Trace and rare earth elements determination in milk whey from the Veneto region, Italy

Abstract

, Y) in whey samples from cow and goat milk by inductively coupled plasma mass spectrometry and inductively coupled plasma-sector field mass spectrometry. A total of 261 milk whey samples were collected from four locations in the Veneto region of northeastern (NE) Italy. These samples contain a wide range concentration of 17 trace elements (0.06-1530 μg kg − 1) and 14 rare earth elements (0.16-28.2 ng kg − 1) in whey samples, but do not reach toxic concentrations. Elemental fingerprinting of trace and rare earth elements in cow and goat milk whey provide information on the dairy quality and, as they reflect the local environmental conditions, result in an excellent indicator of their geographical origin.

Biochemical, dielectric and surface characteristics of freeze-dried bovine colostrum whey powder

“…From the results ( Table 3 ), it was found that the concentration of essential trace minerals in BCWP was in the order of sodium > calcium > magnesium > iron > selenium for trace elements. Furthermore, metals are non-biodegradable, which accumulate in the food chain through biotransformation ( Tedesco et al, 2021 ). Several authors ( Rahimi, 2013 , Temiz and Soylu, 2012 ) reported the occurrence of heavy elements (lead, mercury and cadmium) in whole milk or milk-based products.…”

“…Therefore, BCWP was analysed for heavy metals and the obtained results were tabulated in Table 3 . The level of heavy metals, Pb, As and Cd in milk-based whey of cows from the Veneto region, Italy was reported as 0.0002 ± 0.0001, 0.0013 ± 0.0005, 0.0062 ± 0.0010 mg kg −1 respectively ( Tedesco et al, 2021 ). The level of heavy metals (Mn, Cr, Ni, Cd, Pb, Hg, As) in sweet/acid concentrated whey was < 0.10 (ppm) ( Alsaed et al, 2013 ).…”

Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), a Useful Tool in Authenticity of Agricultural Products’ and Foods’ Origin

“…), dietary habits and supplements. In similar studies, Tedesco et al (2021) [ 78 ], and Aceto et al (2017) [ 79 ] investigated the role of trace and rare earth elements in milk samples, throughout the production chain, from various regions of Italy. It was observed that the concentration of lanthanides remains nearly constant during the milk production and therefore were classified as suitable tracers.…”

Development, Validation and Application of an ICP-SFMS Method for the Determination of Metals in Protein Powder Samples, Sourced in Ireland, with Risk Assessment for Irish Consumers

“…Given the potential implications to human health through excessive consumption of these products, it is important to develop sensitive and reliable analytical methods that can accurately identify and quantify element levels in protein powder products to ensure that they are safe for human consumption. Inductively coupled plasma-sector field mass spectrometry (ICP-SFMS) is a technique that offers the selectivity and sensitivity necessary to meet the analytical challenges of both simple and complex matrices [ 1 , 20 ], and it has been deployed successfully in recent years for the analysis of milk products [ 2 , 21 ]. Thus, the aim of this study is to develop a reliable ICP-SFMS method to assess the concentrations of essential/therapeutic elements in protein powder samples, as well as to investigate the possible potential risks to Irish consumers from exposure to these substances.…”

“…As can be seen below in Table 1 (adapted from Ring et al, 2016 [1]), the human body is comprised of these elements with many playing critical roles in metabolic processes, while others can cause negative side effects at certain concentrations. Balanced nutrition is therefore an essential aspect of maintaining health, as it allows our bodies to grow, repair and function and promotes overall health and wellbeing [2].…”
