The invention discloses a
caffeine-free tea-flavored concentrated solution, and relates to the field of
food processing. The
caffeine-free tea-flavored concentrated solution comprises an
aroma extracting solution A and a taste concentrated solution B. The
aroma extracting solution A and the taste concentrated solution B are compounded, blended and refined to prepare the
caffeine-free tea-flavored concentrated solution. The
aroma extracting solution A is prepared through the steps of
raw material treatment, low-temperature vacuum steam extraction and condensation collection, and the taste concentrated solution B is prepared through the steps of Roebos tea pretreatment,
water extraction concentration and enzymolysis
synergy. According to the caffeine-free tea
flavor concentrated solution, through the synergistic effect of
supercritical carbon dioxide fragrance removal and natural caffeine-free Roibos tea, the caffeine content of a final product is lower than the
detection limit and is far lower than the residue level of a traditional method. The low-temperature vacuum steam extraction avoids degradation of heat-sensitive aroma components, and the condensation collection technology is combined, so that the
retention rate of volatile aroma components is high and is obviously superior to that of a
supercritical carbon dioxide method.
