Instructions for purchasing fish meal processing equipment for enzymatic hydrolysis of fish soluble protein powder Overview of the application of fish pulp (partly taken from the Internet)[1][2] Fish lysate is the squeezed waste water produced during the production of fish meal. For every ton of fish meal produced, two to three times as much fish lysate is produced. In the previous fishmeal production process, the fish pulp was usually discharged directly into the environment, which not only wasted this protein-rich resource, but also caused serious environmental pollution. In recent years, industry researchers have done a lot of research on how to use fish pulp, such as the use of fish pulp to produce food-grade umami (CN107136465A). The obtained umami agent is easy to absorb and has sufficient savory flavor, or the use of fish soluble pulp The preparation of protein fertilizer can not only provide nutrients to crops and increase yield, but also improve soil conditions and promote healthy growth of crops. Because the fish pulp is derived from marine fish, it has a unique fishy smell. After the hydrolysis process, other flavor substances are produced. It is a high-quality feed additive. Hydrolysis method [1] A production method of hydrolyzed fish pulp, specifically including the following steps: Inject 200 parts of fish lysate into the heating and cooking device, and cook at 85°C for 40 minutes to sterilize and kill enzymes. After cooling, add Lactobacillus plantarum, Lactococcus lactis, and Lactobacillus brevis complex bacteria. The inoculation amount is 5%. Fermented at ℃ for 3 days, after the fermentation, 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 enzymatic hydrolysis, enzymatic hydrolysis for 2 hours After that, vacuum distillation is performed again to remove excess water, and the concentration is at the same time to inactivate the enzyme. When the water content is reduced to 45%, stop heating, and then apply 60V/cm AC electric field for 6min, and then canned after cooling. The finished product of hydrolyzed fish pulp. Application [2-3] A process for producing fish peptone by using fish lysate, including the following steps: (1) Blending: Take appropriate amount of water and add it to the stock solution of fish soluble slurry to form a fish soluble slurry with 80% water content. (2) Sterilization: increase the temperature to 90 degrees and use infrared rays for sterilization.
