Eficácia de produtos químicos no controle do fungo manchador botryodiplodia theobromae em madeira de hevea brasiliensis

In Brazil, the exploration and use of the Hevea brasiliensis Mull Arg. wood at the end of the latex production cycle from 30 to 35 years, is practically unknown. However, one of the most significant problems with its use relates to the high susceptibility of this species wood to the fungus Botryodiplodia theobromae attack, especially during the primary wood processing phase. The present study evaluated the efficacy of four chemicals to control juvenile and adult Hevea brasiliensis wood from the attack of the fungus stainer Botryodiplodia theobromae following the ASTM 4445 (2003) standard. The results showed that the active ingredients separately tested and evaluated in the laboratory; (Quinolinolato Copper - 8 and Carbendazim (T1); Tribromofenol 2-4-6 (T2); Extract-Based Vegetable Tannin (T3); Carbendazim and Prochloraz (T4)) do not totally prevent the contamination of Botryodiplodia theobromae in 5% level of significance

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.

Avaliação microbiológica e sensorial do guacamole conservado pelo frio

Avocado (Persea americana Mill.) is a product grown in tropical and subtropical regions and from it we can extract products like guacamole which is highly consumed in the Mexican culinary. The most used varieties for guacamole are the Hass and Fuerte. The present research had as objective to evaluate the microbiological and sensorial quality of the guacamole conserved through cold with no addition of additives. The microbiological analyses have shown the product reached satisfactory results as for the analysis of total and thermoenduring coliform < 3,0 UFC/g, Salmonella absent in 25g, Staphylococcus aureus and Bacillus cereus < 100 UFC/g, presenting values within the patterns set by RDC of Anvisa 12 of January 2nd 2001. The analyses of mesophile bacteria and the counting of mold and yeast reached values between 102 and 104 UFC/g and the psychrotropic bactéria presented values < 100 UFC/g. The sensorial anlyses have shown that the polyethylene package isn't effective in keeping the analysed sensorial parameters. Although the polyethylene and nylon packages had better results, however they didn't differentiate themselves so as the vacuum use.

Avaliação nutricional e conformidade da rotulagem de “petiscos” consumidos por crianças à legislação brasileira

Label is every and any information regarding to a product that is transcribed in its package. For the consumer it is through the nutritional information tables contained in the labels that there is access to data such as quantity and percentage of nutrients contained in foods. Through this knowledge, it is possible to make healthier food choices, minimizing the negative effects related to poor nutrition in the population, especially among children, the most critical rate of obesity incidence. The aim of this study was to evaluate the appropriateness of the labels of some foods consumed by children in relation to the Recommended Daily Intake (RDI) and verify that the general aspects of the labels were in accordance with Brazilian regulations. Five products were selected like snacks, corn snacks, snacks, peanut, peanuts, potato snacks and biscuit recipes. The labels of different brands of each snack were analyzed using the Checklist of Labelling, which is based on RDC No. 259 and RDC No. 360. The nutritional adequacy of nutrients from these foods (carbohydrates, protein, total fat, saturated fat, trans fat, dietary fiber and sodium) was evaluated in relation to that recommended by the RDA for children 4-8 years old. There was small percentage of mistakes in the labels of the analyzed foods, about 12%, being the presence of words that induce the consumers to the misunderstanding the irregularity with larger predominance, present in 25% of the labels. Other items in disagreement were the incomplete specification of the addictive ones alimentary in the list of ingredients and the absence of instructions about the conservation of the foods after opening the packings, both with percentile of occurrence of 18,75%. The high sodium content found in the nutritional information of food shows that should reduce the consumption of these products among children.

Desempenho mecânico de embalagens rígidas utilizadas na indústria agroquímica: estudo de compressão

The world population is growing at exponential scales, thus the demand for food grows significantly. The use of pesticides is seen as a way to meet the demand for food and increase the efficiency and productivity of the agricultural sector. BASF SA in partnership with packaging suppliers represent a remarkable scene in the Brazilian market in the agrochemicals sector. In 2014, the Department of Agro from BASF Packaging, identified in its production process certain deformation of its rigid packaging during the filling process of pesticides. This phenomenon is probably caused by the low resistance to compression that the package is used. In order to eliminate the deformation of rigid packaging arising from the filling step, a study will be conducted in conjunction with the supplier JET UNIPAC whose on line problems occurred more frequently. The study is to identify the strength of the rigid containers standardize a compression resistance value at which the package is not deformed after the filling step. This study will present an investigation through experiments combined with theoretical concepts in order to determine possible causes for the emergence of this phenomenon. At the end of the study, a solution to eliminate or reduce to the maximum the packaging deformation problem appears
