The invention relates to a cooked black tartary buckwheat food compressed block, which comprises the following components in percentage by weight: 85%-90% of cooked black tartary buckwheat flour, 9%-14% of microcrystalline cellulose, 0.4%-0.7% of citric acid, and 0.3%-0.6% of sodium bicarbonate. The production comprises the following steps: 1. grinding the cooked black tartary buckwheat into flour; 2. placing the cooked black tartary buckwheat powder into a pot at 180-220DEG C, so as to be stir-fried; 3. cooling the cooked black tartary buckwheat to normal temperature; and 4. under the conditions that of the moisture of the cooked black tartary buckwheat, the microcrystalline cellulose and sodium bicarbonate is no more than 3%, placing the following raw materials in percentage by weight: 85%-90% of cooked black tartary buckwheat flour, 9%-14% of microcrystalline cellulose, 0.4%-0.7% of citric acid, and 0.3%-0.6% of sodium bicarbonate into a stirring machine, and performing sufficient mixing and stirring; and 5. compressing the mixture of the stirred cooked black tartary buckwheat flour, microcrystalline cellulose, citric acid, and sodium bicarbonate into blocks each of which is 100g-150g in weight. The cooked black tartary buckwheat food compressed block has the advantages of being convenient to eat and carry, and long in shelf life.
