The invention discloses a preparation method and application of a bread baking brightener, and belongs to the technical field of food. The
plant-based baking brightener is prepared by taking
pea protein as a main
raw material, compounding a small amount of
gellan gum and an
oil phase to construct a stable emulsification
system, and performing simple processes of dissolving, mixing, dispersing, homogenizing and the like. The brightener is free of animal-derived components,
reducing sugar is not added, a continuous, compact and uniform film layer can be formed on the surface of bread during baking, uniform and stable
Maillard reaction coloring is achieved, the
surface brightness, color uniformity and appearance integrity are improved, the original
flavor of a product is not affected, and the good
specific volume and texture of the bread can be maintained. The product adapts to vegetarian people and egg
allergy people, conforms to the trend of
label cleaning, low-
sugar diet and
plant-based food, is high in storage stability, simple in preparation process, free of complex equipment and easy for large-scale production, can effectively replace egg liquid, and expands
consumer groups and market application range of baked food.
