Abstract [eng] |
Wheat starch has a high content of non-starch impurities, like proteins and lipid compounds. The majority of the wheat starch lipids are called lysophospholipids, they are highly soluble in water and strong emulsifiers. Starch conversion to sugars is carried out using enzymatic hydrolysis, together with enzymatic degradation of lysophospholipids. Investigation and optimization of enzymatic conversion of phospholipids from glucose syrup was tested with 4 different lipase mixtures. Ultrafiltration process was carried out with a pilot plant system and tubular polymeric membra-nes. The quality of the membrane feed and filtration products was evaluated by determining the molecular masses of saccharides with the size exclusion chromatopgraphy, the amount of phos-phorous, nitrogen, protein, foaming capacity and stability. Semi-quantitative lipid analysis after ultrafiltration was determined with a mass spectrometer. |
