“…A antocianina é pertencente ao grupo dos flavonóides, sendo importante na alimentação humana, apresentando ação anticarcinogênica, antioxidante e antiviral (Teixeira et al, 2008). Na literatura foram encontrados apenas alguns trabalhos científicos sobre a conservação da inflorescência de couve-flor (Sigrist, 2002;Goldoni et al, 2004;Brackmann et al, 2005;May et al, 2007). A embalagem em filme plástico (polietileno ou PVC) perfurado diminui a perda de água e aumenta a durabilidade do produto devido à redução na respiração (May et al, 2007).…”

A couve-flor tem grande importância econômica, principalmente para pequenos produtores, sendo uma cultura rentável em pequenas áreas. No entanto, é uma hortaliça de difícil conservação pós-colheita à temperatura ambiente devido à transpiração e ao processo respiratório intenso, o que acarreta alteração na coloração da inflorescência. Desta forma o presente trabalho teve por objetivo a caracterização pós-colheita de couve flor das híbridas Snow Mystique e Grafitti armazenadas à temperatura ambiente (20 ± 2°C e 75 % de UR). Foram realizadas avaliações a cada três dias, durante um período de 12 dias de armazenamento. Os parâmetros avaliados foram a porcentagem de perda de massa em relação ao peso fresco; firmeza da haste; sólidos solúveis; pH e acidez titulável. Avaliando os resultados encontrados pode se concluir que a couve flor não deve ser armazenada a 20 ± 2°C e 75% de UR por mais de três dias, tendo em vista que a inflorescência apresenta elevada perda de água por transpiração. Unitermos: armazenamento, Brassica oleracea var. botrytis, qualidade AbstractPostharvest characteristics of two cultivars of cauliflower. The cauliflower has a great economic importance, especially for small producers, and it turns out to be a profitable crop in small areas. However, at postharvest period it is difficult to store it at a given room temperature due to sweating and a heavy breathing process, which leads to a discoloration of the inflorescence. Thus, the current study aimed to characterize the postharvest storage of cauliflower hybrids Snow Mystique and Graffiti kept at room temperature corresponding to an air temperature of 20 ± 2 o C and a relative humidity (RH) of 75%. Evaluations were made every three days during a period of 12 days of storage. The parameters studied were percentage of weight loss in fresh weight terms, firmness of stem, soluble solids, pH and measurable acidity. By evaluating the results, it was concluded that the cauliflower is not supposed to be stored at an air temperature of 20 ± 2 o C and a 75% RH for more than three days, since the inflorescence presented a high water loss through the transpiration process under the environmental conditions in study.

Periodic use of chemical pesticides in conventional farming systems can lead to environmental degradation. Organic product are believed to be potential for human health. This research was conducted for 144 hours to determine the effect of cultivation and storage methods on the chemical-physical, and organoleptic characteristics of celery during the post-harvest period. This study used a Factorial Randomized Block Design which was repeated three times with the first factor is the cultivation method which consisted of two levels, namely, organic and conventional. The second factor was the storage method which consisted of four levels, namely, stored in the refrigerator with wrapped in LDPE Bag, stored in the refrigerator without wrapping in LDPE Bag, stored in a room temperature wrapping in LDPE bag, and stored in a room temperature without wrapping in LDPE bag. Data obtained were analysed by analysis of variance and then continued with the 5% HSD Test. The results of weight loss showed that the best treatment was obtained in organic cultivation with the scores 48.03% and stored in the room temperature with LDPE bags with the scores 18,31%, and the organoleptic scores were colour 4.13, and freshness value 4.17.
