In this study, the concentrations of non-essential elements during the manufacture of torba yoghurt were determined. Daily intakes of elements were also estimated. Quantitative determinations of these elements [aluminum Al , antimony Sb , arsenic As , boron B , beryllium Be , cadmium Cd , nickel Ni , lead Pb , silver Ag , titanium Ti , thallium Tl and vanadium V ] were performed by Varian Vista-MPX simultaneous inductively coupled plasma optical emission spectrometer ICP-OES . For the daily intake evaluation, the weighted average for each element in milk, yoghurt and torba yoghurt was calculated, and then multiplied by the respective consumption rate. Boron was the most abundant element in all samples. Except for Be and V, the concentrations of the other elements were significantly varied during torba yoghurt-making. The total daily intakes of Al, As, Sb, Be, B, Cd, Pb, Ni, Ag, TI, Ti and V from milk and yoghurt were estimated as 0.84, 0.33, 0.28, 7.16x10-3, 3.39, 0.023, 0.44, 0.31, 0.054, 0.974, 0.032 and 0.155 mg, respectively

Çalışmada, torba yoğurt üretimi sırasında esansiyel olmayan elementlerin konsantrasyonları belirlenmiş ve bu elementlerin günlük alımları hesaplanmıştır. Elementlerin [alüminyum Al , antimum Sb , arsenik As , bor B , berilyum Be , kadmiyum Cd , nikel Ni , kurşun Pb , gümüş Ag , titanyum Ti , talyum Tl ve vanadyum V ] belirlenmesi, Varian Vista-MPX indüktif eşleşmiş plazma optik atomik emisyon spektrometresi ICP-OES ile gerçekleştirilmiştir. Süt, yoğurt, torba yoğurt ve serumda en fazla belirlenen element Bor B olmuştur. Be ve V hariç diğer elementlerin miktarı torba yoğurt üretimi sırasında önemli düzeyde değişmiştir P
