  • Patent number: 10143206
    Abstract: An edible composition comprising starch and cellulose ether particles, wherein the cellulose ether particles have a ratio M3.0/M2.0 of not more than 200 micrometers, wherein M3.0 is the number volume mean and M2.0 is the number surface area mean of the cellulose ether particles, and/or wherein the cellulose ether particles have a volume fraction of fibrous particles of no more than 40%, is useful for preparing a batter by mixing the edible composition with water. The batter is contacted with a food to prepare a battered food. The battered foods have a reduced oil and/or fat uptake when fried, as compared to fried non-battered food.

  • Patent number: 8973853
    Abstract: In a process for producing a particulate polysaccharide derivative by dry-grinding a moist polysaccharide derivative, one or more of the properties selected from median diameter, median length, bulk density and dissolution rate is controlled by controlling the temperature of the polysaccharide derivative prior to dry-grinding. Advantageously one or more of the properties selected from median diameter, median length, bulk density and dissolution rate of the particles after dry-grinding is adjusted to a first value by a first temperature of the polysaccharide derivative prior to dry-grinding and is adjusted to a second value by a second temperature.
