摘要：

The varietal differences in the rate of esterification of endosperm lutein by fatty acids during the storage of wheat seeds were determined for 138 wheat cultivars. Nine cultivars were found in which esterification did not proceed. The increase in free linoleic acid during storage was no different between the non-esterified and esterified cultivars. This suggests that the esterification of lutein is not caused by lipase, but rather by an unknown acylhydrolase which has a high substrate specificity to lutein.
