Efeito do cloreto de cálcio na qualidade de abacaxi 'Pérola' minimamente processado
Antoniolli, Lucimara Rogéria;Benedetti, Benedito Carlos;Souza Filho, Men de Sá Moreira de;
Pesquisa Agropecuária Brasileira , 2003, DOI: 10.1590/S0100-204X2003000900012
Abstract: the objective of this research was to evaluate the effects of calcium chloride on quality of fresh-cut 'pérola' pineapple. the experimental design was a completely randomized in a 3x5 factorial scheme, and the treatments were represented by the cacl2 concentration and storage time, each one with three replicates. fruits were sanitized, peeled mechanically, sliced manually and dipped into water (control) and in cacl2 solutions (1% and 2%) for 30 seconds. slices were placed in polyethylene terephtalate packages and stored at 4±1°c during periods of 0, 3, 6, 9 and 12 days. texture was not influenced by any of the studied factors. smaller peroxidase activity in the samples submitted to cacl2 2% was verified. fresh-cut pineapple slices dipped in cacl2 1% showed more browning, presenting smaller l* value and larger a* value at the end of the storage period. the use of cacl2 in fresh-cut 'pérola' pineapple does not provide beneficial effects on the texture and interfere negatively on the flesh color of fruit.
Efeito do cloreto de cálcio na qualidade de abacaxi 'Pérola' minimamente processado

Abstract: O objetivo deste trabalho foi avaliar os efeitos do cloreto de cálcio na qualidade do abacaxi 'Pérola' minimamente processado. Os tratamentos, arranjados em delineamento inteiramente casualizado e dispostos em esquema fatorial 3x5, consistiram das concentra es de CaCl2 e dos períodos de armazenamento, com três repeti es. Frutos previamente sanitizados foram descascados mecanicamente, fatiados manualmente e imersos em solu o de CaCl2 a 1% e a 2% e em água (controle), durante 30 segundos. As fatias foram acondicionadas em embalagens de polietileno tereftalato e mantidas à temperatura de 4±1degreesC durante períodos de 0, 3, 6, 9 e 12 dias. A textura n o foi influenciada por nenhum dos fatores estudados. Constatou-se menor atividade peroxidásica nos frutos tratados com CaCl2 2%. Quanto à colora o, a imers o em solu o de CaCl2 1% resultou em fatias mais escurecidas, com menor valor L* e maior valor a* ao final do período de armazenamento. A utiliza o de CaCl2 em abacaxi 'Pérola' minimamente processado n o proporciona efeitos benéficos na textura, e interfere negativamente na colora o da polpa do fruto.
Avalia??o da vanilina como agente antimicrobiano em abacaxi 'Pérola' minimamente processado
Antoniolli, Lucimara Rogéria;Benedetti, Benedito Carlos;Souza Filho, Men de Sá Moreira de;Borges, Maria de Fátima;

Abstract: the purpose of this research was to evaluate the effects of vanillin as an antimicrobial agent, as well as the relationship between the injury degree and initial contamination in fresh-cut pineapple (ananas comosus (l.) meer) cv. pérola. slices and cubes were obtained from whole fruits that were mechanically peeled and sliced after sanitization. both kinds of cutting were dipped in pure water (control) or vanillin solutions 3000 or 5000mg.l-1, for 30 seconds. after that, the liquid was drained, slices and cubes were placed in polyethylene terephtalate packages and stored at 4 ± 1°c during 12 days. microbiological analyses were carried out every 3 days and involved mesophile aerobic counts, molds and yeasts and total and fecal coliforms determination. the use of vanillin was inefficient for the control of mesophile aerobic and molds and yeasts growth on fresh-cut 'pérola' pineapple. it seems that, the greater degree of injuries made in the cubes had favored the initial contamination of the product.
Influência da posi??o e formato de corte na preferência sensorial de abacaxi 'Pérola' minimamente processado
Antoniolli, Lucimara Rogéria;Benedetti, Benedito Carlos;Souza Filho, Men de Sá Moreira de;Garruti, Deborah dos Santos;
Revista Brasileira de Fruticultura , 2005, DOI: 10.1590/S0100-29452005000300041
Abstract: the purpose of this research was to determine the best portion of pineapple fruit to be used as fresh-cut considering soluble solids (ss), titratable acidity (ta) content and preference, as well as the preferred cut shape for its commercialization. fruits were manually peeled, delimited in 12 sections of 1cm and sliced. each slice was evaluated for the ss and ta content. the experimental design was in randomized blocks. the studied factor was the fruit section, with four replicates. the data were submitted to the variance analysis and compared by tukey's test. the preferred fruit portion was evaluated by "ranking preference" test, and the results were analyzed by friedman's test. fruits were also evaluated for cut shape by "paired preference" test. considering the ss and ta values no restrictions were found for the total use of the fruit, however the portion delimited by the apical 3 cm was little accepted, suggesting that the portion between the 4th and 12th sections should be used in the minimum processing. pineapple cut in slices was preferred to cubes.

Abstract: the purpose of this research was to determine the smallest effective concentration of sodium hypochlorite (naocl) for intact fruit disinfection as well as to evaluate the use of the same disinfectant product for sanitization of the fresh-cut 'pérola' pineapple. fruits were washed and disinfected with chlorine solutions (100, 150 or 200mg.l-1) for 2 minutes. after approximately 24 hours of cold storage, fruits were mechanically peeled and sliced. slices were dipped in 20mg.l-1 of chlorine solution or pure water (control), for 30 seconds. after that, the liquid in excess was drained and the slices were placed in polyethylene terephtalate packages and stored at 4 ± 1oc during 16 days. microbiological analyses were made every 3 days for mesophile aerobic, mold and yeast counts, and total and fecal coliforms determination. total and fecal coliforms were not detected in the treatments during 16 days of cold storage. the intact fruit disinfection (200mg.l-1) associated with sanitization of pineapple slices with 20mg.l-1 of chlorine solution provided smaller microbial population, showing that these operations are essential in order to get fresh-cut vegetables with sanity warranty to the consumer.

Investing on the CAPM Pricing Error  [PDF]
José Carlos de Souza Santos, Elias Cavalcante Filho
Technology and Investment (TI) , 2017, DOI: 10.4236/ti.2017.81006
Abstract: We tested an investment strategy based on the pricing error of the CAPM model. Starting with the Markowitz (1952) [1] methodology, we replaced the standard expected returns vector with the expected errors vector from the CAPM model, assuming that such errors are nonzero and persist over time. When evaluated over the entire examined period, all of the resulting portfolios outperformed the market portfolio. Except for some shorter periods, our hypothesis was fully confirmed. That is, the performance of our alpha portfolios was significantly better than the market portfolio. In other words, the pricing error of the CAPM model seems to be nonzero and to have an inertial component.

Sources of small family farm production inefficiency, rec?ncavo region, Bahia, Brazil
Pereira Filho, Carlos Augusto;Ferreira Filho, Joaquim Bento de Souza;
Revista de Economia e Sociologia Rural , 2003, DOI: 10.1590/S0103-20032003000100004
Abstract: the main objective of this study was to identify and analyze the sources of inefficiency in family operated small agricultural properties in the brazilian state of bahia?s rec?ncavo region from a sample of 44 producers. a non-parametric approach, in the context of cost minimizing behavior under constant returns to scale, was used to estimate the indices of technical, scale, allocative, and total (economic or cost) efficiency. results indicated that the largest source small family farm inefficiency in the rec?ncavo region is allocative inefficiency, that is to say, the non-observance of price relationships when making production decisions. on the average, 79.1% of these farms? total inefficiency is due to allocative inefficiency, 9.3% to technical inefficiency, and 11.7% to scale inefficiency.
