Embodiment 1
[0030] Example 1 (small test, 2.5%, 100°C, 8h)
[0031] Take 25g of jellyfish, remove impurities and clean it, according to the ratio of material to liquid 1:30 (W 江蓠菜 :V 水 ) add water, press 1:100 (W 纤维素酶 : V 料液 ) was added to cellulase, pH was adjusted to 6.5-6.7, and enzymatic hydrolysis was carried out at 50 °C for 2 h. Then press 1:25(W 江蓠菜 : V 处理液 ), add the enzymatic hydrolysis to the mixed acid treatment solution containing 0.06% sulfuric acid, 0.012% disodium EDTA, 0.05% oxalic acid, acidify for 40min, rinse with tap water To neutral, then add water at a ratio of 1:20 to the liquid, stir well, adjust the pH value to 7.8 to 8.0, and cook the gelatin at 100°C until the grass is completely cooked to form agar gel. Add Ca(OH) to the agar gel at a ratio of 1:40 2 , fully stirred, and reacted at 100 ° C for 8 h. Then, pass CO into the glue 2 , the glue appears turbid, resulting in CaCO 3 , when the pH value is 8 to 10, stop the introduction of CO 2 , filtered, an...
Embodiment 2
[0033] Example 2 (small test, 5%, 100°C, 8h)
[0034] Take 25g of jellyfish, remove impurities and clean it, according to the ratio of material to liquid 1:30 (W 江蓠菜 :V 水 ) add water, press 1:100 (W 纤维素酶 : V 料液 ) was added to cellulase, pH was adjusted to 6.5-6.7, and enzymatic hydrolysis was carried out at 50 °C for 2 h.
