In the present study, combination of essential oils (EOs) and packaging materials were evaluated to increase the storage stability of burfi. Combination of turmeric (@ 100 ppm), ginger (@ 200 ppm) and cardamom (@ 300 ppm) EO was incorporated into burfi to exploit their synergistic activity. Burfi samples were packaged in cardboard or HDPE boxes and stored at 37 ± 1 and 4 ± 1 °C. The samples were evaluated for changes in anti-oxidant, physico-chemical, instrumental color, microbiological and sensory attributes. Free radical (ABTS and DPPH) scavenging activity remained significantly (p < 0.05) higher in EOs added and HDPE boxes packaged burfi during the storage period. Extent of lipid oxidation (TBA value) was higher in control sample packaged in cardboard boxes. Change in instrumental color values (L*, a*, b*) were higher in both the samples packaged in cardboard boxes. Decrease in moisture content and water activity was higher for cardboard packaged samples. Increase in total, and yeast and mold count was significantly (p < 0.05) lowered by EOs incorporation in both the packaging materials. Samples packaged in HDPE boxes had lower (p < 0.05) microbial counts after 4th day at 37 ± 1 °C and 10th day at 4 ± 1 °C temperature. Titratable acidity was lower (p < 0.05) in EO added samples. At 4 ± 1 °C, cardboard and HDPE boxes packaged samples were sensorially acceptable up to 15 and 25 days, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
