Definitions

  • the technical field of the invention is that of rolling cigarette papers and more particularly the adhesive thread used to stick the cigarette paper by reactivation by licking, also called gum used to stick the cigarette paper, its manufacturing process and the cigarette paper obtained.
  • cannabinoids particularly cannabidiol or CBD
  • CBD cannabidiol
  • rolling papers and gum are made from aqueous solutions. Water and oil are not miscible, making it difficult to produce these cannabinoid-enriched rolling papers.
  • the paper was also infused with cannabinoids obtained from an oil extract of the cannabis plant, as in the documents US2018/360103 , US2019/390408 And WO2017/196840 . Since cannabis extract containing cannabinoids is an oil that is not miscible in water, an emulsifier must be used to allow the cannabinoids to disperse evenly in the papermaking process. These emulsions are additives that complicate the paper formulation and make it less natural.
  • a first aspect of the invention relates to a gum of plant origin, for rolling cigarette paper comprising a defined percentage of dry extract, said gum is characterized in that it comprises a mixture of cannabinoids and edible oil, the edible oil being present in the mixture in a proportion p such that 0% ⁇ p ⁇ 80% by mass of the mixture.
  • the cannabinoids being soluble only in the oil and the gum being intended to be brought to the mouth since it must be re-activated by licking once coated, smoked and swallowed, it is necessary to use a minimum of the oil and for it to be edible.
  • the gum may, for example, be gum arabic initially in solid form, dissolved essentially in water with incorporation of various possible additives. This highly branched polysaccharide is edible and the resulting mucilaginous solution with high dry extract is used here for its adhesive properties, it is intended for the area coating of rolling cigarette paper, the mucilaginous solution is ready to use.
  • the dry extract (SE) corresponds to the material remaining when all the water has been removed from the preparation.
  • the maximum quantity of edible oil in the gum is limited to 20% by mass of the dry extract of the gum, preferably less than 16% by mass of the dry extract of the gum. With this proportion, the risks of the oil in the gum separating over time are controlled.
  • the cannabinoid is crystallized CBD and the edible oil is present in the mixture with a proportion p such that 20 ⁇ p ⁇ 80% by mass of the mixture.
  • This crystallized CBD is 99% pure, which makes it possible to optimize the quantity of CBD introduced into the gum.
  • a crude apolar cannabis extract - herein referred to as broad spectrum CBD - was used with or without oil and the edible oil is present in the mixture with a proportion p such that 0% ⁇ p ⁇ 20% by mass of the mixture.
  • the broad spectrum CBD may be derived from a crude cannabis extract with supercritical CO2 and then partially refined according to national legislation. Broad spectrum CBD requires less oil, or even almost no oil, and is therefore easier to incorporate into the gum. Broad spectrum CBD is free of THC (Tetrahydrocannabinol).
  • the edible oil is hemp oil.
  • Hemp oil has the advantage of containing few saturated fatty acids, which are not very fluid, and many polyunsaturated fatty acids, which are very fluid. It is therefore naturally very fluid at 20°C, which is a definite advantage for dispersing the oil containing the cannabinoids in the gum juice. It is indeed important that the oil is not solid at room temperature.
  • oils can be selected from the following: all vegetable oils for food use, such as olive, rapeseed, grape seed, sunflower oil, which are relatively fluid or possibly palm, coconut which are more viscous depending on production needs and/or market availability.
  • the dry extract comprises a plant exudate, preferably an acacia or gum arabic exudate.
  • this acacia exudate is preferably composed of 70% to 30% of Senegal variety and 30% to 70% of Seyal variety.
  • the composition of 70% Senegal variety and 30% Seyal variety allows to obtain the best results in its machineability and adhesiveness at a controlled cost. It is possible to limit costs by going up to 70% of Seyal variety in gum arabic by depositing more gum on the paper, because the better quality Senegal acacia is more expensive than Seyal acacia.
  • a second option is to use gum arabic made from 100% Seyal, reducing the cost.
  • a third option is to use 100% Senegal gum arabic, which gives the best results.
  • a second aspect of the invention relates to a rolling cigarette paper comprising gum with at least one of the preceding characteristics.
  • the cigarette obtained by rolling the gummed cigarette paper allows the smoker to enjoy the aroma of cannabis both when licking the paper to activate the stickiness and while smoking.
  • the gum is in the form of a net.
  • the width of the gum net can be between 3mm and 15mm, preferably between 5mm and 10mm.
  • the quantity of adhesive gum deposited by reactivation can vary between 30 and 60 mg/m over 5mm width. It is thus possible to vary the quantity of cannabinoid in the gummed paper.
  • the gum is in the form of a print.
  • the gum is deposited using a printing process, which allows it to be given any desired shape.
  • the coating area can be made by longitudinal or transverse thread, continuous or discontinuous, or in the form of patterns distributed over more than 30% of the surface of the cigarette paper sheet, which further increases the quantity of cannabinoids on the same gummed paper.
  • broad-spectrum CBD with or without oil is heated to 70°C before being introduced into the gum juice.
  • Broad-spectrum CBD is heated to 70°C in the presence or absence of oil before being introduced into the reactor. This makes broad-spectrum CBD more fluid and easier to incorporate into the gum juice.
  • the gum is stirred and heated to 70°C until the cannabinoid is completely diluted for homogeneous incorporation. Heating the gum juice facilitates the incorporation of the cannabinoid-enriched mixture into the gum juice.
  • the gum juice has a dynamic viscosity at 22°C of between 65 seconds and 115 seconds, preferably between 85 and 92 seconds.
  • This dynamic viscosity is measured with an Afnor T30.014 viscosity cup; this cup is a flow cup used to determine the flow time of a volume of liquid through a calibrated orifice and is measured in seconds of flow.
  • the cup has a diameter of 50mm and a height of 44mm with an orifice of diameter 5.8mm. Increasing the oil content decreases the viscosity while increasing the dry extract content increases it; the balance between these two components makes it possible to obtain the desired viscosity for the given process.
  • the gum juice contains between 37% and 45% dry extract. This percentage allows the desired viscosity to be obtained.
  • the SE of the gum juice will preferably be 41.0% and for broad-spectrum CBD, the SE of the gum juice will preferably be 40.7%.
  • the amount of exudate is greater than 75% by mass in the ES. This amount is necessary to ensure good paper bonding.
  • CBD cannabinoids
  • the gum is first made in the form of a mucilaginous solution, here called gum juice, which is placed on the cigarette rolling paper, then dried.
  • the dried gum must be soft enough not to crack and become sticky by wet reactivation of saliva to make the cigarette.
  • Rolling paper 1, illustrated Figure 1 shows a line of gum 2 placed along the entire length of one of the edges of the rolling paper 1.
  • the gum juice according to the invention is composed of water, a humectant such as sorbitol, optionally caramel quality E150 (a), a branched polysaccharide such as gum arabic alone or in a mixture with other natural vegetable gums, plant exudates, extracts of fruits, seeds or algae, cereals or tubers, a cannabinoid. and optionally vegetable oil.
  • the various components are solubilized in water or suspended in water. Sorbitol allows the gum to maintain a certain elasticity to prevent it from cracking after drying the gum juice, and it improves adhesion.
  • Caramel or E150 is a coloring agent, used here to give contrast to the gum line compared to the sheet and distinguish the location of the adhesive line. Gum arabic is, for proportions ⁇ 30% Senegal, a very powerful natural adhesive. The oil helps facilitate the dispersion or incorporation of the cannabinoid into the gum juice.
  • the gum juice is deposited on the paper through the nozzle of a gum machine in order to deposit a stream of gum of a constant width on the rolling paper. It is possible to choose this width between 5 and 15mm, it is also possible to deposit several streams of gum.
  • the stream being relatively narrow it is necessary that the gum juice has a certain viscosity to pass through the nozzle with a flow rate suitable for industrial manufacturing. It is also important that the gum juice becomes stable so storage of at least 24 hours is necessary and that it remains stable over time so that it can be stored at least 72 hours before use.
  • the dynamic viscosity target is set between 80s and 95s.
  • the dynamic viscosity target is set so that the gum juice can be passed through a gum press and have a stable/defined amount of gum dry matter on the finished product (rolling paper sheet).
  • the flow of juice delivered by the gum machine is indexed to the paper running speed.
  • the gum juice must be fluid enough to pass through the gum machine's supply pipes but not too fluid so as not to wet the paper too much, because humidity weakens the paper which can cause potential breakages during erasing (placing the gum on the paper) and so that the gum is dry when it leaves the drying oven. Indeed, as the paper is rewound when it leaves the drying oven, if the gum is still wet when it leaves the gum machine, the reel produced will be stuck and cannot be unwound for the following stages of notebook manufacturing.
  • FIG. 3 shows the evolution over time of the viscosity as a function of the ES rate with a stable oil percentage at 9.11%.
  • the evolution over time of the viscosity as a function of the dry extract percentage between 39% and 43% was measured, with a fixed oil quantity at 9.11% in order to establish a rule to be applied when increasing the dry extract percentage by 1%.
  • the measurement was made at 0, 3 and 9 days.
  • FIG 9 illustrates the variation of viscosity as a function of the percentage of oil in the juice and its evolution over time at 0 (d0), 3 (d3) and 8 days (d8). It can be seen that the viscosity decreases when the quantity of oil increases, but that from 25% oil (reference L3) the viscosity of the oil is no longer linear and that from 28% oil (reference L4), the juice begins to separate.
  • the limit of the proportion of oil in the preparation is therefore 25%, preferably less than 20% of the ES.
  • Curve J0 corresponds to a gum juice with oil without CBD
  • curve J1 to a gum juice with oil with crystallized CBD
  • J2 to a gum juice with oil with menthol.
  • Menthol was chosen for its similarity to CBD in terms of hydroxy and methyl groups, terpenes and the same ratio of carbon and oxygen numbers in the crude formula. It can be seen that there is a similarity between curves J0 and J1 from the 1st day.
  • the introduction of crystallized CBD into the oil has little influence on the dynamic viscosity of the gum. CBD is dissolved in the oil by heating it and mixing the mixture under agitation until the crystals disappear.
  • the paper 1 is arranged in a roll 10, it is unrolled then nozzles 30 of a gum dispenser 3 deposit the gum juice in a net 2 on the paper which is then passed into an oven 4 where the gum juice is dried. Afterwards, the paper 1 is cut, by knives 5, into strips 12 in the center of the gum net 2 then wound on reels 11. The paper 1 will then be cut into rectangles to make sheets of rolling paper.
  • the gumming is carried out with the gummer 3 at a constant speed and at a constant oven temperature 4.
  • the quantity conventionally expressed in dry gum equivalent deposited ranges from 36mg per linear meter for 5mm width to 50mg per linear meter for 5mm width.
  • the flow rate of the nozzles 30 is increased and/or the gumming speed is reduced by a certain percentage compared to the speed at lower deposit.
  • the amount of CBD incorporated into the formulation and then deposited on the paper remains less than or equal to 4.62% by mass of the ES in these tests. But if we incorporate 9% of oil comprising 20% of CBD, in the ES, we will obtain 1.8% by mass of CBD in the ES, with 16% of oil comprising 20% of CBD, in the ES, we arrive at 3.2% by mass of CBD in the ES, and with 25% of oil comprising 20% of CBD, in the ES, the CBD rate is 5% by mass in ES. According to national legislation the cannabinoid will not contain THC.
  • Juices P1 and P2 were both made with CBD-enriched oil in a proportion of 22% CBD and 78% oil.
  • CBD-enriched oil in a proportion of 22% CBD and 78% oil.
  • CBD in the ES.
  • Crystals also appear in juices S13 and S14, which contain an oil ratio of 20% and 50% respectively in the broad spectrum CBD/oil mixture, i.e., a proportion of 0.74% and 2.96% of the ES respectively.
  • the presence of these crystals is explained by a broad spectrum CBD incorporation temperature in the gum at a temperature below 60°C.
  • the juice it is necessary for the juice to be free of suspended matter, as the latter could damage the gum juice delivery pump and block the small diameter pipes between the pump and the nozzles. It is therefore necessary to heat the CBD to broad spectrum at 60°C prior to its incorporation into the juice manufacturing reactor in the presence of all additives.
  • the quantity of hemp oil in the ES is between 0% and 3% at 60°C minimum for the incorporation of broad spectrum CBD against more than 9% of hemp oil at room temperature for the incorporation of crystallized CBD with in both cases the same residual quantity of CBD in the gum (2.52% of the ES).
  • Broad spectrum CBD is difficult to integrate into gum juice, but it appears much more appropriate to pre-mix the broad spectrum CBD with the additives sorbitol and possibly caramel and oil.
  • the three-dimensional structure of the gum is more capable of trapping the broad spectrum CBD. It appears that for a high percentage of ES, candles/rises appear, whereas for lower ES (i.e. for a smaller quantity of gum added compared to the abundance of other additives, including broad spectrum CBD), these candles disappear. Analyses carried out with an infrared spectrometer on these candles have shown that they are essentially composed of CBD. Finally, it will also be possible to increase the quantity of broad spectrum CBD incorporated by also increasing the quantity of oil in the ES from 3% to 20%. Conversely, it is also possible to reduce the amount of oil used to solubilize the crystallized CBD by heating the enriched oil as well as the gum juice preparation reactor by double jacketing.
  • Hemp proteins are in the form of fine insoluble particles in the mixture, are visible in the gum and serve to give it a particular appearance.
  • the amount of hemp proteins is preferably ⁇ 3% of the ES.
