The Eggplant (Solanum melongena), also known as Aubergine or Brinjal, is a warm-season crop in the Solanaceae producing large, glossy, egg-shaped fruits that are a cornerstone of Mediterranean, Middle Eastern, South Asian, and East Asian cuisines. From the deep purple Italian globe to the slender Japanese variety to the tiny Thai pea eggplant, the species displays remarkable diversity in shape, size, and color.
• Called "eggplant" because the original cultivated forms were white, oval, and egg-sized — literally looking like white eggs hanging on a plant
• Also known as "aubergine" (French/British) and "brinjal" (South Asian/ South African)
• The species name "melongena" means "mad-apple" — from the Italian "mela insana," reflecting the Renaissance belief that eating eggplants caused insanity
• Botanically a berry (like tomatoes), culinarily used as a vegetable
• Raw eggplant is bitter and spongy; cooking transforms it into silky, creamy, meaty perfection
• Over 1,500 cultivars exist worldwide, from long and thin to round and massive
• First domesticated in the region spanning India, Bangladesh, and Myanmar, approximately 2,000 to 3,000 years ago
• Cultivated in India since at least 300 BCE — mentioned in ancient Sanskrit texts
• Introduced to China by the 4th century CE, where it became a major crop
• Reached the Mediterranean via Arab traders in the 8th century
• Medieval Europeans called it "mad-apple" (mela insana) and feared it was poisonous
• Brought to the Americas by Spanish and Portuguese colonists
• Thomas Jefferson grew eggplants at Monticello in the late 1700s
• The genus Solanum contains approximately 1,500 to 2,000 species
• China produces over 60% of the world's eggplants — approximately 37 million tonnes annually
Plant:
• Erect, bushy, 60 to 150 cm tall
• Green to purple stems, sometimes with sparse spines
Leaves:
• Large, ovate to broadly elliptical, 10 to 25 cm long and 5 to 15 cm wide
• Green, sometimes with purple tints, with coarse hairs
• Lobed or entire margins
Flowers:
• Large, showy, five-lobed, 3 to 5 cm across
• Purple to violet, sometimes white, with a bright yellow central cone of stamens
• Self-pollinating but benefit from insect visits
Fruit (botanically a berry):
• Extremely variable across cultivars:
• Globe: large, round to teardrop, 10 to 20 cm, deep purple (Italian type)
• Japanese/Chinese: long, slender, cylindrical, 15 to 30 cm, purple or white
• Indian: small to medium, round or oval, purple, green, or striped
• Thai pea eggplant: tiny, round, green, 1 to 2 cm
• White egg: oval, white, 5 to 10 cm — the original form
• Skin: glossy, smooth, in colors from deep purple to lavender, green, white, orange, or striped
• Flesh: creamy white, spongy when raw, silky when cooked, with numerous small, soft seeds
Seeds:
• Small, flat, cream to brown, 2 to 3 mm
• Edible — tender in young fruits
Per 100 g raw eggplant:
• Energy: approximately 25 kcal
• Carbohydrates: 5.9 g (including 3.0 g fiber)
• Protein: 1.0 g
• Vitamin C: 2.2 mg
• Vitamin K: 3.5 mcg
• Potassium: 229 mg
• Manganese: 0.232 mg
• Folate: 22 mcg
Phytochemicals:
• Nasunin — an anthocyanin antioxidant found in the purple skin that protects brain cell membranes from free radical damage
• Chlorogenic acid — a potent antioxidant and anti-inflammatory compound
• Contains dietary fiber that supports digestive health
• The spongy flesh absorbs flavors and oils during cooking
• Low in calories when not fried, but fried eggplant absorbs significant oil due to its spongy texture
Planting:
• Start seeds indoors 8 to 10 weeks before last frost
• Germination at 25 to 30°C in 7 to 14 days
• Transplant after all frost danger when soil is warm (18°C+)
• Space 45 to 60 cm apart in rows 75 to 90 cm apart
Site:
• Full sun — minimum 6 to 8 hours
• Well-drained, fertile soil, pH 5.5 to 6.8
• Consistent warmth — eggplants are more heat-demanding than tomatoes
Care:
• Keep soil consistently moist
• Stake or cage plants to support heavy fruit
• Side-dress with compost when fruits begin to form
• Flea beetles are a common pest — use row covers or organic controls
Harvest:
• Harvest when skin is glossy and fruit is firm
• Press gently — ripe eggplant springs back; overripe fruit leaves a dent
• Harvest before skin turns dull — this indicates overripeness
• Cut from the plant with pruners — stems are tough
Preparation tips:
• Salting sliced eggplant for 30 minutes draws out moisture and bitterness (less necessary with modern cultivars)
• Grilling or roasting reduces oil absorption compared to frying
• Baba ganoush — smoky Middle Eastern dip of roasted, mashed eggplant with tahini and lemon
• Moussaka — the iconic Greek baked casserole with eggplant, meat, and béchamel
• Parmigiana di melanzane — Italian layered dish with fried eggplant, tomato, and mozzarella
• Ratatouille — French Provençal vegetable stew
• Baingan bharta — Indian smoky roasted eggplant mash with spices
• Sichuan eggplant (yu xiang qie zi) — Chinese sweet, sour, and spicy eggplant
• Tempura — Japanese battered and deep-fried eggplant
• Grilled eggplant slices with olive oil and herbs
• Stuffed eggplant — filled with meat, rice, or grain mixtures
• Thai green curry with eggplant
• Baba ganoush, caponata, and various dips
• Roasted and mashed as a base for vegetarian dishes
• Eggplant "bacon" — thinly sliced, smoked, and crisped as a vegan alternative
재미있는 사실
The original eggplant that gave the species its English name was small, oval, and white — it literally looked like a white chicken egg hanging from a bush. When the deep purple Italian varieties became popular, the name "eggplant" stuck, even though modern purple eggplants look nothing like eggs at all.
