Cristalização de melão pelo processo lento de açucaramento

The experiment was carried out in the Food Technology Laboratory of the Escola Superior de Agricultura de Mossoro (ESAM), Mossoro-RN, Brazil to evaluate the possibility of processing the melon pulp as a crystallized fruit by using the us following melon varieties: Galia, Pele de Sapo, and Orange Flesh, utilizing the slow sugary process. The pulps were withdrawn in little ball form and put successively into sucrose solutions at 20, 30, 40, 50, 60 and 70°Brix, until boiling, keeping them in inactivity for 24 hours in each solution. After that, the fruits were placed in a stove at 50°C during 6 hours, reaching final humidity between 26.16 and 27.53%. Evaluations for humidity content, pH and total soluble solids were made. In addition a sensorial analysis was made. It was observed that the melon crystallization was technically feasible. Pele de Sapo melon was the best in comparison to the other types. Changing in the melon pulp colouring was not observed.

Changes in chlorophyll, anthocyanins and phenolic compounds concentration in fresh-cut onion

The minimal processing of onion is practical and convenient to consumers, eliminating the inconvenience of peeling, cutting, unwanted odour and tearing effect. The study aimed to estimate the levels of chlorophyll, anthocyanins and phenolic compounds in fresh-cut onions, triturated in the form. Onions, white and purple, obtained in Pombal-PB were conducted in the Laboratory of Food Analysis, Federal University of Campina Grande, Campus Pombal and subjected to minimal processing: selection, removal of external catophilos, sanitising and rinsing, 10 minutes, with 200 and 5 mg.L–1 free chlorine (Sumaveg®), respectively; drain up to 60 minutes, placing in pot of polystyrene (PS 6, 100 mL) with lid, and stored at 4 ± 0.5°C under 65 ± 5% RH for eight days. Overall, there was a reduction in chlorophyll content in onions during storage, especially in purple. The anthocyanin content decreased about 30% during storage in the purple onion. Levels of phenolics increased until day 2 of testing, thereby reducing days until end of analysis.

SAT0501 Early versus late-onset systemic sclerosis: are there clinical and immunological differences?

Background The clinical course of Systemic Sclerosis (SSc) depends on subtype, organ involvement and age. Peak age at onset of SSc is between 30 and 50 years, although SSc may also start in both young and elderly patients. Few data have been reported on patients suffering from late-onset SSc. Objectives To characterise clinical and immunological features of early and late-onset SSc in a tertiary referral hospital. Methods We analysed data from 178 patients followed at our SSc clinic. All the patients fulfilled the ACR/EULAR 2013 classification criteria for SSc or the LeRoy’s criteria for the classification of early SSc. Based on the mean of age of onset of the whole series (50±15 years), ages extremes were defined as younger than 35 versus older than 65 years of age at onset. Disease characteristics as well as clinical and immunological features were evaluated. Results The early and the late-onset groups included 35 and 31 patients, respectively. Patients’ current mean age was 42.8±14.1 vs. 75.8±6.2 with a mean disease duration of 14.5±14.7 vs. 4.3±4.6 years. The most common first manifestation of disease was Raynaud phenomena followed by arthritis/inflammatory arthralgia, in both groups. However, the time between clinical onset and SSc diagnosis was higher in the late-onset group (p=0.034). A higher number of diffuse and pre-SS was observed in the early group but this difference didn’t prove statistically significant. There was a higher prevalence of centromere antibodies in the late-onset group (p=0.001). Clinical manifestations and target-organ damage didn’t differ between groups, except for a higher prevalence of heart conduction abnormalities in the late-onset group (p=0.02). In multivariate analyses, age alone (OR=1.04; 95% CI 1.0, 1.1), but not disease duration (OR=0.99; 95% CI 0.9–1.0), was an independent predictor for the presence of heart conduction abnormalities.Abstract SAT0501 – Table 1 Demographic, clinical and immunological features of Early and Late-Onset SSc Patients. Abbreviations: yr = years; SSc = Systemic Sclerosis. * confirmed by esophageal manometry. ** Based on pulmonary function tests with diffusing capacity of lung for carbon monoxide. *** Diagnosed with echocardiography and confirmed by right heart catheterization wherever available. Conclusions In line with findings from other studies, late-onset SSc shows a distinct clinical and immunological presentation. The present study confirms that late-onset is associated with longer diagnostic delay, positive centromere and heart conduction abnormalities. These observations may be due to age and potential age-associated confounders, rather than the disease itself. Knowledge of these different characteristics can help to improve the management of the disease. References [1] Alba M, et al. Early-versus Late-Onset Systemic Sclerosis. Medicine2014;93(2):73–81.
