The Use of Headspace Solid-Phase Microextraction (HS-SPME) to Assess the Quality and Stability of Fruit Products: An Example Using Red Mombin Pulp (Spondias purpurea L.)

The present study aimed to evaluate the volatiles profile of red mombin (Spondias purpurea) pulp and its powder produced by spray-drying (SD) as an example to show utility of headspace solid-phase microextraction (HS-SPME) in the analysis of parameters such as the quality and stability of fruit products. Volatiles profiles of the pulp were identified by gas chromatography-mass spectrometry (GC-MS), quantified by gas chromatography-flame ionization detector (GC-FID) and compared to the profile of the powder stored at 0, 60 and 120 days in plastic (PP) or laminated packages (LP). The results showed that the technique was able to identify 36 compounds in the red mombin pulp, 17 out of which have been described for the first time in this fruit, showing that red mombin fresh pulp appears to be unique in terms of volatiles composition. However, only 24 compounds were detected in the powder. This decrease is highly correlated (r(2) = 0.99), at least for the majority of compounds, to the degree of volatility of compounds. Furthermore, the powder stored in PP or LP showed no statistical differences in the amounts of its components for a period of 120 days of storage. Finally, this work shows how HS-SPME analysis can be a valuable tool to assess the quality and stability of fruit products.

EFFECTS OF EMERGENCY IN BIOSTIMULANT SEEDLING OF PASSION FRUIT ROXINHO OF KENYA

The increase in market demand for fresh fruits along with the high price of passion fruit juice in domestic and international markets has increased the interest in fruit, especially the purple passion fruit in the center south of the country seeking to export. This study aimed to evaluate the effects of plant growth regulator on the emergence and development of seedlings of passion 'Roxinho of Kenya' when propagated sexually. The treatments consisted of concentrations of commercial product Stimulate (R): control (no biostimulant); 6; 12; 18; 24 and 30 mL. kg(-1) of seed. It were evaluated the percentage of seedling emergence, number of leaves, aerial part dry weight, stem and root (g), root length (mm), diameter and stem length (mm), leaf area and chlorophyll 'a' and 'b'. The application of bio-stimulant in doses of 6 and 12 mL. kg(-1) promotes increased percentage of seedling emergence of Passiflora edulis Sims in a shorter time. The use of it also promotes the development of seedlings, with better results for the dose of 12 and 24 mL. kg(-1) treated seeds.

Atividade antibacteriana de plantas do cerrado da região de Botucatu - São Paulo

The studies related to research on new antimicrobial products have received special attention from researchers, especially given the emergence of microbial strains resistant to conventional antimicrobials. Thus, the present study was aimed to test the antimicrobial action of hydro-alcoholic extracts of plants collected in Cerrado region of Botucatu, following the species: Achyrocline satureioides (Lam) DC (macela), Stryphnodendron adstringens (Mart) Coville (barbatimão), Miconia rubiginosa (Bonpl.) DC (quaresma-branca), Davilla elliptica A. St-Hil (lixinha), Siparuna guianensis (negramina) e Solanum lycocarpum A.St-Hil (lobeira). The plants were always collected in the morning, in areas near the town of Botucatu, and extracts were prepared using a solvent such as methanol 70% from materials dried (50°C) and ground into mill knives. The extraction was performed for 48 hours at refrigerator temperature, followed by filtration, removal of methanol solvent in a rotary evaporator, determination of the dry weight of the extracts (mg / mL) and phytochemical analysis of the same. The sensitivity tests for 10 S. aureus, 11 E. coli and 11 P. aeruginosa, isolated from human clinical cases were performed by diluting volumes of the extracts in Mueller Hinton Agar (MHA) and determination of minimum inhibitory concentration (MIC) (mg / mL). According to the results and statistical analysis, it was found that depending on the bacteria tested, and in descending order of antibacterial activity for S. aureus: Lixinha sheet > Barbatimão sheet > Quaresma-Branca > Macela > Lixinha fruit > Barbatimão shell > Lobeira > Negramina; E. coli: Lixinha sheet > Barbatimão sheet > Lixinha fruit = barbatimão peel > Quaresma-Branca > Macela = Lobeira > Negramina and P. aeruginosa: Lixinha leaf > Barbatimão bark > Barbatimão leaf > Lixinha fruit > Macela > Lobeira > Quaresma - Branca = Negramina...

A Solid Film Electrode of Intermetallic Ag 2 Hg 3.02 for the Direct Determination of Folic Acid in Fresh and Processed Fruit Juices

AgSIE was used for the direct analysis of folic acid (FA), with a detection limit and lower level of quantitation of 6.8 x10-10 mol L-1 and 2.3 x 10 8 mol L-1. The analysis in fresh and processed fruits was done without any sample pretreatment. In strawberry and acerola juices, FA concentration level values were below the method detection limit. FA was detectable in peach (77.7 0.4 mg L-1 and 64.4 0.5 mgL-1), Persian lime (45.4 0.7 mg L-1), pineapple Hawaii (66.2 0.4 mgL-1), pear pineapple (35.3 0.6 mgL-1), cashew (54.4 0.5 mgL-1) , passion fruit (73.2 0.3 mgL-1), and apple (84.4 0.5 mg L-1 ).

Parâmetros termodinâmicos da casca de laranja desidratada

The global energy scenario is currently a widely discussed topic, with growing concern about the future supplies. Thus, much attention has been dedicated to the utilization of biomass as an energy resource. In this respect, orange peel has become a material of great interest, especially to Brazil, which generates around 9.5 million tons of this waste per year. To this end, the authors studied the kinetics of the thermal processing of dried orange peel in inert and oxidizing atmosphere. The thermodynamic parameters were determined by the Ozawa-Flynn-Wall method for the global process observed during heating from the 25 degrees C up to 800 degrees C. The thermal analysis in air and nitrogen showed 3-2 stages of mass loss, respectively, with approximately 20% residual mass under a nitrogen atmosphere. The increase in the values of activation energy for the conversion points between 20% and 60% for thermal effects in air and nitrogen atmosphere was observed. The activation energy obtained in an oxidizing atmosphere was higher than that obtained under a nitrogen atmosphere. The fourier-transform infrared spectroscopy and X-ray diffraction analysis showed that the material has a high level of complexity with the presence of alkali and alkaline earth groups as well as phosphate, plus substances such as pectin, cellulose and lignin.
