Volatile compounds and changes in flavour-related enzymes during cold storage of high-intensity pulsed electric field- and heat-processed tomato juices
MetadataShow full item record
The effects of high-intensity pulsed electric field (HIPEF) processing (35 kV cm−1 for 1500 μs, using 4 μs bipolar pulses at 100 Hz) on the production of volatile compounds and flavour-related enzymes in tomato juice were investigated and compared with those of thermal processing (90 ◦C for 30 or 60 s).
