Yogurt and whey beverages available in Brazilian market: Mineral and trace contents, daily intake and statistical differentiation. Food Res Int 2019; 119:709-714. [PMID: 30884707 DOI: 10.1016/j.foodres.2018.10.050] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2018] [Revised: 10/01/2018] [Accepted: 10/15/2018] [Indexed: 10/28/2022]
Abstract
Mineral and trace elements (Ca, Fe, K, Mg, Na, Pb, Cd, Cr, Cu, and Mn) in commercial strawberry-flavored yogurts and fermented whey beverages in Brazil were investigated. K, Ca, Na, Mg and Fe concentrations ranged from 1.6 to 1.4, 1.4 to 1.1, 0.74 to 0.68, 0.16 to 0.11, and 0.01 mg g-1 for yogurts and whey beverages, respectively. Similar concentrations of the minerals were observed for both products, except Mg (0.16 mg g-1 in yogurts and 0.11 mg g-1 in whey beverages). Cd, Cr, Cu, Mn, and Pb was found below the detection limit (21.4 to 94.1 μg g-1), demonstrating safety levels for consumption. Regarding the mineral daily intake, consumption of 100 g of the product has relevance for calcium in infants (>40%) and children between 4 and 8 years (>13%), and a greater contribution of yogurt over whey beverage was observed. PLSDA model suggested that Mg analytical determination should be performed to ensure the identity of the product.

Abstract
Insoluble calcium phosphate particles, such as hydroxyapatite (HA), are often used in calcium-fortified milks as they are considered to be chemically unreactive. However, this study showed that there was an interaction between the casein micelles in milk and HA particles. The caseins in milk were shown to bind to the HA particles, with the relative proportions of bound β-casein, αS-casein, and κ-casein different from the proportions of the individual caseins present in milk. Transmission electron microscopy showed no evidence of intact casein micelles on the surface of the HA particles, which suggested that the casein micelles dissociated either before or during binding. The HA particles behaved as ion chelators, with the ability to bind the ions contained in the milk serum phase. Consequently, the depletion of the serum minerals disrupted the milk mineral equilibrium, resulting in dissociation of the casein micelles in milk.

Abstract
Acidification is fundamental for the processing of milk into cheeses, caseins, and fermented dairy products. It is established that a pH decrease changes the ionic equilibria of milk, inducing the solubilization of micellar calcium phosphate. This study aimed to present a theoretical model calculating ionic equilibria in milk as a function of pH. From the pH and total concentrations of minerals and caseins, the model calculated the concentrations of all ionic species and their partition between micellar and aqueous phases of milk. As the pH decreased, the minerals present in the micellar phase were gradually displaced into the aqueous phase. The calculated concentrations of minerals were in a good agreement with the experimental ones determined from acidified milk. A very satisfactory accuracy of the calculations, estimated by a root-mean-square error (RMSE) value of 5% for Ca and P(i) and a slope of the plot close to a unit, was obtained. The model is proposed for the simulation of ionic equilibria and the partition of salts between the aqueous and micellar phases of milk and dairy formulations during acidification.
