The invention discloses a formula and production process of crystal sugar bird's nest, and relates to the technical field of bird's nest. The production process of the crystal sugar bird's nest comprises the following steps of: a, washing a pot, disinfecting and filtering prepared purified water, pouring the purified water into the pot, setting the temperature of the pot to be 150 DEG C, and quickly preheating the purified water in a pot body; and b, when the temperature of the purified water reaches 40-50 DEG C, mixing prepared crystal sugar, white granulated sugar, bird's nest, collagen peptide, acerola cherries, roses and resistant dextrin, putting a mixture into the pot, and stirring the raw materials in the pot in a boiling process. Before the bird's nest is boiled, the water is preheated, and the pot body can be disinfected, so that the boiled bird's nest is healthier; meanwhile, the bird's nest and other ingredients can be rapidly heated when being put into the pot, so that theboiling process of the bird's nest is accelerated, and the nutrition loss rate of the bird's nest is reduced; and in addition, in the boiling process of the bird's nest, ingredients such as fruit juice are added, so that the taste and fragrance of the bird's nest are improved.
