Abstract:Namen raziskave je bil določiti vsebnost suhe snovi, pepela in pomembnejših mineralov (Ca, Mg in P) v mleku sesalcev domačih živali, kokosovem mleku in mlečnih napitkih rastlinskega izvora ter na osnovi rezultatov podati prispevek uživanja mleka k dnevnemu vnosu posameznih mineralov v organizem. Koncentracije Ca in Mg smo določili z atomsko absorpcijsko spektrometrijo, koncentracije P pa z molekulsko absorpcijsko spektrometrijo. Analizirali smo 4 vzorce iz vsake skupine živil (skupaj 24 vzorcev). Najvišjo vsebnost suhe snovi smo izmerili v kravjem surovem mleku (12,3 %) in najnižjo v sojinem napitku (5,8 %), medtem ko je bila vsebnost pepela najvišja v kozjem in homogeniziranem kravjem mleku ter kokosovem mleku. Največ Ca vsebujeta kozje in homogenizirano kravje mleko (135 mg/100 g) ter sojin napitek (44 mg/100 g). Vsebnosti Mg so bile od 1,93 mg/100 g v riževem napitku do 15,21 mg/100 g v kokosovem mleku in P od 6,14 mg/100 g v riževem napitku do 95 mg/100 g v surovem kravjem in kozjem mleku. Mg v mleku statistično značilno pozitivno korelira s Ca, v mlečnih napitkih pa s P. Odrasla moška oseba pri zaužitju 1 dcl mleka pokrije približno desetino dnevnih potreb po Ca in P.

Title:Macronutrient Determination in Domestic Mammal Milk and in Plant Based Milk Alternatives
Abstract:The purpose of this research was to determine the content of total solids, ash and important minerals (Ca, Mg and P) in domestic mammal milk, coconut milk plant based milk alternatives and, on the basis of the results, show the contribution of milk consumption to the daily intake of individual minerals in the organism. The concentrations of Ca and Mg were determined using atomic absorption spectrometry and P concentrations via molecular absorption spectrometry. We analyzed 4 samples from each group of foodstuff (total of 24 samples). The highest content of solids was measured in cow raw milk (12.29 %) and the lowest in soy beverage (5.76 %), while the ash content was the highest in goat and homogenized cow milk and coconut milk. Goat and homogenized cow’s milk contain the biggest amount of Ca (135 mg/100 g) and soy beverage contains (44 mg/100 g). The Mg content was ranged from 1.93 mg/100 g in rice beverage to 15.21 mg/100 g in coconut milk and P from 6.14 mg/100 g in rice beverage to 95 mg/100 g in raw cow and goat milk. Mg in cow milk statistically significantly positively correlates with Ca, and in milk beverages with P. An adult person covers about one tenth of the daily requirements for Ca and P when consuming 1 dcl of milk.
