The invention belongs to the field of processing of aquatic products, and relates to a processing method of crangon affinis meat. The processing method comprises the following steps of performing vacuum deep-frying on pretreated crangon affinis meat, wherein the vacuum deep-frying temperature is 80-120 DEG C, the deep-frying time is 6-10min, the negative pressure of vacuum degree is 0.098-0.08MPa,and the pretreatment of the crangon affinis meat comprises the following steps of sequentially performing low-temperature rinsing on crangon affinis, removing heads, shells and intestinal glands, cutting apart backs, keeping tails, performing low-temperature rinsing, performing soaking in salt water, performing pre-cooking, performing powder pre-wrapping, performing pulp wrapping, performing bread crumb wrapping and performing cold storage. In the pulp pre-wrapping process of the crangon affinis meat, ingredients are in reasonable compatibility, so that pre-wrapped pulp is rich in high cellulose, multivitamins and trace elements, the pre-wrapped pulp is better matched with the crangon affinis meat to obtain more nutrition, and the nutritive structure of deep-fried foods can be improved; and then through pre-cooking, powder pre-wrapping, pulp wrapping, cold storage and deep-frying, the running off of nutrient substances can be greatly reduced, detrimental effects of microorganisms andenzymes can also be restrained, and the original fragrance, the original nutrition and the original meat quality are sufficiently maintained.
