  • Process for reducing spoilage of sterilized liquid products
    Patent number: 5800850
    Abstract: Spoilage of heat-sterilized liquid food products is reduced by preparing the liquid food product, prior to sterilization, by mixing an enzymatically-modified phospholipid composition, particularly an enzymatically-modified phospholipid composition having a degree of conversion of greater than 90%, with the liquid food product. Liquid food products which may be so treated include, in particular, coffee, tea, or cocoa beverage-component solids which provide beverage products. Additionally, an enzymatically hydrolyzed phospholipid composition having a degree of conversion greater than 90% may be obtained by hydrolyzing phospholipids in an aqueous medium, wherein the amount of water is greater than one part per part phospholipids, under agitated conditions so that a degree of conversion greater than 90% is obtained.
