the shelf life of paneer packed with clove and oregano essential oil treated starch and carboxymethyl cellulose (CMC) based edible packaging film. Starch and CMC based edible packaging film was prepared by adding starch (5 g), carboxymethyl cellulose (15% W/W starch) and glycerol (40 ml/100 g starch) in distilled water (100 mL) and then clove and oregano essential oil was incorporated before drying. Control paneer sample and paneer samples packed in clove and oregano essential oil treated edible packaging film showed significant (p<0.05) decrease in physico-chemical, microbiological and overall sensory properties throughout the storage period but under desirable limit. Control paneer sample was found bland on 5^th day of sensory evaluation and microbiologically unfit on 9^th day of storage. Paneer samples packed in clove and oregano essential oil treated edible packaging film was found undesirable on 10^th day of sensory evaluation but found microbiologically fine at 12^th day of storage. The results revealed that clove and oregano essential oil treated edible packaging film extended the shelf life of paneer at least by 4 days as compared to control that was found microbiologically unfit for consumption on 9^th of storage at 4±1 °C.
