The potential use of ultraviolet (UV)-C (254nm) to extend postharvest shelf life of fresh unprocessed lotus root (Nelumbo nucifera G.) was determined. UV treatment for 30 and 60min effectively reduced weight loss, improved moisture, color retention, and soluble solids of samples when stored at 25°C for 15days. Microbial growth inhibition of UV was evidenced by 1.8 and 1.0 log reductions in the 30 and 60min-treated samples. Phenylalanine ammonia lyase (PAL) activity and total phenol contents (TPCs) detected in lotus root were higher, while oxid...
