Abstract
Papad is a popular traditional Indian snack food that is also consumed as an accompaniment to meals. The papad industry in India is predominantly a cottage industry, mainly run by women. Due to microbial contamination and infestation, papad has a shelf life of only a few months. However, increased domestic consumption and export requirements necessitate a longer shelf life. Chemical preservatives are generally added to increase shelf life. Our studies have shown that radiation processing (2 kGy) can be used to extend the shelf life. Unirradiated samples spoiled in three months with visible fungal growth and insect infestation. Irradiated (2 kGy) papad had a shelf life of one year, was sensorily acceptable, showed no microbial counts, and hence has great export potential.
