Compound steamed-bread preserving modifier

Abstract

The present invention belongs to the field of food preserving technology, and is especially one kind of compound steamed bread preserving modifier comprising starch hydrolase 1-7 wt%, hemicellulase 3-7 wt%, lipase 3-7 wt%, emulsifier 40-70 wt%, hydrophilic colloid 15-40 wt%, and coagulation inhibitor 2-6 wt%. The compound steamed bread preserving modifier can improve the internal structure of steamed bread, soften core, promote the form of cellular gluten structure, raise the antiageing performance, raise total water content and delay water-losing ageing of steamed bread.

Description

technical field [0001] The invention belongs to the technical field of food preservation and relates to a freshness-preserving and anti-aging compound improver for steamed bread. Background technique [0002] The newly made steamed buns have the characteristics of soft, elastic and good taste in the internal tissue structure, but as the storage time prolongs, they will change from soft to hard, the tissue will become loose and rough, and the elasticity and flavor will also disappear. Aging of buns. Due to the small sales radius of steamed buns at present, they are sold on the same day of production, and are generally not kept fresh. It will cause secondary pollution to the steamed bread. At the same time, the high water content of the skin of the steamed bread creates a good living environment for bacteria. With the extension of storage time, the number of bacterial colonies begins to increase, and pathogenic bacteria may appear, which greatly shortens the shelf life of ste...

AI Technical Summary

Problems solved by technology

Due to the small sales radius of steamed buns at present, they are sold on the same day of production, and are generally not kept fresh. It will cause secondary pollution to the steamed bread. At the same time, the high water content of the skin of the steamed bread creates a good living environment for bacteria. With the extension of storage time, the number of bacterial colonies begins to increase, and pathogenic bacteria may appear, which greatly shortens the shelf life of steamed bread. Safety, the shelf life of steamed buns is generally 1-3 days

At present, the preservation of pasta is mainly quick-freezing and adding chemical preservatives. The cost of quick-freezing fresh-keeping is high, and it is generally suitable for high-end pasta preservation. The addition of chemical preservatives is mainly sodium benzoate, etc., which are harmful to the human body and are not recommended. Currently, there is no such treatment for steamed bread. Appropriate and convenient preservation method
