WebThe citric acid acted both as a crosslinking agent and a plasticizer in the starch films (Ghanbarzadeh et al. 2011). It has also been reported by Yu et al. (2005) that citric acid can form strong hydrogen bond interactions with starch and improve its thermal and water stability. Starch is the major carbohydrate reserve in plants.
