AB  - In the present work, we describe the chemical synthesis of 3-HFAs as prominent derivatives of fatty acids and assess if they could be applied as phase change materials (PCM). In addition, 3-HFAs were obtained by depolymerization of a bacterial biopolymeric material, polyhydroxyalkanoate. Thermal properties of 3-hydoxyoctanoic, decanoic, and dodecanoic acids are reported for the first time. These materials showed the potential to be applied as PCM in temperature range from 33 degrees C to 66 degrees C. In order to expand the temperature range for application of 3-HFAs as PCM, eutectic mass ratios of three kinds of binary mixtures of 3-HFAs were calculated, and their properties were predicted using the Schroder-van Laar equation. Thermal properties of these mixtures were validated by differential scanning calorimetry (DSC) analysis. These results showed that eutectics considerably expanded the scope of applications of 3-HFAs as PCMs. 3-HFAs originating from biotechnologically obtained polyhydroxyalkanoates also showed potential to be applied in development of PCMs.

AB  - This study aimed to estimate the quality (in terms of standard chemical parameters, total antioxidative activity /AO/ and thermal properties) of the fresh strawberry (Fragaria xananassa L. Duch.), raspberry (Rubus idaeus L.) and blackberry (Rubus fruticosusL.) samples grown in the Western Serbia. The examined blackberry variety was found to exhibit the most potent AO (DPPH /2,2-diphenyl-1-picrylhydrazyl/ assay, EC50 4.05 +/- 0.22 mu g and ARP 0.25 +/- 0.03 mu g(-1); Hydroxo-Perhydroxyl Mercury(II) Complex /HPMC/ assay, 0.072 +/- 0.007%/mu L), due to the enriched contents of both total phenolics and anthocyanins. It was actually followed by the raspberry and strawberry samples. Unlike the aforementioned trend for AO, thermal behaviour of all samples was similar. This is first time ever that a DC polarographic HPMC assay has been applied for the characterisation of the fresh berry fruits. Further studies aiming to screen total AO of the soft fruit during growth, storage and processing might be well facilitated by the application of this low cost, rapid, easy-to-handle and reliable electrochemical assay.
