Dosage du phosphore dans le lait

Abstract: Dans un article précédent (1) nous avons exposé le résultat de notre étude du dosage de calcium dans le lait, étude dont nous avions été rapporteur au sein de la Fédération Internationale de Laiterie.Parallèlement, et avec la collaboration du même groupe de travail, nous avons été amené à étudier le dosage du phosphore total dans le lait.Comme dans le cas du dosage du calcium, le groupe de travail, après une série de travaux préliminaires, a sélectionné un certain nombre de méthodes, puis nous a chargé de les … Show more

“…The calcium and magnesium contents of milk were determined by atomic absorption spectrophotometry in the presence of lanthanum oxide (Sigma Chemical Co, St Louis, Missouri, USA) using a Perkin-Elmer 2380 atomic absorption spectrophotometer (AFNOR, 1993). The phosphorus level was determined by a colorimetric method with ammonium molybdate using an Erma optical AE-11 spectrocolorimeter (Erma optical Works, LTD, Tokyo, Japan) (Pien, 1969). All analyses were performed in triplicate.…”

“…Calcium (Ca), magnesium (Mg), potassium (K) and sodium (Na) were measured by atomic absorption spectrometer model Hitachi Z-6100 (Hitachi Instruments Engineering Co., Ibaraki-ken, Japan) in the presence of lanthanum oxide (Sigma, St. Louis, MO, USA) for Ca and Mg and in the presence of cesium chloride for K and Na. The concentration of phosphorus (P) was determined by a colorimetric method with ammonium molybdate (Pien, 1969).…”

“…The concentration of total phosphorus (P) was determined by a colorimetric method with ammonium molybdate [31]. Micellar organic phosphorus (Po) content was deduced by the difference between the milk's total P at native pH and soluble P at pH 4.8 (i.e.…”
