The application discloses a white tea hydrolat intelligent segmentation collection method based on characteristic
aroma distillation kinetics identification, comprising the following steps: establishing the
distillation kinetics curve of
linalool,
geraniol and phenylacetal by standardized
distillation and high-frequency GC-MS detection; scientifically identifying the "composite high-efficiency distillation dynamic window" based on the comprehensive
aroma index of weighted calculation; realizing intelligent segmentation collection through flow
path switching according to the kinetic window parameters, and obtaining high-composite-
aroma-purity hydrolat and high-
linalool hydrolat respectively, and the aroma profile can be recombined and customized. The total content ratio of the three characteristic components in the obtained high-composite-aroma-purity hydrolat to the total amount of volatile aroma components is significantly improved, and the sensory
score is excellent; the content and relative content of
linalool in the high-linalool hydrolat are at a high level. The application realizes accurate enrichment of aroma components, improves the concentration of core components, and the product has pure aroma, batch stability, and is suitable for the fields of
cosmetics, functional foods and the like.
