The present invention is concerned with a fat composition comprising a mixture of one or more polyol fatty acid polyesters, which mixture exhibits Newtonian rheology at solid fat content of at least 15%, and with a fatty acid distribution which complies with the condition: PY<1.1 where PY=2.94*y+2.1*x+16.6*y2+2.7*x2+14.6*xy-0.26 wherein x=[P]-[M] and y=[S]-[P] and PY means predicted yield and which in the same time complies with each of the following conditions: [B]<0.35 either [P]<0.40 or [P]<0.65 and [L]<0.15, wherein [P] is the molar fraction of palmitic acid residues, [M] is the molar fraction of myristic acid residues and [S] is the molar fraction of stearic acid and longer saturated fatting acid residues, [B] is the molar fraction of lauric and shorter fatty acid residues, [L] is the molar fraction of saturated fatty acid residues having a carbon chain length of at least 20. The present composition displays newtonian rheology even when containing a substantial amount of solid fat, which is advantageous in the preparation of, e.g., flowable fat products. |
