Abstract

The invention discloses an iris extract. The preparation steps include: (1) smashing fresh iris leaves and soaking them in deionized water, and obtaining soaking liquid and soaking residue after soaking; (2) extracting the soaking liquid with glyceryl triacetate, extracting solution under reduced pressure to obtain solution A; (3) soak the soaking residue in the compound enzyme hydrolyzate of cellulase, pectinase, citric acid, vitamin C, acetic acid and water, and obtain the enzymolysis liquid and enzymolysis residue after soaking , after enzymolysis, the liquid was concentrated under reduced pressure to obtain solution B; (4) the enzymolysis residue was subjected to microwave-assisted extraction, and the extractant was an ethanol solution of malic acid / potassium sorbate. Concentrate to obtain solution C; (5) Mix solution A, solution B and solution C to obtain iris extract. For cigarettes made of shredded tobacco containing the iris extract of the present invention, the contents of heavy metals Pb, Cd and tar in the flue gas released during normal combustion are significantly lower than those of cigarettes that do not contain the present invention, the harmfulness is weakened, and the beneficial effect is obvious .

Description

technical field [0001] The invention belongs to the technical field of tobacco additives, in particular to an iris extract and its application in cigarettes. Background technique [0002] Iris is a perennial herb widely distributed in China. Iris root is a plant of the family Iridaceae (Iris Iris tectorum), bitter, sweet, cold in nature. Growing around forests, wet watersides and hilly areas facing the sun. Iris has anti-inflammatory properties and has significant curative effects on asthma and throat diseases. As a traditional Chinese medicine, orris root contains flavonoids, volatile oils, saponins, and tannins. [0003] The microwave extraction process is realized by high-frequency electromagnetic waves penetrating the medium and directly reaching the inside of the plant material. Microwave radiation can be converted into heat energy to heat rapidly, so that the internal temperature of the cell rises rapidly, and a large amount of water inside the cell evaporates, the...
