Abstract
A method for preparing a gel product instant-dissolving block includes: adding water into a raw material to dissolve the raw material and carrying out concentrating to obtain a gel solution; carrying out a drying treatment on the gel solution to obtain an irregular cellular gel body; grinding the gel body and carrying out screening to obtain gel powder with a particle size being equal to or larger than 80 meshes; moistening the gel powder with 85 to 95% alcohol and carrying out compression at a compression ratio of 30% to 60% to obtain a block, thereby obtaining the gel product instant-dissolving block. The gel product instant-dissolving block of the present invention has a loose pore structure at the inside, has a high superficial area/volume ratio and has a product density of 0.4 to 0.8 g/cm3, and is capable of being rapidly dissolved within 2 minutes in hot water.
