The invention relates to a preparation method of a spirulina soft sweet, belonging to the technical field of
food processing. The spirulina soft sweet comprises the following components based on parts by weight: 100 parts of saccharides, 0.06-10.0 parts of spirulina
powder, 1.8-20.0 parts of gel, 0.1-1.2 parts of
citric acid, 0.0001-0.5 parts of
menthol crystal and 0.0001-5 parts of
ginger oil. The preparation method comprises the steps of: preparing the spirulina
powder into thin paste with water; dissolving the gel; evenly mixing the saccharides except the
glucose syrup and dissolving by adding water; injecting the gel solution into dissolved saccharides solution, sugaring off in a heating way (injecting the
glucose syrup after the saccharides solution is boiled for 5-10 minutes if the prescription has the
glucose syrup), and stopping heating until that the concentration of the saccharides solution reaches 75-87; adding the
citric acid, the spirulina solution, the
menthol crystal and the
ginger oil when the temperature of the saccharides solution is cooled to be 75-79.9 DEG C or 90.1-110 DEG C, evenly mixing, pouring into a model, and statistically putting, so that the soft sweet is solidified; and pouring from the model after the soft sweet is solidified, and transporting into a
drying room to be dried until that the soft sweet is not sticky. The spirulina soft sweet prepared by the method has pleasant color and luster, suitable sour and sweet, and a bit glutinous texture, and doest not stick teeth. The added spirulina has abundant
protein,
vitamin and various mineral elements during
processing, thereby making up for the deficiency that the existing soft sweet is testable but undernourished, and being a healthy sweetmeat for all persons.
