Abstract for the dataset: Near-infrared (NIR) spectra were acquired non-destructively from beef patties enriched with varying levels of plant-based proteins. Spectral data were registered using two NIR instruments: first, a hand-held point-based microNIR spectrometer sensitive in the 908.1 - 1676.2 nm wavelength range, and secondly, a hyperspectral imaging (HSI) system covering the 900 - 1700 nm spectral range. The complete dataset is composed of 240 patties prepared from Spanish Ternera de Navarra beef, including 60 pure-beef control samples and 180 enriched patties. The latter were formulated with pea (n = 60), soybean (n = 60) or chickpea (n = 60) proteins. For each protein type six inclusion levels (1, 2, 3, 4, 5, 6% w/w) were formulated, each with 10 independent replicates. 2.

List of all files included in the dataset (Burger_Dataset): File name: HSI Description: It contains the spectral information recorded with a hyperspectral imaging camera in the NIR range (900 - 1700 nm). The folders "250122", "250124", "250128", "250130", "250131_01", "250131_02", "250204", and "250205" correspond to each measuring day. Inside, the folder contains the black-and-white reference images and the 3D hypercubes without being normalized. The folder "cubes" contains the normalized hypercubes. The folder "gtruth" contains the mask of each sample. The folder "meanSpectra" contains the mean spectra calculated for every sample. The folder "unfolded" contained the unfolded hypercubes to a 2D matrix. File name: microNIR Description: It contains the file "All_data.csv", which includes the absorbance spectra of the 5 replicates recorded for every sample. 2. File format: .mat; .png; .csv
