Determining Weight and Moisture Properties of Sound and Fusarium-Damaged Single Wheat Kernels by Near-Infrared Spectroscopy
Determining Weight Moisture Properties Sound and Fusarium-Damaged Single Wheat Kernels Near-Infrared Spectroscopy
2014/5/23
Single kernel moisture content (MC) is important in the measurement of other quality traits in single kernels because many traits are expressed on a dry weight basis. MC also affects viability, storag...
基于近红外光谱分析法的奶粉品质快速检测（Quick Determination Method of Milk Powder Quality by Near-infrared Spectroscopy）
奶粉 品质检测 近红外光谱
2009/8/11
选择11个品牌的10多种配方奶粉，共80个样品，使用PDA型近红外光谱仪采集奶粉漫反射光谱，波长范围1089～2219nm。对光谱进行了SNV、软阈小波消噪及一阶微分预处理，通过比较主成分在不同波长上的权重分布，选择不同波段建立校正模型和进行预测精度分析。结果表明，奶粉的蛋白质和脂肪的近红外光谱信息主要分布于1100～1400nm和1800～2200nm波段内，采用小波消除原始光谱的噪声能提高校正...
Simultaneous Determination of Moisture, Protein and Fat in Fish Meal Using Near-Infrared Spectroscopy

Near-Infrared Spectroscopy for Dairy Management: Measurement of Unhomogenized Milk Composition
unhomogenized milk composition nearinfrared spectroscopy
2008/3/31
The potential of near-infrared spectroscopy to measure fat, total protein, and lactose contents of unhomogenized milk was studied for use in dairy management, as a new tool for on-line milk analysis i...
In this work, the major components (total solids, fat, protein, casein, urea nitrogen, lactose, and somatic cells) were determined in cow milk by near-infrared spectroscopy. Fifty calibration samples ...
