The present invention provides a novel dual-function lipase variant and its application in processing of flour products. The amino acid sequence of the lipase has one of the following 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 in (a) and has at least 80% identity with it. The variants have good performance in processing of flour products, while they can significantly whiten the bread or other products in processing of flour products and significantly increase the specific volume in bread baking process.
