tea extract as a liquid is often produced as a result of an extraction process
where by the fresh or dried tea leaves are immersed in an extraction fluid or
what is technically called a menstruum and agitated daily for a 2 to 4 week
period. The menstruum is a fluid that is designed to pull or draw out from the
green tea leaves the active constituents leaving behind the cellulose and the
fiber. A menstruum will more than likely have a solvent such as alcohol as part
of the solution.
Solvents
are selected for their ability to soften and break down the plant to facilitate
optimal extraction of the active and beneficial constituents. Digestible
solvents include water, alcohol, glycerine and vinegar. Non-digestible solvents
can be very efficient but are hard to remove after extraction without damaging
important and beneficial plant constituents. Still, traces of these
non-digestive solvents are left behind regardless of efforts undertaken to
remove them. Therefore, many consider them to be a poor choice for an herbalextract Manufacturers.
The
most popular and effective solvent is organically grown, distilled corn grain
alcohol. A very popular menstruum is made by mixing this corn grain alcohol
with filtered spring water. The raw herb material is often prepared in some way
for immersion in the menstruum. The formal term for this preparation is the
comminution of the herb material.
