Total nitrogen determination is the standard analytical technique for quality control, which is incapable of distinguishing between protein nitrogen and nitrogen from non-protein sources. Three benchtops and one handheld near-infrared spectrometer (NIRS) with different signal processing techniques (grating, Fourier transform, and MEM—micro-electro-mechanical system) were compared with detect adulteration in protein powders at low concentration levels. Whey, beef, and pea protein powders were mixed with a different combination and concentration of high nitrogen content compounds—namely melamine, urea, taurine, and glycine—resulting in a total of 819 samples. NIRS, combined with chemometric tools and various spectral preprocessing techniques, was used to predict adulterant concentrations, while the limit of detection (LOD) and limit of quantification (LOQ) were also assessed to further evaluate instrument performance. Out of all devices and measurement methods compared, the most accurate predictive models were built based on the dataset acquired with a grating benchtop spectrophotometer, reaching R2P values of 0.96 and proximating the 0.1% LOD for melamine and urea. Results imply the possibility of using NIRS combined with chemometrics as a generalized quality control tool for protein powders.}, year = {2024}, eissn = {1420-3049}, orcid-numbers = {Bázár, György/0000-0001-9829-4366; Pollner, Bernhard/0000-0002-3759-4450; Fodor, Marietta/0000-0001-8647-3201} } @article{MTMT:34376486, title = {Utilizing Haematococcus Pluvialis to Simulate Animal Meat Color in High-Moisture Meat Analogues: Texture Quality and Color Stability}, url = {https://m2.mtmt.hu/api/publication/34376486}, author = {Huang, Zehua and Liu, Ying and An, Hongzhou and Kovács, Zoltán and Abddollahi, Mehdi and Sun, Zhongke and Zhang, Gaoyang and Li, Chengwei}, doi = {10.1016/j.foodres.2023.113685}, journal-iso = {FOOD RES INT}, journal = {FOOD RESEARCH INTERNATIONAL}, volume = {175}, unique-id = {34376486}, issn = {0963-9969}, year = {2024}, eissn = {1873-7145} } @article{MTMT:34224104, title = {Aquaphotomics based screening of tomato powder extracts reveals susceptibility to bulking and coloring agents}, url = {https://m2.mtmt.hu/api/publication/34224104}, author = {Aouadi, Balkis and Laryea, Damian and Aguinaga Bósquez, Juan Pablo and Majadi, Mariem and Kertész, István and Bodor, Zsanett and Zinia Zaukuu, John-Lewis and Kovács, Zoltán}, doi = {10.1016/j.foodcont.2023.110163}, journal-iso = {FOOD CONTROL}, journal = {FOOD CONTROL}, volume = {157}, unique-id = {34224104}, issn = {0956-7135}, year = {2024}, eissn = {1873-7129}, orcid-numbers = {Aouadi, Balkis/0000-0003-3997-397X; Kertész, István/0000-0001-8336-865X; Bodor, Zsanett/0000-0002-1577-2973; Zinia Zaukuu, John-Lewis/0000-0002-2058-4416; Kovács, Zoltán/0000-0003-0641-8830} } @{MTMT:33319149, title = {Analytical Methods for Nutritional Composition of Honey}, url = {https://m2.mtmt.hu/api/publication/33319149}, author = {Bodor, Zsanett and Zaukuu, John-Lewis Zinia and Aouadi, Balkis and Kovács, Zoltán and Benedek, Csilla}, booktitle = {Sustainable and Functional Foods from Plants}, unique-id = {33319149}, year = {2024}, orcid-numbers = {Benedek, Csilla/0000-0001-5656-6976} } @{MTMT:33319073, title = {Detection Methods of Adulteration in Natural Foods}, url = {https://m2.mtmt.hu/api/publication/33319073}, author = {Zaukuu, John-Lewis Zinia and Bodor, Zsanett and Vitális, Flóra and Kovács, Zoltán}, booktitle = {Sustainable and Functional Foods from Plants}, unique-id = {33319073}, year = {2024} } @book{MTMT:33111782, title = {Sustainable and Functional Foods from Plants.
