ANTIOXIDANT POTENTIAL, PHENOLIC CONTENT, AND NITRATE/NITRITE CONTENT IN VARIOUS LETTUCE VARIETIES

---

Ten lettuce varieties are analyzed for antioxidant activity, total phenolic,nitrate, and nitrite contents, and the effects of harvest maturi ty andcold storage in selected varieties are determined. Antioxidant activityand total phenolic content (TPC) are the highest in Red Oak, RedCoral, Red Rapids, and Grand Rapids; intermediate in Green Oak,Green Cos, and Frillice Iceberg; and the lowest in Butterhead, MiniGreen Cos, and Head lettuce. Nitrate content is the highest in RedCoral, while the other 9 varieties have comparably lower contents.Nitrite content is inadequate and does not differ with variety. Harvestmaturity of 45 days after transplanting (DAT) produced the highestantioxidant activity and TPC, much higher in Red Bowl and RedButterhead varieties than in Mini Green Cos, Butterhead, FrilliceIceberg, and Green Big Bowl varieties. Storage at 8oC for 21 days hasno remarkable effects on antioxidant activity, TPC, nitrate, and nitritecontents. Stored Red Bowl lettuce has higher antioxidant activity andTPC than Butter-head and Green Big Bowl varieties. Nitrate contentdecreases at the end of storage, while nitrite content is below 1mg/kg FW during the entire storage period, regardless of variet
