Patent number: 5629090Abstract: A starch hydrolysate composition is particularly suited for use as a sequesterer, i.e., it readily interacts noncovalently with other molecules to form stable inclusion complexes which are useful in a variety of applications. The starch molecules in the composition which act as sequesterers are in the form of single helical inclusion complexes with starch molecules having a D.P. of about 10 to 200 and a weight-average D.P. of about 10 to 50 as the host molecule holding one or more guest molecules within their internal cavities. These hydrolysates are prepared by first converting amylopectin molecules from the double helix form to the single helix form and then by cleaving chain segments from the molecules.Type: GrantFiled: June 7, 1995Date of Patent: May 13, 1997Inventor: James E. Eastman

Patent number: 4256509Abstract: A method of modifying the viscosity characteristics of a starchy flour by physical treatment, including heating in alcohol in a confined zone. The resulting starchy flour exhibits thin-thick viscosity characteristics when heated, and provides added viscosity in acid systems without breaking down. It has particular application to baby food recipes to impart desired texture and mouthfeel. Oat flour is the presently preferred starchy flour to be treated for use in baby foods.In one embodiment, a starchy flour is slurried in an aqueous organic liquid, preferably ethanol, and is then subjected to heat and pressure for a predetermined time to modify the physical properties of the flour. The specific combination of pressure, temperature, and heating time determine the properties of the treated flour.Type: GrantFiled: May 14, 1979Date of Patent: March 17, 1981Assignee: A. E. Staley Manufacturing CompanyInventors: John V. Tuschhoff, James E. Eastman, Schanefelt Robert V.

Patent number: 4120982Abstract: A thin-thick, hydroxypropylated, epichlorohydrin crosslinked tapioca-based starch derivative for continuous process pressure cooking of acid food systems. The degree of crosslinking of this starch derivative is carefully controlled so that it is initially low in viscosity and develops full viscosity only under high pressure and temperatures. These characteristics make this starch derivative ideally suited for use in recently developed acid medium, food canning processes in which initial rapid heat penetration without degrading the starch derivative is necessary for the heat sterilization of the canned foods. For the new continuous retort processing, the usual time allowed for the complete retorting cycle is less than twenty minutes, and this must include heat sterilization. As the retort medium using the starch derivative of the invention reaches the heat sterilization temperature, it then increases in viscosity to a range which retains the canned food product in a desirable suspension.Type: GrantFiled: September 22, 1975Date of Patent: October 17, 1978Assignee: A. E. Staley Manufacturing CompanyInventors: James E. Eastman, Frank DEL Valle

Patent number: 4038482Abstract: Root and root-type starch derivatives having controlled acetyl substitution levels which provide an initial high paste viscosity to facilitate uniform filling operations when used as a food canning medium, and which break down to a thinner viscosity upon heating to facilitate heat penetration into the canned food mass for sterilization of the canned food product and to provide a more acceptable watery or soup-like consistency to the food product. The thinning phenomenon is accomplished without the requirement of adding any separate hydrolyzing or thinning agent such as an acid or enzyme. It is presently thought that these acetylated starch derivatives are capable of self-hydrolysis under the retort conditions of pH and temperature, and that this auto-hydrolytic thinning action during heating of the pasted product is sufficient to thin the starch derivative canning media partially or completely, as desired.Type: GrantFiled: September 29, 1975Date of Patent: July 26, 1977Assignee: A. E. Staley Manufacturing CompanyInventor: James E. Eastman

Patent number: 3966990Abstract: A dough binder for puffable food products comprising an alcohol washed, granular hydroxypropyl waxy-maize based starch derivative obtained by the dry reaction of acid hydrolyzed waxy maize starch which has also been treated with anhydrous disodium phosphate and propylene oxide to a hydroxypropyl degree of substitution of 0.3 to 0.5. The granular, crude starch derivative is cold water swelling, and is alcohol washed and dried to 3-5 percent moisture.Doughs made using the subject granular, ungelatinized starch derivative as a dough binder are more formable and workable, having the consistency of modeling clay. It is non-sticking, but readily cold-formable when used at about 30-70 percent of our starch derivative. 0-10 percent shortening, 0-30 percent other food materials, and 10-40 percent water. The dough mixture is then cold formed into the desired shapes and sizes, and may be baked or cooked at elevated temperatures (300.degree.-475.degree.F.Type: GrantFiled: February 11, 1974Date of Patent: June 29, 1976Assignee: A.

Patent number: 3959514Abstract: Root and root-type starch derivatives having controlled acetyl substitution levels which provide an initial high paste viscosity to facilitate uniform filling operations when used as a food canning medium, and which break down to a thinner viscosity upon heating to facilitate heat penetration into the canned food mass for sterilization of the canned food product and to provide a more acceptable watery or soup-like consistency to the food product.Blends of several root and root-type starch derivatives make possible a predictable final viscosity level which is not completely "water-thin." The selection of acetylating agent also affects the final viscosity level of the starch canning medium. It has been observed that a starch derivative substitute using vinyl acetate provides a slightly higher final viscosity under the same retorting conditions when compared to a starch derivative which has been substituted using acetic anhydride.Type: GrantFiled: May 28, 1974Date of Patent: May 25, 1976Assignee: A. E. Staley Manufacturing CompanyInventor: James E. Eastman

Patent number: 3951947Abstract: A thin-thick, hydroxypropylated, crosslinked root-type starch derivative for continuous process pressure cooking, which remains stable over a wide pH range (3-7), and maybe used in both neutral and acid food systems. Suitable base starches include waxy maize, waxy milo, waxy sorghum, and any amylopectin-rich starch which is low in amylose contents.These hydroxypropylated starch derivatives are non-jelling, heat stable, freeze-thaw, and are crossed linked to a level at which their aqueous suspensions are initially low in viscosity and then developed full viscosity upon heating in sealed containers, thereby permitting initial rapid heat penetration necessary for the heat sterilizations of canned foods processed in high temperature-short time sterilization (HTST) food canning processes, in which the complete retorting cycle is less than 20 minutes.Type: GrantFiled: September 17, 1974Date of Patent: April 20, 1976Assignee: A. E. Staley Manufacturing CompanyInventors: Robert V. Schanefelt, James E. Eastman, Michael F. Campbell
