  • Patent number: 11930970
    Abstract: Exemplary power systems for dynamically controlling a dispenser drive motor for dispensing soap, sanitizing or lotion. An exemplary soap, sanitizing or lotion dispenser includes a housing, a receptacle for receiving a container for holding a soap, sanitizing or lotion, a container of soap, sanitizing or lotion and a pump secured to the container. The exemplary soap, sanitizing or lotion dispenser includes a power source, a motor and an actuator that couples the motor to the pump. In addition, the exemplary soap, sanitizing or lotion dispenser includes pulse width modulation circuitry in circuit communication with the power source and the motor. Movement of the actuator one actuation cycle dispenses a dose of soap, sanitizing or lotion. The pulse width modulation circuitry provides a plurality of voltage pulses to the motor to move the actuator one actuation cycle.

  • Patent number: 7955439
    Abstract: A process for producing an enzyme-resistant starch uses an aqueous feed composition that comprises (i) starch that contains at least about 50% by weight amylose, (ii) water, and (iii) alcohol. The concentration of starch in the feed composition is between about 5% and about 50% by weight, and the pH of the feed composition is between about 3.5 and about 6.5. In a first heating step, the feed composition is heated to a temperature between about 130-170° C. for about 0.1-3.0 hours. The feed composition is cooled to a temperature between about 4-70° C. for about 0.1-6.0 hours. In a second heating step, the feed composition is heated to a temperature between about 110-150° C. for about 0.1-10.0 hours. The starch is separated from the majority of the water and alcohol and is dried.

  • Publication number: 20090011082
    Abstract: A process for producing a starch comprises treating a feed starch that comprises amylopectin with glucanotransferase to produce a chain-extended starch, and treating the chain-extended starch with a debranching enzyme to produce a starch product that comprises amylose fragments. In certain embodiments, the process further comprises, crystallizing at least part of the starch product, heating the starch product in the presence of moisture, treating the starch product with alpha-amylase, and washing the starch product to remove at least some non-crystallized starch, wherein the degree of polymerization of the starch product is increased by increasing the amylose content of the feed starch or is decreased by decreasing the amylose content of the feed starch. The product of this process can have a relatively high total dietary fiber content, a relatively high heat resistance, or both.

  • Patent number: 6113976
    Abstract: A food formulation having a reduced level of fat and/or oil is provided. The food formulation is a mixture of a foodstuff and a fragmented, amylopectin starch hydrolysate as a replacement for at least a substantial portion of the fat and/or oil of said food formulation. The fragmented starch hydrolysate is capable of forming an aqueous dispersion at about 20% hydrolysate solids exhibiting a yield stress of from about 100 to about 1,500 pascals. Also provided is a method of formulating a food containing a fat and/or oil ingredient comprising replacing at least a portion of said fat and/or oil ingredient with the fragmented, amylopectin starch hydrolysate. Examples of food formulations include those for margarine, salad dressings (pourable and spoonable), frostings, and frozen novelties.

  • Patent number: 5436019
    Abstract: A method of preparing reduced fat foods is provided which employs a fragmented, .alpha.-amylase hydrolyzed amylose precipitate. Amylose is precipitated and hydrolyzed with .alpha.-amylase and then fragmented to form an aqueous dispersion that is useful in replacing fat in a variety of food formulations. The amylose can be derived from a native starch which contains amylose, e.g. common corn starch and high amylose corn starch, by gelatinizing the starch followed by precipitation of the amylose.

  • Patent number: 5409726
    Abstract: A method of preparing reduced fat foods is provided which employs a fragmented starch hydrolysate. A granular starch hydrolysate or a debranched amylopectin starch precipitate is fragmented to form an aqueous dispersion that is useful in replacing fat in a variety of food formulations. A wet blend of the fragmented starch hydrolysate and a hydrophilic agent is dried. The dry blend can be easily redispersed in water to form a particle gel useful in replacing fat and/or oil in a food formulation.

  • Patent number: 5387426
    Abstract: A method of preparing reduced fat foods is provided which employs a retrograded, hydrolyzed, heat-treated, and fragmented, amylose starch. Amylose is precipitated and hydrolyzed with acid or .alpha.-amylase, solubles are removed by a heat treatment and the resulting solids are then fragmented to form an aqueous dispersion that is useful in replacing fat in a variety of food formulations. The amylose can be derived from a native starch which contains amylose, e.g. common corn starch and high amylose corn starch, by gelatinizing the starch followed by precipitation of the amylose.

  • Patent number: 5378491
    Abstract: A method or preparing reduced fat foods is provided which employs a fragmented, granular amylose starch having a melting onset temperature (as measured by differential scanning calorimetry) of greater than about 70.degree. C. when measured at 20% starch hydrolysate solids. The fragmented, granular amylose starch hydrolysate is prepared by hydrolyzing a granular amylose starch in a strongly acidic aqueous slurry at a temperature greater than 70.degree. C. or by hydrolysis at a lower temperature followed by heating a slurry, after neutralization, to raise the melting onset temperature. Also provided are food formulations in which the fragmented, granular amylose starch hydrolysate is used to replace fat and aqueous dispersions of the fragmented, granular amylose starch hydrolysate which are useful therein.

  • Patent number: 5374442
    Abstract: A method of preparing reduced fat foods is provided which employs a recrystallized and fragmented amylose precipitate. A starch having both amylose and amylopectin is gelatinized to allow preparation of pure amylose as a permeate of membrane foltration. The amylose is precipitated, recrystallized and then fragmented to form an aqueous dispersion that is useful in replacing fat in a variety of food formulations. The amylose precipitate can be derived from a starch which contains amylose, e.g. common corn starch, by gelatinizing the starch followed by precipitation of the amylose separation.
