Presentation Transcript

  1. Stivelse og amylaser • Kulhydrater • amylose og amylopektin • Glukosemolekyler

  2. Amylose Amylopektin

  3. Stivelse • Stivelseskorn • Opdelt i lag • Rund struktur • Uopløselige i vand

  4. Gelatinisering/ forklistring • Vand + temp. stigning • Optager vandet • Svulmer op • Tykt flydende • Modtagende overfor amylaser • Går i stykker

  5. Retrogradering • Reorganisering • Danner nye bindinger • Med til at gøre brød hårdt

  6. Amylaser • Enzymer • α- og β-amylase • Nedbryder stivelsen • 2 forskellige måder • Primært β-amylase
