摘要： This invention relates to a process for producing a tea extract. The process includes subjecting a first tea extract solution, which has been obtained from tea, to solid-liquid separation so that a turbidity becomes 200 NTU or lower when a concentration of non-polymer catechins is adjusted to 1 wt %, thereby obtaining a second tea extract solution in which a concentration of (A) non-polymer catechins is from 0.2 to 5 wt % and a concentration of non-polymer catechins in solid content is from 15 to 80 wt %; and then subjecting the second tea extract solution to a heat treatment at a temperature of from 95 to 140° C. for an F value of from 0.05 to 40 min.
