  • Treating food crops (e.g., perishables such as vegetables, fruits, or grains) after removal (pickled/harvested) with the compounds, products and compositions of the present invention imparts antimicrobial protection to the outer surface of the food crop. It is believed that such protection occurs without diffusing, migrating or leaching the antimicrobial agent from the bonded antimicrobial coating of the food item, and provides prolonged, safe and non-toxic antimicrobial protection.
  • the method involves treating fruits and vegetables in the rinse cycle, during or after the normal cleaning/water spraying or during or after blanching. Thorough cleaning of fruits and vegetables at the processing plant is preferred for initially removing microorganisms.
  • machines are used initially to remove soil, chemicals used in growing, spoilage bacteria, and other foreign materials. These machines also use high velocity water sprays to clean the products. After the cleaning, raw foods or other crop materials are prepared for further processing such blanching (i.e., the food is immersed in water at 190 to 210 degrees F. or exposed to steam).
  • Microorganisms are controlled by the production plant up until the fruit or vegetable is removed. But once it is removed, organisms such as yeast, mold, and bacteria, begin to multiply, causing the food to loose flavor and change in color and texture. To keep the food from spoiling, a number of methods have been employed, such as refrigerators, to slow down the microorganisms and delay deterioration. Unfortunately, such known methods will preserve raw foods for few weeks at the most.
  • the compounds, products and compositions of the present invention can preserve these items for extended periods. For instance, the compositions, products, or compounds may be added to an existing water line feeding the sprayers for the foods, where such sprayers are used. Otherwise, a simple dipping process may be used, where the dipping requires only a few seconds to impart antimicrobial protection. Low concentrations of 0.1 to 1% aqueous solution (0.1 to 1% by volume) of the compositions provide satisfactory results. In addition, it is believed that the presently described method can also control pathogens on poultry carcasses and in other susceptible meat and fish.
  • the present compounds, products and compositions can be used to treat these articles to prevent microbial growth and contamination by coating an effective amount of the products and compounds of the invention thereon.
  • the articles employed can be coated by allowing for 1 to 2 minutes submersion (e.g., by dipping), and thereafter, the treated surface is allowed to dry at room temperature. The article is then rinsed of any excess antimicrobial agent.
  • Thorough cleaning and sterilization is a preferred step in removing the microorganisms on the surface of the article prior to "coating" the said articles.
  • concentrations of 10% or less by weight of the compounds, products and compositions of the invention in water are used for long lasting protection.
  • Treating surgical gloves with the compounds, products and compositions of the present invention before or during a surgical procedure can kill microorganisms on contact . It is believed that the treated gloves do not diffuse or leach the antimicrobial agent from the glove surface and provide prolonged antimicrobial activity with safe and non-toxic antimicrobial protection.
  • Surgical gloves are treated, preferably, by submerging in the solution of Example I, diluted to 1% W/V for at least 30 seconds. This method will permit doctors to use and, if necessary, re-use the same gloves (even without removing them) without undue fear of contamination.
  • Treating polymers and other materials such as concrete by incorporation into the bulk material protects from deterioration, odor build-up and potentially harmful contamination of the surface. Incorporation of a sun protection into polymers and/or application of sun protection to the surface extends the life of the product and reduces damage to products and skin.

  • silane in the following examples is Dow Coming 5772 or a silane of similar composition as Dow Coming 5772. Both are collectively referred to as silane concentrate.
  • a solution or mixture is considered stable if an aqueous solution can be produced and remain without precipitation of the silane for a longer time than would be expected for the non- stabilized silane. If the silane itself is insoluble in water then the formation of an aqueous solution is a benefit within the scope of the invention.
  • Example 2 The following table lists examples of mixtures and their stability. The entries are in weight percent of total mixture. A solution 50 weight percent silane concentrate and 50 weight percent propylene carbonate was prepared and then diluted with water according to the table.
  • reaction product of the previous example was dissolved in water, to prepare stable silane water mixtures.
  • Sample 2 of the previous example was after 35 days diluted further with 4 parts water and applied to white textile fabric. After drying, the fabric was hand washed in running water 20 times. The sample was again allowed to dry and then tested according to Dow Coming Corporate Test Method 0923. In this test method the fabric sample is placed together with an inoculated nutrient solution into an erlenmeyer flask. For this experiment the procedure was slightly modified, the mixture was shaken for 24 hours instead of 1 hour and the organism used was aspergillus niger instead of klebsiella pneumoniae. Percent reduction is determined by counting the organisms at zero time and at the end of the experiment. The percent reduction found in this example was 99.98%.
