Efeito do Ácido Ascórbico em melões 'Orange Flesh' minimamente processados

The aim of this work was to evaluate the application of different concentrations of ascorbic acid on Orange Flesh melon. Whole Melons were sanifi ed with 500 mg L-1 of sodium hypochlorite for 10 minutes and the cuts into cubes with 100 mg L-1 for 1 minute before being tested under different concentrations of ascorbic acid (0, 1, 2 and 3%) in immersion at room temperature for 10 minutes. After drainage, the cuts were packed in PET packages lined with polyethylene fi lm of 18 µm and stored at 5 ± 1°C and 85 ± 5% of RH for 8 days, being evaluated every 2 days. Physicochemical, microbiological and sensorial analyses were performed. The experimental design utilized for the experiment was the completely randomized in factorial scheme. Ten replicates were used for non-destructive analyses and 3 replicates were used for destructive ones. The application of ascorbic acid reduced the loss of mass; the fruits presented a low population of psychrotrophic bacterias, fi lamentous, fungi and yeasts, reduction of soluble solids, pH and fi rmness and, consequently, extended postharvest life of the fruits by 2 days. The appearance, fl avor and taste were also affected. The application of 1% of ascorbic acid was the best treatment for the fresh cuts “Orange Flesh” melons.

Análise de um trocador de calor tipo serpentina de uma planta de hipoclorito de sódio

This study aims to analyze the capacity of a helical coil heat exchanger to reach the requested heat transfer rates by a sodium hypochlorite production process. This heat exchanger was installed in an experimental way in order to reuse a source of low-temperatures water in such a way to become a more economical alternative than the existing cooling tower. Firstly, the concepts related to the theory of heat transfer applicable to the case were introduced. Then, the mapping of the main information about the production process and the technical specification of the current cooling system equipment's was realized. Using the dimensions of the heat exchanger installed today as reference, the calculations for determining the ideal length of the coil to different flows of hot fluid were performed. Finally, it was concluded that the heat exchanger currently employed does not provide heat transfer rates required for the maximum flow rate value supported by the cooling tower

Antimicrobial effect of endodontic solutions used as final irrigants on a dentine biofilm model

Aim To evaluate the residual biovolume of live bacterial cells, the mean biofilm thickness and the substratum coverage found in mixed biofilms treated with different endodontic irrigant solutions. Methodology Twenty-five bovine dentine specimens were infected intraorally using a removable orthodontic device. Five samples were used for each irrigant solution: 2% chlorhexidine, 1% sodium hypochlorite (NaOCl), 10% citric acid, 17% EDTA and distilled water. The solutions were used for 5 min. The samples were stained using the Live/Dead technique and evaluated using a confocal microscope. Differences in the amount of total biovolume (mu m3), number of surviving cells (mu m3), mean biofilm thickness (mu m) and substratum coverage (%) of the treated biofilms were determined using nonparametric statistical tests (P < 0.05). Results Similar values of biovolume total, biovolume of live subpopulations and substratum coverage were found in 2% chlorhexidine, 10% citric acid, 17% EDTA and distilled water-treated biofilms (P > 0.05). The lower values of the studied parameters were found in 1% NaOCl-treated dentine (P < 0.05) with the exception of the mean biofilm height criteria that did not reveal significant differences amongst the irrigant solutions (P > 0.05). Conclusions One per cent sodium hypochlorite was the only irrigant that had a significant effect on biofilm viability and architecture.

Evaluation of experimental cleanser solution of Ricinus communis: effect on soft denture liner properties

Objective: This study evaluated colour stability, hardness and roughness of soft denture liners after immersion in various cleansers. Materials and methods: Thirty specimens (14 mm x 4 mm) of Elite Soft Relining (ES) and Mucopren Soft (MS) were randomly immersed in distilled water at 37 degrees C, sodium hypochlorite 1%, and an experimental Ricinus communis solution (RC) for 7, 15 and 183 continuous days. Results: ANOVA (p < 0.05) and Tukey's test indicated that after T7 (mu =8.79 +/- 7.36); T15 (mu = 4.23 +/- 2.62) and T183 (mu = 8.78 +/- 3.16), MS presented a higher increase in hardness than ES. After T7, MS underwent an increase in roughness (mu = 0.09 +/- 0.80); ES underwent a decrease (mu = -0.08 +/- 0.16). RC caused the smallest variation in roughness. After T15, both materials presented an increase in roughness. After T183, ES (mu = -0.30 +/- 0.48) presented a higher roughness variation than MS (mu = -0.07 +/- 0.32). Hypochlorite caused an increase in roughness (mu = 0.02 +/- 0.19). Conclusion: After all periods ES presented higher colour alteration than MS; highest colour alteration was caused by hypochlorite. Both materials were more stable after immersion in RC.
