Abstract

The invention discloses a preparation method for compound modified starch. The method comprises the following steps: (1) taking native starch and water and preparing into slurry; (2) adding sodium hydroxide into the slurry of the native starch, adjusting the pH value to 8-9, then adding acetic anhydride, and vibrating for reacting for 1-2 hours under a certain temperature condition; (3) adding a cross-linking agent, citric acid and cellulose into the starch slurry, reacting for 1-2 hours at the temperature of 40-50 DEG C, then adding hydrochloric acid and adjusting the pH value to 6.5-7; and (4) washing, centrifuging and drying the starch till the water content is below 15%, then increasing the temperature to 100-120 DEG C, keeping for 0.5-1 hour and cooling, thereby acquiring the modified starch. The compound modified starch prepared according to the method disclosed by the invention has the advantages that after fresh meat is soaked into the solution of modified corn starch and then is taken out, the water drop loss of the meat in the storage process can be reduced, the water content and pH value of the meat can be increased, and the influence on the color of the meat is less.

Description

The preparation method of composite modified starch
Technical field
The present invention relates to modified starch field, more particularly to a kind of preparation method of composite modified starch.
Background technology
To improve the performance of starch, expanding its range of application, using physics, chemistry or enzymatic treatment, on starch molecule Introduce new functional group or change starch molecule size and starch granular property, so as to change starch natural characteristic (such as:Gelatinizing Temperature, thermoviscosity and its stability, freeze-thaw stability, gel force, film property, the transparency etc.) so as to more suitable for certain application Requirement.It is this through secondary operations, the starch for changing property is referred to as modified starch.
After chilled meat refers to that poultry meat is slaughtered, pre-cooled acid discharge is anxious to freeze, and stores below -18 DEG C then, deep layer meat Wen Da -6 Meat below DEG C.Typically in -28 DEG C to -40 DEG C anxious jellies, meat, fragrance are differed not high-quality chilled meat with green meat or Chilled Meats Greatly;If freezing at a lower temperature, meat, fragrance have larger difference, and this is also that most people thinks that chilled meat is unpalatable Reason.But the chilled meat of two ways, its storage life is all longer, therefore is widely adopted.
The information for being disclosed in the background section is merely intended to increase the understanding of the general background to the present invention, and should not When the prior art for being considered to recognize or imply in any form the information structure well known to persons skilled in the art.
