Process for the preparation of human milk fat substitutes

摘要

Disclosed are human milk fat (HMF) substitutes, processes for preparation thereof, uses thereof, and fat blends and formula containing the HMF substitutes. A fat base composition of the invention includes a mixture of vegetable-derived triglycerides, with less than 50% of the fatty acid residues bonded at the sn-2 position being saturated; and/or with the amount of saturated fatty acid residues bonded at the sn-2 position of the glycerol backbone less than about 43.5% of the total amount of the fatty acid residues. Typically, substantially all of the saturated fatty acids bonded at the sn-2 position of the glycerol backbone are palmitic acid residues. Also disclosed are substitute HMF compositions including a blend of at least 25% or at least 30% of the fat base composition of the invention with up to 75%, or respectively up to 70%, of at least one vegetable oil. Processes for preparing the fat base compositions and blend are also disclosed. Further disclosed are infant formulas including the fat base composition or substitute human milk fat composition.
