Backgrounds & Purposes: Enteral nutrition (EN) is crucial for patients that cannot feed orally. Different mixtures have been used for EN and several advantages and limitations have been mentioned for each. Home-made, hospital blenderized liquids have long been used in clinical setting. Hospital prepared formulas (HPF) are still preferred in Iran. There is no standard method for preparing these feedings. The purpose of this study was to analyze the nutritional quality and viscosity of standard hospital prepared formula in Kamyab hospital.
 Materials & Methods: This was a descriptive study which analyzed macronutrients, osmolality and viscosity of standard hospital prepared formula samples based on exchange list. To compare mean values and standard deviation one sample t test was used.
Results: Caloric density of samples ranged from 77-96 kcal/100 g and the percentages of total weight for carbohydrate were 10.7, 11.3, and 6.5; for Protein and fat were 4.1 and 3.8 g/100 ml. The average variability of the viscosity was 35-110 centipoise, and osmolality  ranged from 145-345 mosm/kg.
Conclusion: The results showed that exchange list was reliable. This standard formula had an acceptable level of macronutrient and if it prepared like the recipe, it would supply energy requirement of patients.
