文摘

Brittleness of high amylose corn starch film reduced by hydroxypropylation. Optimal hydroxypropylation of starch occurred with propylene oxide (PO) at 6% starch weight basis. Films with more PO and plasticizer produced more flexible but weaker films. Integrity and mechanical properties of film improved by adding glycerol of 15–20% (w/w).
