Abstract
Processing methods and compositions of matter are disclosed for lipid fractions of sea cucumber intestinal mass and body wall tissue suitable for the healthfood industry and aquaculture feed pigment industry. A process and composition of matter description for obtaining a high protein de-lipidized, de-odorized meal is also disclosed.
Claims13
A process for the large-scale extraction of usable lipid fractions from sea cucumber tissue comprising:
- a. extraction of guts of sea cucumber by hand or machine
- b. an acidifying step of a pH of between 4 to 5.5 of the sea cucumber gut material
- c. a step of drying the acidified sea cucumber gut material
- d. extracting total lipid fraction from acidified dry gut material by either hexane, liquefied propane, super-critical carbon dioxide, or combinations of the above.
A process for the large-scale extraction of usable lipid fractions from sea cucumber tissue comprising:
- a. extraction of guts of sea cucumber by hand or machine,
- b. acidifying the guts to a pH between 4 and 5.5
- c. extraction of total carotenoid lipid fraction from the acidified sea cucumber guts with acetone or
- b. extraction of total sea cucumber carotenoid lipid fractions into an edible oil by a "hot oil" industrial process.
A method for pigmenting fishes in need of same by the inclusion of sea cucumber carotenoid lipid fraction into diets as an additional component of such diet.
A method of obtaining a sea cucumber lipid fraction containing Omega-3 fatty acids and no carotenoids by:
- a. contacting sea cucumber carotenoid bearing lipid fraction with activated clay under vacuum and heat
- b. separating and extracting clay fraction with acetone to obtain concentrated carotenoid fraction
- c. separating clay/carotenoid fraction from remaining lipid fraction to obtain a carotenoid-free lipid fraction.
A composition of matter comprising a carotenoid lipid fraction obtained through acetone extraction of fresh acidified sea cucumber gut material.
A composition of matter comprising sea cucumber lipid fractions with no carotenoid material obtained by the following methods:
- a. contacting red carotenoid-bearing sea cucumber lipid fraction with activated clay or similar suitable material or material which adsorbs the pigments
- b. separating such activated clay from remaining lipid fraction solution which is essentially free of carotenoids.
A method of obtaining an essentially odorless and tasteless proteinaceous sea cucumber gut meal which is dry and free of lipid fractions obtained by extracting sea cucumber gut material with solvents to remove total lipids, and drying residue to less than 10% moisture.
A composition of matter consisting of dry proteinaceous de-lipidized gut material of the sea cucumber Cucumaria frondosa extracted by the following methods:
- a. extracting guts from sea cucumber organism and drying such sea cucumber gut material
- b. extraction of lipid fractions by means of solvent
- c. drying of solvent free material.
