  • Soup concentrates
    Patent number: 4140809
    Abstract: A variety of soup concentrates, each containing meat or vegetable particulates, or both, is prepared with a water soluble solids content sufficient to prevent the soup concentrate from solidifying at home freezer temperatures (0.degree. F. to 15.degree. F.) and thereby effects a readily spoonable, semi-rigid consistency which lends itself to single serving dispensing and dilution with hot water to form an excellent quality soup.
