  • Patent number: 4976978
    Abstract: A method for preparing a food product is disclosed wherein formed food is prepared with a particulate coating. Here a plastic, deformable food material is made from rolling a food in the presence of particulate coating material in a revolving drum to thereby reshape the food particle into a roundish, coated body. The roundish body is preferably spherical, annular or roundish cylindrical. The food material is, for instance, mashed potato, minced fish or dough and preferably an aerated, frozen confection.

  • Patent number: 4882187
    Abstract: Process for preparing an edible spread of fat content lower than butter or margarine including the steps of forming an admixture of plastic dispersion (A) having a continuous fat phase and a discontinuous aqueous phase, which aqueous phase has a pH above 4.7 and contains protein selected from the group consisting of milk protein, soy protein and mixtures thereof, and an aqueous composition (B) having a pH at or below 4.7 and containing hydrocolloid, the aqueous composition (B) being substantially free of milk protein and soy protein, and subjecting the admixture of (A) and (B) to a working treatment at a temperature at which (A) remains plastic. The spread so obtained has a continuous fat phase and two distinct aqueous phases, one having the characteristics of the aqueous phase of (A), the other the characteristics of (B).
