Eucheuma denticulatum is presently cultivated in the Philippines, Indonesia, Western Central Pacific Islands and several other tropical countries. All of this is equivalent to determining the density of a rock and, seeing that it is 3. If extraction is done at boiling point without pressure it is usual to work between pH 4.
