Beschreibung
Zusammenfassung:	Un extracto vegetal que comprende al menos uno de ciclo-alanil-glutamina, ciclo-alanil-alanina, ciclo-seril-tirosina, ciclo-glicil-leucina, ciclo-glicil-triptófano, ciclo-valil-valina, ciclo-triptofanil-tirosina, ciclo-leucil-triptófano y ciclo- fenilalanil-fenilalanina a una concentración de 10 μg/100 g/Bx o más, donde el extracto vegetal es un extracto de té, un extracto de soja, un extracto de malta o un extracto de sésamo y la cantidad total de dicetopiperazina (o dicetopiperazinas) por Bx es de 900 μg/100 g/Bx o más. Provided are a diketopiperazine mixture suitable for mixing with a food or drink and a method for producing the mixture. High-temperature and high-pressure treatment of plant peptides in a liquid allows production of a plant extract containing a high concentration of diketopiperazines including cyclo-leucyl-leucine and cyclo-leucyl-phenylalanine. The present invention can provide diketopiperazines having excellent flavor derived from a plant natural product and can produce a food or drink provided with the functions of the diketopiperazines by directly mixing the diketopiperazines with the food or drink.
