  • Patent number: 5149560
    Abstract: This invention concerns a heat-resistant or thermally robust chocolate and method for making same. The inventive method provides a means of adding moisture to chocolate through use of lipid microstructure technology such as reverse micelle technology to form a stable water-in-oil emulsion, for example, hydrated lecithin. The stable water-in-oil emulsion is added to tempered chocolate during processing, and upon aging and stabilization, thermal robustness develops in the chocolate product. The heat-resistant chocolate of the instant invention is suitable for use in the same manner and for the same purposes for which ordinary chocolate is used. The invention provides a heat-resistant chocolate product having the desired taste, texture, mouth feel and other characteristics of ordinary chocolate.
