Article Abstract
The amino acid sequence dictates protein folding and spatial structure, essential for understanding their behavior. Gelatin, important in industry and biomedicine, demands accurate source authentication due to ethical and dietary concerns. This study explores differentiating and quantifying bovine and pork gelatin using UPLC-QTOF and ATR-FTIR spectroscopy. UPLC-QTOF identified distinct ions for pure bovine (m/z + 962.1471, NRLHFFK) and pork gelatin (m/z + 653.0289, YNEVK) but struggled with mixed gelatins due to protein-protein interactions altering peptide ion profiles. ATR-FTIR was employed to leverage ethanol's differential effects on gelatin's amide bands for quantifying pork gelatin contamination in bovine gelatin. The method showed a strong linear correlation (R = 0.9994) with contamination levels and amide band transmission, with detection and quantification limits of 0.85 and 2.85 mg/100 mg, respectively. It effectively identified pork gelatin in halal candy, with recovery rates from 50.05 % to 103.69 %, highlighting ATR-FTIR's potential for accurate gelatin analysis.

In this study, aligned with the principles of the circular economy and sustainability, novel eugenol@natural zeolite (EG@NZ) and citral@natural zeolite (CT@NZ) nanohybrids were developed. These nanohybrids were successfully incorporated into a pork gelatin (Gel)/glycerol (Gl) composite matrix using an extrusion-compression molding method to produce innovative active packaging films: Gel/Gl/xEG@NZ (where x = 5, 10, and 15%wt.) and Gel/Gl/xCT@NZ (where x = 5 and 10%wt.

Healthcare providers increasingly encounter Muslim patients with unique pharmacological considerations influenced by religious beliefs and practices. Islam, as the world's second-largest religion, includes specific guidelines affecting medication permissibility, particularly regarding alcohol and pork-derived ingredients. This educational guide examines the intersection of Islamic teachings with pharmacotherapy, providing examples of commonly prescribed medications containing alcohol or porcine-derived gelatin from our academic medical center's inpatient and outpatient formulary.

In the context of the circular economy, the valorization of bio-derived waste has become a priority across various production sectors, including food processing and packaging. Gelatin (Gel), a protein which can be recovered from meat industry byproducts, offers a sustainable solution in this regard. In this study, pork-derived gelatin was used to develop novel edible active packaging films, designed for meat products.

The application of gelatin (GEL)-based films in food packaging is limited by poor mechanical strength, high water sensitivity, low gas barrier properties, and lack of antibacterial activity. In this study, dialdehyde starch (DS) and AgNPs-immobilized MXene nanosheets (AgNPs@MXene) were incorporated into GEL to fabricate active packaging films. The strong interfacial interactions and compact structure significantly enhanced the films' physicochemical properties.

The biosynthesis of metal nanoparticles using natural extracts represents a significant advancement in quantitative analysis, as it effectively reduces nanoparticle aggregation, thereby enhancing the precision and dependability of analytical results. However, particle agglomeration of the nanoparticles continues to be a notable hurdle. In this study, for the first time, we addressed this issue by introducing gelatine into the synthesis of biogenic gold nanoparticles (AuNPs).
