“…Almost all the Musa analyzed (except dessert bananas) were found to have β-carotene levels greater than 121 μg·100 g -1 of edible portion, which is at least 5 to 29 times the b-carotene level (21 μg·100 g -1 ) found in bananas analyzed in the United States and the United Kingdom; although those bananas were not documented by cultivar name, they were most likely Cavendish, the primary banana cultivar marketed globally [26,27]. Also, some unripe plantain cultivars have greater amounts of β-carotene (700-1200 μg·100 g -1 of edible portion) compared with some papaya cultivars (80-410 μg·100 g -1 ) and passion fruits (500-1000 μg·100 g -1 ) [1,[28][29][30]. However, green leafy vegetables have very rich β-and α-carotene contents, but they have been shown to have poor bioavailability in relation to orange-fleshed fruits [31].…”

“…The levels of β-and α-carotenes, as well as of lutein, which were low in unripe pulps and then greatly increased in the ripe fruit, reflect the degradation of chlorophylls with a concomitant rise in carotenoids [28]. In addition, according to some studies, soil fertilization, which was applied in the experimental plot during the fruit production cycle, could be one of the factors that affected carotenoid biosynthesis in fruits [34].…”

--Introduction. Bananas and plantains (Musa spp.) are staple foods in Cameroon and surrounding countries. Strategies based on the utilization of cultural and locally consumed foods are essential for the identification of solutions for the reduction of micronutrient malnutrition. Materials and methods. To assess the nutritional content of some varieties in order to assist the selection of new Musa hybrids, the carotenoid contents of 19 Musa cultivars and hybrids from the CARBAP (Douala, Cameroon) germplasm were determined at three ripening stages. Frozen pulps were analyzed for their β-carotene, α-carotene and lutein contents using the HPLC method. The retinol activity equivalents (RAE)·100 g -1 fresh weight were calculated for four representative Musa types. Results and discussion. Significant differences were observed between Musa cultivars according to their genotype. Plantain type (Mbouroukou n°1) and Musa hybrid (CRBP 755) exhibited the highest levels of RAE [(148 and 70) RAE·100 g -1 ] compared with dessert bananas (16 RAE·100 g -1 ). During ripening, the concentrations of these carotenoids increased or decreased significantly (α = 0.05%) according to the Musa type analyzed. The high β-and α-carotene as well as lutein contents of these Musa sp. could contribute to the nutritional status of people consuming these banana varieties in West and Central Africa and enhance their use in Musa breeding programs.

“…A Figura 2 ilustra as equações quadrá-ticas e cúbicas relativas à variação de pH em função do tempo de armazenamento. Alves et al (1995) encontraram valores de pH na faixa de 3,5 a 4,5 em acerolas estocadas a 8 ºC enquanto nos ensaios de Carvalho (1992), para o mesmo fruto armazenado sob refrigeração durante 3 dias, os valores deste parâmetro se situaram entre 3,36 a 3,49. Musser et al (2004) encontraram valores médios na faixa de 3,1 a 3,4, comparando acerolas maduras em diferentes safras do ano.…”

“…De acordo com as funções quadráticas e cúbicas (Figura 3), ocorreu elevação dos valores no início e decréscimo no final do período de armazenamento, comportamento este também encontrado por Maciel et al (2004) em acerolas cobertas com biofilme de fécula de mandioca, armazenadas sob refrigeração. Alves et al (1995) fazem referência a uma variação de 0,87 a 1,26 % de ácido málico nos teores de ATT em acerolas armazenadas a 8°C. A acidez é um importante parâmetro de avaliação da qualidade de frutos tendo em vista que ácidos orgânicos são componentes essenciais do ciclo dos ácidos tricarboxílicos como também do sabor e aroma característicos do fruto (Kays, 1991 Os teores de SST estão representados, graficamente, por equações quadráticas e cúbicas (Figura 4), cujo comportamento ilustra um aumento gradual durante o período de armazenamento.…”

“…Dependendo da natureza do produto, seu armazenamento pode ser conduzido em temperatura de 8 a 10 °C e UR entre 85 e 90%, condições em que se consegue obter prolongamento da vida útil de produtos sem aparente murchamento, enrugamento ou desenvolvimento de doenças pós-colheita (Alves et al, 1995;Finger & Vieira, 2002). A respiração e a produção de etileno em taxas elevadas, reduzem o período de conservação que, no entanto, em frutos climatéricos favorecem o desenvolvimento da qualidade sensorial ideal para o consumo (Finger & Vieira, 2002).…”

O objetivo deste trabalho foi estudar as modificações pós-colheita em frutos de 16 genótipos de aceroleira cultivados no Banco Ativo de Germoplasma/UFRPE, avaliando-se o efeito da refrigeração sobre as características físico-químicas e sensoriais, a fim de determinar o tempo de vida útil. Perda de massa, teor de sólidos solúveis totais (SST), acidez total (AT), pH, ácido ascórbico (AA) e características sensoriais, foram avaliados durante o armazenamento, a 8 °C. Perda de massa e falta de brilho na coloração constituiram fatores determinantes para o descarte dos frutos em relação ao consumo in natura. A refrigeração estendeu a vida útil dos frutos dos genótipos 28, 29 e 43 durante 11 dias e os do genótipo 15, até 15 dias; entretanto, o teor de ácido ascórbico do genótipo 43 e os teores de AA e SST do genótipo 15 não atingiram os valores mínimos exigidos pela indústria e pelo mercado externo. Os genótipos 05 e 39 apresentaram os teores mais elevados de AA (3.017,1 e 2.266,66 mg 100 g -1 de polpa) respectivamente, considerados, portanto, promissores para esta característica. O genótipo 06 indicou teores de SST e AA dentro das exigências da indústria e do mercado externo, com vida útil de até 11 dias apresentando-se, sem dúvida, como genótipo promissor. Palavras-chave:Malpighia emarginata DC., armazenagem, acerola, ácido ascórbico, sólidos solúveis totais Postharvest modifications in fruits from 16 genotypes of west indian cherry stored under refrigeration A B S T R A C TThis work had as objective to study post-harvest modifications in fruits from 16 genotypes of west indian cherry (Malpighia emarginata) cultivated in the Germoplasm Active Bank/UFRPE, evaluating the effect of refrigeration on physico-chemical and sensorial characteristics, in order to determine shelf life. Weight loss, total soluble solids (TSS), total acidity (TA), pH, ascorbic acid (AA) and sensorial characteristics were evaluated during storage at 8 °C. Weight loss and the lack of brightness were limiting factors to discard the fruits in relation to in natura consumption. Refrigeration extended up to 11 days the fruits shelf life of genotypes 28, 29 and 43, and those from genotype 15 up to 15 days, therefore, the ascorbic acid levels of genotype 43 and the AA and TSS levels of genotype 15 did not reach the minimum values requested for industry and exportation. The genotypes 05 and 39 showed the highest AA level (3,017.1 and 2,266.66 mg 100 g -1 of pulp, respectively), being considered promissing for this characteristic. The genotype 06 showed TSS and AA levels inside exportation and industry requirements, reaching up to 11 days shelf life, being also a promissing genotype
