13. Characterization of microencapsulated cardamom (Elettaria cardamomum) oil extracted using supercritical fluids on a semi-industrial scale
Abstract The objective of this study was to find the optimal conditions to obtain cardamom oil extracted by SCF on a semi-industrial scale, with yields equal or superior to those obtained using the conventional methods, but with sensory quality and a technique competitive for international markets. In addition microcapsules were produced allowing for an incr

14. Anti-inflammatory, and antinociceptive effects of Campomanesia adamantium microencapsulated pulp
ABSTRACT Guavira fruits have antimicrobial, antioxidant, antinociceptive, and anti-inflammatory activities. Spray drying has been widely used in the food industry presenting good retention in bioactive compounds used to transform the pulp/fruit juice into powder form. Therefore, the present study has evaluated the anti-inflammatory and antinociceptive activi

15. ENCAPSULATION OF EXTRACT FROM WINERY INDUSTRY RESIDUE USING THE SUPERCRITICAL ANTI-SOLVENT TECHNIQUE
Abstract Grape pomace (seed, skin and stem) is a winery byproduct with high levels of biologically active compounds, such as antioxidants and antimicrobials, that could be converted into high added-value products. Since these components are easily degraded by oxygen, light and high temperature exposure, stabilization is important, for instance, by a microenc

16. DEVELOPMENT AND VALIDATION OF ANALYTICAL METHOD FOR PALM OIL DETERMINATION IN MICROCAPSULES PRODUCED BY COMPLEX COACERVATION
The microencapsulation of palm oil may be a mechanism for protecting and promoting the controlled release of its bioactive compounds. To optimize the microencapsulation process, it is necessary to accurately quantify the palm oil present both external and internal to the microcapsules. In this study, we developed and validated a spectrophotometric method to

19. Improved green coffee oil antioxidant activity for cosmetical purpose by spray drying microencapsulation
AbstractThe oil extracted by cold pressing unroasted coffee beans, known as green coffee oil, has been widely used for cosmetic purposes. The objective of this work was to prepare and characterize microcapsules containing green coffee oil and to verify its antioxidant activity under the effect of light, heat and oxygen. The encapsulating material was arabic

20. Microparticles containing guaraná extract obtained by spray-drying technique: development and characterization
AbstractGuaraná (Paullinia cupana Kunth, Sapindaceae) is well known for its dietary and pharmaceutical potential, and the semipurified extract of guaraná shows antidepressant and panicolytic effects. However, the low solubility, bioavailability and stability of the semipurified extract limit its use as a component of pharmaceutical agents. Delivery of the

23. Microencapsulation of babassu coconut milk
The objective of this study was to obtain babassu coconut milk powder microencapsulated by spray drying process using gum Arabic as wall material. Coconut milk was extracted by babassu peeling, grinding (with two parts of water), and vacuum filtration. The milk was pasteurized at 85 ºC for 15 minutes and homogenized to break up the fat globules, rendering t
