Description

BACKGROUND

Hookahs have been used to smoke tobacco for at least four centuries. Hookah terminology varies upon region. Hookahs can be referred to as a waterpipe, huqqa or huqqo, argilah or argileh, lula or lulava, shisha or sheesha, narguile or nargile, qalyan, mada'a, chillim, jajeer, guduguda, hitboo, marra pipe, or cachimba. Hookahs come in various colors, materials, shapes, and sizes.
The basic hookah apparatus includes a head or bowl that holds the charcoal and tobacco during the smoking session, a body, a water bowl, a hose, and a mouth piece. A hookah apparatus also can include a windscreen that covers the bowl area, a purge valve, a plate or ashtray to catch ashes falling from the coals, grommets for sealing joints between the connected parts of the hookah apparatus, a diffuser, and consumable items, such as coal or charcoal, flavored hookah tobacco or mu'assel, and non-tabacco based mu'assel.
Traditionally, tabacco has been the smoking material of choice for hookahs. The types of tabacco used, as well as casings and flavors added, can vary. Generally, hookah tobacco is highly flavored. When tobacco is smoked in a hookah, however, the smoker is subjected to a number of potentially unhealthy components that are inherent to tobacco-based products.
The consumption of tobacco-based products, such as cigarettes, has been decreasing in recent years due to the increased awareness of the health risks associated with tobacco use. Accordingly, alternatives to tobacco are of interest to consumers. As an example, electronic cigarettes have been shown to be a viable alternative for nicotine delivery, as well as a way for tobacco consumers to quit their tobacco smoking habit.
Non-tobacco based smoking materials also are available for hookahs including, but not limited to, fruit-based shisha, herbal shisha, tea-based herbal shisha, nicotine-free herbal molasses, tobacco- and nicotine-free vapor or steam stones, and shisha gels. Fruit-based shisha and shisha gels, however, are very moist and, as a result, are difficult for the hookah smoker to manipulate in the smoking apparatus.

B. Methods of Preparing the Presently Disclosed Tobacco-Free Smoking Gel

In some embodiments, the presently disclosed tobacco-free smoking gel can be prepared as follows:

The first step is the preparation of a syrup to be used to disperse the flavorings and/or nicotine in the proper concentration. The syrup is a mixture of humectant agents (from about 1% to about 99%, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99% humectant agents) and a source of sugar (from about 1% to about 99%, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99% source of sugar). Humectants play a key role in the presently disclosed formulation, since they are used not only to keep the residual humidity in the system, but also because the final dry gel material will benefit from their known capacity to act as plasticizers.

The mixture of the humectant and the source of sugar are stirred for about 5 minutes to about 50 minutes with a mechanical stirrer at from about 100 rpm to about 1,500 rpm speed, depending on the volume that is being prepared. For example, when preparing a volume of about 100 mL of syrup, components are added in the desired concentration and stirred using a low speed rate, but when the volume reaches about 10L, the speed must be increased. In most cases, the mixture is made at room temperature, e.g., between about 10 °C to about 25 °C, including 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, and 25 °C.
The second step comprises the addition of flavors and/or nicotine to the syrup. Once the syrup is ready, the flavor (or aroma) is added to the syrup and stirred at room temperature for about 5 minutes using a mechanical stirrer (speed of about 100 rpm to about 1,500 rpm depending on the volume that is being prepared).
The flavor(s) and syrup concentrations may vary as follows: syrup (about 55% to about 99%, including about 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99% syrup) and flavor(s) (about 1.0% to about 45%, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45% flavor(s)). Different types of flavors can be added to the syrup. In general, these flavors are complex mixtures of flavor chemicals and/or natural ingredients.
The addition of nicotine to the gel may be performed by adding pure nicotine (natural or synthetic), its solutions or salts. As an alternative, extracts of different types of tobacco, such as: Arapiraca, Oriental tobacco (Turkish tobacco), Virginia tobacco (Bright Leaf tobacco), and the like, also can be used in place of or together with nicotine. The same procedure used for the addition of flavor(s) can be followed for the addition of nicotine.
The third step is the formation of the gel product. Different binder agents, as disclosed hereinabove, can be used in this step. The binder is added at a ratio of about 5.0% to about 60.0 % mass/mass over the weight of the flavored (with or without nicotine) syrup, including from about 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60% mass/mass. The viscosity control can be improved by the use of a salt, such as sodium chloride.
In other embodiments, preservatives, as disclosed hereinabove, can be added at a concentration of about 0.5% to about 2.0% mass/mass, including about 0.5, 1.0, 1.5, and 2.0% mass/mass. In further embodiments, dyes and/or bleaching agents also can be present in a concentration between about 0.01% to about 10.0% mass/mass, including about 0.01, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10% mass/mass. The binder agent and/or other auxiliaries (such as preservatives and coloring agents) are added to the flavored syrup solution under continuous stirring, kept for between about 5 to about 50 minutes (mechanical stirrer at a speed of about 1,000 rpm to about 3,000 rpm depending on the volume that is being prepared).
Accordingly, the presently disclosed subject matter provides method for preparing a dry gel flavor composition, the method comprising: (a) preparing a syrup by mixing 1% to about 99% of one or more humectants and from about 1% to about 99% of at least one source of sugar; (b) adding from about 1.0% to about 45% of one or more flavors to the syrup with stirring to form a flavored syrup; (c) adding from about 5.0% to about 60% wt/wt of one or more binder agents to the flavored syrup with stirring to form a viscous material; (d) adding water to the viscous material with stirring; and (e) placing the viscous material in a mold for a period of time at about 5 °C. The molded material can then be cut into fine pieces for use as a tobacco substitute in a hookah appraratus.

The solution was let to cool down to 40°C and 0.10-0.15 grams of grape flavor were added to the solution which was stirred at 1,000 rpm for 10 minutes. After cooling to room temperature, a clear dry gel product was obtained. It was cut into a droplet shape and a small square shape, and used as a tobacco substitute in hookahs.
