Abstract:
... The postharvest decay of durian (Durio zibethinus Murr.) increases rapidly when the storage time is extended, which seriously limits the commercial value. In this research, the effects of appropriate periodical SO₂ fumigation and different CO₂‐enriched atmospheres (3% O₂ + 10%–13%, 14%–17%, or 18%–21% CO₂) on the storage quality of durian stored at 14°C were investigated. Results showed that SO₂ f ...

Abstract:
... Cloudy apple juice has been treated by thermosonication in batch mode as an alternative processing to thermal treatment. Thermosonication was found to be effective to inactivate polyphenol oxidase; however, pectinmethylesterase was found to be more resistant. An increase of the working ultrasound amplitude and the amount of energy supplied to the juice led to lower enzyme residual activities.Enzym ...

Abstract:
... Supercritical carbon dioxide (SCCD) was applied for the inactivation of tissue enzymes in beetroot juice. The SCCD process parameters had a significant effect on the inactivation kinetics of polyphenol oxidase (PPO), peroxidase (POD), pectin esterase (PE) and polygalacturonase (PG). The use of traditional pasteurization (TP) resulted in a higher level of inactivation of the tested enzymes than SCC ...

Abstract:
... The cultivation of passion fruit in Brazil is impaired due to the high level of infection by soil pathogens that cause premature death. The use of grafting is very promising, using Passiflora giberti as a rootstock and Passiflora edulis f. flavicarpa as a scion. However, the yield is lower than non-grafted plants. By this reason, the use of grafting and maintenance of the two roots are presenting ...

To maintain mushroom quality during storage low O2- (1–5%) and elevated CO2-levels (<12%) are recommended. However, this is not an easy task as mushrooms respire, thereby consuming O2 and releasing CO2. Headspace gas composition was measured daily non-invasively using optically based O2 and CO2 sens ...
