  • Patent number: 5211979
    Abstract: 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<1.1wherePY=2.94*y+2.1*x+16.6*y.sup.2 +2.7*x.sup.2 +14.6*xy-0.26wherein 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]<0.35either [P]<0.40 or [P]<0.65and [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.

  • Patent number: 5194273
    Abstract: A process is described for the preparation of laminated doughs, wherein the laminated dough has a number of fat layers having a different thickness. Such a dough is obtained by a process wherein the total amount of lamination fat is divided over several lamination steps. The invention is also concerned with a laminated dough, optionally in frozen condition and with baked products, obtained after baking of the dough.

  • Patent number: 5039544
    Abstract: A fatty composition comprising fat essentially consisting of a blend of one or more non-digestible polyol fatty acid polyesters and glyceride fat, wherein the fat comprises from 25% to 75% by weight of the polyol fatty acid polyesters, the blend of the polyesters having a slip melting point of between 35.degree. and 50.degree. C. and the fatty composition having an S.sub.20 in the range of 400 to 1400 g. The fatty composition can advantageously be used in the preparation and baking of dough, in particular layered dough. Layered dough product prepared with the fatty composition display ample lift upon baking. Another aspect of the invention is the use of a fatty composition in the preparation of layered dough. Yet another aspect of the invention is a layered dough.
