  • Patent number: 4973485
    Abstract: Aqueous orange stripper essences and orange stripper oils are disclosed which have high ratios of more desirable to less desirable orange flavor compounds. For the stripper essences, this ratio is from about 10:1 to about 300:1 and is based on the combined amount of ethyl acetate, ethyl butyrate and acetaldehyde, relative to the combined amount of hexanal and alpha-terpineol. For the stripper oils, this ratio is from about 0.5:1 to about 15:1 and is based on the amount of valencene, relative to the combined amount of alpha-pinene, myrcene, octanal, decanal and linalool.

  • Patent number: 4938985
    Abstract: Commercially processed orange juice products, including frozen orange juice concentrates, which are closer to hand-squeezed orange juice in character are disclosed. At single-strength, these products have a viscosity of about 7 centipoise or less (at 8.degree. C.) and a titratable oil content of about 0.015% or less. These products are further characterized by an orange aroma and flavor component which has a higher ratio of certain desirable "fresh" and "orangey" compounds, relative to certain less desirable orange compounds, when compared to current commercial orange juice products prepared from orange juice concentrate.

  • Patent number: 3994771
    Abstract: A wet-laid composite, soft, bulky and absorbent paper structure is prepared from two or more layers of furnish which are preferably comprised of different fiber types. The layers are preferably formed from the deposition of separate streams of dilute fiber slurries, the fibers typically being relatively long softwood and relatively short hardwood fibers as used in tissue papermaking, upon one or more endless foraminous screens. The layers are subsequently combined to form a unitary web, and the layered, unitary web is dewatered by the application of fluid forces. The moist, layered web is thereafter transferred to an open mesh drying/imprinting fabric. The application of a fluid force to the web creates patterned discrete areas of fibers numbering from about 100 to about 3600 per square inch of projected surface area on the side of the web which contacts the drying/imprinting fabric.
