Embodiment 1
[0025] In this embodiment, protein and chitin are extracted from shrimp heads and shrimp shells by fermentation of Pediococcus lactis. The specific steps are as follows:
[0026](1) Take 50g of fresh shrimp heads and shrimp shells, crush the shrimp heads and shrimp shells to about 0.5cm, add 25mL of water (50% of the total mass of the shrimp heads and shrimp shells), and adjust the pH to 6.4;
[0027] (2) add 7.5g glucose again (15% of shrimp head and shrimp shell gross mass);
[0028] (3) Pediococcus lactis is inoculated, and the inoculation amount is 5% of the total mass of the shrimp head and the shrimp shell;
[0029] (4) Insulated and fermented at 35°C for 5 days;
[0030] (5) After the fermentation is finished, centrifuge the fermented liquid and the fermentation residue; the fermented liquid is neutralized by sodium carbonate, concentrated, and spray-dried to obtain 7.2 g of powdered substance, which is the protein obtained in this embodiment;
[0031] (6) The ferment...
Embodiment 2
[0033] In this embodiment, protein and chitin are extracted from shrimp heads and shrimp shells by fermentation of Pediococcus lactis. The specific steps are as follows:
[0034] (1) Take 100g of fresh shrimp heads and shrimp shells, crush the shrimp heads and shrimp shells to about 0.5cm, and adjust the pH to 6.5;
[0035] (2) add 20g glucose again (20% of shrimp head and shrimp shell gross mass);
[0036] (3) Pediococcus lactis is inoculated, and the inoculation amount is 3% of the total mass of the shrimp head and the shrimp shell;
[0037] (4) Insulated and fermented at 30°C for 7 days;
[0038] (5) After the fermentation is finished, centrifuge the fermented liquid and the fermentation residue; the fermented liquid is neutralized by sodium carbonate, concentrated, and spray-dried to obtain 14.7 g of powdery substance, which is the protein obtained in this embodiment;
[0039] (6) The fermentation residue was soaked in 0.4 mol / L dilute hydrochloric acid for 6 hours, then...
