A method of processing tobacco fines into a non-continuous tobacco material includes providing a pre-sized tobacco stem material that has a Dp90 particle size of less than 2.5 mm and a Dp50 particle size of between 0.7 mm and 1.5 mm, combining the pre-sized tobacco stem material with tobacco fines to provide a tobacco initial material, wherein the tobacco initial material includes between 40% and 60% pre-sized tobacco stem material (by mass). The method can include processing the initial material by setting the initial material to a predefined increased moisture content, subjecting the initial material to an increase in temperature and subjecting the initial material an increased pressure in order to bind the tobacco fines to the tobacco stem material, and conveying the initial material through a conveyor. The method can include feeding the processed tobacco material through a shearing gap such that the processed tobacco material is defibrated by expansion.

A process is provided for the treatment of tobacco. The process comprises securing the tobacco within a moisture-retaining material and exposing the tobacco material to an ambient processing temperature of above 55° C., with the tobacco having a packing density of at least 200 kg/m.sup.3 on a dry matter weight base at the start of the process and a moisture content of between about 10% and 23%. The treated tobacco may have desirable organoleptic properties.

The present invention provides a method of treating tobacco material comprising intermittently contacting a tobacco starting material with a heated surface to produce a dried treated tobacco material. Also provided is an apparatus for treating tobacco material. The invention also provides treated tobacco material that is seared and dried, as well as products comprising the same.

A helmet locking device that allows a rider to securely lock the helmet to a supporting structure, such as a motorcycle. The device includes a mounting bracket configured to conform to and fit around a tubular structure on the motorcycle. The device also includes an anchoring member that is mounted on to the helmet. The mounting bracket and the anchoring member include elements that allow them to be slidably coupled to each other and secured by a locking element thus preventing the removal and theft of the helmet.

A method of modifying the moisture level of (e.g., dehydrating) a tobacco plant or portion thereof, a tobacco-derived material, a tobacco product, or a tobacco additive is provided herein. The methods of dehydration disclosed herein can provide various benefits relative to traditional drying techniques, including providing retention of various beneficial components present in green tobacco (e.g., organoleptic compounds and proteins). Smoking articles and other tobacco products including such dehydrated tobacco materials are also provided.

Provided is a method of producing a cured tobacco material having an enhanced threonine content. The present invention provides a method of producing a cured tobacco material having an enhanced threonine content, wherein the cured tobacco material is produced from a modified tobacco plant which has been modified such that expression or activity of an endogenous threonine aldolase is reduced or from a part of the modified tobacco plant.
