  • Method for predicting intrinsic properties of a mixture
    Patent number: 6159255
    Abstract: A method for predicting an intrinsic property of a mixture comprising at least two components by: (a) selecting components and an equation; wherein the equation relates amounts of the components to the intrinsic property of the mixture; (b) selecting experimental compositions, each of which comprises at least one of the components; (c) measuring a correlational property of each of the experimental compositions by a correlational technique; and (d) determining a set of coefficients for the equation; wherein in the equation, each of the coefficients is multiplied by a concentration of a component or a product of concentrations of two or more components.

  • Method of treating a consumable product and packaging for consumable products to indicate the presence of contamination
    Patent number: 4847066
    Abstract: A method is described for treating consumable products, such as foods, drugs or dietary supplements, for example drugs enclosed in capsules, to detect contamination. A colorimetric indicator, which can react with a contaminating substance such as cyanide, is incorporated into the consumable product or the packaging for the product. When the indicator comes in contact with the contaminating substance, a readily detectable color signal is produced.
