Abstract

Provided is a powdered green tea extract composition, including the following components (A) to (C): (A) non-polymer catechins; (B) quinic acid; and (C) a polysaccharide, wherein the powdered green tea extract composition has a volatile content of 5.6 mass % or less, wherein a mass ratio between the component (A) and the component (B), [(B)/(A)], is less than 0.2, wherein amass ratio between the component (A) and the component (C), [(C)/(A)], is 1.2 or more, wherein, when an absolute value (Δa*) of a difference between an a* value in an L*a*b* color system of the powdered green tea extract composition after storage under an atmosphere of 37° C. and 50% RH for 6 weeks and an a* value in the L*a*b* color system of the powdered green tea extract composition immediately after production is obtained, the Δa* of the powdered green tea extract composition is a value less than Δa* of a powdered green tea extract composition α which has the same mass ratio [(B)/(A)] as the mass ratio [(B)/(A)] of the powdered green tea extract composition, and which is free of the component (C), and wherein a change rate calculated by the following expression (2) is 5% or more: (Δa*−Δa₁*)/Δa*×100 (2) where Δa₁* and Δa* have the same meaning as Δa₁* and Δa* described in Description.
