  • Patent number: 5281432
    Abstract: The present invention provides foods containing soluble high amylose starch selected from: (i) spray-dried, non-granular starch, characterized in that the starch is substantially non-crystalline, substantially nonretrograded, and fully predispersed; (ii) spray-dried, uniformly gelatinized starch in the form of granular indented spheres, with at least a majority of the granules being whole and unbroken, the starch granules being in the form of loosely-bound agglomerates or individual granules; (iii) enzymatically debranched gelatinized starch, comprising at least 40% amylose; and (iv) mixtures thereof.The foods prepared with soluble high amylose starch are characterized by one or more of the following beneficial properties: stronger gels, improved appearance, improved adhesion, air-, oil- and/or water-impermeable surfaces; and improved textures.

  • Patent number: 4695475
    Abstract: An imitation cheese product, which is functionally equivalent to a caseinate-based imitation cheese product, contains pregelatinized modified high amylose starches, preferably converted and/or derivatized, as a partial or total replacement for the caseinate present in the cheese. Suitable converted starches include fluidity starches prepared by acid- or enzyme-conversion, oxidized starch prepared by treatment with less than 5% active chlorine, and dextrins having a calcium chloride water fluidity of less than about 50. Suitable derivatives are prepared by treatment with up to 25% propylene oxide, 5% succinic anhydride, and 10% octenylsuccinic anhydride or with a sufficient amount of acetic anhydride or sodium or potassium ortho or tripolyphosphate to provide a maximum of 6% bound acetyl or 0.8% bound phosphate. Mixtures of modified or unmodified high amylose starches with up to 80% by weight of other starches (0-40% amylose) are also suitable.

  • Patent number: 4499116
    Abstract: An imitation cheese product, which is functionally equivalent to a caseinate-based imitation cheese product, contains selected edible modified starches as replacements for up to 80% by weight of the caseinate present in the cheese product. Suitable starches include pregelatinized converted starches having a water fluidity (WF) of about 5-90 and an amylose content of at least about 15% to below 40% and selected derivatives and/or crosslinked products thereof. Suitable converted starches include fluidity starches prepared by acid- or enzyme-conversion or oxidized starches prepared by treatment with up to about 2% active chlorine. The starches may be pregelatinized by drum-drying and jet-cooking, or jet-cooking and spray drying.

  • Patent number: 4460617
    Abstract: A dry, protein-free coffee whitener comprises a dried emulsion concentrate comprising an edible fat having an average particle size of about 1-3 microns in diameter. The fat is stabilized with a degraded and chemically modified starch derivative having a flow viscosity of at least 15 seconds and a lipophilic character in an amount sufficient to provide said concentrate with a starch derivative to fat ratio in the range of 0.05-0.3 to 1. A method of preparing the stable, dry, protein-free coffee whitener comprises forming a liquid emulsion concentrate comprising water and the stabilized edible fat and drying the liquid emulsion concentrate.
