大豆浓缩蛋白中蛋白质和水分的检测引言:在豆类加工工业中,近红外光谱(NIR)是一种公认的品质控制工具。
常规NIR分析检验豆粕、豆壳和豆的“白片”,可以监测磨粉和榨油的过程。
另外一种大豆加工企业感兴趣的豆类产品是大豆浓缩蛋白(SPC)。
除去可溶性碳水化合物时,将大豆蛋白固定在脱脂豆粕上,制成SPC。
产品的蛋白质含量大约为70%。
利用此工艺,1000kg的脱脂豆饼可以产生约750kg的SPC。
SPC被用于制作焙烤食品、谷物早餐和一些肉制品。
SPC对肉和家禽的功能是提高保留的水分和脂肪,也可以通过添加更多的蛋白质增加其营养价值。
SPC易消化,非常适合儿童、孕妇和老人。
也可以用于宠物食品和作为小牛和猪的代乳食品。
本研究的目的是开发NIR在分析大豆浓缩蛋白中蛋白质和水分的应用。
这被大豆加工企业用于监测碳水化合物的分离和蛋白质浓缩。
SPC的干基蛋白含量不能低于65%。
大豆加工企业已经有能力使用NIR监控SPC的生产,保证产品的品质。
试验设计:该实验在美国一家主要的大豆加工公司协助下进行。
SPC样品由工作人员收集,带到湿化学室分析。
每一个样品都使用带1mm屏幕的Udy Cyclone粉碎机反复研磨。
实验室收集和分析了636个样品,蛋白含量使用杜马斯燃烧法测定。
水分含量使用快速烘箱水分测定法,实验室收集和分析197个样品。
为了建立标准,收集近红外光谱范围,每一个样品都放到金属杯里,使用Unity Scientific SpectraStar 2400进行分析。
图1和图2显示了本研究中SPC 的浓度分布和范围。

You can import arbitrary waveforms from data files or draw them using the built-in AWG editor.Spectrum analyzerWith the click of a button, you can open a new window to display a spectrum plot of selected channels. The spectrum analyzer allowsColor persistence modesSee old and new data superimposed, with new data in a brightercolor or shade. This makes it easy to see glitches and dropouts and to estimate their relative frequency. Choose between analog persistence and digital color, or create a custom display mode.High-speed data acquisitionThe drivers and software development kit supplied allow you towrite your own software or interface to popular third-party software packages. If the 1 gigasample record length of the PicoScope 6404B Spectrum analyzerArbitrary waveform generatorPicoScope performance and reliabilityWith 20 years’ experience in the test and measurement industry, we know what’s important in a new oscilloscope. The PicoScope 6000 Series scopes have the best bandwidth, sampling rate and memory depth of any USB oscilloscopes. These features are backed up by advanced software developed with the help of feedback from our customers.High bandwidth, high sampling rateWith a 250 MHz to 500 MHz analog bandwidth complemented by a real-time sampling rate of 5 GS/s, the PicoScope 6000 Series scopes can display single-shot pulses with 200 ps time resolution. ETS mode boosts the maximum sampling rate to 50 GS/s, giving higher timing resolution for repetitive signals.Huge buffer memoryThe PicoScope 6000 Series gives you the deepest buffer memory available as standard on any oscilloscope. Other oscilloscopes have high maximum sampling rates, but without deep memory they cannot sustain these rates on long timebases. The 1-gigasample buffer on the PicoScope 6404B allows it to capture at 5 GS/s down to 20 ms/div for a total duration of 200 ms. To help manage all this two zoom methods. There are zoom buttons as well as an overview window that lets you zoom and reposition the display by simply dragging with the mouse.Advanced triggersAs well as the standard range of triggers found on most oscilloscopes, the PicoScope 6000 Series has a built-in set of advanced triggers to help you capture the data you need.All triggering is digital, resulting in high threshold resolution and excellent waveform stability.Custom probe settingsThe custom probes feature allows you to correct for gain, attenuation, offsets and nonlinearities in special probes, or toconvert to different units of measurement. Definitions for standard Pico-supplied probes are built in, but you can also save your own definitions to disk for later use.Rapid triggeringThe PicoScope 6000 Series contains special triggering hardware to minimise the time between captures. This enables you to collect waveforms at intervals of 1 μs or less when using a short timebase, improving your chances of spotting an infrequent glitch.Deep memory allows you to zoom in... and in... and in6000 Color persistence modesSerial data decoding:CAN • LIN • UART • SPI • I 2CThe PicoScope 6000 Series oscilloscopes are well-suited to serial decoding, with a deep memory buffer that allows them to collect long, uninterrupted sequences of data. This allows the capture of thousands of frames or packets of data over several seconds. The scopes can decode up to four buses simultaneously with independent protocol selection for each input channel.PicoScope displays the decoded data in the format of your choice: “in view”, “in window”, or both at once.“In view” format shows the decoded data beneath the waveformon a common time axis, with error frames marked in red. You can zoom in on these frames to look for noise or distortion on the waveform.“In window” format shows a list of the decoded frames, includingthe data and all flags and identifiers. You can set up filteringconditions to display only the frames you are interested in, search for frames with specified properties, or define a start pattern that the program will wait for before it lists the data.Mask limit testingThis feature is designed for production and debugging environments.Capture a signal from a known working system, and PicoScope will draw a mask around it with your specified tolerance. Connect the system under test, and PicoScope will highlight any parts of thewaveform that fall outside the mask area. The highlighted details persist on the display, allowing the scope to catch intermittent glitches while you work on something else. The measurements window counts the number of failures, and can display other measurements and statistics at the same time.The numerical and graphical mask editors (both shown above) can be used separately or in combination, allowing you to enter accurate mask specifications or modify existing masks. You can import and export masks as files.Digital low-pass filteringEach input channel has its owndigital low-pass filter withindependently adjustable cut-off frequency from 1 Hz to the full Accessories includedInstruction manualSolid tip 0.5 mmCoding rings, 3 x 4 colors Ground lead 15 cm TA133• Instruction manual • Solid tip 0.5 mm• Coding rings, 3 x 4 colors • Ground lead 15 cm Serial data decodingMask limit testingmovable axes: The vertical axes can be dragged up and down.
