| The present study was performed to compare the effects on antioxidant activity and on DNA damage of organic and conventionally produced apples grown under controlled conditions in human peripheral blood lymphocytes. Six healthy volunteers consumed either organically or conventionally grown apples (Golden Delicious, 1000 g) from two neighboring commercial farms in a double-blinded, randomized, cross-over study. The average content of total identified and quantified polyphenols in the organically and conventionally produced apples was 308 and 321 µg/g fresh weight, respectively. No statistically significant differences in the sum of phenolic compounds or in either of the polyphenol classes were found between the agricultural methods. Consumption of neither... |

| Plums contain high levels of hydroxycinnamates (neo-chlorogenic acid, Neo-CGA), anthocyanins (ATH) and ascorbic acid. The drying process influences their phytochemical content and plum cultivars are known to have different phytochemical retention after drying, but little data exists regarding to possible differences between conventional (CONV) and organic (ORG) plums. The aim of this study was to evaluate the phytochemical content in three different CONV and ORG plum cultivars (Jubileum, Reeves and Victoria) after freeze drying (FD), conventional oven drying (OD) and solar drying (SD). The three cultivars responded differently to the methods of drying. Notably, Jubileum decreased its ATH mostly when subjected to OD while its Neo-CGA content was mostly... |

| Explora as conexões entre uma polêmica apreensão de maçãs contaminadas no sul do Brasil, em 1989, e as reações da indústria da maçã às notícias da imprensa sobre o uso do agrotóxico nas plantações brasileiras. A problemática está inserida em análise mais ampla da ideia de toxicidade e de ‘perigo’, que começa a invadir os domínios público e privado quanto ao consumo de alimentos mais sadios e à ‘segurança alimentar’. Afirma que as respostas dos pomicultores ao problema seriam mais bem entendidas com a leitura histórica das interações entre a biologia da macieira, a agroecologia dessa monocultura e estruturas, atores e discursos que envolvem coletivos humanos e não humanos na região produtora de maçãs. |

| Les premiers résultats confirment l’hypothèse qu’entre les pommes bio et PI, des différences conditionnées par le mode de production existent, tant en ce qui concerne le nombre que la fréquence des moisissures et des levures ; ces différences pourraient s’avérer importantes du point de vue nutritionnel et qualitatif. Ainsi, les pommes biologiques ont présenté un plus grand nombre d’endophytes, dont en majeure partie des moisissures. C’est là un fait important dans la mesure où les consommateurs mangent les pommes avec leur peau et que ces fruits sont stockés au frais pendant plusieurs mois. Afin d’en savoir davantage sur les microorganismes trouvés sur la pomme, un protocole PCR a été établi sur la base de la région ITS de l’ADN, afin d’identifier les... |

| Peach production in the Rhône-Alps region is increasingly challenged by mediterranean European regions. A possible regional strategy would consist in the development of qualification signs. A significant part of the peach production is already labelled (CCP, Red Label, Organic). How such labels relate with quality attributes at field level ? Can polyphenols be considered as an asset in a re-qualification process of peach production? To contribute to these issues, we present preliminary results derived from field work in Rhône-Alps. The study was conducted on 12 orchards of yellow peach (cv Spring Lady) in farms. 10 orchards were managed according to the above mentioned specifications while 2 were cultivated without specifications. Farmers practices... |

| In a 3 years lasting field study with the ‘Golden Delicious’ cultivar, we compared fruits of 5 pairs of organic/integrated fruit farms. The orchards were similar in microclimate, soil conditions and planting system. To assess inner fruit quality we investigated at the beginning and at the end of cold storage: (i) standard parameters (firmness, sugar, malic acid., mineral content); (ii) sensorial quality by panel tests; (iii) health related components (23 phenolic compounds, nutritional fibres; vitamins); and (v) fruit «vitality quality» by holistic approaches (crystallisation in copper chloride, self degradation tests, feeding preference tests with laboratory rats). The most significant differences were found in year one of the study, and were by tendency... |

| In general, organic grown apples (Malus x domestica Borkh.) are not treated with chemical fungicides to prevent storage decay and these fruits may suffer up to 30% decay during storage. Preliminary experiments had shown that hot water dipping of apples may be an alternative. To inhibit Gloeosporium rot (Pezicula alba, P. malicortis) water temperature may be of about 50°C and dipping time from 60 sec up to 180 sec. The present investigation was conducted to test different ranges of temperatures and dipping time periods in different apple cultivars over a three year investigation. The objective was to determinate the suitable hot water treatment that prevents decay incidence and maintains fruit quality (firmness, scale symptoms). For the reduction of post... |

| The EU project Hidras (High Quality Disease Resistant Apples for a sustainable agriculture, QLK5-CT-2002-01-01492) aims to identify genetic factors controlling apple fruit quality with the objective of increasing the acceptability of disease resistant apples. At Agroscope Changins-Wädenswil (ACW) we are performing ex-pert panel tests and consumer tests. The consumer inquiry during the public fair BEA 2005, end of April 2005 in Bern, Switzerland, resulted in comprehensive information on consumption trends in apple for dif-ferent age groups. This work is coordinated with partners in Poland and Belgium. All the age groups consid-ered flavour, juiciness and firmness as very important quality criteria for apples. The preference of apples to other fruit such... |
