Abstract: A method of making a snack food in the form of snack food chips, the method comprising the steps of: a. providing at least one pre-processed vegetable material, the pre-processed vegetable material including at least one bioactive component which comprises a polyphenol or a glucosinolate or a mixture of any two or more thereof, wherein the at least one pre-processed vegetable material is in a freeze-dried form, in an individually quick frozen (IQF) form, in a defrosted, chilled or fresh comminuted form and/or in a defrosted, chilled or fresh pulp form; b. incorporating the at least one pre-processed vegetable material into a dough, wherein the dough is a potato-based dough, and wherein the dough forms individual dough sheet portions, and the snack food is in the form of snack food chips; c.

Abstract: A method of de-oiling potato slices, which have been coated in oil, the steps of the method including providing a plurality of potato slices that were pre-treated in oil; and randomly feeding the potato slices onto an elongate longitudinal conveyor which is permeable to oil, water and air. Further, the method includes spraying water downwardly and upwardly onto the plurality of potato slices on the conveyor to displace and lift surface oil from the potato slices. Then, directing air blades to blow a mixture of oil and water from the potato slices as these move along the conveyor.

Abstract: An apparatus for de-oiling potato slices, the apparatus comprising an elongate longitudinal conveyor having an upstream end and a downstream end, the conveyor being permeable to oil, water and air and being adapted to convey potato slices on the conveyor, a water spray station located towards the upstream end and a plurality of air-blower stations located in succession downstream of the water spray station, the water spray station comprising upper and lower water spray units adapted to spray water downwardly and upwardly, respectively, towards the conveyor, and each air-blower station comprising upper and lower air knife units adapted to direct an air blade downwardly and upwardly, respectively, towards the conveyor.

Abstract: A potato chip comprising a cooked potato slice and from 5 to 20 wt % oil based on the weight of the potato chip, wherein the oil comprises a first oil portion within the cooked potato slice and a second oil portion on the surface of the cooked potato slice, the second oil portion comprising no more than 0.2 wt % of the weight of the potato chip.

Abstract: An apparatus for lipophilically conditioning potato slices, the apparatus with an elongate tank for containing a reservoir of oil, the tank having an upstream end and a downstream end, an elongate longitudinal conveyor disposed in the tank, the conveyor being adapted to pass products through the reservoir of oil from the upstream end to the downstream end, the conveyor defining therealong a plurality of compartments for containing respective groups of products during passage from the upstream end to the downstream end, and at least one oil jet located on the tank for causing turbulent flow in the reservoir of oil.
