Stability of encapsulated and non-encapsulated anthocyanin in yogurt produced with natural dye obtained from Solanum melongena L. Bark Rev. Bras. Frutic.
Barretto,Flavia Jamille de Figueiredo Paes; Clemente,Heleni Aires; Santana,Andrea Lopes Bandeira Delmiro; Vasconcelo,Margarida Angélica da Silva.
Abstract This research evaluated the stability of non-encapsulated and spray-dried encapsulated anthocyanin from Solanum melongena L. bark as a natural dye in yogurts. Anthocyanin was extracted using 70% cereal alcohol acidified with citric acid at pH 2.0. Extract spray-drying was defined using the experimental design (22), with drying temperature (°C) and carrier concentration (Gum arabic) as independent variables. The response variable adopted was the total monomeric anthocyanin content. The following analyses were performed: color; total monomeric anthocyanins; total phenolic contents; antioxidant activity using the DPPH• (1,1-diphenyl-2-picrylhydrazyl) radical; pH; and acidity. Yogurt degradation constant, half-life, and color retention percentage of...

Preparation and characterization of hydroxyapatite-coated iron oxide particles by spray-drying technique Anais da ABC (AABC)
Donadel,karina; Felisberto,Marcos D.V.; Laranjeira,Mauro C.M..
Magnetic particles of iron oxide have been increasingly used in medical diagnosis by magnetic resonance imaging and in cancer therapies involving targeted drug delivery and magnetic hyperthermia. In this study we report the preparation and characterization of iron oxide particles coated with bioceramic hydroxyapatite by spray-drying. The iron oxide magnetic particles (IOMP) were coated with hydroxyapatite (HAp) by spray-drying using two IOMP/HAp ratios (0.7 and 3.2). The magnetic particles were characterized by way of scanning electronic microscopy, energy dispersive X-ray, X-ray diffraction, Fourier transformed infrared spectroscopy, flame atomic absorption spectrometry,vibrating sample magnetometry and particle size distribution (laser diffraction). The...

Angel,Ruiz Cabrera Miguel; Espinosa-Muñoz,Lucía Carolina; Aviles-Aviles,Carlos; González-García,Raúl; Moscosa-Santillán,Mario; Grajales-Lagunes,Alicia; Abud-Archila,Miguel.
The objective of this study was to assess the effectiveness of the blends with different levels of lactose-maltodextrin (8:5, 10:5, and 12:5 % w/v) during the spray-drying of the passion fruit juice. The drying was carried out in a laboratory spray dryer (Pulvis GB 22 model) at two inlet air temperatures (180 and 190 ºC), and two air pressures (0.10 and 0.20 MPa). The moisture content, hygroscopicity and vitamin C retention were evaluated in the powder obtained. Response surface plots (p<0.05) showed that the lowest values of the moisture content and hygroscopicity were reached in the temperature range of 188-190 ºC and at 12:5 % (w/v) concentration of lactose-maltodextrin; the best vitamin C retention level occurred at 180 ºC and 0.2 MPa.

Encapsulation of lycopene using spray-drying and molecular inclusion processes BABT
Nunes,Itaciara Larroza; Mercadante,Adriana Zerlotti.
This study aimed to obtain encapsulated lycopene in a powder form, using either spray-drying or molecular inclusion with beta -cyclodextrin ( beta -CD) followed by freeze-drying. The encapsulation efficiency using spray-drying ranged from 94 to 96%, with an average yield of 51%, with microcapsules showing superficial indentations and lack of cracks and breakages. Lycopene- beta -CD complexes were only formed at a molar ratio of 1:4, and irregular structures of different sizes that eventually formed aggregates, similar to those of beta -CD, were observed after freeze-drying. About 50% of the initial lycopene did not form complexes with beta -CD. Lycopene purity increased from 96.4 to 98.1% after spray-drying, whereas lycopene purity decreased from 97.7 to...

Extraction, characterization and microencapsulation of isoflavones from soybean molasses Ciência Rural
Batista,Vanessa Sabrina Fagundes; Nunes,Graciele Lorenzoni; Viegas,Gabriela Ilha; Lucas,Bruna Nichelle; Bochi,Vivian Caetano; Emanuelli,Tatiana; Barin,Juliano Smanioto; Menezes,Cristiano Ragagnin de; Rosa,Claudia Severo da.
ABSTRACT: This study aimed to extract isoflavones from soybean molasses with different solvents, furthermore, the selected extract, which showed overall desirable characteristics was selected to evaluate the potentials of different encapsulating agents. The encapsulating agents employed for the study included 18% Maltodextrin DE20 (T1), 18% Hi-maize (T2), and a mixture of equal proportions of 9% Maltodextrin DE20 and 9% of Hi-maize (T3). Solvents such as 80% ethanol and methanol, and grain alcohol in varying different concentrations of 50 and 80% were used for the studies. The best solvent for the extraction of phenolics and total isoflavones was 50% cereal alcohol, this extract also presented higher antioxidant activity. Evaluation of the encapsulating...
