The present invention provides a novel dual-function lipase variant and its application in flour products processing. The amino acid sequence of wherein said lipase has one of the following sets of amino acid substitutions: P298T,P298T/H317P, P298T/H317P/V326S, P298T/T218S/S234F, P298T/H317P/P168L/A129S, P298T/S234F/K161R/V326S or the nucleotide sequence of wherein said lipase is substituted, deleted, or added based on the sequence encoding the amino acid described above with at least 80% identity. The variants could significantly whiten and increase the specific volume of the flour product, making themselves great performance in flour products processing. |
