Technical Field

The invention relates to a compound color fixative for color protection in a cheese powder processing process, in particular to a compound color fixative for cheese powder processing and a color protection processing method thereof.

Background

Cheese, also called cheese, has the name of "the king of dairy products", not only is nutritious, the output is large, the variety is many, and the added value of the product is high, is one of the largest products of the world dairy product trade. Cheese powder generally takes cheese as a raw material, is divided into processed cheese powder and ground cheese powder, is widely used in foods such as western-style meals, baked foods, yoghourt and the like, and is endowed with cheese flavor; cheese powder currently relies mainly on imports. The processed cheese powder is prepared by taking cheese as a main raw material and researching through high and new technologies such as crushing, vacuum mixing, high-temperature shearing, melting, emulsifying, pressure spray drying and the like. The defects of color change, brown stain, taste change and the like can occur during high-temperature shearing, melting and emulsification in the processing process. The invention aims to provide a compound color fixative and a color fixation processing method so as to improve or avoid the defects of color change, browning, taste change and the like.

Disclosure of Invention

The invention aims to provide a compound color fixative and the usage amount thereof, and also provides a method for processing cheese powder by color fixation of the compound color fixative, which can reduce the defects of browning, taste change and the like in the processing process of the cheese powder.
