“…Mineralized solutions were transferred to a 10 mL volumetric flask and diluted with ultrapure water for the measurements of trace elements. Mineralized solutions were further diluted 1:10 with ultrapure water for the measurement of macro minerals and Zn [15,16]. Mineralization solution for feedstuffs was made of 0.15 g of ground samples, 3.5 mL of HNO 3 (65%) (Suprapur quality, Merck), and 3.5 mL of H 2 O 2 (30%; Suprapur quality, Merck).…”

Aim of this study was to evaluate the differences in Ca, P, K, Na, Mg, Zn, Fe, Cu, Mn, Se, Mo, Co, Li, B, Ti, Rb, and Sr concentrations in milk from buffaloes and cows reared in the same farm in Mediterranean areas and fed diets including the same ingredients. Individual milk samples were obtained from 32 Mediterranean buffaloes and 29 Italian Friesian cows and samples of milk, dietary ingredients and drinking water were analyzed for the investigated chemical elements by inductively coupled plasma-mass spectrometry. Data about milk element concentrations were processed by one-way analysis of variance. Buffalo milk contains higher concentrations of Ca, P, Mg, Zn, Fe, Cu, B, Ti, and Sr, and lower concentrations of K, Na, Mo, Li, and Rb compared to cow milk, whereas milk from both species contains similar concentrations of Mn, Se, and Co. The concentrations of the investigated elements in the diet were similar for both species and the differences observed between buffalo and cow milk were not dependent on environmental factors.

“…Donkey milk was the subject of a study by Fantuz et al 234 The team investigated the distribution of 14 elements (B, Cd, Co, Cr, Cu, Li, Mn, Mo, Pb, Rb, Se, Sr and Ti) in the fat, casein, whey and aqueous phases of the milk. Samples were separated by ultra-centrifugation and ultra-filtration to obtain the 4 phases that then underwent MAD followed by ICP-MS.…”

“…To our knowledge, no studies have investigated the influence of caseins on Se bioaccessibility. What is known is that Se in milk and dairy products is strongly associated with both caseins and whey proteins [74,75]. In addition, the presence of protein ingredients has also been seen to increase the Se content in food mixtures [76] and Se could be absorbed better from a high protein diet or when protein isolates are presented [77,78].…”

“…Regarding Se, the explanation for the considerable increase in its bioaccessibility upon the presence of lactalbumin could be similar to that provided above for caseins. Protein ingredients are the main dietary source of Se and also could promote its bioavailability [74][75][76].…”

The objective of this work was to study the influence of three dietary fibre fractions (pectin, gum arabic and cellulose) and three protein fractions (casein, lactalbumin and soy) on the trace element bioaccessibility (Fe, Mn, Ni, Se and Zn) of turnip tops (B. rapa subsp. Rapa) growing under Mediterranean conditions. Then, it aimed to promote the use of this vegetable not only for direct fresh consumption but also as a main ingredient in the development of food mixtures. The results showed that soluble fibre fractions, such as pectin and gum arabic, can enhance the bioaccessibility of trace elements, such as Fe, Mn, Se and Zn. This effect was not proved for cellulose (an insoluble fibre fraction), in which, at best, no bioaccessibility effect was observed. Regarding the protein fractions, with the exception of Se, caseins and lactalbumin had a neutral effect on improving the trace element bioaccessibility. This did not hold true for soy protein, in which a considerable improvement in the bioaccessibility of Fe, Mn, Se and Zn was determined.
