The Film-Forming Characterization and Structural Analysis of Pectin from Sunflower Heads

A natural low-methoxyl pectin (termed AHP, $\text{DM}=25.9\%$ ) was extracted from dried heads of sunflower and showed better film-forming performance blended with hydroxypropyl methylcellulose (HPMC). The solutions and films of different HPMC/AHP blends were characterized by viscosity, transparency, mechanical properties, loss on drying, water drop...
