Agent.
Technical background
Steamed bun is one of traditional staple food of Chinese people, northern particularly in China, steamed bun be in people's daily life most
One of main staple food.With the increasingly raising that people opposite product property requires, also more and more to the needs of high-quality steamed bun
Strongly, this whiteness for being mainly reflected in steamed bun.In terms of the whiteness raising of steamed bun, it was often used chemical whitening agent benzoyl peroxide in the past
After the steamed bun of formyl (Benzoyl Peroxide, BPO) to make steamed bun brighten, but be added to this chemical whitening agent is eaten by people
Human body can be damaged, therefore be forbidden to use this chemical whitening agent now.
The one kind that CN103371426B discloses brightens steamed bun antistaling agent, by lipase, amylase, zytase, malt
Saccharogenic amylase, starch, glyceryl monolaurate, citric acid, sucrose ester and vitamin C composition, it is real according to the description of its specification
Existing whitening effect is mainly the collaboration using the lipase and amylase, zytase of the Lipopan S from Novozymes Company
Effect.
But in steamed bun preparation process, there is still a need to remove selection more suitably lipase to prepare better enzyme combination
Object, to improve the quality of steamed bun, such as while keeping steamed bun whiteness, additionally it is possible to improve the exquisiteness of steamed bun institutional framework
Degree.
Summary of the invention
The present invention relates to a kind of enzymatic compositions comprising lipase, amylase and zytase, wherein the lipase selects
