Description
| - Our work deals with a possibility of determination of basic composition (dry matter, fat, protein, casein, lactose and urea nitrogen) of ewe's milk and colostrum by FT NIR spectroscopy. Samples of milk were warmed to 40 °C, agitated, cooled to 20 °C, transferred to Petri dishes and analysed by reference methods and by FT NIR in reflectance mode. The measured area was spaced by a metallic mirror. Statistically significant differences between the reference values and the calculated values of NIR were not found (p=0.05). Results of calibration for ewe's milk determined the highest correlation coefficients: dry matter 0.983, fat 0.989, true protein 0.997, casein 0.977, lactose 0.980 and urea nitrogen 0.973. The study showed that NIRS method, when samples of milk are measured on Petri dishes, is a useful technique for the prediction of dry matter, fat, protein and casein in ewe's milk.

- Práce se zabývá možností stanovení základních složek ovčího mléka (sušiny, tuku, čistých bílkovin, kaseinu, laktózy a močoviny) FT NIR spektrometrem. Vzorky mléka byly před vlastním měřením zahřáty na teplotu 40 °C, protřepány a ochlazeny na 20 °C. Poté byly umístěny na Petriho misku a proměřeny kovovým zrcátkem na integrační sféře. Výsledky kalibračních korelačních koeficientů: sušina 0.983, tuk 0.989, čisté bílkoviny 0.997, kasein 0.977, laktóza 0.980 a močovina 0.973. Hotové kalibrační modely byly ověřeny křížovou validací. Z - testem nebyly zjištěny rozdíly mezi referenčními hodnotami a hodnotami naměřenými NIR spektrometrem (p=0.05). Na základě uvedených výsledků vyplývá, že NIR spektrometr je možno použít k rychlé analýze základních složek ovčího mléka. (cs)
