papain hydrolysis,
fermentation-based deodorization via
activated carbon and
yeast, secondary debitterizing via beta-
cyclodextrin embedding with mycose, decoloring via diatomite, color optimizing via bamboo leaf
flavonoid and neutral
sodium phytate, and taste optimizing via compound flavoring (comprising glucose, fructo-
oligosaccharide and
xylitol). The preparing method has the advantages that the process is advanced, the formula is scientific and reasonable, the nutrients are complete, the fishy smell is slight, the composition has natural
