Embodiment 1
[0056] (1) Preparation of concentrated juice from cooking liquid of hairy shrimp
[0057] (1) Pre-concentration: vacuum-concentrate the cooking liquid of hairy shrimp at 70°C and a vacuum degree of -0.08MPa to a solid content of 15% to obtain a concentrated solution.
[0058] (2) Enzymolysis: After adjusting the pH of the concentrated solution to 7, add a compound enzyme with a mass of 0.5% of the concentrated solution, and carry out constant temperature enzymolysis at 55°C for 6 hours to obtain an enzymatic hydrolysis solution. The compound enzyme is made by mixing neutral protease and flavor protease with a mass ratio of 1:3.
[0059] (3) Enzyme inactivation: Heat the enzymolysis solution to 100°C and maintain it for 10 minutes to obtain an enzyme inactivation solution.
[0060] (4) Deodorization: Add 0.2% yeast powder in the enzymolysis liquid to the enzyme inactivating liquid, and stir continuously at 35°C for 1.5 hours to obtain the deodorizing liquid.
[0061] (5) Deod...
Embodiment 2
[0069] (1) Preparation of concentrated juice from cooking liquid of hairy shrimp
[0070] (1) Pre-concentration: vacuum-concentrate the shrimp cooking liquid at 75°C and a vacuum degree of -0.075 MPa to a solid content of 12% to obtain a concentrated liquid.
[0071] (2) Enzymolysis: adjust the pH of the concentrated solution to 6, add a compound enzyme with a mass of 0.4% of the concentrated solution, and carry out constant temperature enzymolysis at 60°C for 7 hours to obtain an enzymatic hydrolysis solution. The compound enzyme is made by mixing neutral protease and flavor protease with a mass ratio of 1:3.5.
[0072] (3) Enzyme inactivation: Heat the enzymatic hydrolysis solution to 90°C and maintain it for 15 minutes to obtain an enzyme inactivation solution.
[0073] (4) Deodorization: Add 0.1% yeast powder in the enzymolysis solution to the enzyme inactivation solution, and stir continuously at 40°C for 2 hours to obtain the deodorization solution.
[0074] (5) Deodor...
Embodiment 3
[0081] (1) Preparation of concentrated juice from cooking liquid of hairy shrimp
[0082] (1) Pre-concentration: vacuum-concentrate the cooking liquid of hairy shrimp at 75°C and vacuum degree of -0.07MPa to a solid content of 10% to obtain a concentrated solution.
[0083] (2) Enzymolysis: adjust the pH of the concentrated solution to 8, add a compound enzyme with a mass of 0.6% of the concentrated solution, and enzymolyze at a constant temperature of 40°C for 10 hours to obtain an enzymatic solution. The compound enzyme is made by mixing neutral protease and flavor protease with a mass ratio of 1:4.
[0084] (3) Enzyme inactivation: Heat the enzymolysis solution to 95°C and maintain it for 12 minutes to obtain an enzyme inactivation solution.
[0085] (4) Deodorization: Add 0.3% yeast powder in the enzymolysis solution to the enzyme inactivation solution, and stir continuously at 30°C for 1 hour to obtain the deodorization solution.
[0086] (5) Odor removal: add β-cyclode...
