“…Also, the works reported by others support the observation made in this study. Modified tapioca starch as wall gave smaller particles size, and had higher ME as compared to native starch and MD in encapsulation of β-carotene (Loksuwan 2007), and GA had smaller size and higher ME compared to MD and MD:GA mixed as wall materials in encapsulation of rosemary (Rosenberg et al 1990). Therefore there were a reverse relation between the size of emulsions and particles, and ME.…”

The strain bacterium Dietzia natronolimnaea has propounded as a source for biological production of canthaxanthin. Because of sensitivity of this pigment, examine on its stability is important. In this study, stability of encapsulated canthaxanthin from D. natronolimnaea HS-1 using soluble soybean polysaccharide (SSPS), gum acacia (GA), and maltodextrin (MD) as wall materials was investigated at 4, 25, and 45°C in light and dark conditions during 4 months of storage. It was shown that the type of walls influenced the size of emulsion droplets; spray dried particles, microencapsulation efficiency (ME), and retention of canthaxanthin in microcapsules. SSPS and MD produced the smallest and the biggest emulsion droplets and spray dried particles, respectively. Microcapsules made with SSPS resulted in better ME and higher stability for canthaxanthin. Samples were degraded in all conditions, especially in light and 45°C. Degradation of microencapsulated canthaxanthin with SSPS and GA proceeded more slowly than did with MD. Regardless of the type of wall materials, total canthaxanthin contents of the microencapsulated products decreased by an increase in time or temperature. Also, samples exposed to light indicated less stability at 4 and 25°C when compared to the storage at dark conditions. According to the results of this study, SSPS can be considered as potential wall material for the encapsulation of carotenoids.

“…28 Images obtained by scanning electron microscopy (images not show) demonstrated that the microencapsulated material has predominantly rough surface, which is very common for this type of technique due to contraction of the particles during the fast drying. 29 Initially, we evaluated the Pp crude extract stability, employing writhing test for the antinociceptive activity evaluation. This assay was performed with free and microencapsulated Pp extract samples, representative of 0 (T0) and 180 (T180)-day times of the stability study.…”

As sementes de Pterodon pubescens Benth. (Pp), disponíveis comercialmente no Brasil, são utilizadas na medicina popular em preparações anti-inflamatórias, analgésicas e anti-reumáticas. O presente estudo demonstrou as propriedades antinociceptivas da mistura de isômeros 6α-hidroxi-7β-acetoxi-vouacapano-17β-oato de metila e 6α-acetoxi-7β-hidroxi-vouacapano-17β-oato de metila (C1) isolada de Pp, empregando modelos experimentais diferentes. Um estudo de estabilidade foi realizado para investigar a relação da microencapsulação por "spray-drying" na manutenção do efeito antinociceptivo. Para isso, amostras de C1 e extrato de Pp foram monitorados no estudo de estabilidade acelerada, avaliando tanto amostras microencapsuladas como não microencapsuladas. Foi observado que a amostra C1 possui atividade antinociceptiva, revelada pelos ensaios das contorções abdominais e de formalina; foi observada também atividade significativa antialodínica, mas não efeito anti-hiperalgésico. A microencapsulação manteve a atividade e integridade de C1 e do extrato bruto de Pp, demonstrando que a microencapsulação por "spray drying" é uma alternativa útil para aumentar o tempo de prateleira.Pterodon pubescens Benth. (Pp) seeds, commercially available in Brazil, are used in folk medicine in anti-inflammatory, analgesic, and anti-rheumatic preparations. The present study demonstrated the antinociceptive properties of isomers 6α-hydroxy-7β-acetoxy-vouacapan-17β-oate methyl ester and 6α-acetoxy-7β-hydroxy-vouacapan-17β-oate methyl ester (C1), isolated from (Pp), employing different experimental models. A stability study was performed to investigate the relationship of microencapsulation by spray-drying on the maintenance of antinociceptive action. Therefore, C1 and Pp extract samples were monitored in accelerated stability study, evaluating both microencapsulated and non-microencapsulated samples. It was observed that sample C1 possess antinociceptive activity revealed by writhing and formalin tests; C1 showed significantly anti-allodynic, but not antihyperalgesic effect; the microencapsulation maintained the activity and integrity of both, sample C1 and Pp crude extract; microencapsulation by spray drying is a useful alternative to increase shelf life.

The plant's crude alcoholic extract is used in folk medicine in antiinflammatory, analgesic, and anti-rheumatic preparations. 1,2 Phytochemical studies of Pterodon genus have revealed the presence of alkaloids, isoflavones and diterpenes. Furan diterpenes were identified and isolated from Pterodon species. [3][4][5][6][7] Authors have reported that furanoditerpenes possessing vouacapan skeleton are involved with the anti-inflammatory, antinociceptive and antiproliferative properties of Pterodon pubescens seed crude extract.

“…However, since flavors are volatile and labile compounds that are prone to evaporation and degradation, it is quite important to protect from flavor loss during drying. Bandari et al, 8) and Rosenberg et al,9) have studied the influence of process variables on the retention of flavors during spray drying. The main carriers used to encapsulate flavors for spray drying have been maltodextrin (MD), gum arabic, and modified starches.…”
