摘　　要：目的探讨一种典型自制匀浆膳和一种工业化肠内营养制剂的营养素准确性、精确性及物理化学性的差异及在临床治疗中的意义。方法采用GB方法对自制整蛋白匀浆膳和工业化生产乳基整蛋白配方中的营养素进行检测和统计分析。结果自制匀浆膳含水量较高,黏度达到(20000±2121.32)cps;宏量营养素及能量实际测定值均略低于设计值的10%;维生素中,实测脂溶性维生素A和E只占设计值的49.32%和56.47%,而水溶性维生素B1、B6和C含量非常低,接近或已低于检测线;矿物质中除钾外其他均低于设计值,其中铁只占设计值的25.16%.工业化肠内营养制剂中能量、宏量营养素、微量营养素(维生素和矿物质)的含量均高于设计值且矿物质含量与设计值的差异控制在方法偏差值范围内(5%-10%).结论匀浆膳中维生素与矿物质与设计值的偏差为非线性关系,因此工业化肠内营养制剂可以提供更精确的营养素水平来达到设计值要求,在单一营养素的强化也更具有灵活性。Objective To compare delivery accuracy and precision of nutrients as well as physico-chemical property between self-made homogenate diet and 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.
