| Changes in phytic acid content, activity of phytase and α-amylase in rye breads were determined during rye bread making. The activity of phytase is highest in grain and flour whereas the activity in the sourdoughs is almost the half of the activity in the flour. The activity was unchanged in the dough after mixing and proofing. Degradation of phytic acid (IP6) into lower inositol-phosphates and free phosphate is almost completed during the production of rye bread with long fermentation time whereas the degradation is less completed when whole grains are included in the recipe. In rye bread made from milled rye (DB00), 99% of IP6 is degraded and IP3 becomes the dominating inositol-phosphate in this bread type presumably resulting in a high level of... |

| Der er en stigende interesse hos forbrugeren og i fødevareindustrien for at sikre, at vores fødevarer er sunde, af høj kvalitet og ikke mindst sikre. Dette kræver hurtige, pålidelige analysemetoder, gerne med mulighed for at automatisere analysen direkte at- eller online. Spektroskopi er særdeles velegnet til sådanne formål, og forskellige former for spektroskopi bruges allerede i fødevareindustrien, f.eks. fluorescens, infrarød og nærinfrarød samt lavfelts kernemagnetisk resonans (LF NMR) spektroskopi. Hidtil har der dog ikke været tradition for at anvende højopløst (high resolution, HR)NMR-spektroskopi inden for fødevarevidenskaben.Dette på trods af en udbredt anvendelse fra opklaring af kemiske strukturer for små molekyler i opløsning, strukturopklaring... |
