Abstract

This study aims to determine the effect of different lemon marinates on Polycyclic Aromatic Hydrocarbons (PAHs) and quality of chicken satay. The percentages of lemon used 0%, 5 %, 10 % and 15 %. Chicken meat was marinated for 10 minutes in a homogeneous. The study used a Nested Completely Randomized Design. Parameters used were physical quality (pH, cooking loss and WHC), chemical quality (moisture, fat and protein content) and Polycyclic Aromatic Hydrocarbons (PAHs). Data were analyzed using Analysis of Variance (ANOVA), if the results of statistical analysis significant or very significant differences were obtained Duncan's test (UJBD) and descriptive PAH. The results of statistical analysis showed that the use of lemons marinates with different proportions had a very significant effect (P<0,01) on pH, cooking loss, WHC and moisture, fat content had a significant effect (P<0,05) but had no significant effect (P>0,05) on protein content. Chicken satay with 15% lemon marinates showed non-detectable results PAH.  The study concluded that lemon marinates can reduce the content of PAH carcinogens and affect the quality of chicken satay. The lowest levels of PAHs were found in the chicken satay that was marinated with a 15% lemon marinates.

Abstract

The purpose of this research was to extract Andrographis paniculata using the Microwave Assisted Extraction (MAE) method at 4 radiation (4 minutes, 6 minutes, 8 minutes, and 10 minutes) and characterize the extract on phenolic content, flavonoid content, andrographolide content, antioxidant activity, and functional group using Fourier Transform Infrared Spectroscopy (FTIR). Radiation times of the MAE method had a significant effect on phenolic content, flavonoid content, andrographolide content, and antioxidant activity of Andrographis paniculata. Radiation time for 10 minutes of MAE gave higher phenolic, flavonoid, andrographolide, and antioxidant activity of Andrographis paniculata. The IR spectra of the Andrographis paniculate extract increased as the radiation time increased. The optimum radiation time was at 8 minutes with the result of phenolic content at 57.2 mg GAE /g, flavonoid content at 113.07 ppm, andrographolide at 763.47 µg/ml, antioxidant activity at 71.66% and the IR spectra at 1031.92 cm-1, 2945.3 cm-1, 3346.5 cm-1.

Abstract

This research aims for developing immune-boosting products necessary. The active ingredient in Andrographis paniculate (AP) acts as an immunostimulant which can improve the work of the immune system. The first stage of research was a collection of bioactive compounds from KnapSack database of Kanaya, Dr. Duke's Phytochemical and Ethnobotanical were compiled and selected based on the online pass results of each bioactive compound as an immunomodulator and 10 active compounds were obtained which will be continued. The second stage of research was a docking molecular between whey proteins (β-lactoglobulin and α-lactalbumin) with active compounds from AP and casein (α-Casein, β-Casein, and κ-Casein). The highest binding affinity was obtained for α-Casein with Neoandrographolide at -9.2 Kcal/mol. The results of the complex α-Casein with Neoandrographolide (CC) and α-Casein with Neoandrographolide ultraheat (CCT) support the research, namely to function α-Casein as an encapsulant well as a transporter or drug delivery of Neoandrographolide without changing the conformation of casein and disturbing its function. However, the conformation of casein will change drastically during ultraheat treatment to maintain the conformation and binding with the Neoandrographolide ligand. In addition, it supports the simulation results of single α-Casein at ultraheat temperatures which show conformational stability that is not much different from single α-casein and complexes at physiological temperatures
