Production method for crushing hydrolyzed fish dissolving slurry by grinding pump
Release time：2020-06-05 Publisher：admin
Production method of crushing and hydrolyzing fish dissolving slurry by grinding pump, application of fish dissolving slurry
Fish syrup is the squeezed wastewater generated during the production of fish meal. Every ton of fish meal produced will produce two to three times the amount of fish syrup. In the previous fishmeal production process, fish paste was usually discharged directly into the environment, which not only wasted this protein-rich resource, but also caused serious environmental pollution. In recent years, researchers in the industry have done more research on how to use grinding pumps to crush fish paste. For example, using fish paste to produce food grade umami (CN107136465A), the obtained umami is easy to absorb, and the umami is sufficient, or The preparation of protein fertilizer (CN105060944A) by fish dissolving pulp not only provides nutrients for crops and increases production, but also improves soil conditions and promotes healthy growth of crops. Because fish pulp is derived from marine fish, it has a fishy peculiar smell. After the hydrolysis process, other flavor substances are produced, which is a high-quality feed additive.
The specific hydrolysis grinding pump crushing method includes the following steps:
Inject 200 parts of fish paste into the heating cooking device, cook at 85°C for 40 min at high temperature for sterilization and killing enzymes, and after cooling, add Lactobacillus plantarum, Lactococcus lactis and Lactobacillus brevis complex, inoculation amount 5%, in 30 Fermentation at ℃ for 3 days, after the fermentation is completed, adjust the pH to 10.0 with an appropriate amount of 3mol/L sodium hydroxide solution, stir evenly, add 1.5wt% alkaline protease, and continue to stir at 75℃ for enzymolysis for 2 hours Afterwards, the vacuum distillation is performed again to remove excess water, and the enzyme killing effect is achieved while concentrating. When the water content is reduced to 45%, the heating is stopped, and then an AC electric field with a strength of 60V/cm is applied for 6 minutes. After cooling, it can be filled. Hydrolyzed fish paste products.
