  • Patent number: 4490400
    Abstract: A spoonable tomato product and method of making the same comprising a water-in-oil emulsion component and a natural pulpy tomato solids component wherein said components are in amounts proportioned to provide a spoonable product which is stable during use and storage. The emulsion component contains at least about 60% w/w edible oil and the tomato component contains at least about 75% w/w natural pulpy tomato solids. The natural tomato solids impart a natural grainy, pulpy texture to the spoonable product. The emulsion component formulates a water-in-oil emulsion that imparts a spoonable consistency having the characteristics and stability similar to mayonnaise. These spoonable tomato products may be stored and used for an appreciable amount of time without experiencing rapid biodegradation or serious putrefaction. Thus, these spoonable tomato products are especially suitable for use in food products for the fast food market.
