Caracterização físico química de α - quitina em exoesqueletos de escarabeídeos (Strategus sp.) e aproveitamento da biomassa residual para obtenção de quitosana
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de QuímicaQuímicaUTFPR, 2017-11-28)
In this study, the physical-chemical structure of the exoskeleton of scarabeids of the genus Strategus sp. was characterized along the insect's chitonous body. Elytras, paws and abdomens were submitted to acid and alkaline ...
Chitosan/chondroitin sulfate aerogels with high polymeric electroneutralization degree: formation and mechanical properties
(Walter de Gruyter GMBH, 2018-04)
The formation of ultralight, highly porous solid materials (porosity higher than 99 %) containing equivalent molar amounts of chitosan (CS) and chondroitin sulfate (ChS) is presented. First, we show protocols to produce ...
Culinary practices mimicking a polysaccharide-rich recipe enhance the bioaccessibility of fat-soluble micronutrients
(2016-11-01)
This study was carried out to assess the impact of heat processing of a complex emulsion on the behavior of fat soluble micronutrients (FSM) in a traditional Tunisian dish. A simplified recipe involved, dried mucilage-rich ...
Semipreparative enantioseparation of methamidophos by HPLC-UV and preliminary in vitro study of butyrylcholinesterase inhibition
(Wiley-Blackwell, 2012-02-01)
Many chiral pesticides are introduced into the environment as racemates, although their pesticidal activity is usually the result of preferential reactivity of only one enantiomer, while the other enantiomer may have toxic ...
Natural polysaccharides and microfluidics: A win-win combination towards the green and continuous production of long-term stable silver nanoparticles
(Elsevier Ltd, 2018-08-25)
The present work combines the use of microfluidic reactors and green chemicals such as glucose and starch to achieve a continuous production of silver nanoparticles that have been successfully tested as excellent antibacterial ...
Synthesis and characterization of a starch-modified hydrogel as potential carrier for drug delivery system

Compositional changes in cell wall polysaccharides from five sweet cherry (Prunus avium L.) cultivars during on-tree ripening
(American Chemical Society, 2014-12)
Excessive softening is a major cause of postharvest deterioration during transportation and storage of fresh cherries. In continuing our studies to identify the factors determining the textural differences between sweet ...
