Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Thermodynamics of the lipase-catalyzed esterification of glycerol and n-octanoic acid in organic solvents and in the neat reaction mixture.[Reference:
WebLink]
METHODS AND RESULTS:
Short and medium-chain triacylglycerols, namely tributyrin (
1,2,3-tributyrylglycerol) and tricaprylin (1,2,3-tri-octanoylglycerol,1,2,3-Tri-n-Octanoylglycerol ), were interesterified with macadamia oil using an immobilized lipase as biocatalyst. Both normal phase (silica column; NP SIL ) and reverse phase (ODS column) HPLC with evaporative light scattering or mass spectrometric detection were used to separate and identify the newly-synthesized, structured lipid products. The normal phase method separated the structured lipid triacylglycerols on the basis of their regioisomeric-structures. Analysis of the structured triacylglycerols by a non-aqueous, reverse-phase method separated the regioisomeric triacylglycerols based on their total carbon number.
CONCLUSIONS:
From these analyses, it was found that of the triacylglycerol species produced by interesterification of macadamia nut oil with tributyrin or tricaprylin 77.6 and 94.1%, respectively, were structured lipid products.
