The invention discloses a method for improving quality of low-salt-content
fermented fish by utilizing a staged temperature-controlled
fermentation technology and a product thereof. The method for improving the quality of the low-salt-content
fermented fish by utilizing the staged temperature-controlled
fermentation technology comprises the following steps of: carrying out
pickling, namely addingedible salt and white granulated
sugar into fish pieces, and carrying out stirring so as to perform
pickling; carrying out
drying, namely
drying the pickled fish pieces; preparing auxiliary materials,namely blending auxiliary materials; carrying out blending, namely mixing the
dried fish pieces with the blended auxiliary materials, and carrying out blending; carrying out sealing, namely sealing the fish pieces blended with the auxiliary materials; and carrying out staged temperature-controlled
fermentation, namely respectively carrying out fermentation at 22-25 DEC G and at 30-32 DEG C. On basis of traditional
fermented fish preparation technologies, the method for improving the quality of the low-salt-content fermented fish utilizes a two-stage temperature-controlled fermentation technology so as to further inhibit spoilage bacterium growth and
biogenic amine production, and thus, product safety is improved; moreover, ester producing and
aroma increasing capacities of microorganismsare improved by raising late-stage fermentation temperature so as to improve product
flavor and sensory quality, as well as shorten fermentation period. The method for improving the quality of the low-salt-content fermented fish by utilizing the staged temperature-controlled fermentation technology can also be applied to other fermented foods; moreover, the method is conducive to industrial production and scale production, and has wide market prospects.
