The invention provides composite baked potato chips and a preparation method thereof.The potato chips comprise potato
chip additives, the potato
chip additives comprise a
powder composition and
emulsion, the
powder composition comprises an emulsifier and vital
gluten, and the
emulsion comprises water, shortening and an emulsifier. The
mass of the
emulsion is 45%-60% of the
mass of the
powder composition. According to the composite baked potato chips, the shortening, the water and the emulsifying agent are prepared into the emulsion, and then the emulsion is slowly mixed with the powder containing the vital
gluten and the emulsifying agent, so that the materials can be mixed more uniformly and better combined together, the texture of the potato chips is more continuous and fine, and meanwhile, the emulsion, the vital
gluten and the emulsifying agent have a synergistic effect; the
hardness and the crispness of the potato chips are improved, the
breakage rate is reduced, the potato chips are easier to process, transport and store, meanwhile, the color and the appearance are improved, and the potato chips are endowed with better taste.
