  • Patent number: 8017164
    Abstract: A method for peeling fruits and vegetables, particularly those having thin skins, such as tomatoes includes immersing the fruit or vegetable in a boiling solution comprising carbamide and one of carborane and hydrogen chloride to loosen a peel thereof. In a particular embodiment, the carborane comprises trifluoromethanesulfonic acid. The fruit or vegetable is removed from the solution after a predetermined time period. The fruit or vegetable is cooled, and the loosened peel is removed from the fruit or vegetable.

  • Publication number: 20100151094
    Abstract: Methods, apparatuses, and systems for removing the peels/skins from agricultural produce, such as fruits and vegetables, are disclosed. The peel and/or the connection between the peel and the flesh of the produce can be at least partially destroyed by a caustic fluid and/or steam. Once the peel has been sufficiently loosened from the flesh, forced air may be applied to the surface of the produce to remove the loosened peel and any residual caustic fluid. Using air to remove the loosened peel instead of the conventional use of water significantly reduces the freshwater requirements and substantially reduces the quantity of wastewater discharge with very low concentration of contaminants. The peels, caustic fluid, and water can be collected and separated, after which the peels can be neutralized and fed to livestock, used as fertilizer, or used for pectin production, and the caustic fluid and residual water can recycled into the system.

  • Patent number: 6805902
    Abstract: Micro-optical elements such as lenses and wave-guides are manufactured by printing a hardenable optical fluid using digitally driven ink-jet technology. An array of micro-optical elements are precisely positioned in an electroformed substrate having a surface containing structural openings which serve as molds for micro-droplets of optical fluids deposited from an ink-jet printhead. The structural openings have a stepped down edge, a shelf-like support surface below the edge and a centered aperture in the substrate. The micro-optical element formed is controlled by the shape of the edge in the surface of the substrate and the radius by the volume of micro-droplets deposited into the structural opening. The structural openings can be circular, or any desired shape which is easily and precisely formed in an electroformed substrate.

  • Patent number: 5989615
    Abstract: The removal of albedo in the preparation of a citrus fruit for consumption, in which a known aqueous solution of pectinase enzyme is used for its known albedo-removal function, but in the present circumstances a vacuum is used to primarily draw the pectinase enzyme to the interface of the albedo and the citrus fruit and only nominally to the interface of the albedo and the peel of the citrus fruit, so that removal of the peel carries with it the albedo and uncovers the citrus fruit in a desirable albedo-free condition.

  • Patent number: 5786014
    Abstract: An improved higher capacity caustic peeler of fruits such as tomatoes. The peeler subjects the tomatoes to a caustic applicator with shallower buckets with apertures in the buckets and a higher number of caustic dispensing jets, and then provides peeling using a flexible cable cage, which tumbles the tomatoes. A pinch roller is used to remove the remainder of the peels (or skins).

  • Patent number: 5200217
    Abstract: A process for peeling fresh citrus fruit to provide peeled whole fruit, with ease of peeling and with limited amounts of adhering albedo. The fresh citrus fruit are initially chilled to a temperature well below room temperature, preferably less than about 10 degrees C. The chilled fruit are then scored so as to penetrate the albedo layer, but not the underlying juice sections, and the scored fruit are then immersed in an aqueous solution of a pectinase enzyme at an initial temperature of about 35 degrees C. The enzyme solution is then infused into the fruit, and after holding the infusion-treated fruit in the solution for a prescribed time period, without application of additional heat, the peel can be readily removed from the whole fruit.

  • Patent number: 5196222
    Abstract: An apparatus peels fruit, in particular citrus fruit, by washing and sterilizing the fruit in a sterilizing bath. The washed and sterilized fruit is delivered to a perforator which makes a plurality of perforations through the outer surface of the peel of the fruit over its entire surface. The perforated fruit is then delivered to a conveyor which loads and orients the fruit so that it is spinning on the stem axis with the equator of the spinning fruit exposed to a plurality of slitting knives. The knives slit an equatorial cut through the outer surface of the peel. The slit and perforated fruit is then delivered to a carousel of canisters. Each canister is filled with fruit and an aqueous solution of a commercial pectinase. The solution is vacuum infused into the fruit so that the albedo attaching the peel to the fruit substantially disintegrates over a predetermined time period.

  • Patent number: 5000967
    Abstract: An improved process for preparing individual fruit sections from fresh citrus fruit, with improved ease of peeling and sectioning and with reduced amounts of adhering albedo. The fresh citrus fruit are initially scored so as to penetrate the albedo layer, but not the underlying juice sections, and the scored fruit is then immersed in an aqueous solution of a pectinase enzyme. A series of positive pressure pulses is applied to the immersed fruit, to infuse the enzyme solution into the albedo and, after storing the infusion-treated fruit for a prescribed time period, the peel and other membrane material can be readily removed from the fruit and the individual fruit segments readily separated from each other. Infusing the pectinase enzyme solution under pressure, rather than vacuum, and maintaining the solution at approximately room temperature, rather than an elevated temperature, significantly improves the ease of peeling and sectioning and reduces the amount of adhering albedo.

  • Patent number: 3950552
    Abstract: Apple sauce is produced in a continuous process stream without hand trimming by dicing the untrimmed, sometimes uncored fruit, electronically sorting the dices to reject blemished dices, and cooking and conventionally finishing the accepted blemish free dices. The reject dices are reduced to blemished and unblemished tissue by being either (1) rediced into smaller pieces and resorted, (2) sliced to further subdivide them while in an auxiliary processing path and returned to the process stream for resorting, (3) sliced to further subdivide them and resorted while in an auxiliary processing path whereafter surviving unblemished tissue is returned to the process stream, or (4) blemished dices from the original sorting or from the resorting of step 3 are routed to a separate cooker and fine screen finisher to produce a nearly blemish free fine sauce which in turn is blended with the conventionally finished sauce produced from the accepted dices. The fruit may be lye peeled prior to dicing.
