The invention relates to a method for preparing a scallion chicken-flavor compound seasoning by combining vacuum frying with a microcapsule embedding technology, aiming at effectively solving the problems of a conventional compound seasoning that nutrient loss is serious, pollution is serious, energy consumption is great and efficiency is low. The method comprises the following steps: heating palm oil and chicken fat to 110 DEG C; adding a sweet sauce, 3 / 5 of chicken, scallions, garlic, ginger, chilies, peppers, anises and cassia bark to vacuum frying equipment and sealing, boiling oil at 95-105 DEG C, carrying out vacuum-frying for 35-45min, and adding salt, white sugar and monosodium glutamate to obtain a vacuum-fried product; adding water to 2 / 5 of chicken, heating to 55 DEG C, adding compound protease and implementing enzymolysis, heating, and carrying out enzyme deactivation and sterilization to obtain an enzymatic hydrolysate; adding glucose and hydrolyzed vegetable protein powder to the vacuum-fried product and the enzymatic hydrolysate, heating and increasing temperature, implementing an Maillard reaction, adding modified starch and carrying out microcapsule embedding, homogenizing and drying to obtain the compound seasoning. The compound seasoning is scientific in composition, easy to operate, good in color, aroma and taste, rich in nutrition, energy-saving and environment-friendly, and high in production efficiency.
