Cardamom seeds
(Seeds of Elettaria cardamomum and related species)
Description
Cardamom seed is the dried, aromatic seed from the capsules of Elettaria cardamomum (green cardamom) or, less commonly, Amomum spp. (black cardamom).
The seeds are small, dark brown to black, contained inside trilocular capsules (pods).
They deliver an intense warm, spicy, fresh, slightly citrus and resinous flavour and are used as a culinary spice in sweet and savoury preparations, beverages and spice blends.
Cardamom seeds can be used whole, crushed or ground, and are often preferred over whole pods when a more concentrated and uniform flavour is needed.
Indicative nutritional values per 100 g
(dried cardamom seeds; approximate values)
Energy: 300–320 kcal
Protein: 10–11 g
Carbohydrates: 65–70 g
sugars: 2–3 g
Lipids: 6–7 g
SFA (first occurrence): about 1–1.5 g
MUFA: ~1 g
PUFA: ~2–3 g
TFA: negligible
Dietary fibre: 20–30 g
Minerals: potassium, magnesium, phosphorus, calcium (variable amounts)
At typical culinary use levels (≈1–3 g per serving), the nutritional contribution is modest; the main value is aromatic and functional.
Key constituents
Essential oil (main active fraction), typically 3–8% of the seed:
1,8-cineole (eucalyptol)
α-terpinyl acetate
linalool
limonene and other monoterpenes
Phenolic compounds and tannins.
Carbohydrates and dietary fibre (structural polysaccharides).
Proteins in moderate amounts.
Minerals (K, Mg, Ca, P) in trace to moderate levels.
Production process
Cultivation and harvesting of cardamom plants in tropical, often high-altitude regions.
Harvest of capsules when still green or at the appropriate ripening stage.
Drying of capsules in the sun or mechanical dryers to stabilise moisture and preserve volatile oil.
Seed extraction (for “cardamom seed” products):
mechanical opening or splitting of dried capsules;
separation of seeds from the husk.
Cleaning and grading to remove foreign matter and undersized seeds.
Optional grinding under low-heat conditions to produce cardamom seed powder.
Packaging in aroma- and moisture-protective materials (bags, cans, jars).
Production under GMP/HACCP, with controls for microbiology, foreign bodies, pesticide residues and heavy metals.
Physical properties
Appearance: small, wrinkled, dark brown to black seeds; ground seed appears as a brown, fine powder.
Aroma: intense, spicy, warm, fresh, slightly mentholated and citrus-like.
Taste: warm, aromatic, slightly sweet and citrus, with balsamic notes.
Moisture: typically below 12% for stability.
Solubility: seeds are insoluble in water; essential oil components are extractable in hot water, fat and alcohol.
Bulk density: moderate, depending on particle size (lower for whole seeds, higher for powder).
Sensory and technological properties
Very high aroma impact: small amounts strongly characterise foods and beverages.
Can be used whole (for slow flavour release), cracked (for infusions) or finely ground (for uniform flavour distribution).
Essential oil provides a fresh, green, slightly camphoraceous note, typical of chai and Middle Eastern/Indian desserts.
Grinding increases surface area and improves flavour release but also accelerates aroma loss and oxidation.
Stable under moderate heat, though prolonged high-temperature cooking will reduce the top-note freshness.
Food applications
Bakery and confectionery: cakes, biscuits/cookies, buns, sweet breads, pastries, fillings, creams and custards.
Beverages: chai tea, spiced teas, flavoured coffee, cocoa drinks, herbal infusions, winter punches.
Savoury dishes: curries, rice dishes (e.g. basmati pilaf, biryani), stews, marinades and rubs for poultry and lamb.
Dairy products: flavoured yoghurts, lassi, ice creams, milk desserts.
Spice blends: garam masala, curry blends, masala chai mixes, Middle Eastern spice mixes.
Industrial foods: aromatised snacks, bakery goods, syrups, ready-to-drink teas and functional beverages.
Nutrition & health
Cardamom seed is rich in volatile terpenes and phenolic compounds, which contribute to antioxidant activity in vitro, though real-life effects at culinary doses are modest.
The high fibre content is nutritionally positive but only relevant at higher intakes than typical culinary usage.
Traditionally associated with digestive comfort, breath freshness and gastrointestinal well-being in herbal medicine; such claims are usually regulated and cannot be freely used on standard food labels.
Generally well tolerated by healthy consumers when used in normal culinary amounts.
Portion note
Typical uses:
1–3 g ground or crushed seed per recipe/serving (desserts, baked goods, curries).
1–2 g lightly crushed seeds per 200–250 mL of water for infusions and chai.
Higher inclusion levels strongly increase flavour intensity and can easily dominate other ingredients.
Allergens and intolerances
Cardamom seed is not a major listed allergen.
Rare idiosyncratic sensitivities to essential-oil components may occur in susceptible individuals.
Naturally gluten-free, unless cross-contaminated during processing.
In spice blends, other allergens (e.g., milk, soy, nuts, sesame) may be present and must be declared separately.
Storage and shelf-life
Store in a cool, dry place, away from heat, light and strong odours.
Prefer airtight containers to protect essential oils and limit moisture uptake.
Shelf-life:
whole seeds: typically 24–36 months with good aroma retention;
ground seed: typically 12–24 months, with faster aroma loss.
Main deterioration issues:
loss of aroma due to volatilisation and oxidation;
moisture uptake, leading to clumping and potential mould risk;
insect infestation if stored improperly.
Safety & regulatory
Considered safe at normal culinary levels.
Subject to general regulations for spices and dried herbs:
limits for mycotoxins, pesticide residues, heavy metals;
microbiological criteria for dried products.
Production and trade should follow GMP/HACCP, with full traceability of origin and processing steps.
Concentrated extracts or high-dose preparations may fall under food supplement or flavouring regulations.
Labeling
Typical designations:
“cardamom seed”
“cardamom (seed)”
In spice blends and processed foods: listed in the ingredients list in descending order of weight.
No intrinsic mandatory allergen from cardamom seed itself; any allergens from carriers or other ingredients must be declared.
Troubleshooting
Weak flavour in finished product:
seeds too old, poor-quality lot or insufficient dosage → use fresher/higher-quality seeds, grind just before use, adjust dosage.
Overly intense or “soapy/camphoraceous” taste:
over-dosage or very strong variety → reduce inclusion rate or blend with milder spices.
Loss of aroma during cooking:
long high-temperature exposure → add part of the cardamom later in the cooking process or as a finishing spice.
Clumping in powdered blends:
moisture uptake → improve packaging, control humidity, and consider flow aids where permitted.
Sustainability & supply chain
Cardamom is typically grown in tropical, often mountainous regions, sometimes in agroforestry systems under shade.
Key sustainability aspects:
soil and biodiversity management;
water use and erosion control in hilly plantations;
fair labour conditions and income for smallholder farmers.
Processing facilities must manage drying, cleaning and grinding efficiently, with responsible handling of wastewater and cleaning effluents.
Certifications (organic, fair trade, sustainability labels) may support responsible sourcing and traceability.
Main INCI functions (cosmetics)
(typically as “Elettaria Cardamomum Seed Extract” or “Elettaria Cardamomum Seed Oil”)
Fragrance component providing a spicy-fresh, aromatic note.
Skin-conditioning agent in some botanical formulations.
Used at low levels in creams, soaps, perfumes, deodorants and aromatherapy products to impart a warm, exotic scent.
Conclusion
Cardamom seed is a high-value spice ingredient with a unique, intense aromatic profile that enhances a wide range of sweet and savoury foods and beverages. It is used in small amounts yet has a strong sensory impact, making it a key component in many traditional cuisines and modern formulations. When sourced responsibly, processed under GMP/HACCP, and stored properly, cardamom seed offers a stable, aromatic and premium-quality ingredient for culinary and industrial applications.

Studies
It has antioxidant properties (1), contributes to lower blood pressure (2) and sedative properties (3).
Subs: Limonene, Fenchone, Valerianol (4), Kaempferol, Quercetin (5).
Cardamom oil serves as a grain protein potential by killing various life stages of wheat attacking insects, such as Tribolium castaneum and Sitophilus zeamais, through contact and fumigating action (6).
