Low-temperature vacuum extraction (LT)
Extraction under low temperature and reduced pressure limits the loss of heat-sensitive aroma compounds — for formulations where the scent itself matters.
TECHNOLOGY

How we extract, what we record, and which documents come with the material.
METHOD
Extraction methods
The same rose yields different things depending on how it is handled. We supply the method that fits your purpose.
Steam distillation (SD)
The classic method yields a clear, stable rose water with little batch-to-batch variation — well suited to high-volume lines.
Concentration
Concentrating the rose water raises the level of active constituents, so a small dosage can carry the concept.
Low-temperature drying
Petals sorted right after harvest are dried at low temperature to hold colour and scent.
QUALITY
Quality control
Checked and recorded in four stages.
QC 01
Incoming check
Petals are checked for foreign matter and damage during sorting.
QC 02
Process log
Input quantity, temperature and time are logged for every batch.
QC 03
Composition & microbiology
Appearance, pH and microbiological items are managed.
QC 04
Release check
Packaging and labelling are verified, then released with the report.
PRODUCTION
Damask rose water
production process
Managed in five stages, from material preparation through to packing and release.
STEP 01
Material preparation
The condition of the harvested rose is checked, and foreign matter and damaged flowers are removed.
STEP 02
Extraction by method
LT is extracted under low temperature and reduced pressure; SD is produced by steam distillation.
STEP 03
Cooling and recovery
Vapour from the process is cooled and condensed to recover the rose water.
STEP 04
Quality check
Each production batch is checked against the ingredient specification and the result recorded.
STEP 05
Packing and release
Prepared to the pack size for each product, then released after checking labelling and packaging.
