  • Patent number: 10645954
    Abstract: A method of producing a beverage base or a component for a beverage or a food, providing Greek yogurt acid whey which has been obtained by separating the whey from Greek yogurt during a manufacturing process for the Greek yogurt; removing from the acid whey particulate material having a particle size of greater than 10 ?m; filtering the whey, directly or indirectly thus obtained to remove from the whey any bacteria and germinated bacterial spores therein having a molecular mass of at least 10,000 Daltons, the filtering being through a filter having a pore size of no greater than 1 ?m; and filtering the whey, directly or indirectly thus obtained to remove from the whey any enzymes therein having a molecular mass of at least 1,000 Daltons, the filtering being through a filter having a pore size of no greater than 0.1 ?m.
    Type: Grant
    Filed: November 3, 2016
    Date of Patent: May 12, 2020
    Assignee: PepsiCo, Inc.

  • Patent number: 8697163
    Abstract: A method for reducing sorbic acid precipitation during manufacture and storage of stable preserved syrup. A microemulsion of a sorbic acid compound, a non-aqueous solvent, and a surfactant is made in water. Syrup ingredients are added to a bulk quantity of liquid, and the microemulsion is added to the liquid.

  • Patent number: 8691309
    Abstract: A method for reducing sorbic acid precipitation during manufacture and storage of stable preserved syrup. A sorbic acid compound is dissolved in an oil-based ingredient of the syrup. Syrup ingredients are added to a bulk quantity of liquid, and a sorbic acid compound-containing oil-based ingredient is added to the liquid.

  • Patent number: 7700327
    Abstract: A method has been discovered to produce a resistant starch product that retains the same cooking quality as found in untreated rice starch or flour, but has a higher percentage of starch resistant to ?-amylase digestion. This method uses a debranching enzyme, e.g., pullulanase, to digest the starch, but does not require pre-treating the starch source prior to enzymatic treatment. This method produced resistant starch from low amylose starches, rice starch (24%) and rice flour (20%). Surprisingly the resistant starch product formed by this method retained the pasting characteristics of the untreated flour or starch, and was heat stable. This method may also be used to produce resistant starch from other botanical sources, e.g., corn, wheat, potato, oat, barley, tapioca, sago, and arrowroot. Resistant starch produced by this method has a variety of uses in food products.
