Different quality of tobacco

1. Tobacco For Different Quality

2. Introduction: ★ General background of tobacco ( Nicotiana tabacum and Nicotiana rustica ). ★ Historical importance: origin in the Americas, spread to Europe and Asia ★ Role of tobacco in global economy, trade, and agriculture ★ Importance of quality differentiation in tobacco for various end uses (cigarettes, cigars, bidi, chewing, snuff, hookah).

3. Concept of Tobacco Quality: ★ Quality as determined by consumer preference (smokers, manufacturers, industry). ★ Importance of physical, chemical, and sensory attributes. ★ International standards for tobacco trade.

4. Classification of Tobacco Types By Quality: 1) Flue- cured virginia 2) Bidi Tobacco 3) Cigar Tobacco 4) Hookah/ Oriental Tobacco 5) Chewing Tobacco 6) Snuff Tobacco 7) Rustica Tobacco

5. Flue-Cured Virginia(FCV) Tobacco ★ High sugar, mild aroma, bright yellow leaves. ★ End use: cigarettes. ★ Grown in India (AP, Karnataka). 2) Burley Tobacco: ★ Light air-cured, low sugar, high nicotine. ★ Used in blends for cigarettes. 3) Oriental (Turkish) Tobacco: ★ Small leaves, sun-cured, aromatic. ★ Rich flavor , low nicotine. ★ Famous in Turkey, Greece.

6. 4) Cigar Tobacco: ★ Types: filler, binder, wrapper leaves. ★ Grown in Cuba, Dominican Republic, Nicaragua. ★ Dark air-cured or fermented leaves. 5) Bidi Tobacco: ★ Sun-cured, strong flavor . ★ Predominant in India (Gujarat, Madhya Pradesh). 6) Chewing and snuff Tobacco: ★ Dark, high nicotine. ★ Processed into moist snuff, dry snuff, khaini . 7) Hookah/ Chillum Tobacco: ★ Fermented and flavored (molasses, fruit). ★ Strong smoke, popular in Middle East and India.

7. Factors Determine Tobacco Quality: Genetic Factors: ★ Varietal differences in nicotine, sugars, leaf thickness. ★ Examples of quality-specific varieties. 2) Environmental Factors: 3.2 Environmental Factors ★ Soil fertility, rainfall, and temperature. ★ Influence of sandy vs. Clay soils on leaf texture. ★ Effect of altitude (aroma in Turkish tobacco). 3) Cultural practices: ★ Seedling raising and transplanting techniques. ★ Nutrient management (N, P, K and their role in quality). ★ Pest and disease management and its impact on cured leaf quality

8. 4) Harvesting and Curing Practices: Practices ★ Harvesting methods (priming vs. Stalk-cut). ★ Stages of leaf maturity for different qualities. ★ Curing methods: flue-curing, air-curing, fire-curing, sun-curing 5) Storage Conditions: ★ Proper fermentation and storage enhance aroma and flavor .

9. Quality Parameters Of Tobacco: 1) Physical Parameters: ★ Leaf size and shape. ★ Color (bright lemon, orange, brown, dark). ★ Texture (thin vs thick leaves). ★ Elasticity and flexibility of cured leaf. ★ Free from blemishes, pests, or mold . 2) Chemical Parameters: a) Nicotine Content: ★ Low nicotine - mild cigarettes. ★ Medium nicotine - balanced quality ★ High nicotine - bidi, chewing ,tobacco.

10. b) Sugars and Carbohydrates: ★ High sugar → mild flavor , good aroma. ★ Low sugar → harsh taste. C) Proteins and Nitrogen Compounds: ★ Affect burning quality and flavor . d) Aroma Compounds: ★ Formed during curing and fermentation. E) Moisture Content: ★ Ideal range: 12-15% for storage stability 3) Organoleptic Properties: ★ Taste, aroma, smoothness of smoke. ★ Irritation and aftertaste.

11. Grading Of Tobacco For Quality: ★ Based on position of leaf (lugs, cutters, leaf, tips). ★ Based on color (bright lemon, orange, red, dark). ★ Based on chemical composition (nicotine %, sugar %, aroma intensity). ★ Based on market standards set by Tobacco Board of India and international buyers.

12. Uses Of Different Quality Tobacco: ★ High-quality flue-cured → cigarettes. ★ Medium quality bidis, chewing, hookah. ★ Low quality / scraps snuff, industrial use. ★ By-products nicotine sulfate (insecticide), tobacco seed oil, tobacco dust (bio-pesticide).

13. Processing and Curing Method Affecting Quality: ★ Flue Curing gives bright lemon to orange color , cigarette quality. ★ Air Curing for cigar and chewing tobacco. ★ Fire Curing produces strong aroma, used in snuff, chewing blends. ★ Sun Curing – for oriental and hookah tobacco.

14. Challenges In Maintaining Tobacco Quality: ★ Climate variability affecting curing. ★ Pests and diseases. ★ Stringent international quality standards. ★ Health awareness reducing demand in some segments.

15. Quality Improvement Strategies: ★ Breeding for improved aroma, reduced nicotine, disease resistance. ★ Balanced nutrient management (N-K ratio). ★ Improved curing technologies (energy-efficient flue-curing barns). ★ Organic and low-nicotine tobacco production. ★ Precision farming and mechanization.

16. Conclusion: ★ Tobacco quality is determined by a combination of genetic, environmental, and processing factors. ★ Each type of tobacco serves a specific end use depending on its physical and chemical properties. ★ Proper cultivation, curing, grading, and storage practices are essential for producing high-quality tobacco to meet global demand.
