Abstract
Abstract The invention relates to emulsions, particularly low-calorie emulsions containing from 30-60 percent of fat, especially those of the water-in-oil type. The emulsions are stabilized by partial glycerides of both saturated and unsaturated fatty acids, particularly monoglycerides. The proportion of unsaturated fatty acid partial glycerides dominates the proportion of saturated fatty acid partial glycerides and the proportion of stearic acid partial glyceride dominates the remainder of saturated fatty acid partial glycerides.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
96 words
AN IMPROVED EDIBLE EMULSION, WHICH IS A LOW CALORIE FAT SPREAD OF THE WATER-IN-OIL TYPE, HAVING IMPROVED MICROBIOLOGICAL STABILITY AND ORGANOLEPTIC PROPERTIES CONSISTING ESSENTIALLY OF 30-60 PERCENT OF A FATTY PHASE, AN AQUEOUS PHASE AND AN IMPROVEMENT EMULSIFIER SYSTEM THEREFOR, SAID IMPROVED EMULSIFIER SYSTEM CONSISTING ESSENTIALLY OF SATURATED FATTY ACID PARTIAL GLYCERIDES AND UNSATURATED FATTY ACID PARTIAL GYLCERIDES, THE WEIGHT RATIO OF UNSATURATED FATTY ACID PARTIAL GYLCERIDES TO SAID SATURATED FATTY ACID PARTIAL GLYCERIDES BEING ABOUT 1.5-1 TO 10-1 AND WHERE SAID SATURATED FATTY ACID PARTIAL GLYCERIDES HAVE A DOMINANT PROPORTION OF STEARIC ACID PARTIAL GLYCERIDE.
Claim 2
Dependent Claim
96 words
AN IMPROVED EDIBLE EMULSION, WHICH IS A LOW CALORIE FAT SPREAD OF THE WATER-IN-OIL TYPE, HAVING IMPROVED MICROBIOLOGICAL STABILITY AND ORGANOLEPTIC PROPERTIES CONSISTING ESSENTIALLY OF 30-60 PERCENT OF A FATTY PHASE, AN AQUEOUS PHASE AND AN IMPROVEMENT EMULSIFIER SYSTEM THEREFOR, SAID IMPROVED EMULSIFIER SYSTEM CONSISTING ESSENTIALLY OF SATURATED FATTY ACID PARTIAL GLYCERIDES AND UNSATURATED FATTY ACID PARTIAL GYLCERIDES, THE WEIGHT RATIO OF UNSATURATED FATTY ACID PARTIAL GYLCERIDES TO SAID SATURATED FATTY ACID PARTIAL GLYCERIDES BEING ABOUT 1.5-1 TO 10-1 AND WHERE SAID SATURATED FATTY ACID PARTIAL GLYCERIDES HAVE A DOMINANT PROPORTION OF STEARIC ACID PARTIAL GLYCERIDE.
Claim 3
Dependent Claim
27 words
Emulsion according to claim 1, in which the weight ratio of unsaturated fatty acid partial glycerides to saturated fatty acid partial glycerides is from 1.6:1 to 8:1.
