Changes in quality attributes of pulsed light treated dehydrated onion shreds during storage

Journal of Agriculture and Food Research, 2023
Processing of dehydrated onion shreds involves contamination during peeling, chopping, and dehydration. Pre-treatments such as blanching, dipping and soaking in chemical solutions reduce the contamination prior to dehydration. Post dehydration treatments
