Alginate-pomegranate peels' polyphenols beads: effects of formulation parameters on loading efficiency BJPS
Zam,Wissam; Bashour,Ghada; Abdelwahed,Wassim; Khayata,Warid.
Calcium alginate beads containing pomegranate peels' polyphenol extract were encapsulated by ionic gelation method. The effects of various formulation factors (sodium alginate concentration, calcium chloride concentration, calcium chloride exposure time, gelling bath time maintaining, and extract concentration) on the efficiency of extract loading were investigated. The formulation containing an extract of 1 g pomegranate peels in 100 mL distilled water encapsulated with 3 % of sodium alginate cured in 0.05 M calcium chloride for 20 minutes and kept in a gelling bath for 15 minutes was chosen as the best formula regarding the loading efficiency. These optimized conditions allowed the encapsulation of 43.90% of total extracted polyphenols and 46.34 % of...

Assembly of HE800 exopolysaccharide produced by a deep-sea hydrothermal bacterium into microgels for protein delivery applications ArchiMer
Zykwinska, Agata; Marquis, Melanie; Sinquin, Corinne; Cuenot, Stephane; Colliec-jouault, Sylvia.
Assembly of biopolymers into microgels is an elegant strategy for bioencapsulation with various potential biomedical applications. Such biocompatible and biodegradable microassemblies are developed not only to protect the encapsulated molecule but also to ensure its sustained local delivery. The present study describes the fabrication of microassemblies from a marine HE800 exopolysaccharide (EPS), which displays a glycosaminoglycan (GAG)-like structure and biological properties. HE800 EPS was assembled, through physical cross-linking with divalent ions, into microgel particles and microfibers using microfluidics. The microparticle morphology was highly affected by the polysaccharide concentration and its molecular weight. A model protein, namely Bovine...

Characterization and evaluation of sensory acceptability of ice creams incorporated with beta-carotene encapsulated in solid lipid microparticles Ciênc. Tecnol. Aliment.
LIMA,Juliana Gobbi de; BRITO-OLIVEIRA,Thais Carvalho; PINHO,Samantha Cristina de.
Abstract The feasibility of incorporating beta-carotene-loaded solid lipid microparticles (BCSLM) into vanilla ice creams was investigated, through the physico-chemical characterization and evaluation of sensory acceptability of the products products. The BCSLM were produced with palm stearin as the lipid phase, hydrolyzed soy protein isolate as the surfactant, and xanthan gum as the thickener. The results showed similar values of proximate composition, total soluble solids, pH, and overrun for all formulations. On the other hand, colorimetric evaluations showed that the ice cream produced with partial substitution of artificial additives by BCSLM containing alpha-tocopherol presented a more intense color, while in the product with non-encapsulated...

Characterization and shelf life of β-carotene loaded solid lipid microparticles produced with stearic acid and sunflower oil BABT
Gomes,Graziela Veiga de Lara; Borrin,Thais Ribeiro; Cardoso,Lisandro Pavie; Souto,Eliana; Pinho,Samantha Cristina de.
Solid lipid microparticles were tested as microencapsulation systems for protecting β-carotene from degradation. Blends of long-chain (C18) solid lipids (70% stearic acid) and sunflower oil (30%) were used to produce lipid microparticles encapsulating the carotenoid. Polysorbate 80 (4%) was employed to stabilize the stearic acid microparticles. The concentration of β-carotene was monitored using spectrophotometry, the particle size distribution was measured by laser diffraction, the crystal structure was determined by wide angle X-ray diffraction (WAXD), and the thermal behaviour was characterized by differential scanning calorimetry (DSC) over a period of seven months. All of the systems had an average particle size smaller than 5 µm. To avoid β-carotene...

Cross-linked coacervates of cashew gum and gelatin in the encapsulation of pequi oil Ciência Rural
Alexandre,Joana de Barros; Barroso,Tiago Linhares Cruz Tabosa; Oliveira,Marília de Albuquerque; Mendes,Francisco Rogênio da Silva; Costa,José Maria Correia da; Moreira,Renato de Azevedo; Furtado,Roselayne Ferro.
ABSTRACT: Pequi oil is rich in bioactive compounds which can be encapsulated to increase protection against extrinsic environmental factors. A delayed degradation of pequi oil may occur by using microencapsulation technology, in addition to masking unpleasant flavors and aromas. Complex coacervation is a technique based on the electrostatic interaction between two oppositely charged biopolymers which form a matrix complexed around an agent of interest. However, cross-linking the particles is often necessary in order to make them more rigid. The objective of this research was to produce and characterize pequi oil microparticles in a cashew gum (CG) and gelatin (GE) matrix cross-linked with tannic acid. Cross-linked pequi oil microparticles were produced by...

Silva,Thaiane Marques da; Barin,Juliano Smanioto; Lopes,Eduardo Jacob; Cichoski,Alexandre José; Flores,Erico Marlon de Moraes; Silva,Cristiane de Bona da; Menezes,Cristiano Ragagnin de.
ABSTRACT: Technique of complex coacervation was used to produce microcapsules of Lactobacillus acidophilus La-5 encapsulated in gelatin and gum arabic which were then freeze-drying. Microcapsules were characterized using scanning electron and optical microscopy, and resistance of probiotics was evaluated during release into a simulated gastrointestinal tract and storage at different temperatures. The complex coacervation process produced microcapsules with a high encapsulation efficiency (77.60% and 87.53%), ranging from 127.14-227.05 μm with uniform distribution. Microencapsulation was an efficient approach to achieve significant protection of probiotics against simulated gastrointestinal conditions compared with free cells. Encapsulation also improved...

Effect of cellulose acetate phthalate and polyethylene glycol on physical properties and release of theophylline from microcapsules BJPS
Hussain,Amjad; Mumtaz,Ahmad Mehmood; Arshad,Muhammad Sohail; Abbas,Nasir; Latif,Abida; Shamim,Rahat; Bukhari,Nadeem Irfan; Hussain,Khalid.
ABSTRACT The present study describes the development of theophylline microcapsules by a non-solvent addition method and the effect of plasticizer addition on microencapsulation. The release was studied in distilled water and the data were analysed by various mathematical models for determining the mechanism of release. Prepared microcapsules were found to be spherical, free flowing and having more than 80% entrapped drug. The polymer - cellulose acetate phthalate and plasticizer - polyethylene glycol was considered to be affecting the properties of microcapsules including drug release (time for 50% drug release, T50). The formulation with the highest proportion of polymer and without plasticizer (F3) showed the slowest release with T50 = 4.3 h, while the...

Effects of storage conditions on phytochemical and stability of purple corn cob extract powder Ciênc. Tecnol. Aliment.
KAPCUM,Chutikarn; URIYAPONGSON,Juntanee.
Abstract Recently, purple corn cob has been gaining popularity for a dietary supplement and natural colorant. However, phytochemicals in waxy purple corn cob (WPC) are likely degraded during storage; thus, the microencapsulation by spray drying was used for lengthening those compounds. This work focused on the phenolic and anthocyanin content and antioxidant activity (AOA) in WPC extract microcapsules by hydroxypropyl beta-cyclodextrin (HPβCD) during storage at 4 and 30 °C for 60 days. The results revealed that only peonodin-3-glucoside at 30 °C was found as a higher decrease than 4 °C. Pelagonidin-3-glucoside and AOA were found more stable at both storage temperatures; however, the increase of protocatechuic acid and hydroxybenzoic acid were observed...

Barrera-Cubillos,Gloria Patricia; Gómez-Valderrama,Juliana Andrea; Rivero,Laura Fernanda Villamizar.
Abstract: Wettable powder formulations by microencapsulation of viral occlusion bodies (OBs) of both Spodoptera frugiperda multiple nucleopolyhedrovirus from Colombia (SfCOL) and a genotypic variant (SfCOL-A) were evaluated for controlling the fall armyworm S. frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) in maize crops. Microencapsulation preserved OBs activity after three months of storage at 35ºC, where insecticidal activity loss was not greater than 12%. Additionally, the formulation protected the OBs against inactivation caused by UV-B radiation, retaining its insecticidal activity after 6 hours of UV laboratory exposure, in contrast to unformulated viral suspensions, which presented an Original Activity Remaining (OAR) between 12.1 and 50%. Under...

Identification of phenolic compounds in pomegranate (Punica Granatum) seeds and soybean (Glicine Max) oils and its stabilization by spray drying. Repositório Alice
SILVA-JAMES, N. K.; FERREIRA, M. J. A.; NOGUEIRA, R. I.; FREITAS, S. P.; NASCIMENTO, L. da S. de M. do.
Pomegranate seed oil (PSO), even though highly sensitive to oxidation, has been extensively studied due to its bioactive potentials, assigned to the punicic acid, a polyunsaturated fatty acid, and several phenolic compounds. Combined with soybean oil (SO) we get an affordable product, rich in essential fatty acids. In this study we evaluate PSO and SO for phenolic and fatty acids compositions and encapsulate it by spray drying to increase its shelf life. Modified starch, maltodextrin and gum arabic are evaluated by a mixture design to get the better wall material composition. The content of punicic, a conjugated linolenic acid, and linoleic acids in PSO and SO were, respectively 75% and 54%. As expected, the phenolic acids were found at low concentration...

Microencapsulação de óleo de linhaça por spray drying: influência da utilização de diferentes combinações de materiais de parede. Repositório Alice
CARNEIRO, H. C. F..
O óleo de linhaça é um óleo rico em ácidos graxos poliinsaturados bastante susceptível à oxidação lipídica, que pode ocorrer durante o processamento, manipulação e estocagem, provocando o aparecimento de aromas desagradáveis e a redução de sua vida de prateleira. Nesse contexto, a microencapsulação por spray drying representa uma alternativa no sentido de proteger o óleo contra a oxidação, diminuir as reações do mesmo com o ambiente externo e facilitar seu manuseio. A maltodextrina é um amido hidrolisado muito utilizado como material de parede e possui vantagens como baixo custo, boa disponibilidade e eficiência na proteção contra oxidação; porém é deficiente em relação à capacidade emulsificante. Este trabalho teve como objetivo avaliar o efeito da...
