  • Patent number: 7771793
    Abstract: Polymers, and particularly conventional commodity bulk polymers, are modified to have a surface activity of interest using a surface modifying polymer that includes a moiety that favors migration to the surface of the bulk polymer together with a moiety provides the activity of interest (e.g., biocidal, wettability modifying (hydrophobic or hydrophilic), resistance to radiant energy, providing a functional group for functionalizing the surface, etc.). The surface modifying polymer is combined with the bulk polymer, and, due to the presence of the moiety that favors migration, concentrates primarily on the surface of the bulk polymer such that the moiety that provides the activity of interest is located primarily on the surface of the bulk polymeric article which is produced. Advantageously, only a minimal amount (such as, e.g., about 2 weight %) of polymeric surface modifier is needed. Being able to achieve desired properties (such as biocidal activity, wettability modification, etc.

  • Patent number: 7771761
    Abstract: A calcium lactate crystal inhibitor is added to the typical cheese-making recipe to inhibit the growth of calcium lactate crystals as the cheese ages. The calcium lactate crystal inhibitor is preferably a sodium salt of an organic acid, and is preferably added with sodium chloride or shortly after sodium chloride as part of the salting step. The calcium lactate crystal inhibitor can be identified in a solubility model as being effective in preventing calcium lactate crystal formation by having no or essentially no visually observable crystals and a minimal reduction (less than 5.0%, and more preferably less than 1.0%) in the calcium and lactate content of a calcium L-lactate pentahydrate solubility solution after 14 days of storage at 7° C. The amount of calcium lactate crystal inhibitor salt is within the range of greater than zero to 10% of the weight of the curd, to result in a cheese having 0.26 to 2.8% calcium lactate crystal inhibitor in a cheddar cheese.
