“…The ascorbic acid content (Table 2) ranged from 182.84 to 336.69 mg 100 g -1 , being higher han those reported by Sancho et al (2007) and Silva et al (2012) and partially similar the freshly processed pulps evaluated by Figueiredo et al (2007). There was variation in the ascorbic acid contents of cashew pulps, with reduction in three of the four batches evaluated, mainly from the second to the third processing stage.…”

This study aimed to evaluate the nutritional characteristics, bioactive compounds and microbiological quality during the processing and frozen storage of cashew pulps. Cashew pulps from 4 batches and 3 different sequential stages of industrial processing and storage (after pulping, after pulp thawing that was stored for 3 months in a drum, and 90 days after packaging in bugs and frozen storage at-20 °C) were obtained and submitted to the following analysesI: pH, total soluble solids (TSS), color (L*, c* and H°), acidity, ascorbic acid, glucose reducing sugars, total phenols, antioxidant potential by reducing DPPH (1,1-diphenyl-2-picrylhydrazyl) and microbiological parameters (Fungi, psychrotrophic bacteria and coliforms). There was interaction between batches and processing steps for all evaluated parameters, except phenols in acetone extract. The acidity of all batches verified was below of the minimum value recommended by current legislation. Sugars, acidity, ascorbic acid and color were negatively affected during processing. The phenolic compounds presented slight modifications, with a slight increase between the first two stages. Although the antioxidant potential presented variations, there was no single response profile for all batches. High microbial counts were observed after pulping, however there were considerable reductions throughout the processing/storage.

“…Feitosa et al (1997), avaliaram o perfil microbiológico de polpas de acerolas congeladas dos estados do Ceará e Rio Grande do Norte, obtendo contagens de coliformes a totais e termotolerantes < 3NMP/g em todas as amostras analisadas; e contagens de bolores e leveduras variando entre < 10 a 8,9 x 10 3 UFC/g de polpa. Resultados semelhantes aos obtidos por Silva et al (2012), que analisaram polpas de acerolas pasteurizadas e congeladas do estado do Ceará, obtendo contagens de coliformes totais e termotolerantes < 3NMP/g em todas as amostras analisadas; e contagem de bolores e leveduras de 10 UFC/g. De acordo com o Padrão de Identidade e Qualidade (PIQ) (BRASIL, 2000), as amostras devem apresentar um valor mínimo de 0,80% para acidez total titulável para as polpas de acerola.…”

Acerola or west indian cherry (Malpighia emarginata DC) is a tropical fruit with high economic potential, and nutritional relevance due to its high vitamin C content. The continuous increase on fruits consumption, associated to the improvements on the quality control of foods indicated that the commercialization of frozen tropical fruits pulps should continue to increase, due to its convenience and nutritional appeal. Nevertheless, due to its composition, fruit pulps are a good substrate for the microbial growth, which can deteriorate the product, and cause harm to the human health. Therefore, it is extremely important to evaluate the quality of the commercialized fruit pulps, in order to verify their accordance to the legislation requirements. This work aimed to evaluate the quality of two brands of frozen acerola pulps (A and B) commercialized in the Londrina city, state of Paraná, Brazil. For this purpose, microbiology analysis (moulds and yeasts, total coliforms, and termotolerants counts), and physicochemical analysis (titratable acidity, pH, and total soluble solids) were performed. Analyses were done on five different samples of 5 Kg each. The two brands analyzed were in accordance to the Brazilian legislation requirements in relation to the parameters of quality and identity, and did not present microbiological contamination, which indicated safety in their consumption. DOI: http://dx.doi.org/10.14685/rebrapa.v3i1.65

Resumo O presente estudo teve como objetivo a avaliação dos parâmetros físico-químicos e microbiológicos, e da atividade antioxidante de polpas de frutas produzidas e comercializadas no município de Santarém-PA. Foram analisadas três marcas de polpas congeladas de acerola (Malpighia emarginata), cupuaçu (Theobroma grandiflorum) e maracujá (Passiflora edulis), com a finalidade de verificar a sua adequação às normas e aos Padrões de Identidade e Qualidade (PIQ) estipulados pela legislação brasileira. Os parâmetros analisados foram pH, acidez total titulável, sólidos solúveis totais, sólidos totais, cinzas e ácido ascórbico; buscou-se determinar o teor de polifenóis totais e da atividade antioxidante pelo método de DPPH, e foram realizadas análises microbiológicas para pesquisa de bolores e leveduras, coliformes fecais e Salmonella sp. As médias dos tratamentos foram comparadas pelo teste de Tukey, adotando-se o nível de significância 95%. Os resultados revelaram que apenas o parâmetro pH estava de acordo com a legislação. Após a análise de acidez total titulável e sólidos totais, pôde-se constatar que todas as amostras não atenderam aos valores estabelecidos pela legislação. A análise de polifenóis totais e a atividade antioxidante revelaram que as polpas de acerola se destacaram pelo expressivo teor desses componentes, sendo estas consideradas como boa fonte de substâncias antioxidantes. Já os resultados das análises microbiológicas demonstraram que todas as amostras estavam de acordo com a legislação em vigor. As variações reportadas na maioria das análises mostram a necessidade da padronização dos processos produtivos das polpas.
