The antioxidant and chelating properties of essential oils Syzygium aromaticum L. Origanum vulgare their principal eugenol carvacrol constituents were evaluated by the thiobarbituric acid reactive substance (TBARS) assay in presence iron(II) ions cyclic voltammetry. In TBARS assay, more efficient than butylated hydroxytoluene (BHT) standard. anodic current decreased 99.7% S. oil, 99.8% for eugenol, 89.3% O. vulgare, 99.4% carvacrol. UV spectra contained a band at 390 nm interaction between...
Ethyl carbamate was quantified in cachaça using high-performance liquid chromatography with fluorescence detection during the production process and storage different types of wooden casks glass containers, without presence light. According to physicochemical analysis, head tail fractions are unacceptable for consumption. detected sugarcane juice fermentation. During distillation, ethyl levels ranged from limit 17.1 μg L−1. increased casks. The (or absence) light did not affect formation...
Abstract BACKGROUND Nutritional intervention with the use of phytochemicals is an important method for treatment and prevention a metabolic syndrome. The objective this study was to chemically characterize Moro orange juice. influence juice intake on parameters rats that were obese, diabetic or both by means body mass management after activation anthocyanins during refrigerated storage also assessed. RESULTS Juice reversed most abnormalities exhibited obese rats, including reduction...
Abstract The effective control of an insect pest such as Drosophila suzukii (Diptera: Drosophilidae) has been challenging because its attack on red fruits can cause losses in production up to 80% worldwide. objective this work was extract and characterise the essential oil from rosemary ( Rosmarinus officinalis ), produce nanoparticles incorporated with oil, evaluate vivo insecticide activity free nanoencapsulated against D. , effect that enzyme acetylcholinesterase. produced had a particle...
The possibility of commercialization Moro blood oranges in tropical countries such as Brazil was evaluated to verify whether post-harvest management through storage at low temperatures for a period 60 days can improve the bioactive properties and quality parameters. cultivated did not contain significant amounts anthocyanins time harvesting, but these compounds were activated by (4°C 8°C) days. emergence juices occurred within few weeks storage, maximum levels attained after temperature 8°C....
The present work sought to characterize the cyanogenic glycoside dhurrin in five sugarcane varieties and determine its possible relationship with formation of ethyl carbamate cachaca. For each variety, methanol, acetate hexane extracts were prepared submitted thin layer chromatography. Chromatographic spots revealed iodine vapors. physical chemical parameters spirits produced from different sugar cane by production processes within legal limits. Although not exceeding limit for carbamate, a...
Abstract In addition to pesticidal activity, the capacity of natural compounds inhibit reproduction parasites emerge as an important alternative tick control method. this context, Satureja spp. stand out due their recognized properties. Among veterinary importance, cattle tick, Rhipicephalus microplus , is responsible for great economic losses in livestock and transmission relevant pathogens. Thus, aim study was evaluate effects different concentrations essential oil montana L. on ovary...
ABSTRACT Essential oils can be a useful alternative to the use of synthetic fungicides because they have biological potential and are relatively safe for food agricultural products. The objectives present study were evaluate antifungal antimycotoxigenic activities essential from Satureja montana L., Myristica fragrans H. Cymbopogon flexuosus S. against Aspergillus flavus ochraceus, as well their effects on ergosterol synthesis membrane morphology. was evaluated by mycelial growth analysis...
Abstract The table grape is a non-climateric fruit that very susceptible to fungal contamination, in addition suffering an accelerated loss of quality during storage. vitro and antifungal antiocratoxigenic effects the essential oils from Alpinia speciosa Cymbopogon flexuosus against Aspergillus carbonarius niger were studied. encapsulated poly(lactic acid) (PLA) nanofibers as potential active packaging be applied control degradation grapes stored post-harvest period. Fungal proliferation...
Knowledge of the chemical composition Mozambican spirits is extremely important because studies potentially toxic compounds have been a determinant factor in quality control. The objectives this work were to analyze and physicochemically characterize distilled sugarcane other raw materials from Mozambique on basis standards established by Brazilian Ministry Agriculture, Livestock Food Supply (MAPA). samples came five provinces southern central Mozambique, provided owners stills localities...
