    Gelatin is commonly used in different commercial products. The font of gelatin is from porcine or bovine. Gelatin is much similar in illustration of composition, physicochemical properties and arrangement of Amino acids yet having different source. Due to these similarities, differentiation to find source is become challenging. In this present work, the sources of gelatin were find out in a very economical but simple method to ensure Halal food products. This examination was done to extricate and portray gelatin from various business products. Then treated with 1% NH4HCO3 having pH 8.0 at 25℃ for 24 hours. The gelatins were treated by trypsin enzyme, and the succeeding peptides were evaluated by HPLC–MS. The marker peptides specific for bovine like and porcine were efficiently gotten in the split with bull like and porcine gelatin. Comparable examinations exhibited that specific peptide marker show the presence of porcine gelatin. It was noticed that proline hydro-xylation was the main factor impacting the peptide ID. For instance, GPPGSAGSPGK and GPPGSAGAPGK perceived in prepared bull like and porcine gelatin. The outcomes demonstrate that identification of peptides in the processed gelatin test utilizing High performance liquid chromatography along with mass spectrometry is a viable strategy to separate among cow-like and porcine gelatin. Skyline software was used to interpret the graphs. TIC and MRM studies was done to interpret the data. We have discovered certain peptide markers which are valuable to separate porcine and ox-like gelatin. Sample no.6 was the focal point of concern since it shows the peptide marker of both porcine and ox-like peptide. Remaining examples indicated whether the source is ox-like or porcine.
