Post-harvest of parsley leaves (Petroselinum crispum): Mathematical modelling of drying and sorption processes AGRIAMBI
Corrêa Filho,Luiz C.; Martinazzo,Ana P.; Teodoro,Carlos E. de S.; Andrade,Ednilton T. de.
ABSTRACT Parsley is a species of wide production and trade in Brazil due to its high consumption as a condiment, fresh or dried. In the development of equipment used for drying, it is important to simulate and obtain theoretical information about the behavior of water loss for each product. Given the increasing use and potential commercialization of condimental plants, the objective of this work was to determine the isosteric heat of parsley leaves and fit mathematical models to the experimental data obtained in drying and desorption processes. The modified GAB and Midilli models were the most appropriate to describe the desorption isotherms and drying curves, respectively, for the studied temperatures. The isosteric heat varied from 3394.6 to 2830.0 kJ...

Essential oil production of lemongrass (Cymbopogon citratus) under organic compost containing sewage sludge AGRIAMBI
d'Ávila,Júlia V.; Martinazzo,Ana P.; Santos,Fabiana S. dos; Teodoro,Carlos E. de S.; Portz,Adriano.
ABSTRACT One of the main urban polluting agents are the sewers, which even with proper treatment end up generating a polluting waste, the sewage sludge. One of the options for the disposal of this sludge is the use in agriculture, due to its high content of organic matter and nutrients. This study aimed to use urban sewage sludge for lemongrass cultivation and essential oil production. The plants were grown in soil containing different organic compost doses (0, 5, 10, 20, 40 and 60 t ha-1), formed from the sewage sludge composting process and waste of urban vegetation pruning. At harvest, plants were analyzed for the concentration of nutrients, chlorophyll content, number of tillers, biomass production, essential oil content and the microbiological quality...
