The invention relates to seacucumber-blueberry instant particles and a processing method thereof. Seacucumber, blueberry and barbary wolfberry fruit are taken as major raw materials, vitamin C, citric acid, xylitol, a sweetener and an excipient are taken as auxiliary raw materials and nutrient components such as zinc gluconate, taurine, vitamin E acetate, collagen, L-carnitine, calcium gluconate and the like are added as required by different people. The method comprises the following steps of: performing pretreatment, biological enzymolysis, extraction and drying on the raw materials; extracting active components in the raw materials; and mixing, pelletizing, drying and disinfecting the active components to obtain the instant particles. Protein in the seacucumber is hydrolyzed to exist in the form of small molecule peptides so that the protein is easy to be absorbed by human bodies, the activities of nutrient substances in a mixture are kept, the active components are stabilized in a product, the original juice, original taste and original colors of the raw materials are kept and the medicinal value, nutrient value and drinking value of the mixture of a plurality of raw materials are enhanced. The particles have the advantages of bright color, uniform form, stable property, rich nutrition, pleasant sweetness and sourness, convenient drinking and remarkable nourishing effect.
