Strawberry pomace, waste of strawberry (Fragaria x ananassa) juice, is widely produced in food industry, and contains natural phenolic compounds. In this study, microencapsulation of phenolic powder obtained from strawberry pomace was achieved using different combinations of maltodextrin (MD) and gum arabic (GA). Microcapsules were prepared using a high‐speed homogenizer (HSH) and a high‐pressure homogenizer (HPH). During HPH, 50 and 70 MPa were chosen as pressures with different process cycles (3, 5, and 7). The objective of this research was to study the effects of different coatings, encapsulation techniques (HSH and HPH), and parameters (pressures and process cycles) on microcapsules. Microcapsules obtained after HPH had the highest encapsulation efficiencies. Process cycle had no effect in D[50] and D[32] values. Applying 70 MPa pressure resulted in higher efficiencies and smaller particle sizes. Microcapsules coated with MD:GA ratio of 6:4, prepared by HPH 70 MPa with 5 cycles had the highest efficiency.

Cytochrome P4501A and associated mixed-function oxidase induction in fish as a biomarker for toxic carcinogenic pollutants in the aquatic environment Arinc, E; Sen, A; Bozcaarmutlu, A (Walter de Gruyter GmbH, 2000-06-01) Polycyclic aromatic hydrocarbons (PAHs), dioxins, dibenzofurans, and polychlorinated biphenyls (PCBs) present in polluted environment induce cytochrome P4501A (CYP1A) isozyme in fish, which in turn results in a marked increased production of carcinogenic metabolites from PAHs. The induction of hepatic CYP1A in fish by certain classes of chemicals has been suggested as an early warning system, a "most sensitive biological response" for assessing environmental contamination conditions. This has implications f...
NONENZYMATIC BROWNING IN CLARIFIED APPLE JUICE AT HIGH-TEMPERATURES - A RESPONSE-SURFACE ANALYSIS Bayındırlı, Alev; YENICERI, A (Wiley, 1995-06-01) The effect of temperature and soluble solids on nonenzymatic browning in clarified and concentrated apple juice was analyzed by response surface methodology. Color development at 20, 40 and 60 Brix and temperatures ranging from 70-90C were compared over a time range of 30-180 min. The browning reaction was found to be dependent on soluble solid content as well as on the reaction conditions such as temperature and time. The model combines the effect of temperature, soluble solids content and time on color ch...
EFFECTS OF SEMPERFRESH(TM) AND JOHNFRESH(TM) FRUIT COATINGS ON POSTSTORAGE QUALITY OF ANKARA PEARS Şümnü, Servet Gülüm (Wiley, 1994-08-01) Pears were coated with different concentrations of Semperfresh or with Johnfresh edible coatings after storage for five months at 0C to determine the effects of coatings on poststorage quality. Coating levels were effective for extending the poststorage life and delaying ripening. Both Semperfresh and Johnfresh treated pears had better color, firmness, ascorbic acid, titratable acidity, soluble solid retention than control pears. Although Semperfresh was effective for the reduction of respiration and weight...
Chemocatalytic Upgrading of Tailored Fermentation Products Toward Biodiesel SREEKUMAR, Sanil; Baer, Zachary C.; GROSS, Elad; Padmanaban, Sasisanker; GOULAS, Konstantinos; Günbaş, Emrullah Görkem; ALAYOGLU, Selim; Blanch, Harvey W.; Clark, Douglas S.; Toste, F. Dean (Wiley, 2014-09-01) Biological and chemocatalytic processes are tailored in order to maximize the production of sustainable biodiesel from lignocellulosic sugar. Thus, the combination of hydrotalcite-supported copper(II) and palladium(0) catalysts with a modification of the fermentation from acetone-butanol-ethanol to isopropanol-butanol-ethanol predictably produces higher concentrations of diesel-range components in the alkylation reaction.
MATHEMATICAL-ANALYSIS OF VARIATION OF DENSITY AND VISCOSITY OF APPLE JUICE WITH TEMPERATURE AND CONCENTRATION Bayındırlı, Levent A. (Wiley, 1992-01-01) The effect of temperature and concentration on some of the thermophysical properties of apple juice was studied. Density and viscosity of apple juice at different sugar concentrations and temperature were utilized to derive a multiparameter model. The derived model satisfactorily represented the variation of density and viscosity of apple juice in the concentration and temperature ranges 14-39-degrees-Brix, 20-80 C, respectively.
