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 comprising a blend of at least 25% or at least 30% of the said 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 comprising the fat base co
