Embodiment 1

[0024] Example 1: Preparation of fucoidan (reference literature: Acta Aquaculture Sinica, 4(1), 9-18, 1980) and addition by infiltration

[0025] In 30g of chopped fresh brown algae, add 300ml of 0.1mol / L HCl to soak for 1 hour, wash with water three times, add 300ml of 1% formaldehyde to soak overnight, wash with water for three times, add 1% NaCO 3 500ml was extracted at 60°C for 1 hour, after filtration, the residue was added with 600ml 0.5% NaCO 3 Extract at the same temperature for 1 hour. Combine the filtrates, after filtering, add 200ml of dilute HCl and water with a volume ratio of 3:10 to produce a large amount of flocculent precipitate, wash twice with water, add 350ml of 2% NaOH solution, stir until completely dissolved, add 50ml of NaClO solution and bleach for 15 minutes , add 700% ethanol, produce filamentous precipitate, get fucoidan, place in P 2 o 5 Dry in a desiccator.

Embodiment 2

[0027] Example 2: One-component fucoidan (reference literature: Acta Biochemistry and Biophysics, 24 (4) 297-302, 1992) and infiltration method

[0028] Use the Sevag method to remove the protein in the polysaccharide, dissolve the fucoidan in 0.1mol / L KCl (pH=7.0), 1mmol / L phosphate buffer, make the polysaccharide concentration 0.1g / L, and then dissolve it in 5×20cm On the CM-Sephadex C25 chromatographic column, wash with 0-4.0mol / L KCl, 1mmol / L phosphate buffer gradient, elute at a flow rate of 0.5ml / min, detect with phenol sulfuric acid method, and collect the main Components were concentrated, dialyzed and freeze-dried to obtain pure polysaccharides. On a Sepharose 6B column of 2.0 cm×60 cm, eluted with 0.01 mol / L phosphate buffer (pH=7.0), a symmetrical single peak was obtained, which was a single molecular weight component.

[0029] Add with reference to Example 1.

Embodiment 3

[0030] Example 3: The synergistic effect of seaweed polysaccharide and vitamin C

[0031] Dissolve 1.0 g of seaweed polysaccharide in 100 ml of distilled water, weigh 1.0 g of vitamin C and mix it with the polysaccharide aqueous solution, place one end of the cigarette filter in the soaking liquid to absorb the solution until the soaking liquid completely soaks the cigarette filter, at 30°C drying.

Abstract

The present invention discloses the application of algal polysaccharide and its derivatives as cigarette filter tip additive. The said algal polysaccharide is polysaccharide of brown algae, red algae and blue-green algae; and the algal polysaccharide derivatives are algal polysaccharide Simth degrading product or aldehyde decomposing product. The algal polysaccharide and its derivatives may be loaded with carrier, active carbon, diatomite or molecular sieve, and the weight ratio between algal polysaccharide and its derivatives and the carrier is preferably 1-3. The cigarette filter tip with the additive has free alkoxyl radical inhibiting rate up to 20-63 % and certain tar eliminating effect.

Description

technical field [0001] The invention relates to the use of seaweed polysaccharide and its derivatives as cigarette filter additives. Background technique [0002] Epidemiological investigations have confirmed that free radicals are the most harmful products in cigarettes. It can directly or indirectly attack and damage cells, and can lead to the occurrence of various diseases. In order to eliminate more toxic substances in cigarettes, in the field of cigarette production, the shredded tobacco itself is generally treated specially, see Chinese patent CN1045515A and US patent 06 / 711,620. Chinese patent CN1228945A adopts sodium alginate to spray on shredded tobacco, dries it, and then makes cigarettes, which can reduce the content of nitrosamines in cigarette smoke. But adopt this method, the dosage of additive is higher, may produce new toxic substance again in the shredded tobacco burning process. Another method is to add a scavenging agent in the cigarette filter, which c...
