  • Patent number: 5236733
    Abstract: Reduced calorie, low moisture fat-containing foods such as potato chips having less waxiness and improved flavor display are disclosed. These benefits are typically obtained by applying to the surface of the potato chip, or other food, fat compositions having certain thixotropic areas that correlate to reduced waxiness impressions. These fat compositions comprise a nondigestible fat component, and optionally a digestible triglyceride fat or oil. The nondigestible fat component comprises a nondigestible oil and certain solid polyol fatty acid polyesters having ester groups consisting essentially of long chain (C.sub.14 or higher) saturated fatty acid radicals that bind such liquid oils and thus control or prevent passive oil loss.

  • Patent number: 5227188
    Abstract: Roasted coffee granules are admixed with roasted coffee non-granules in critical weight ratios. The smaller coffee non-granules include flaked coffee, flaked coffee fines, ground coffee fines, and coffee agglomerates. The larger coffee granules include roast and ground coffee. The coffee granules and coffee non-granules are densified to between 0.41 to 0.56 grams/cc. The compact coffee has the flowability, flavor, aroma and strength of roast and ground coffee. At equal volumes, the compact coffee results in more brewed coffee than conventional roast and ground coffee.

  • Patent number: 4935022
    Abstract: The present invention provides absorbent articles, such as disposable diapers, which utilize a particular type of stiffened cellulose fibers and a particlar type and form of polymeric gelling agent particles to enhance the absorbency characteristics of such articles. In these articles, the gelling agent material, combined in particulate form of a certain size with stiffened cellulose fiber material, is primarily placed in a lower fluid storage layer of the absorbent core of the article. Such a fluid storage lower layer of the absorbent core is placed underneath an upper, generally larger, fluid acquisition/distribution layer which also contains stiffened cellulose fibers and gelling agent particles of a certain size. This lower fluid storage layer is generally positioned toward the front of the absorbent article. Absorbent articles of this type can be fashioned into especially thin, compact, nonbulky diapers.
