The invention discloses a banana and pea starch food and a production method thereof, and belongs to the field of food processing. The food is produced by using the following components, by weight, 40-50 parts of pea starch, 2-4 parts of black tea submicron powder, 7-10 parts of oligosaccharide, 40-50 parts of freeze-dried granular banana, 3-5 parts of xylitol and 2.8-4 parts of an agar liquid. The method comprises the following steps: taking the pea starch and the black tea submicron powder, gelatinizing the pea starch and the black tea submicron powder in a boiling water bath, rapidly pouring the obtained gelatinized powder emulsion into a heatproof packaging container, taking the freeze-dried granular banana, adding the banana into the fused agar liquid, and pouring the obtained mixture to the surface of the gelatinized powder emulsion; and carrying out low temperature retrogradation treatment, and packaging. The pea starch with high content of amylose and strong retrogradation ability is adopted as a raw material, and is not heated in the processing production process, and granular heat-intolerant natural resistant starch RS2 in the pulp of banana is reserved. The food has the advantages of flawless color, suitable sweetness, good hardness, high chewiness and good mouthfeel, and the production method has the advantages of simplicity, convenient operation, and suitableness for industrialized popularization.
