摘要：
We disclose a food additive comprising a PS4 variant polypeptide, in which the PS4 variant polypeptide is derivable from a parent polypeptide having non-maltogenic exoamylase activity, in which the PS4 variant polypeptide comprises substitutions at the following positions: 134, 141, 157, 223, 307 and 334 with reference to the position numbering of a Pseudomonas saccharophilia exoamylase sequence shown as SEQ ID NO: 1.
