Brown skin, Brain fever, Refrigeration, Pesticides.
Litchis attract more myths than any fruit we sell. 🍒
This summer, we’re setting the record straight — swipe for what’s actually happening inside your litchi, and why the cold chain matters more than colour ever will.

Brown skin = spoiled?
MYTH: Brown skin means it’s gone bad.
FACT: Litchi skin is rich in anthocyanins, the pigments giving it colour. Once picked, the fruit loses moisture through transpiration, and as it dries, those anthocyanins oxidise and turn brown. Purely surface level. The flesh stays protected inside.
📌 Check the inside, not the outside.
Do pesticides get inside?
MYTH: Sprayed pesticides soak into the flesh.
FACT: The waxy pericarp acts as a barrier — residues like Cypermethrin or Chlorpyrifos mostly stay bound to the peel, especially on cart-bought fruit. Since peel is discarded before eating, risk is low, not zero.
📌 Test. Trace. Then eat.
The “brain fever” scare
MYTH: Litchis cause brain fever.
FACT: Real outbreaks occurred in malnourished children who ate unripe litchi seeds on empty stomachs. Those seeds contain hypoglycin A and MCPG, which block the body from making glucose from fat, triggering severe hypoglycemia in already undernourished kids. Ripe litchi, eaten normally, carries no such risk.
📌 Ripe + sensible = safe.
Does colour mean sweeter?
MYTH: Redder = sweeter.
FACT: Colour comes from anthocyanin response to sunlight and temperature , not sugar. Sweetness depends on cultivar, ripeness at picking, and freshness.
📌 Taste is chemistry, not pigment.
Does cold ruin litchis?
MYTH: Refrigeration kills flavour and texture.
FACT: Opposite. Litchi’s thin, porous pericarp has a high surface-area-to-volume ratio, so it loses moisture fast at room temp. Heat also speeds up respiration rate and enzymatic browning. Cold slows both, keeping fruit crisp longer.
📌 Heat is the enemy, not cold. That’s why we move litchis in temperature-con
