Patin fish (Pangasius micronemus), Gabus fish (Channa striata) and Bandeng fish (Chanos chanos) are the freshwater fish that are widely cultivated in Indonesia, fish oils extracted are believed has antioxidant activity. The goals of this study was (1) determining antioxidant activities using radical scavenging activity (RSA) 2,2’-diphenyl-1-picrylhydrazil (DPPH), (2) classifying of fish oil from different species and extraction method using principal component analysis (PCA) and cluster analysis (CA) and predicting antioxidant activities of fish oil from different species and extraction method using FTIR spectroscopy combined principal component regression (PCR) and partial least square regression (PLS). The results exhibit radical scavenging activity (RSA) of patin fish flesh oil (maceration dried samples using chloroform) giving highest RSA (23.57 ± 0.14). PCA and CA succesfully classify of fish oil from different species and extraction based on PC1 - PC2 score plots and grouping into 4 groups based on dendogram. Optimal PCR method were obtained from second derivative spectra at wavenumbers region 1440 – 1741 cm-1 with highest R2 (0,9794), lowest RMSEC (0,737), and lowest RMSEP (0,927) in calibration and validation models. From this study we can concluded FTIR spectroscopy combined with chemometrics can be classifying and predicting antioxidant activity of fish oil from different species and extraction method successfully.

The current industrial requirements for food naturalness are forcing the development of new strategies to achieve the production of healthier foods by replacing the use of synthetic additives with bioactive compounds from natural sources. Here, we investigate the use of plant tissue culture as a biotechnological solution to produce plant-derived bioactive compounds with antioxidant activity and their application to protect fish oil-in-water emulsions against lipid peroxidation. The total phenolic content of Bryophyllum plant extracts ranges from 3.4 to 5.9 mM, expressed as gallic acid equivalents (GAE). The addition of Bryophyllum extracts to 4:6 fish oil-in-water emulsions results in a sharp (eight-fold) increase in the antioxidant efficiency due to the incorporation of polyphenols to the interfacial region. In the emulsions, the antioxidant efficiency of extracts increased linearly with concentration and levelled off at 500 μM GAE, reaching a plateau region. The antioxidant efficiency increases modestly (12%) upon increasing the pH from 3.0 to 5.0, while an increase in temperature from 10 to 30 °C causes a six-fold decrease in the antioxidant efficiency. Overall, results show that Bryophyllum plant-derived extracts are promising sources of bioactive compounds with antioxidant activity that can be eventually be used to control lipid oxidation in food emulsions containing (poly)unsaturated fatty acids.

Abstract Subcritical water was used to provide propolis oil in water (O/W) nanoemulsions. To monitor and detect the main bioactive compounds of the prepared propolis extract, gas chromatography demonstrated that there were 47 bioactive materials in the propolis extract, among which pinostrobin chalcone and pinocembrin were the two key components. Effectiveness of two processing parameters such as the amount of saponin (0.5–2.0 g) and propolis extract (0.1–0.6 g), on particle size, polydispersity index (PDI), zeta potential, and antioxidant activity of the provided nanoemulsions, was evaluated. Results demonstrated that more desirable propolis O/W nanoemulsion, with minimum particle size (144.06 nm) and PDI (0.286), and maximum zeta potential (−21.71 mV) and antioxidant activity (90.86%) were made using 0.50 g of saponin and 0.53 g of propolis extract. Further analysis revealed that the prepared nanoemulsion based on optimum processing conditions had spherical shaped propolis nanodroplets in the colloidal solution with turbidity and maximum broad absorption peak of 0.08 a.u. and 292 nm, respectively. The prepared nanoemulsion had high antibacterial activity against both selected bacteria strains namely, Staphylococcus aureus and Escherichia coli.
