Herein, we investigated the feasibility of Fourier Transformed mid Infrared (FTIR) spectroscopy for the prediction of a detailed panel of 17 macro, trace, and environmental elements in bovine milk, using partial least squares regression (PLS) and machine learning approaches. The automatic machine learning significantly outperformed the PLS regression in terms of prediction performances of the mineral elements. For macrominerals, the R2 ranged from 0.59 to 0.78. Promising predictability was achieved for Cu and B (R2 = 0.66 and 0.74, respectively) and more moderate ones for Fe, Mn, Zn, and Al (R2 from 0.48 to 0.58). These results provide a reliable basis for a rapid and cost-effective quantification of these traits, serving as a resource for dairy farmers seeking to enhance the quality of milk production and optimize cheese properties. |  |\n\n1. Introduction  \nBovine milk is a complex food that serves as a valuable source of essential components, each with different biological functions. Nutritionally, it is a rich reserve of essential amino acids, fatty acids, minerals, and vitamins. Moreover, it harbors immunoglobulins, hormones, and various other bioactive compounds (Haug et al., 2007). Even though minerals constitute only a small proportion (0.7%) of milk components (Kaufmann & Hagemeister, 1987), they are essential to human health as they contribute to different physiological functions such as the skeletal tissue formation, bone maintenance, biosynthesis of specific molecules, acid-base regulation and nerve impulse transmission (Stergiadis et al., 2021). In addition, some minerals play an important role in determining milk technological properties. Specifically, Ca and P serves as fundamental components of casein micelles, directly impacting both milk coagulation and final consistency of coagulum (Gustavsson et al., 2014; Stocco et al., 2021).  \nFurthermore, elements such as Na and K have proven to be potential indicators of udder health as both their concentration is influenced by the modified permeability of blood-milk membrane induced by mastitis (Khatun et al., 2019). The concentration of milk minerals is dependent  \nalso on different factors, like the animals’ feeding systems and environmental features. Among milk minerals, iodine has been poorly described given the difficulty in determining its actual content in milk (Niero et al., 2020), which is influenced by different aspects such as the use of teat dipping sanitizers, differences in farming system and dietary supplements.  \nMilk mineral elements are conventionally quantified through analytical techniques such as mass spectrometry or inductively coupled plasma - optical emission spectrometry (ICP - OES) (Di et al., 2009; Soyeurt et al., 2009). However, these methods are time consuming, expensive and require expert personnel, and therefore unsuitable for large scale analysis.  \nTherefore, finding fast and affordable methods to measure the milk mineral profile might be beneficial for the dairy sector, considering the impli","cbCaioIuW0CKkSGt","https://ap.wps.com/l/cbCaioIuW0CKkSGt","pdf",8074207,1,11,"English","en",105,"#
