Microencapsulation of cashew apple (Anacardium occidentale, L.) juice using a new chitosan–commercial bovine whey protein isolate system in spray drying

Development of thiamine and pyridoxine loaded ferulic acid-grafted chitosan microspheres for dietary supplementation

“…The theoretical yield was calculated as 25.26 g considering initial amount of 20 g chitosan and 5.26 g of grafted ferulic acid (calculated from grafting ratio). The product yield can be considered satisfactory as similar yields for microencapsulation through spray drying were reported in recent literature (Klein et al 2015;Bastos et al 2012). Total encapsulation efficiency (TEE) was determined as ratio of actual content and theoretical content (2 g thiamine/pyridoxine in 25.26 g microspheres) of thiamine and pyridoxine per gram of the microspheres.…”

“…It is important to note that the particle size was less than 10 μ and particles were homogeneous in dimension. This is important in food application since these factors are directly related to controlled release of the loaded bioactive compound and ease of uptake by cells (Bastos et al 2012). Zeta potential is an indicator of the surface charge property of microspheres.…”

Nanostructuring Biopolymers for Improved Food Quality and Safety

“…As discussed, both polysaccharides and proteins have advantages and limitations as encapsulating agents. Therefore, combinations of them have also been studied as wall materials with the aim of improving the attributes of the individual biopolymers (Bastos et al, 2012;Fernandes et al, 2014;Smilkov et al, 2014). For instance, addition of proteins to MDs, which are considered to be one of the best thermal defenders (Munin and Edwards-Lévy, 2011) for microencapsulation by spray-drying, allows it to increase the powder recovery of the materials (Muzaffar and Kumar, 2016;Shi et al, 2013), while incorporation of dextrins to proteins as encapsulant material for fish oil increased its oxidative stability (Kagami et al, 2003).…”

Sistemas microestruturados contendo extratos de Chamomilla recutita L. para aplicações dermocosméticas

“…Além de todas as bioatividades da quitosana apresentadas acima, um fato que também tem tornado este polímero bastante atrativo para a produção de micropartículas destinadas a aplicação tópica é sua interação com a pele. Por ter característica catiônica, a quitosana tem a capacidade de bioaderir à pele, que é aniônica, o que mantém o ativo por mais tempo em contato com a mesma (ALVARENGA, 2011;BASTOS et al, 2012;BOWEY;NEUFELD, 2010;FELT;GURNY;BAEYENS, 2001;GELFUSO et al, 2011;VENTURA et al, 2011).…”

“…Já para os processos de SDO e SFDO, mi é referente à massa de óleo mais a massa de quitosana adicionadas em cada experimento. (BASTOS et al, 2012;MARTINS et al, 2013). BOUTIN, 2009;FAN et al, 2008;JACQUES et al, 2007;LUTHRIA;BISWAS;NATARAJAN, 2007…”
