Product Overview
Lemons are one of the most widely traded citrus fruits globally, valued for their high acidity, refreshing flavor, and versatility. They are a key commodity in both fresh and processed markets, extensively used in culinary, beverage, and industrial applications. Their consistent demand and year-round availability make lemons an essential product in retail and food service sectors.
Key Characteristics
Lemons are oval to oblong fruits with a bright yellow rind when mature. The skin may be smooth or slightly textured depending on the variety. The flesh is pale yellow, segmented, and highly juicy with a strong acidic flavor. Lemons typically contain seeds, although seedless varieties exist. They are non-climacteric fruits and do not ripen further after harvest.

Lemons are rich in vitamin C and provide antioxidants that support immune health. They contain small amounts of dietary fiber and minerals such as potassium. Their high citric acid content contributes to their preservative and culinary uses.
Seasonality and Origin
Lemons are grown in subtropical and Mediterranean climates. Major production regions include the United States (California and Arizona), Mexico, India, Spain, and Argentina. Due to multiple harvest cycles and global production, lemons are available year-round in international markets.
