“…However, consumers concerning over pesticide residues on foods, along with pathogen resistance to many currently used pesticides, has increased the need to find alternative methods for decay control. Recently, biologically active natural products are becoming an effective alternative to chemical fungicides (Tripathi and Dubey 2004). So far, packaging, refrigeration, coating and dipping are the most common approaches used for extending the shelf life of mushrooms (Eissa 2007;Mau et al 1993;Roy et al 1993).…”

Freshness of mushrooms (Agaricus bisporus) was related to the internal atmosphere composition during modified atmosphere packaging (MAP) experiments using polyvinyl chloride (PVC) wrap, polyethylene-1 (PE-1) and PE-2 films. The packaged mushrooms were stored at 12°C for 7 days and lightness value, browning index, weight loss and maturity index were also measured. The results obtained showed that the whiteness of whole mushrooms varied significantly with the type of coating (chitosan and CaCl 2 ), but not with the type of packaging films. It was evident that the extent of darkening in whole mushroom was greater than in sliced ones after coated. In addition, mushroom in PE-2 package exhibited the lowest weight loss due to the lower permeability of film. And the type of packaging films significantly affected the maturity index of mushroom, where PE-2 packaging most effectively lowered maturity index for both whole and sliced mushrooms. By considering the overall quality, it was obvious that PE-2 packaging combined with coating treatment was the most effective to improve the preservation of mushrooms stored at 12°C up to 7 days and satisfy consumer acceptance.

“…Due to these unique properties, chitosan and its derivatives have been proposed for applications in biomedical, food, agriculture, biotechnology and pharmaceutical fields (Felse and Panda 1999;Kumar 2000;Shahidi et al 1999). Currently, the natural compounds are the focus of biotechnological companies looking for new antimicrobial agents (Tripathi and Dubey 2004).…”

In the present study, Chitin has been extracted from Podophthalmus vigil. The obtained chitin was transformed into the more useful chitosan we evaluated the antimicrobial activity of different concentrations (25%, 50%, 75% and 100%) of chitosan against 10 species of bacteria and fungi by agar-disc diffusion method. As the concentration of chitosan increased, the antimicrobial effect was strengthened. In the conjugated diene method, the total antioxidant activity of chitosan was ranging from 18.37% to 79.58% at varying concentrations (0.1 to 10mg/ml). The reducing capability ranged from of 0.12% to 0.48% at varying concentration (0.1 to 10mg/ml). The 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging potential of chitosan ranged from 18.08% to 55.56% at varying concentrations (0.1 to 10mg/ml). The chelating ability of chitosan from Podophthalmus vigil on ferrous ions was ranging from 25.82% to 73.54% for the concentration between 0.1-10mg/ml. Hydroxyl radicals scavenging activity of chitosan (0.125-2 mg/ml) was found to be higher than the ascorbic acid and the range was from 23.18% to 93.28%. Superoxide anion radical was ranging from 5.21% to 65.81% for the concentration between 0.125-2 mg/ml. overall, chitosan from Podophthalmus vigil was good in antimicrobial and antioxidant activity, and may be used as a source of antioxidants, as a possible food supplement or ingredient in the pharmaceutical industry. .

Influência da nutrição mineral foliar sobre doenças da parte aérea da cultura do trigo Rev. Ceres, Viçosa, v. 59, n.1, p. 71-76, jan/fev, 2012 RESUMO ABSTRACT Influence of leaf mineral nutrition on wheat diseasesThe use of fungicide for controlling of wheat foliar diseases is a common practice among farmers. However, due to the environmental impact caused by widespread use, some alternative pathogen controls are needed. This work aimed to evaluate the effect of leaf mineral nutrition on the control of wheat foliar diseases, and its effect on the plant. The experiment was arranged in a randomized block design with four replications and four treatments: 1-control; 2-leaf fertilization at 30 days after emergence (DAE) and at 75 DAE; 3-fungicide at 30 and 75 DAE; and 4-leaf fertilization at 30 DAE and foliar fertilizing + fungicide at 75 DAE. Nine incidence evaluations were carried out for powdery mildew to calculate the area under the disease progress curve; three evaluations for rust severity and gluma spots; and two evaluations for yellow spot yield, mass of fresh and dry matter of aerial parts and root system were determined. There was reduction in the intensity of powdery mildew as a function of leaf fertilization, only in the first evaluation of Recebido para publicação em
