Abstract

This study aims to evaluate the potential of red dragon fruit skin pectin to be used as a polymer compared with commercial pectin in the quercetin microsphere. Microspheres were made using the ionic gelation technique. Ten formulas were created, utilizing pectin from red dragon skin extracted with oxalic acid (OA75), citric acid (CA75), acetic acid (AA75), and commercial pectin at 1% and 1.5% concentrations. A gel permeation chromatography test (GPC) was performed to evaluate pectin’s molecule weight. Parameters were assessed, including yield, moisture content (MC), Carr’s Index, Hausner ratio, swelling index, Fourier Transform Infrared Spectroscopy (FTIR), particle size, polydispersity index (PDI), drug loading (DL), encapsulation efficiency (EE), Scanning Electron Microscope (SEM), in vitro drug release, accelerated stability test at a temperature of 40±2oC and RH 75±5% for 3 months and thermal stability test in the form of DSC and XRD at the same temperature and humidity for 9 months, digestion resistance with incubation in artificial stomach and intestinal solution for 4 hours continued with cytotoxicity test on HeLa cells with MTT Assays. Results of FTIR indicate a strong interaction between quercetin and pectin in forming a stable microsphere structure; SEM showed the spheres morphologically. The kinetics of quercetin release from microspheres was the Korsmeyer-Peppas model. DL and EE had no significant differences for 3 months and no significant changes in the glass transition in the DSC test during testing until month 9. The FF formulation (1.5% AA75) had the highest cytotoxic activity against HeLa cells and a high Selectivity Index.

Abstract

Cosmetic trends in Indonesia are on the rise, particularly for facial serum products. However, most of these products lack halal certification, posing an important concern for Muslim consumers due to the potential use of haram substances, such as pork gelatin. This study seeks to identify the source of gelatin in serum products using the Fourier Transform Infrared (FTIR) spectroscopy and chemometric analysis. The samples used in this study include a reference facial serum formulated with pure bovine and porcine gelatin concentrations in the ratios of 1:0, 8:2, 5:5, 2:8, and 0:1, three hydrolyzed collagen serums that are not yet labeled halal and available on Shopee, and one serum that is labeled halal. The method used was FTIR combined with PLS chemometrics and PCA. The isolation of facial serum gelatin was performed using acetone at -20oC, followed by analysis via FTIR at wave numbers ranging from 4000 to 400 cm-1. FTIR results indicated the presence of functional groups in gelatin constituents, including C O, N H, C N, and C H aliphatic. The wavelengths employed for PLS and PCA analysis ranged from 1631 to 1430 cm-1. Calibration results showed R2=0.9936 and RMSEC=3.0445%. Internal validation yielded RMSECV=0.1674% and R2=0.9994 whilst external validation yielded RMSEP=0.9981% and R2=0.9910. Lastly, PCA analysis revealed that one halal-labeled serum sample contained bovine gelatin, whereas the three examined commercial serums were free from both pork and bovine gelatin.
