Introduction: Burn patients need a high nutritional requirement to increase healing process, especially protein. Catfish flour is one of the foods that are high in protein, and Moringa flour is a food that is high in antioxidants. The purpose of this study was to characterize nutrients from high-protein liquid food formulas containing catfish flour and mori nga leaf flour. Methods: Liquid food formula consists of 45 grams catfish flour, 18 grams Mori nga leaf flour, 24 grams soy flour, 18 grams egg white flour, 48 grams full cream milk, 60 gram skim milk, 7.5 ml catfish oi I, 12 ml olive oil, 44 grams sugar powder, and 2 ml pandan flavoring, and 1.5 grams salt. All powdered ingredients were mixed using a dry mixer. Then during the process, catfish oil, olive oil, and pandan flavor were adsorbed using a sprayer into the powdered ingredients. The chemical characterization that analyzed in instant liquid food formula was proximate analysis and mineral analysis. Results: The resuIts of this study were; the formula of high protein liquid food contains 5.79% wb water content, 4.84% wb ash content, protein 28.25% wb, fat 14.99% wb, copper 35.58 mg/kg wb, selenium 56.56 mcg/1 00gram wb, zinc 3.44 mg/100 wb gram, calcium 1381.22 mg/100 grams wb, and iron 7.38 mg/100 grams wb. Also, this liquid food has an osmolality of 481 mOsmol/kgH2O. Conclusion: The liquid food qualifies as a high protein liquid food to fill the nutrients needed for burn patients.
