摘　　要：婴幼儿食品中蛋白质的质量直接影响着婴幼儿的健康成长。本文论述了目前国内外婴幼儿食品中蛋白质质量的评价方法,主要对数值评价、消化率评价、生物学评价和氨基酸评价4类方法进行对比分析,结果表明:用蛋白质消化率校正的氨基酸记分法(PDCAAS)是各种方法中相对较完善的方法。本研究结果对促进我国婴幼儿食品品质的鉴定、新的食品资源的研究和开发以及婴幼儿合理膳食指导具有重要的意义。Protein quality is critical for the infant food,and it will affect the healthy growth and normal development of infants.The methods of protein quality evaluation of infant food were comprehensively contrastive analyzed,which included Numerical Evaluation,Digestibility Evaluation,Biological evaluation and Amino Evaluation.The resultshowed that the protein digestibility corrected amino acid with a scoring method （PDCAAS） was the best in all methods,and could reflect the intergrated protein quality of the infant food.This is important significance for the infnant food quality evaluating,formula developing and research of infant food.
