近红外光谱技术在蛋白质饲料原料检测及溯源方面的研究进展

Review on application of near infrared spectroscopy in protein feed material detection and traceability

蛋白质饲料原料是我国畜牧业发展的基础,对蛋白质饲料原料的品质进行快速分析具有重要的现实意义。介绍了近红外光谱分析技术的原理及特点,综述了近红外光谱分析技术对蛋白质饲料原料的常规成分(水分、粗蛋白质、粗脂肪、粗纤维、灰分)、微量成分(氨基酸、总磷、维生素)的分析以及掺假溯源和在线监测方面的应用和研究进展,系统分析了近红外光谱分析技术在实际应用中存在的问题及应对措施。

Protein feed material is the foundation of the development of animal husbandry in China.Rapid analysis of the quality of protein feed raw materials has important significance.The principles and characteristics of near-infrared spectroscopy（NIRS）was introduced.Progress and application of NIRS technique for routine analysis of raw ingredients（e.g.moisture,crude protein,crude fat,crude fiber,and ash）,trace components（e.g.amino acids,phosphorus,and vitamins）,adulteration traceability and online monitoring were summarized.Finally,problems and solutions of practical application using NIRS were analyzed systematically.
