Amylose obtained by hydrolysis of starch with alpha-1,6-glucosidase is used together with a suitable plasticiser to prepare amylose films of which the amylose has differing degrees of polymerisation and contains hardly any amylopectin. The hydrolysed starch is pref. fractionated to give the desired content of long-chain amylose with a degree of polymerisation of more than 100. The prefd. plasticiser used is a polyalcohol and the prefd. enzyme is obtained from species Pseudomonas. The films produced from this material may be used as packing materials for food in powder-form and for deep-freeze meat products. The films have improved resistance against oil, are little permeable for oxygen and have good mechanical props. They are transparent and show nearly 100% light-transmittance.
