| In this work, alginate-whey protein was used as wall materials for encapsulating Lactobacillus delbrueckii subsp. bulgaricus (L. bulgaricus). The characteristics of encapsulated and free L. bulgaricus showed that the free L. bulgaricus lost viability after 1 min exposure to simulated gastric fluid (SGF) at pH 2.0 and 2.5. However, the viability of encapsulated L. bulgaricus did not decrease in SGF at pH 2.5 for 2 h incubation. The viable numbers of encapsulated L. bulgaricus decreased less than 1.0 log unit for 2 h incubation in SGF at pH 2.0. For bile stability, only 1.2 log units and 2.0 log units viability of the encapsulated L. bulgaricus was lost in 1 and 2% bile for 1 h exposure, respectively, compared with no survival of free L. bulgaricus under the... |

| Stability during storage is a limiting factor in the development and use of bioinsecticides. This study aims to evaluate the compatibility of the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana with components used in encapsulated formulations and to evaluate shelf-life in formulations with B. bassiana. Sodium alginate and maltodextrin, hemicellulose, and dimethyl sulfoxide solvents were evaluated. Compatibility was evaluated by mixing the components with PDA, and the parameters evaluated were vegetative growth, sporulation and viability. The formulations of fungi were prepared in various concentrations of sodium alginate and then added drop-wise to calcium chloride. To evaluate the stability, formulations were stored at 26.5, 4.0, and... |

| ABSTRACT: The aim of this work was to demonstrate a detailed study of the controlled release of the herbicide Tebuthiuron (TBH) encapsulated in microparticles of calcium alginate (Ca-ALG), to evaluate the phytotoxicity in different concentrations of herbicide (4, 6 and 8 g L-1), and their correlation with the depth of leaching using bioindicator plants. The Ca-ALG microparticles were prepared from the crosslinking of sodium alginate by Ca++ containing varied amounts of TBH supplied in calcium chloride (CaCl2) aqueous solution. The results showed that TBH herbicide, when encapsulated, leached to shallow depths relative to the conventional, non-encapsulated herbicide (which moved to a depth of 40-50 cm). The concentration of 4 g L-1 was the one that leached... |

| The present research aimed to elucidate which aspects of immune responses in Diatraea flavipennella are suppressed by the parasitoid Cotesia flavipes, thus, ensuring parasitism success. We investigated the presence of apoptosis in fat body cells through the TUNEL technique. According to the results, reduced levels of nitric oxide and phenoloxidase activity were observed in larvae parasitized for three days, and reduced total number of hemocytes, after three and seven days. An increase in plasmatocytes and decrease in spherulocytes numbers were observed in the differential count on the third day of parasitism. The number of melanized microspheres in parasitized larvae was low and indicated less intense melanization. The ultrastructural analysis confirmed... |

| Abstract Effects of encapsulated (e) sodium tripolyphosphate (STP), sodium pyrophosphate (SPP) and various combinations of encapsulated and un-encapsulated (u) forms of these polyphosphates on lipid oxidation in the cooked ground beef during storage (0, 1, 7 d at 4 0C) were determined. pH, color, cooking loss (CL), thiobarbituric acid reactive substances (TBARS), lipid hydroperoxide (LPO) and soluble orthophosphate (OP) analysis were conducted. Study results indicated that STP increased pH, whereas SPP decreased pH compared to control (p<0.05). SPP was determined as the most effective polyphosphate type to inhibit lipid oxidation (p<0.05). In addition, the use of eSPP significantly reduced OP content compared to uSPP (p<0.05). The lowest TBARS... |

| Abstract Precision mechanized sowing of sugarcane has been delayed due to germination failures caused in sowing process by pieces of sugarcane, generating economic losses by reducing production. The aim of this study was to evaluate different polymers and cultivars of sugarcane to elaborate artificial seed CP-54, seed germination and quality of sugarcane plants. An experiment was carried out in two stages in experimental field of the Colegio de Postgraduados Campus Tabasco, Mexico. Results indicate that the best physical stage of artificial seed CP-54 was obtained in Mex 69-290, Mex 68-P-23 and CP 72-2086 cultivars encapsulated with starch polymers and sodium alginate. Artificial seed CP-54 germination was 100 and 84% encapsulated with starch and alginate... |

| O consumo elevado de lipídios de baixa qualidade pode trazer sérios danos à saúde, e uma alternativa para a melhoria destes é o desenvolvimento de óleos com propriedades funcionais através da interesterificação utilizando lipases. A encapsulação é um método utilizado para melhorar o poder catalítico das lipases, podendo afetar sua atividade e estabilidade, alterando sua reutilização e viabilidade industrial. O objetivo deste trabalho foi, portanto, avaliar o impacto do método de encapsulação por gelificação ionotrópica na atividade enzimática de lipases produzidas por Aspergillus niger. A gelificação das enzimas com alginato foi eficiente e demonstrou loading, eficiência e eficácia de encapsulação com valores de 1,17%, 72,2% e 88% respectivamente. Os géis... |

| O objetivo deste trabalho foi avaliar a funcionalidade da oleoresina de páprica microencapsulada em goma-arábica e amido de arroz/gelatina, incorporada nos sistemas-modelo bolo e gel de gelatina. Avaliou-se a cor por meio de medida instrumental e aceitação sensorial por atributos de aparência e aceitação global. O pigmento encapsulado solubilizou-se, tingiu e se distribuiu uniformemente nos bolos, os quais apresentaram boa aceitação global. Nos géis, a goma apresentou desempenho superior ao amido/gelatina quanto à aparência, porém, todos os tratamentos obtiveram baixa aceitação global. A presença da oleoresina microencapsulada não interferiu negativamente no sabor, aroma ou textura dos sistemas analisados. |

| ABSTRACT This study aimed to evaluate the teratogenic and hepatotoxic potential of the usnic acid encapsulated into PLGA-microspheres. In total, 12 female Wistar rats in pregnancy were randomly distributed in the control group (n= 6) that received 1.0 mL of physiological solution and treatment group (n= 6) that received 25 mg/kg of encapsulated usnic acid by oral administration. All females were euthanized at day 20 of pregnancy and their fetuses were removed and analyzed. During the pregnancy was observed a reduction in weight gain. There was no difference in serum transaminases levels analyzed as well as any difference in liver weight in both groups. The histomorphometric analysis of the liver from the treatment group revealed an increase in number of... |

| ABSTRACT In vitro rhizome production, encapsulation and cold storage of Acorus calamus were attempted for its propagation and ‘true-to-type’ conservation. Shoot cultures were initiated using underground rhizome buds, on 6-benzyladenine (BA) containing Murashige and Skoog (MS) medium. Maximum microrhizome production was observed in presence of 33.3 µM BA, on modified MS medium containing 6% sucrose, 100 mg/L citric acid and 1 g/L polyvinyl pyrrolidone-40. Synthetic seeds were produced from regenerated microtubers by encapsulation in calcium alginate beads. These synthetic seeds were stored in complete darkness at 100C temperature for different durations for mid-term conservation. After cold storage, synthetic seeds were re-cultured in vitro, 100% survival... |
