摘要:
Acetoglycerides are prepared in a solventless, single phase interesterification between triacetin and triglycerides bearing long C16 to C22 fatty acid residues by adding triglycerides bearing saturated C3 to C10 acid residues to the reaction mixture. The long acid residues may be hydrogenated before or after interesterification. In one embodiment, the C3 to C10 triglycerides are tripropionin, tributyrin, or mixtures of these; in another, these are triglycerides bearing C8 to C10 acid residues; and in a third, these are a mixture of tripropionin and/or tributyrin and C8 to C10 triglycerides. In preferred embodiments, the molar ratio of C16 to C22 triglycerides to triacetin and C3 to C10 triglycerides varies between 1:1 and 1:15, more narrowly between 1:3 and 1:12, and high temperatures are employed. The process diminishes catalyst use, obviates the need for high shear mixing, shortens reaction times, and simplifies purification steps.

摘要:
Fat mixtures enriched with triglycerides having long, saturated, preferably C16 to C22, fatty acid residues and short, preferably C2 to C4, acid residues are employed in edible compositions as low calorie fats. The preferred embodiments comprise mixtures of at least two triglycerides bearing long residues (e.g. stearyl) and short residues (e.g. acetyl or propyl). In one preferred embodiment, each triglyceride contains short chain residues which are different from those in the other triglyceride. In another preferred embodiment, at least a portion of the triglycerides have two different short residues. Methods of using the low calorie fats and food products incorporating them, particularly in coating, shortening and margarine products, are disclosed.

The fat composition for puff pastries of the present invention contains at least 30% by volume, based on the whole of the crystal aggregates, of crystal aggregates having a β'- or intermediate crystal form and a size exceeding 10 µm.
摘要:
A powdery or granular fat or oil composition in the form of a powder or granules having a water content of 15 % by weight or less, a maximum particle diameter of not greater than 10 mm, an average particle diameter of not greater than 5 mm and an angle of repose of not greater than 70 %. The composition is produced simply by mixing only a fat or oil, a base material capable of occlusion or absorption of the fat or oil and a liquid polyol at a temperature at which the fat or oil is molten.
摘要:
Triglycerides are esterified at the 1- and 3- positions with saturated, long chain fatty acids, such as stearic, and at the 2- position with a short chain acid, such as acetic. These triglycerides provide fewer calories than those triglycerides commonly present in foods. Food compositions which are lower in calories than the original compositions can thus be produced by replacing some or all of the fat with this type of triglyceride.
