1. Extraction and analysis of the parietal polysaccharides of acorn pericarps from Quercus trees
Abstract Acorns produced by Quercus trees are currently underexploited and undervalued. To evaluate the commercial and health benefits of acorns, we examined the cell wall components of acorn pericarps from Quercus suber and Quercus ilex, growing in North-Western Algeria. Acorn pericarps were sequentially extracted and the polysaccharide fractions were analy

3. Physicochemical characterization and behavior of biocompounds of caja-manga fruit ( Spondias mombin L.)
Abstract The aim of this study was to evaluate the physicochemical changes and the antioxidant potential of caja-manga (Spondias mombin L.) fruit during its physiological development. The cycle comprised a period of 260 days after anthesis (DAA), set when the fruits were yellow-orange colored and easily detached from the pads. The results showed that the fr

4. Quality and antioxidant potential of byproducts from refining of fruit pulp
Abstract The potential use of byproducts from fruit processing has been evaluated in order to propose new uses as well as reducing costs and environmental impact. Most of the studies are focused on byproducts from primary transformation. However, byproducts from secondary transformation can reserve similar reuse opportunities. The aim of this study was to c

5. Colleters in Chamaecrista (L.) Moench sect. Chamaecrista and sect. Caliciopsis (Leguminosae-Caesalpinioideae): anatomy and taxonomic implications
ABSTRACT The genus Chamaecrista contains ca. 330 species organized into six sections, of which section Chamaecrista is the second largest (ca.75 species) distributed among six series, while the section Caliciopsis contains only two species. Colleters have been described in the genus Chamaecrista and they show potential taxonomic and phylogenetic significance

7. Ontogênese, função e evolução das traqueídes vasculares em Cactaceae, tendo como modelo o cacto colunar Pilosocereus aurisetus (Werdern.) Byles &G. D. Rowley / Ontogenesis, function and evolution of wide-band tracheids in Cactaceae: Ontogenesis, function and evolution of wide-band tracheids in Cactaceae: using Pilosocereus aurisetus as a model cactus.
Studies with wide-band tracheids have adressed phylogenetic and functional questions. Although these cells have been described as tracheids, with secondary cell walls thicker than 2µm, their recent register in different tissues of other families has pointed out that this definition may not be well established. The aim of the present study is to understand t

8. Modificações da parede celular de frutos do mamoeiro (Carica papaya L.) em diferentes estadios do desenvolvimento / Modifications of the cell wall of fruits of papaya (Carica papaya L.) at various stages of development
The plant cell wall is a unique component of plant tissues and its polysaccharide composition essential to understand food texture and its changes during post-harvestingl especially of climateric fruits, as is the case of papaya. The plant cell wall is composed of three domains: the first is formed by cellulose and hemicelluloses, the second of pectins and t

9. Efeito da radiação gama sobre a viscosidade de soluções de gelatina e pectina utilizadas na indústria de alimentos / Effect of gamma irradiation in the viscosity of gelatin and pectin solutions used in food industry
A pectina é uma substância polissacarídica originada de plantas, que pode ser utilizada como agente gelificante, estabilizante de compotas, em bebidas láticas e iogurtes. A gelatina, proteína, nesse caso de origem bovina, é principalmente utilizada como agente gelificante, pois, forma hidrogéis por resfriamento. O processo de irradiação por radiaç�

10. Quality of papaya submitted to 1-MCP in different exposition times. / Qualidade de mamÃo submetido ao 1-MCP em diferentes tempos de exposiÃÃo.
The papaya is a climateric fruit the transformations of which resulting from ripening occur rapidly after the collection of the physiologically mature fruit, triggered by ethylene production and increased respiratory rate. That characterizes it as a quite perishable fruit after collection. Given to that high perishibility, ripening control is fundamental to

11. Alteration in the composition of cell wall polysaccharides in Nicotina tabacum by modulating the expression of the uxs gene, coding for UDP-D-glucuronic acid decarboxylase enzyme (EC 4.1.1.35) / Alteração da composição dos polissacarídeos da parede celular de Nicotiana tabacum, pela modulação da expressão do gene uxs que codifica a enzima UDP-D-glucuronato descarboxilase (EC 4.1.1.35)
The plant cell wall is not only an essential structure for plants, but also an extremely important raw material in human economy. The plant cell wall has diverse utilities, for example, papermaking, textile fiber, civil construction. Polysaccharides, such as cellulose, hemicelluloses and pectins, are the major components of the primary plant cell wall (appro

12. Laranja 'Pêra' (Citrus sinensis L. Osbeck) minimamente processada: efeito de cloreto de cálcio e película de alginato de sódio na fisiologia e conservação / Minimally processed 'Pera' Orange (Citrus sinensis L. Osbeck): effect of calcium chloride and sodium alginate film on physiology and conservation
Changes in the profile of the consumer interested in healthier nutrition, associated with the practicality and convenience, have led to a new branch of food technology: minimal processing. In citrus, this processing will contribute to increased consumption of the fruit in natura, enabling the product to have added value and giving the consumer a new option.
