摘要
Disclosed is a novel amylase which mainly forms maltohexaose and maltoheptaose when acts on starch, but does not substantially hydrolyze maltohexaose and a lower molecular oligosaccharide than maltohexaose. The amylase can be prepared from microorganisms of the genus Alcaligenes, and has a relatively-high optimum temperature and thermal stability, as well as a relatively-wide range of optimum pH and pH stability. By using the amylase, saccharide compositions rich in maltohexaose and/or maltoheptaose or those rich in maltohexaitol and/or maltoheptaitol can be readily prepared in an industrial scale, and the saccharide compositions thus obtained can be used in a variety of food products, cosmetics and pharmaceuticals.
