  • Enzymatic transesterification starting from high erucic cruciferae oils
    Patent number: 5508048
    Abstract: High erucic cruciferae oils are interesterified with C.sub.16 or higher fatty acids or derivatives thereof. The use of a 1,3-selective lipase leads to the introduction of the fatty acid groups in the 1,3-positions. The liberated erucic acid (derivative) can be hydrogenated; the behenyl acid (or derivative) thus formed can be recirculated to provide at least 50% of the behenyl acid (derivative) needed in the process. The products obtainable by these processes, display good anti-blooming properties.

    Patent number: 4876107
    Abstract: Substitute milk fat especially as a replacement fat in infant formulations comprises 2-saturated glycerides especially 2-palmitic acid glycerides, in which the 1, 3 positions are randomly occupied substantially by different shorter chain and/or unsaturated fatty acids. These glycerides are prepared by selective rearrangement of glycerides using 1, 3-regiospecific lipase enzymes as rearrangement catalysts, preferably in acidolysis rearrangement using unsaturated acid or alkyl ester thereof.

  • Hard fat replacer and chocolate containing same
    Patent number: 4283436
    Abstract: Hard fat replacers, particularly for cocoa-butter, are provided comprising mixtures of mid-fraction from palm oil and at least 85% pure SOS, POS or SOS/POS. SOS is 1,3-distearyl-2-oleyl glycerol and POS is 1-palmityl-2-oleyl-3-stearyl glycerol. Using these hard fat replacers hardened milk chocolate and plain chocolate suitable for tropical use can be prepared as well as excellent normal plain and milk chocolates.

  • Chocolate having defined hard fat
    Patent number: 4276322
    Abstract: Chocolate is provided containing a hard fat comprising a mixture of a natural, high POP/POS/SOS-fat and a narrowly defined SOS/POS-fat. The hard fat lies within an area defined in FIG. 18, 19 or 20; in the absence of the SOS/POS-fat, the hard fat lies outside the area. Particular mixtures are also claimed for use as hard fats. Palm mid-fraction is a preferred natural, high POP/POS/SOS-fat.
