Abstract: Methods of preserving fresh fruit with fresh fruit preservatives which extend the shelf life of fresh fruit particularly fresh cut fruit, are provided. The fresh fruit preservative preserves the texture, flavor, appearance, crispness, and color of the fresh fruit, particularly the exposed skin of the fresh fruit. The method includes the following steps: providing a solution of fruit preservative comprising: water, calcium ions; and ascorbate ions, wherein the calcium ion and ascorbate ions are present in a ion ratio of preferably from about 1.5:1 to about 2.5:1; and, applying said fruit preservative to the fruit. Preferably the fruit is then stored at a temperature which will not freeze the fruit; temperatures of -6.degree. C. have been found not to freeze the apples. Preferably the fruit is stored at temperatures of between about -7.degree. C. to room temperature, about 20.degree. C., more preferably about -2.degree. to about 7.degree. C., most preferably from about 2.degree. C. to about 5.degree. C.

Abstract: Improved, stable, germicidal, aqueous teat-dip compositions are disclosed, which include a film-forming agent selected from the group consisting of hydroxyethylcellulose, methyl hydroxypropylcellulose, and ethylhydroxyethylcellulose, a germicidal agent, preferably iodine complexed with a nonionic surfactant, and water to provide a solution having a viscosity of about 50 to 1000 cp. The liquid, aqueous compositions, when applied to the teats of agricultural animals, dry to form a continuous barrier film, which functions both as an effective anti-microbial agent and as an effective barrier at the mouth of the milk channel to prevent or reduce the incidence of mastitis.

Abstract: A process for the surface fluorination of a carbon containing synthetic or natural polymer capable of forming a carbon-fluoride bond on fluorination, in a glow discharge reactor, utilizing inorganic fluorides as the fluorination agent.

Abstract: A process and apparatus for dewatering an ethanol-water solution is disclosed wherein a carrier gas is used to vaporize the solution and transport the vapors to a sorbent where water is sorbed in preference to ethanol. The invention is particularly suited for small-scale production of fuel-grade ethanol for blending with gasoline.
