    The purpose of my research is to find the most favourable maize hybrids for bioethanol-production feedstock, using the so called „NIT”, near infrared spectroscopy method in the analysis of the inner contents especially of starch content. The other goal of my analysis is to reflect on how the effects of the most important growing factors – such as irrigation and the use of different dose fertilizers – contribute to the maize hybrids starch content.

    Near-infrared spectroscopy has many advantages that make it a widely used analitical method in the different areas, like agricultural and food industry as well. In wheat quality control rheological characteristics of dough made from wheat flour are as important as physical and chemical properties too. In this work we examined rheological properties of wheat flour samples by alveograph, and spectral data of the same samples were collected by FOSS Infratec 1241 instrument. Modified partial least squares analyses on NIR spectra were developed for two alveograph parameter (P/L és W) to get calibration equations.

  • Quality analysis of the near-infrared spectra of wheat samples

    The near infrared spectroscopy is widely used in the different industries as a rapid, non-invasive analitical tool. It is suitable for identification, qualification and quantitative analysis as well. As this technique is indirect, to make accurate calibration equations we need a proper sample population. Before the quantitaive analysis, developing calibiration modells we have to collect and examine the spectra. In our study we examined wheat samples with known origins to find if there is any effect of the growing area on the NIR spectra.
