ABSTRACT
Objective To compare delivery accuracy and precision of nutrients as well as physicochemical property between self-made homogenate diet an d commercial dairy based enteral nutrition product and investigate the clinical significances.Methods GB methods were used to examine and analyze the nutrients in self-made homogenate diet and commercial dairy based protein product.Results Self-made homogenate diet exhibited high viscosity (20,000±2121.32) cps because of high water content.The actual values for macronutrients and energy were all lower than 10％ of designed values.The actual values for lipid soluble vitamins A and E were only 49.32％ and 56.47％ of designed values,while the actual values for water soluble vitamins B1,B6 and C were all very low that were close to or lower than detection levels.All minerals,except for potassium were lower than the designed values,wherein iron was only 25.16％ of designed value.For commercial enteral nutrition product,the actual contents of energy,macro-and micro-nutrients including vitamins and minerals were all higher than the designed values and the difference between the contents of minerals and its designed values were controlled within deviation range (5％ ～ 10％).Conclusion For vitamins and minerals in self-made homogenate diet,non-linear correlation was identified between the testing value and designed value.Commercial enteral nutrition product can provide more accurate nutrient level to reach the designed value,and has better flexibility on individual nutrient fortification.
