Method for preparing algae food based on gel 3D printing

The invention belongs to the field of novel food processing, and particularly relates to a method for preparing algae food based on gel 3D printing. The method comprises the following steps: selecting edible gum, dissolving in a solvent, and stirring to obtain a printing raw material; writing a 3D model printing model according to the principles of increasing the contact area between the algae and the culture medium and stabilizing the model, then setting printing speed, flow and printing temperature parameters, and slicing; then inoculating algae into an algae culture medium for culture, mixing an obtained algae solution with a printing raw material to obtain a mixture, loading the mixture into a material barrel of a food 3D printer, adjusting parameters for printing, curing and cross-linking the obtained product to obtain a cured and cross-linked printing product, and finally putting the cured and cross-linked printing product into the algae culture medium. And culturing to obtain the algae food. Natural al
