Goat skin with lactobacillus plantarum 1UHCC pretreatment and acetic acid are expected to be able to explore goat skin gelatin at different ages so that it has high quality and health benefits as an antioxidant. The quality of the resulting goat skin gelatin is seen from the antioxidant content using the Diphenylpicrylhydrazyl (DPPH) method, protein content, fat content, water content, Fourier Transform Infrared Spectroscopy (FTIR). The combination of different goat ages with L. plantarum pretreatment gives a higher antioxidant effect. Protein and fat levels are physical properties of gelatin that affect antioxidant activity as well as changes in functional groups of gelatin using Fourier Transform Infrared Spectroscopy (FTIR) detected four amide areas namely amide group A (3566.38 - 2854.65 cm-1), amide group I (2358.94 - 2126.56 cm-1), amide group II (1452, 40 cm-1) and amide III group 1080.14 - 669.30 cm-1. The existence of hydrogen bonds allows the formation of free radical bonds in gelatin. Conclusion, L. plantarum 1 uhcc pretrearment at 1 year old goat skin has the highest antioxidant content. Likewise, the chemical properties of goat skin gelatin are strongly related to the antioxidant activity of gelatin.
