Author(s): Ranjit Singh and Ananda Kumar S
Abstract: Coriander (Coriandrum sativum) the spice comes under minor aromatic annual condiment spice crop. Coriander leaves and fruits are used in flavouring food and to suppress offensive odours in pharmaceutical preparations. Several insect damage dried coriander fruits during storage. Among the insects, cigarette beetle (Stegobium paniceum) is important one. Now a day, ozone fumigation is gaining interest because it can be generated on the treatment site also not produce any residue after the treatment. In the study, four life stages of drug store beetle such as adult, pupa, larva and egg were fumigated in lab-scale canisters by ozone at different concentrations like 150, 250 and 350ppm to achieve 100 per cent mortality. From the results, it is observed that the adult insect has taken 578min to attain LT99 at 250 ppm. Similarly, for pupa and larva the 99 per cent mortality was achieved at 1083min and 609min respectively. The ozone treated (250ppm) coriander samples were kept in airtight plastic containers and storage studies were conducted for 105 days. During the storage, it was observed that there was significant decrease in the quality parameters of protein, colour b value and linalool content. The respective quality value of 250ppm treated coriander on the 105th day of storage were found as protein 12.25 per cent; colour (b value) 23.71 and linalool content reduced to 37.48 per cent.
