The invention discloses red raspberry
effervescent granules and a preparation process thereof, and belongs to the technical field of preparation of
effervescent granules. The red raspberry
effervescent granules disclosed by the invention comprise the following components in percentage by weight based on the total weight of the effervescent granules: 15-25% of red raspberry extract freeze-dried
powder, 40-60% of
mannitol, 2-6% of an
adhesive, 30-40% of a disintegrating agent, 0.5-2% of a flavoring agent and 0.1-1% of an inclusion agent, the preparation method comprises the following steps: uniformly mixing freeze-dried
powder of the red raspberry extract,
citric acid serving as an acidic disintegrating agent and
mannitol serving as a
diluent, adding a solution containing an
adhesive to prepare wet acid particles, and
drying to obtain acid particles; uniformly mixing the included alkaline disintegrating agent
sodium bicarbonate with the
diluent mannitol, adding the solution containing the
adhesive to prepare wet alkali particles, and
drying to obtain alkali particles; and uniformly mixing the obtained acid particles, alkali particles and a flavoring agent to obtain the red raspberry extract effervescent particles. The preparation process disclosed by the invention is scientific, reasonable, simple and feasible, low in cost and high in benefit, and provides a certain reference for subsequent development of functional foods.
