“…It was also possible to check the influence of eugenyl acetate concentration comparing assays 1, 4 and 6, for which the same temperature and pressure conditions (308 K and 8 MPa) were adopted. When lower concentrations of eugenyl acetate were used (assay 6), an increase of encapsulation efficiency occurred, which was similar to the results obtained by Boschetto et al (2014) and Franceschi et al (2008a), using the same technique in the encapsulation of bixin and bcarotene, respectively, and by Franceschi et al (2008b) for the micronization of theophylline.…”

“…From these results it can be seen that, for all assays, small particle sizes were obtained, ranging from 0.061 lm (run 4) to 0.276 lm (run 7). The particle size obtained here was smaller or similar to those reported by Boschetto et al (2014), Machado et al (2014), Priamo et al (2010) and Franceschi et al (2008a) for the precipitation of pure PHBV, 0.20-0.55 lm, 0.13-0.26 lm, 0.7-1.1 lm and 0.28 lm-0.57 lm, respectively. Azeredo (2005) and Matté and Rosa (2013) affirmed that nanoparticle size should be smaller than 0.2 lm and microparticle from 0.5 to 5000 lm.…”

“…For the encapsulation of eugenyl acetate, the experimental conditions used were based on the work of Boschetto et al (2014): solution flow rate of 1 mL min -1 , anti-solvent flow rate of 20 mL min -1 , PHBV concentration fixed at 20 mg mL -1 in the organic solution. Dichloromethane was used as solvent and CO 2 was used as anti-solvent by SEDS technique.…”

“…A sample of eugenyl acetate and PHBV was weighed and was dissolved in dichloromethane and the solution was analyzed using UV-VIS spectrophotometer (FEMTO, model 800XI, Brazil), with an absorbance at 320 nm. The encapsulation efficiency (EE %) of eugenyl acetate in each run were evaluated by comparison of the results with a standard curve using equation below (Boschetto et al 2014 where the theoretical loading percentage of eugenyl acetate encapsulated was the ratio between the mass of eugenyl acetate and the total mass of eugenyl acetate and PHBV used in the precipitation experiments. It was assumed that the ratio between eugenyl acetate and PHBV remained constant after the precipitation.…”

Eugenyl acetate obtained via enzymatic esterification using Lipozyme TL IM enzyme was encapsulated in biopolymer poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV) through solution-enhanced dispersion by supercritical fluids (SEDS). Produced particles were characterized by SEM and confocal microscopy techniques and in addition in vitro release assays were performed in isopropanol and ethyl acetate. Experimental micronization conditions comprised 8 and 10 MPa, 308 and 313 K and eugenyl acetate concentration ranging from 5 to 20 mg mL, keeping PHBV concentration constant (20 mg mL in dichloromethane). The maximum encapsulation efficiency was 58.0 % for 5 mg mLof eugenyl acetate at 8 MPa and 308 K. The morphology of the encapsulated particles for most of the trials was spherical, with particle size ranging from 0.061 to 0.276 μm. Regarding the release in ethyl acetate and isopropanol solvents the higher the affinity of the encapsulated ester of these solvents, the faster the release was observed. These results demonstrate the importance of essential clove oil esterification reaction and encapsulation of the ester by SEDS method so that this encapsulated ester can be used in different industrial applications.

New Starches are the Trend for Industry Applications: A Review

Starch is widely consumed by humans as an inexpensive and stable available carbohydrate source, and much work has been performed on the structure, functionality and applicability of starches. Although conventional sources of starch, such as corn and potato, other sources with improved properties are becoming significant to allow simpler and more robust processes. The feasibility of the use of new starches, i.e., legume, seed and palm, as renewable materials for commercial application may provide cost reduction of raw material in industries. Little information is available on the structure, properties and practical applicability of non-conventional sources of starch. Thus, it is necessary that these starches be studied to obtain and report their structural parameters, information that is required to gain competitiveness in an international-scale industry. A review of properties, applications, future trends and perspectives of some new starches is presented in this review.

Candida rugosa lipase (CRL) was immobilized on an eco-friendly support poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV), by physical adsorption, using different ionic liquids (ILs) as immobilization additives. This was to investigate the influence of cationic core ([C4mpy]Cl, [C4min]Cl), of anions ([C4min]Cl, [C4min]N(CN)2, [C4min]Tf2N), and of cation chain length ([C2min]Tf2N, [C4min]Tf2N) in the immobilization process. The immobilized biocatalysts (IB) were characterized with respect to the morphological, physico-chemical properties, total activity recovery yield (Ya), and biochemical properties of more efficient IB were evaluated. Initially, it was found that the change of cationic core did not influence in Ya compared to the control. With change of anions, it was seen that the best result was obtained for the more hydrophobic anion (Tf2N), and finally increasing the cation chain length increased Ya. IB most efficient with [C4min]Tf2N obtained 78 % of Ya, more than twice the control value (30 %) and a considerable enhancement of operational stability compared with the control.
