A flavor-enhanced beverage includes an added amount of pyroglutamic acid or a salt thereof. The pyroglutamic acid may be in the form of L-pyroglutamic acid, D-pyroglutamic acid, monosodium L-pyroglutamate, monosodium D-pyroglutamate, or a mixture thereof. Both ready-to-drink beverages (such as fruit juices, vegetable juices, coffee, tea, carbonated soft drinks, energy drinks, sports drinks, dairy, and low calorie drinks) as well as concentrated beverages used for the preparation of ready-to-drink beverages benefit from the addition of the pyroglutamic acid. The addition to a beverage product may be in an amount of up to about 3,000 ppm of pyroglutamic acid or a salt thereof, in concentrates, or up to about 300 ppm in ready-to-drink beverages.
