Embodiment 1
[0030] Red algae polysaccharides were prepared by washing Eucheuma, alkali treatment, water washing, pretreatment, enzymolysis, gelatin extraction, plate and frame filtration, potassiation, dehydration by pressure filtration, crushing, and drying.
[0031] (1) Vegetable washing: Soak the Eucheuma in about 18 times of tap water and wash the vegetables for 6 hours.
[0032] (2) Alkali treatment: The washed Eucheuma was treated with a mixture of 7% sodium hydroxide and 6% potassium chloride at 50°C for 18 hours.
[0033] (3) Water washing: Rinse and soak the alkali-treated Eucheuma with tap water until the pH value is neutral, and adjust the pH value to about 6 with 0.18% hydrochloric acid.
[0034] (4) Pretreatment
[0035] Grind the washed Eucheuma with a blade grinder to a size of 5mm, preheat it with hot water to about 50°C, and grind it after 12 minutes.
[0036] (5) Enzymolysis
[0037] Add compound enzyme preparation (protease 45% cellulase 35% pectinase 20%), the addit...
Embodiment 2
[0046] Red algae polysaccharides were prepared by washing carrageen, alkali treatment, water washing, pretreatment, enzymatic hydrolysis, gelatin extraction, plate and frame filtration, potassiation, dehydration by pressure filtration, crushing, and drying.
[0047] (1) Vegetable washing: Soak the carrageen in about 10 times of tap water and wash the vegetables for 8 hours.
[0048] (2) Alkali treatment: The washed carrageen is treated with alkali at 50°C for 24 hours with a mixture of 6% sodium hydroxide and 7% potassium chloride.
[0049] (3) Water washing: rinse and soak the alkali-treated carrageen with tap water until the pH value is neutral, and adjust the pH value to about 6 with 0.18% hydrochloric acid.
[0050] (4) Pretreatment
[0051] Grind the washed carrageen with a blade grinder to a size of 5mm, preheat it with hot water to about 50°C, and grind it after 10-15 minutes.
[0052] (5) Enzymolysis
[0053] Add compound enzyme preparation (50% protease, 30% cellul...
Embodiment 3
[0062] Red algae polysaccharides are prepared by washing vegetables, alkali treatment, water washing, pretreatment, enzymatic hydrolysis, gelatin extraction, plate and frame filtration, potassiation, dehydration by pressure filtration, crushing and drying of Cedar algae.
[0063] (1) Wash vegetables: Soak Shanzao in about 25 times of tap water and wash vegetables for 3 hours.
[0064] (2) Alkali treatment: Alkali treatment of washed vegetables with a mixture of 8% sodium hydroxide and 5% potassium chloride at 50°C for 10 hours.
[0065] (3) Washing: Rinse and soak the alkali-treated Cedar algae with tap water until the pH value is neutral, and adjust the pH value to about 6 with 0.22% hydrochloric acid.
[0066] (4) Pretreatment
[0067] Grind the washed algae to a size of 5 mm with a blade mill, preheat hot water to about 50°C, and grind after 10-15 minutes.
[0068] (5) Enzymolysis
[0069] Add compound enzyme preparation (protease 40% cellulase 30% pectinase 30% mixed), th...
