| 摘 要： | 淀粉糊化度是评价颗粒饲料加工质量的重要指标,直接影响畜禽吸收利用饲料中能量物质的效率,进而影响饲料的转化效率和畜禽生长状态。该文建立了颗粒饲料淀粉糊化度的两种快速检测方法,其中近红外光谱分析方法(NIRS)检测淀粉糊化度的定标和验证模型的决定系数(R2)分别为0.8759和0.9608;而快速黏度分析法(RVA)预测淀粉糊化度的定标和验证模型的决定系数分别为0.8025和0.8746。试验结果表明近红外光谱分析技术和快速黏度分析法均可快速且较准确地预测颗粒饲料的淀粉糊化度,在一定程度上能较好地满足实时监测饲料加工过程淀粉糊化程度、实现颗粒饲料精细加工的需要。

| Abstract: | Starch gelatinization degree is one of the most important indexes for feedstuff processing,which affects the utilization efficiency of energy in feedstuffs,digestibility coefficients of feedstuffs and animal performance.In this study,two rapid quantification methods for starch gelatinization degree were selected.The determination coefficients of calibration and validation models of near infrared reflectance spectroscopy(NIRS)were 0.8759 and 0.9608,respectively,while those of rapid viscosity analysis(RVA)were 0.8025 and 0.8746,respectively.Those results show that NIRS and RVA methods can predict gelatinization degree of pellet feedstuff starch rapidly and accurately.And they also can be used in on-line determining the starch gelatinization degree in feedstuff industry,and the quality level of pellet feedstuff processing can be improved. |
