Abstract
Yerba Mate is a popular tea beverage produced and consumed in the South American countries of Argentina, Brazil, Chile, Paraguay, and Uruguay, and is processed from the leaves and stems of Ilex paraguariensis A. St.-Hil., a perennial shrub from the Aquifoliaceae family. Production occurs in six stages: harvesting older leaves and small stems, roasting by direct fire, drying under hot air, milling to specified size, aging to acquire optimal sensory attributes, and final packaging. While grown and consumed for centuries in South America, its popularity is increasing in the United States because of demand by consumers for healthier, more natural foods, its filling a niche for a different type of tea beverage, and for Yerba Mate's potential health benefits - antimicrobial, antioxidant, antiobesity, anti-diabetic, digestive improvement, stimulant, and cardiovascular properties. Cultivation, production and processing may cause a variation in bioactive compounds biosynthesis and degradation. Recent research has been expanded to its potential use as an antimicrobial, protecting crops and foods against foodborne, human and plant pathogens. Promising results for the use of this botanical in human and animal health has prompted this review. This review focuses on the known chemical composition of Yerba Mate, the effect of cultivation, production and processing may have on composition, along with a specific discussion of those compounds found in Yerba Mate that have antimicrobial properties.
Yerba mate es una infusión popular producida y consumida en Argentina, Brasil, Chile, Paraguay y Uruguay. Se procesa a partir de hojas y tallos de Ilex paraguariensis A. St.-Hil., un arbusto perenne de la familia Aquifoliaceae. El procesamiento ocurre en seis etapas: recolección de hojas maduras y tallos pequenos, tostado por fuego directo, secado por aire caliente, molienda, envejecimiento (dependiendo de los atributos sensoriales requeridos), y embalaje final. Si bien la yerba mate se ha cultivado y consumido por siglos en América del Sur, su popularidad en los Estados Unidos ha aumentando debido a la demanda por bebidas saludables y alimentos más naturales y por los potenciales beneficios para la salud de la yerba mate (antioxidante, antimicrobiano, acción contra la obesidad y diabetes, digestivo, estimulante). La yerba mate también se ha investigado como agente de prevención y causa de algunos tipos de cáncer, causando controversia entre investigadores. Investigaciones recientes han ampliado el espectro de uso de la yerba mate como agente antimicrobiano, protección de cultivos y acción contra patógenos transmitidos por alimentos. Resultados prometedores para el uso de esta planta en la salud humana y animal han llevado a esta revisión. Esta revisión se centró en la composición de la yerba mate, y el efecto que el cultivo y el procesamiento puede tener sobre sus propiedades.
