Flavors and fragrances are crucial in enhancing the quality of cigarettes, as they provide different aromas and tastes to achieve diversity in cigarette quality. In recent years, pursuing green, natural, safe, and eco-friendly products has become a mainstream trend among consumers. Therefore, natural flavors, especially those derived from plants, are more likely to be favored by people.
Advantages of Natural Flavors
Artificially synthesized cigarette flavors have been widely used in cigarettes due to their clear and targeted composition, strong specific effects, and good aroma characteristics. However, the drawback of synthetic flavors lies in their simple composition and single aroma profile. Therefore, a combination of multiple flavors is typically needed to create a complex cigarette flavor that meets quality requirements. Natural flavors, on the other hand, can overcome this limitation. Due to their diverse composition, natural flavors produce a wide range of aromatic compounds during the smoking process. While there may be some negative effects such as impurities, the overall aromatic effect of natural flavors is more rich and full-bodied compared to the single-component nature of synthetic flavors. As a result, natural flavors offer a unique and unparalleled fragrance that cannot be replicated. With the in-depth research on natural flavors, their application in the tobacco industry has gradually gained attention in China.
There are various categories of natural flavors used in cigarettes. For example: Tobacco Flower Extracts; Oriental Tobacco Flower Extracts; Waste Tobacco Leaf Extracts; Flavors obtained from soaked waste tobacco leaves; Fruits and Fruit Extracts; Herbal Extracts; Flavors obtained from herbs like luohan guo, Tie Guan Yin tea leaves, Qimen black tea, and Maofeng tea leaves and other extracts. These categories represent the different sources of natural flavors used in cigarettes.
1. Tobacco-derived flavors are a unique category among natural plant flavors
They are a mixture of volatile aromatic components extracted from the flowers, leaves, stems, roots, and fruits of tobacco plants. Different extraction methods yield various products such as essential oils, extracts, absolutes, and tinctures. Since they originate from tobacco, they can be directly used to enhance the aroma of cigarettes and tobacco sheets. These flavors have a realistic and natural scent, which can enhance the tobacco aroma, reduce off-notes, and improve the quality of cigarettes. They not only supplement the characteristic aromas of different types of tobacco but also have the effect of emitting the inherent fragrance of tobacco. Their effectiveness surpasses the use of various other tobacco flavors previously employed for blending.
2. Fruit-derived flavors
Fruit-derived flavors include lemon, lime, orange, kumquat, fig, dill, strawberry, jujube, and sour jujube. Researchers have conducted a comprehensive analysis of the aroma components of pineapple flavor used in cigarettes using GC/MS method. They identified a total of 45 compounds, including esters, alcohols, and acids, and evaluated their effectiveness in enhancing and moisturizing cigarettes. The results showed that pineapple flavor has a good effect on enhancing the aroma and moisture retention of cigarettes.
Researchers also extracted fresh tomatoes using the organic solvent reflux extraction method to obtain tomato extract. Through GC/MS analysis, they detected and identified 25 compounds, including higher fatty acids and esters. The results of cigarette flavoring experiments demonstrated that the alcohols in tomato extract enhanced the taste and increased the smoke concentration of cigarettes. It also improved the aroma quality of cigarettes.
3. Tea derived flavors
Red tea was found to contain characteristic aroma components such as trans-linalool oxide, linalool, methyl salicylate, nerolidol, phenylethanol, benzyl alcohol, terpinen-4-ol, and trans-2-hexenal. Cigarette flavoring experiments showed that the use of these flavors significantly enriched the tobacco aroma, increased sweetness, reduced irritation, and improved the aftertaste.
The GC/MS analysis of Tie Guan Yin tea stem extract identified a total of 58 compounds, including alcohols, ketones, esters, and acids. The results of cigarette flavoring experiments demonstrated that the use of these flavors significantly improved and enhanced the aroma quality and intensity of the tobacco blend. It made the smoke delicate, smooth, and moist, with a rich and prominent fragrance. It also reduced irritation and improved the aftertaste.
4. Plant derived from flower flavors
Plants that extract fragrances from their flowers include roses, jasmine, osmanthus, lilies, lavender, chrysanthemums, mimosa, cloves, yilan, bergamot, orange blossom, wild chrysanthemum, hops, and honeysuckle. From the extraction of fragrance from osmanthus flowers, GC/MS analysis revealed the presence of 24 aromatic compounds. Cigarette flavoring experiments showed that osmanthus essence enriched the tobacco aroma and improved its sweetness and delicacy. Hang-Bai-Ju (Chrysanthemum indicum) essential oil, tested through cigarette flavoring experiments, enhanced the quality of tobacco aroma, improved the aftertaste, and softened the smoke. By using supercritical fluid extraction technology to extract daisy volatile oil, GC/MS analysis detected a total of 45 volatile components such as limonene, linalool, dihydro linalool, and eugenol. Cigarette flavoring experiments demonstrated that the volatile oil increased the tobacco aroma, softened the smoke, reduced irritation, masked off-notes, and improved the smoking experience.
5. Plant derived from leaves flavors
Plants that extract fragrances from their stems and leaves include bay leaves, orange leaves, eucalyptus leaves, loquat leaves, and camphor leaves. Using ethanol extraction and adsorption chromatography, the fragrance components of loquat leaves were extracted and separated. GC/MS analysis identified 27 aromatic compounds, including ethyl palmitate, nerolidol, and dihydroactinidiolide. Cigarette flavoring experiments showed that these isolated compounds effectively masked off-notes in cigarettes, resulting in a smooth and delicate smoke aroma. By using conventional extraction methods, the fragrance components of bitter tea leaves were extracted and separated, yielding compounds such as 2,6-dimethylquinoline, 2,4,6-tributylphenol, tert-butylated hydroxytoluene, 2,4,6-triisopropylbenzophenone, and hexabenzene. It was found that this fragrance enhanced the delicacy and sweetness of the smoke in cigarettes and significantly affected the smoothness, concentration, richness, and harmony of the smoke aroma.
6. Seaweed Fragrances
Undaria pinnatifida extract was obtained using supercritical extraction. GC/MS analysis identified a total of 49 chemical components, including 29-isoyanosterol, palmitic acid, stearic acid, neophytadiene, oleic acid, myristic acid, linoleic acid, ethyl linoleate, and methyl linolenate. Cigarette flavoring experiments showed that the Undaria pinnatifida extract had the effect of reducing off-notes and irritants in cigarette smoke, increasing the sweetness of the smoke, and improving the mouthfeel.
Supercritical CO2 extraction of Enteromorpha prolifera was conducted, and GC/MS analysis identified a total of 37 components in the extract, including palmitic acid, myristic acid, stearic acid, arachidonic acid, (E)-9-octadecenoic acid, linoleic acid, and erucic acid. Cigarette flavoring experiments demonstrated that the Enteromorpha prolifera extract significantly reduced off-notes, imparted a milder smoke aroma, and increased the sweetness of the smoke.
7. Mushroom Fragrances
Volatile oil from Ganoderma lucidum mycelium was extracted using simultaneous distillation-extraction technique. GC/MS analysis revealed the presence of 39 chemical components, including linoleic acid, palmitic acid, linalool, anethole, furfural, and pyridine. Cigarette flavoring experiments showed that the volatile oil from Ganoderma lucidum mycelium had the effects of enhancing the sweetness of the smoke, reducing the dryness of the smoke, and improving the taste upon inhalation.
8. Herbal Fragrances
Ethanol extraction was used to obtain extracts from Scutellaria baicalensis, and GC/MS analysis revealed the presence of baicalin and other effective aromatic compounds. Cigarette flavoring experiments showed that the Scutellaria baicalensis extract had the effects of enhancing the aroma, softening the smoke, and improving the aftertaste.
From the Perilla frutescens, 33 volatile aroma compounds including Perillaldehyde, terpenes, esters, and ketones were extracted. Based on the composition, it is inferred that the Perilla frutescens extract can effectively improve the fragrance quality of cigarettes, enhance the richness of the smoke, harmonize the aroma, and reduce irritants.
