Abstract
Blends of wax-esters with beneficial health properties comprise: .gtoreq. two different wax-esters in amounts of 5-95% and each having m.pt -10.degree. C. to 80.degree. C. blend displaying m.pt: 15 to 45% while >80 wt % of wax-esters in blend have m.pt 20 to 60.degree. C.; wax-esters derived from linear alcohols and linear carboxyl acids either of them having .gtoreq.8 C-atoms.

- N20=5-80,
- N30=2-60 and
- N35=<20.
Food composition comprising a lipid phase, which is present for at least 10 wt % and which lipid phase comprises at least 20 wt % of a blend of wax-esters, said blend comprising at least two different wax-esters each present in amounts of 5-95 wt %, said individual wax-esters each having a melting point between -10 and 80.degree. C. while the blend displays a melting point between 15 and 45.degree. C. and at least 80 wt % of the wax-esters present in the blend having a melting point between 20 and 60.degree. C., the wax-esters being derived from (1) a saturated or unsaturated linear alcohol of at least 8 C atoms and a linear mono- or di-unsaturated carboxylic acid of at least 18 C atoms, the alcohol and acid each having an even number of carbon atoms or (2) a saturated or unsaturated linear alcohol of at least 8 C atoms and a linear polyunsaturated carboxylic acid with at least 18 C atoms and having at least 3 unsaturations.
Process for the preparation of blends of wax-esters of at least two different wax-esters each present in amounts of 5-95 wt %, said individual wax-esters each having a melting point between -10 and 80.degree. C. while the blend displays a melting point between 15 and 45.degree. C. and at least 80 wt % of the wax-esters present in the blend having a melting point between 20 and 60.degree. C., the wax-esters being derived from (1) a saturated or unsaturated linear alcohol of at least 8 C atoms and a linear mono- or di-unsaturated carboxylic acid of at least 18 C atoms, the alcohol and acid each having an even number of carbon atoms or (2) a saturated or unsaturated linear alcohol of at least 8 C atoms and a linear polyunsaturated carboxylic acid with at least 18 C atoms and having at least 3 unsaturations which comprise enzymically converting the fatty acid of at least 18 C-atoms and said alcohol of at least 8 C-atoms to said wax-ester blend.
