As described in “ Use of Fourier transform infrared spectroscopy and partial least squares regression for the detection of adulteration of strawberry purees“ Holland JK, Kemsley EK, Wilson RH. Obtained using Fourier transform infrared (FTIR) spectroscopy with attenuated total reflectance (ATR) sampling.
983 Mid-infrared (MIR) spectra of fresh fruit purees: strawberry (authentic samples) and non-strawberry (adulterated strawberries and other fruits). Users can explore, filter, visualize, and export data in a variety of formats, including Excel, JSON, XML, as well as access and build with these datasets via API.The following datasets can also be downloaded below as ‘zipped’ folders. FTIR Spectra of Red Wines – 37 red wines of two varieties, sub-sampled in triplicate A data set is a collection of responses or observations from a sample or entire population.FTIR Spectral Library – illustrative examples of a variety of foods and ingredients.Benchtop NMR spectra of ‘Arabica’ ground roast coffees: a retail survey (includes several suspected adulterated samples).Please visit our GitHub page QIBChemometrics for secure download of all the latest data repositories, including:
