In this work, the thermodynamic equilibrium and applying of PEG4000/Phosphate ATPS on the purification of bromelain extracted from pineapple was studied. A rigorous study of the equilibrium curves and tie-line length from PEG4000/phosphate ATPS were done for the pH 6-11 at 25ºC. Results showed that there was augment in the PEG and salt contents with the high pH value from PEG4000/Phosphate ATPS and two-phase formation needed only increasing the PEG content. Two tie-line length at pH 11 from PEG4000/Phosphate ATPS were optimal condition for bromelain purification, one on composition of 14% PEG and 13% salt and other at 12.6% PEG and 12.2% salt, while a 25-62 folds of enzyme was found. SDS-PAGE electrophoreses had one band only, which showed that bromelain...

A pulsed-cap microcolumn was used for bromelain extraction from pineapple juice by reversed micelles. The cationic micellar solution used BDBAC as the surfactant, isooctane as the solvent and hexanol as the co-solvent. In order to capture the dynamic behavior and the nonlinearities of the column, the operating conditions were modified in accordance with the central composite design for the experiment, using the ratio between the light phase flow rate and the total flow rate, and the time interval between pulses. The effects on the purification factor and on total protein yield were modeled via neural networks. The best topology was defined as 16-9-2, and the input layer was a moving window of the independent variables. The neural model successfully...

The main aim of this study was to optimize the conditions for bromelain extraction by reversed micelles from pineapple juice (Ananas comosus). The purification was carried out in batch extraction and a micro-column with pulsed caps for continuous extraction. The cationic micellar solution was made of BDBAC as a surfactant, isooctane as a solvent and hexanol as a co-solvent. For the batch process, a purification factor of 3 times at the best values of surfactant agent, co-solvent and salt concentrations, pH of the back and forward extractions were, 100 mM, 10% v/v, 1 M, 3.5 and 8, respectively. For the continuous operation, independent variables optimal point was determined: ratio between light phase flow rate and total flow rate equal to 0.67 and 1 second...

Water loss, sucrose gain and the variation in concentration of other natural fruit sugars (glucose and fructose) were studied during osmotic dehydration of pineapple slices (0.6 mm thick) in sucrose solution (60 % w/w) at three temperatures (30, 40 and 50ºC). As temperature increased from 30 to 50ºC, the apparent moisture and sucrose diffusivities (Dw and Ds) increased 3.8 and 2.8 times, respectively; therefore, the dehydration efficiency index (Dw/Ds) increased with temperature. The loss of glucose and fructose increased with temperature too. It was found that the solute content was a linear function of the moisture content and this relation was independent of the temperature during the first 600 minutes of dehydration.

Banana, papaya and pineapple are the most consumed tropical fruits in the world, being Brazil one of the main producers. Fungi Colletotrichum musae, Colletotrichum gloeosporioides and Fusarium subglutinans f.sp. ananas cause severe post harvest diseases and losses in fruits quality. The aim of this work was to evaluate the effectiveness of five monoterpenes to inhibit the mycelial growth and conidia germination of these three phytopathogens. The monoterpenes citral, citronellal, L-carvone, isopullegol and a-pinene were diluted in ethanol to final concentrations from 0.2 to 1%. All monoterpenes were found to inhibit the growth of the three studies fungi in a dose-dependent manner. Citral was the most effective of the oils tested and showed potent fungicidal...

Abstract This paper describes the application of the solid-phase microextraction (SPME) technique for the determination and monitoring of the volatile profile of minimally-processed pineapple fruit stored at various temperatures (-12 °C, 4 °C and 25 °C) for different periods (1, 4 and 10 days). The SPME fiber coating composed of Car/PDMS presented the best performance. The optimal extraction conditions obtained through a Doehlert design were 60 min at 35 °C. The profiles for the volatile compounds content of the fruit at each stage of storage were determined by gas chromatography-mass spectrometry (GC-MS). The variation in the volatile profile over time was greater when the fruit samples were stored at 25 °C and at -12 °C compared to 4 °C. Thus, according...

Brazil is the third largest producer of pineapple (Ananas comosus) and the market for fresh pineapple is sustained by the Hawaii and Perola cultivars. In this work the Perola cultivar was divided into three main parts, shell, core and pulp, for characterization. Moisture in the pulp was higher (between 10 and 15%) than in the shell and core. The amount of protein was higher in the core (35%) than in the pulp and shell. Perola contained relatively low concentrations of total ascorbic acid in the edible parts, although higher levels of ascorbic acid in the shell. Citric acid corresponded to almost 60% of the total organic acids. The total soluble sugars [~7-12% (FW)] were predominantly sucrose, fructose and glucose. The core had almost twice as much total...

The present research aimed to develop an edible coating incorporated with mint essential oil, evaluate its effectiveness in inhibiting in vitro microbial development, and improve both quality and shelf-life of fresh-cut pineapple. Mint essential oil-containing edible coatings showed in vitro antimicrobial efficiency against Escherichia coli and Salmonella Enteritidis. Titratable acidity, pH, and texture were not affected (P>0.05) by coating or storage time. Mass loss was not higher than 1.0% after the 6th day of storage. No effect of storage time and coating on total soluble solids was observed. Mint essential oil-containing coatings inhibited the growth of yeasts and molds in fresh-cut pineapple. Compared to uncoated and control-coated samples, mint...

Ocorrencia de Thecla basalides em abacaxizeiro na Paraiba.

Incidencia de broca e fusariose em fruto de abacaxizeiro.

CHOAIRY, S. A.; SANCHES, N. F.; VILARDEBO, A..

No periodo de 1977/78, foi conduzido no Municipio de Mari, PB, um ensaio com a cultivar Smooth Cayenne, onde os pesos e tipos de mudas variam de acordo com as epocas das induções florais, as quais foram feitas de outubro de 1977 a julho de 1978. Pelos resultados obtidos observou-se que a medida em que o indice de pluviosidade aumentou, no periodo de desenvolvimento floral, houve um sensivel decrescimo de ataque da broca do fruto (Thecla basalides) e maior incidencia de fusariose (Fusarium subglutinans).

Trabalho conduzido na Fazenda Nossa Senhora de Lourdes, Municipio de Mari, PB, no periodo de 1977 a 1980, com o objetivo de estudar a incidencia da broca (Thecla basalides) e da fusariose (Fusarium subglutinans) do fruto do abacaxizeiro (Ananas comosus) cultivar Smooth Cayenne. Foram efetuadas induções do florescimento no periodo de outubro a maio. Observou-se uma maior incidencia de fusarium e menor infestacao de broca quando o desenvolvimento floral ocorreu no intervalo de janeiro a maio, epoca de maior precipitação pluviometrica. A ocorrencia de maior precipitação pluviometrica refletiu no aumento da incidencia de Fusarium e diminuição de infestação da broca do fruto.

ZEN, A. C.; CHOAIRY S. A..

Dada a importancia da abacaxicultura no Estado da Paraiba e a pouca informação sobre a presença de nematoides associados a este cultivo, coletaram-se 10 amostras de raizes e 13 de solo da rizosfera de abacaxizeiro (Ananas comosus) cultivares Perola e Smooth Cayenne, no Municipio de Mari, para analise nematologica. Foram verificadas as especies Pratylenchus brachyurus, Meloidogyne incognita, Rotylenchulus reniformis, Helicotylenchus dinystera, Macroposthonia ornata, Tylenchorhynchus sp. e Tylenchus sp. Observaram-se altas populações de Pratylenchus brachyurus associadas a um sistema radicular reduzido e a plantas pouco desenvolvidas sendo este nematoide o principal problema nematologico do abacaxizeiro no Estado da Paraiba.

O estudo foi realizado na Estação Experimental de Abacaxi, em Sapé, PB, bo periodo de maio/81 a novembro/1982, com o objetivo de controlar a broca e a fusariose do fruto do abacaxizeiro (Ananas comosus). Foram usadas mudas tipo rebentao da cultivar Smooth Cayenne plantadas em espaçamento de 70 x 30cm. O experimento foi delineado em blocos completos ao acaso com seis tratamentos e quatro repetições. Os tratamentos foram: 1) Testemunha, 2) Paration metilico a 0,1% do i.a., 3) Carbary 85 PM a 0,25% do i.a., 4) Captafol a 0,1% do i.a., 5) Paration metilico + Captafol e 6) Carbaryl + Captafol. Os inseticidas testados não foram eficientes no controle da broca do fruto. O Carbaryl foi eficiente no controle da fusariose enquanto que as combinações do Captafol x...
