The invention discloses a superhigh pressure color protection fresh keeping unfreezing method of frozen livestock meat. The unfreezing method comprises the following steps of cutting the frozen livestock meat sold in the market into blocks, immersing the blocks in a 2%-5% calcium lactate solution for 1-10s, taking out the immersed blocks, and performing vacuum packing; putting the frozen livestockmeat after vacuum packing in a superhigh pressure container, enabling warm water of 30-60 DEG C, of which the mass is 2-10 times of that of the frozen meat, to into the container, performing superhigh pressure treatment under the pressure of 100-300MPa for 15-60min, performing unfreezing, and then placing the unfrozen livestock meat in a place of 0-4 DEG C for refrigeration and sales. The color and the quality of the livestock meat obtained by a color protection fresh keeping technique are both close to those of fresh livestock meat, unfrozen livestock meat is free from a recrystallization phenomenon, the unfreezing time is shortened, besides, the supply chain of domestic and foreign superior livestock meat is extended, and the production benefits are increased.
