Table 1 Degrees of substitution for enzymatic acylation of different starches with decanoic acid using lipase from Thermomyces lanuginosus (lipolase)

From: Lipase-catalysed acylation of starch and determination of the degree of substitution by methanolysis and GC

Starch source DSa % Amylose
Amylose 0.0025 ± 0.0006 100%
Hylon VII (high amylose) 0.0039 ± 0.0005 70%
Wheat 0.0042 ± 0.0001 25%
Maize 0.0040 ± 0.0006 25%
Tapioca 0.0093 ± 0.0011 17%
Amioca (high amylopectin) 0.0084 ± 0.0010 < 1%
  1. aAnalysis with transesterification/GC method, errors are standard deviation for triplicate experiments, all controls had DS < 0.00001. The values for amylose content were given by the suppliers of each starch type.
