Embodiment 1

[0026] (1) Extraction: After pulverizing the kelp into 10-mesh kelp powder, take 50g and place it in a container, mix it with deionized water in a weight ratio of 1:20, and extract it in an oil bath at 105°C for 5 hours;

[0027] (2) Concentration: filter and remove the kelp residue to obtain the extract, and concentrate the extract to a concentrated solution with a solid content of 35%;

[0028] (3) Alcohol precipitation: add absolute ethanol to the concentrated solution, after mixing evenly, the final concentration of ethanol is 70% of the volume fraction of the mixture, let stand at 4°C for 12 hours, filter and remove the supernatant, and polysaccharides precipitate;

[0029] (4) Drying: freeze-dry the polysaccharide precipitate to obtain the target product, and the obtained product number is laminarin 1#.

[0030] Laminarin 1# is a brown powder without fishy smell, and the yield is 5.3%.

Embodiment 2

[0032] (1) Extraction: After pulverizing the kelp into 40-mesh kelp powder, take 50g and place it in a container, mix it with deionized water in a weight ratio of 1:25, and extract it in an oil bath at 110°C for 4 hours;

[0033] (2) Concentration: filter and remove the kelp residue to obtain the extract, and concentrate the extract to a concentrated solution with a solid content of 40%;

[0034] (3) Alcohol precipitation: add absolute ethanol to the concentrated solution, after mixing evenly, the final concentration of ethanol is 75% of the volume fraction of the mixture, let stand at 2°C for 8 hours, filter and remove the supernatant, and polysaccharides precipitate;

[0035] (4) Drying: Freeze-dry the polysaccharide precipitate to obtain the target product, and the obtained product number is laminarin 2#.

[0036] Laminarin 2# is a light brown powder without fishy smell, and the yield is 6.5%.

Embodiment 3

[0038] (1) Extraction: After pulverizing the kelp into 60-mesh kelp powder, take 50g and place it in a container, mix it with deionized water in a weight ratio of 1:30, and extract it in an oil bath at 120°C for 3 hours;

[0039] (2) Concentrate: filter and remove the kelp residue to obtain the extract, and concentrate the extract to a concentrated solution with a solid content of 45%;

[0040] (3) Alcohol precipitation: add absolute ethanol to the concentrated solution, after mixing evenly, the final concentration of ethanol is 80% of the volume fraction of the mixture, let stand at 3°C ​​for 6 hours, filter and remove the supernatant, and polysaccharides precipitate;

[0041] (4) Drying: freeze-dry the polysaccharide precipitate to obtain the target product, and the obtained product number is laminarin 3#.

[0042] Laminarin 3# is a yellow-brown powder with no fishy smell and a sweet aroma. The yield is 6.2%.

Abstract

The invention discloses a laminarin. The laminarin is extracted and obtained by the following method: smashing kelp and then adding water, and extracting for 2-5 hours at the temperature of 105-125 DEG C; filtering to obtain extract, and concentrating the extract so as to obtain a concentrated liquid in which the content of solid substances is 35-45%; adding ethanol in the concentrated liquid forevenly mixing, and then standing for 4-12 hours at the temperature of 0-4 DEG C, and filtering so as to obtain polysaccharide precipitate; and carrying out freeze drying to obtain the laminarin. The laminarin the mass of which is 0.01-1.0% of pipe tobaccos is prepared into a solution, and then the laminarin solution is added in the pipe tobaccos or a filter tip through a spraying mode, thereby effectively reducing the content of free radical in main steam smoke of cigarette and also improving the smoking quality of cigarette, wherein the content of the free radical is reduced by more than 18%. The laminarin has the functions of reducing stimulation effect on nasal cavity, throat and the like, leading smoke to be smooth, leading mouth feel to be soft and maintaining aroma, and has no any side effects. The laminarin has no fishy smell, high extraction efficiency and low cost, and is easy to obtain.

Description

technical field [0001] The invention relates to the field of extraction of effective components of marine plants, in particular to a laminarin and its extraction method and application. Background technique [0002] Epidemiological surveys show that smoking can cause many human diseases, such as lung cancer, bronchitis, emphysema, oral cancer, bladder cancer, etc., and free radicals are one of the important causes of various diseases. During the smoking process, the smoke will produce alkoxy radicals RO·, alkyl radicals R·, quinone / semiquinone free radicals, polycyclic aromatic hydrocarbon free radicals, etc., which directly or indirectly attack cell components and cause certain damage to the body. As smoking and health issues have attracted more and more attention, reducing the free radical content in cigarette smoke has become one of the key research topics for cigarette harm reduction. The development and utilization of efficient and non-toxic free radical scavengers is a...
