Pineapple aroma is characterized by several esters, which confers its fresh and fruity aroma. However, high concentrations of methyl hexanoate and thioesters bring an undesired pungently sweet aroma and sulfurous notes to pineapple juice. This study investigates the chemical effects of cold plasma on the aroma compounds and descriptors of pineapple juice, evaluating the effects of plasma on its esters and thioesters. Dielectric barrier discharge plasma was applied to pineapple juice, varying the excitation frequency (50 to 1000 Hz) and processing time (10 to 20 min) at constant voltage (20 kV). Plasma treatment induced successive demethylation of esters and the conversion of methyl esters into ethyl esters. Thioesters showed to be more stable under plasma treatment. Proper setting of plasma operating conditions enabled an improvement in the fresh and fruity descriptors of pineapple juice, a reduction of its undesired pungently sweet aroma, but an increase in the influence of sulfurous descriptors. Plasma treatment at 50 Hz reduced the undesired aromas of pineapple while maintaining its fresh and fruity descriptors. |

Produção de urucum (Bixa orelana L.) inoculado com fungos micorrízicos em sistemas de policultivo: The urucum seedlings were inoculated with VA-mycorrhizal fungi in the nursery, on non-sterilized substrate. Root colonization in the nursery before planting into the field was statistically higher for inoculated plants (59% + ou - 11%) than for non-inoculated plants (31% + ou - 20%). After some time in the field, root colonization was the same in the different treatment regimes. However, the highest percentage colonization was found in the plants which received only 30% of the recommended fertilizer dose. The plant height in the different treatment regimes did not differ statistically. There was a significant difference in stem diameter between the two fertilization levels, but the stem diameters of the inoculated and non-inoculated plants were the same within each fertilization level. There was no statistical difference in the production of dry seeds/plant in the first year between inoculated and non-inoculated plants at the two fertilization levels. |
