The invention discloses an apple
protein puffed toast and a preparation method thereof, the product takes fresh apples and high-purity
whole egg protein powder as unique raw materials, and the
mass ratio of the raw materials is (90-97): (3-10); the preparation method comprises the following steps: pretreating apples with clear water, performing segmented temperature-controlled baking, performing directional
grinding to prepare paste, performing
vacuum cooling, performing pulping and foaming, performing shaping and baking, performing gradient
moisture regaining, and performing sealed packaging. According to the preparation method, 1-2 g / 100 g of natural fibers in fresh apples are concentrated to be larger than or equal to 10 g / 100 g in a finished product through the technologies of baking, concentration and
fiber content increasing, high-
sugar-degree stacking, low-
moisture synergistic
fiber softening and pulping, foaming, air wrapping and puffing, and the size is expanded to be 2.8-3.2 times of the initial size through pulping and foaming; the final product is in a regular rectangular toast shape, is internally of a
fiber interlaced porous puffed structure, has the characteristics of
high sugar degree, low
moisture, high fiber,
high protein and zero fat, has fiber chewing feeling and elastic taste, fills the market blank, and is suitable for large-scale production.
