“…Some early investigators reported that ascorbic acid content increased in the immediate postharvest period and then gradually declined. For example, Carnelossi et al (2009) reported an increase in vitamin C content in mangaba fruits after 2 days of storage at 24°C, followed by a sharp fall.…”

The objective of this study was to determine vitamin C stability in fresh and freeze-dried capsicum during storage at different temperatures. Fresh capsicum stored at 20°C showed an initial decrease in vitamin C with a minimum peak after 2 days and then increased to a maximum peak after 13 days followed by a gradual decay. In general a gradual decrease of vitamin C was observed in the cases of fresh (i.e. stored at 5, −20, −40°C) and freeze-dried capsicum stored at all temperatures (i.e. 60 to −40°C). The degradation kinetics of vitamin C was modeled by zero and first order reaction and rate constants were estimated. The rate constant increased with the increase in storage temperature, while it was decreased with the decrease of moisture content. At storage temperature 5°C, first order rate constants were observed as 7.1×10 −2 , 7.7×10 −2 , and 4.3×10 −3 day −1 in the cases of samples containing moisture contents 94, 15 and 5 g/100 g sample, respectively.

resumo -A mangabeira (Hancornia speciosa Gomes) é uma árvore nativa do Brasil, cujo fruto é obtido predominantemente de forma extrativista e apreciado tanto in natura quanto na forma de polpas, geleias, doces. As raízes, cascas e látex possuem uso medicinal e sua madeira é usada como combustível. Ocorre do Nordeste até os Cerrados das regiões Centro-Oeste, Norte e Sudeste. Entende-se que estudos científicos sobre espécies nativas de base extrativista são essenciais a fim de subsidiar estratégias para a conservação da espécie. O presente trabalho objetivou analisar as publicações acadêmicas sobre a mangabeira disponíveis na plataforma de periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), utilizando os princípios da bibliometria. As buscas aconteceram por meio das palavras chave: "mangaba", "mangabeira" e "Hancornia speciosa Gomes", o que resultou em 103 publicações sobre a espécie. Essas publicações foram classificadas de acordo com o ano, o tipo e o periódico de publicação; e, de acordo com o seu conteúdo, enquadradas nas áreas de conhecimento estabelecidas pela Capes. Após o enquadramento verificou-se que 40,8% das pesquisas estão relacionadas às Ciências Biológicas, 19,4% às Ciências de Alimentos, 13,6% às Ciências Agrárias, 10,7% às Ciências da Saúde, 7,8% às Ciências Multidisciplinares e 1,9% às Ciências Sociais Aplicadas. Constatou-se que há poucos estudos sobre aspectos socioeconômicos, ecológicos e culturais, o que indica a necessidade de mais estudos sob esses enfoques para subsidiar estratégias para a conservação da espécie.

Is the Northeast to the Cerrado of the Center-West, North e East of the country. It is understood that scientific studies of native species of extractive base are essential in order to support strategies for the conservation of the species.

“…Lee and Kader (2000) reported that, although the ascorbic acid content decreases with maturation, there may be an increasing trend due to the increase in the total volume of juice with advancing maturation process. This increase can be analyzed at the twentieth day of storage, but it is also the result of oxidative reactions that vitamin C undergoes during ripening by acting as a molecule with antioxidant properties (Carnelossi et al, 2009). Ascorbic acid has characteristics of unstable molecule that may undergo auto-oxidation into dehydroascorbic acid, which although being reversible, may cause losses in product quality (Gonçalves and Maia Campos, 2009) and lead to increased and decreased contents in stored fruits.…”

Cagaita fruits are subject to seasonality and perishability. This work aims to use scanning electron microscopy (SEM) to evaluate the physicochemical characteristics, texture, color and physical structure of cagaita fruits coated with different chitosan concentrations. The fruits were divided as follows: T0 (uncoated fruits), T1 (fruits coated with 1% (v/v) chitosan), T2 (fruits coated with 2% (v/v) chitosan) and T3 (fruits coated with 3% (v/v) chitosan). They were analyzed at 0, 10, 20 and 30 days of storage. Titratable acidity and soluble solids content showed no conservation of fruit characteristics; they showed better results for uncoated fruits, as well as weight loss, vitamin C and peak strain. The color of cagaita fruits confirmed ripening during storage regardless of treatment. Scanning electron microscopy showed that the film solution did not adhere, as desired, to the cell wall of fruits. As the results of fruits coated with 3% pectin were close to control, further studies should be carried out with higher coating percentages so that the fruit quality is maintained during storage.
