Effect of Zataria multiflora essential oil and potassium sorbate on inoculated Listeria monocytogenes , microbial and chemical quality of raw trout fillet during refrigerator storage

The color of fresh pistachio is used as a postharvest quality indicator. The present study was performed to investigate the chemical properties of fresh pistachios coated with different sodium alginate concentrations (1 and 1.5%), various amounts of Shirazi thyme essential oil (0.3 and 0.5%), and their combination during storage (2 ± 1°C and 85 ± 5% RH). Over the storage duration, chemical parameters were measured on days 13, 26, and 39. The results showed that although the application of sodium alginate in combination with thyme essential oil decreased polyphenol oxidase activity in comparison with other treatments, the highest total phenolics and phenylalanine ammonia lyase activity were found in pistachios coated with alginate (1%) + thyme essential oil (0.3% and 0.5%). In general, it was proven that treatments containing 1% alginate + 0.3% essential oil had the ability to maintain the quality of fresh pistachio fruit approximately over 39 days of storage.

Eucalyptus Sideroxylon

The main objective of this work is to determine the effect of the harvest period on the yield and chemical quality of the essential oils of the Eucalyptus sideroxylon A. Cunn. leaves of the Mamora forest, Dayet Zerzour Bnifdel region, Rabat. Essential oil yields are remarkably high above 2.3%, with an ultimate rate of 5.48% for the month of April. The chemical quality of these essential oils is characterized by the presence of two major monoterpenes, 1,8-cineole (eucalyptol) and α-terpineol, which are proportionally inverted in terms of quantity. During the wet months between September and March, the cineole predominates with levels ranging from 72.67% to 86.11% and the other dry months are characterized by an increase of α-terpineol rate from 12.05% to 25.61%. This inverted chemical variability reveals a change in the orientation of cineole and α-terpineol biosynthesis under the control of climatic factors. This work allows us to discern favorable periods for the harvest of Eucalyptus sideroxylon leaves in terms of yield and quality of essential oils.
