    • Fat determination in dairy products by Soxhlet
      <p>A simple and reliable procedure for fat determination of food and feed products according to Weibull-Stoldt is introduced. The sample is hydrolyzed with the HydrolEx H-506. The Soxhlet extraction is performed with the FatExtractor E-500. Calculation of total fat content follows gravimetrically after the extract has been dried to a constant weight.&nbsp;</p>, html_buchi

    • Separation of Egg White Proteins by Flash & prep HPLC
      <p>This study investigates the separation of egg white proteins using flash and prep HPLC with silica stationary phases varying in pore and particle sizes. Larger pore <br>sizes improved protein interaction with the stationary phase, while particles above 10 µm were ineffective. Optimal separation was achieved using the Pure Excellence C-950 with a PrepPure C18WP column, combining wide pores, small particles, and a step gradient.</p>, html_buchi
