The dispersed phase comprises at least one active component. The at least one active component is one or more cannabinoids. Cannabinoids are a class of natural or synthetic chemical compounds, some of which are known to act on cannabinoid receptors (i.e., CB1 and CB2) in cells that repress neurotransmitter release in the brain. Other molecular targets of cannabinoids have been identified and are discussed in Ibeas Bih, C., Chen, T., Nunn, A.V.W. et al. Molecular Targets of Cannabidiol in Neurological Disorders. Neurotherapeutics 12, 699–730 (2015). Cannabinoids are cyclic molecules exhibiting particular properties such as the ability to easily cross the blood-brain barrier. Cannabinoids may be naturally occurring (phytocannabinoids) from plants such as cannabis, (endocannabinoids) from animals, or artificially manufactured (synthesised cannabinoids). Cannabis sativa species express at least 120 different phytocannabinoids (see ElSohly, M.A.; Radwan, M.M.; Gul, W.; Chandra, S.; Galal, A. Phytochemistry of Cannabis sativa L. Prog. Chem. Org. Nat. Prod.2017, 103, 1–36) , and these may be divided into subclasses, including cannabigerols, cannabichromenes, cannabidiols, tetrahydrocannabinols, cannabinols and cannabinodiols, and other cannabinoids, such as cannabigerol (CBG), cannabigerolic acid (CBGA), cannabichromene (CBC), cannabichromenic acid (CBCA), cannabidiol (CBD), cannabidolic acid (CBDA), tetrahydrocannabinol (THC), including its isomers Δ6a,10a-tetrahydrocannabinol (Δ6a,10a- THC), Δ6a(7)-tetrahydrocannabinol (Δ6a(7)-THC), Δ8-tetrahydrocannabinol (Δ8-THC), Δ9- tetrahydrocannabinol (Δ9-THC), Δ10-tetrahydrocannabinol (Δ10-THC), Δ9,11- tetrahydrocannabinol (Δ9,11-THC), tetrahydrocannabinolic acid (THCA),cannabinol (CBN), cannabinolic acid (CBNA), and cannabinodiol (CBDL), cannabicyclol (CBL), cannabivarin (CBV), tetrahydrocannabivarin (THCV), cannabidivarin (CBDV), cannabichromevarin (CBCV), cannabigerovarin (CBGV), and cannabigerol monomethyl ether (CBGM). Naturally occurring cannabinoids (phytocannabinoids) are generally present in raw plant material in their carboxylated form. These acids can be decarboxylated by moderate to high temperature (such as from heating or processing within an extraction process), UV exposure or prolonged storage to form the more active decarboxylated form. In this regard, cannabidiol (CBD) and cannabidolic acid (CBDA) are the respective decarboxylated and carboxylated forms. In one embodiment, the cannabinoid is selected from cannabigerol (CBG), cannabigerolic acid (CBGA), cannabichromene (CBC), cannabichromenic acid (CBCA), cannabidiol (CBD), cannabidolic acid (CBDA), tetrahydrocannabinol (THC), including its isomers Δ6a,10a-tetrahydrocannabinol (Δ6a,10a-THC), Δ6a(7)-tetrahydrocannabinol (Δ6a(7)-THC), Δ8-tetrahydrocannabinol (Δ8-THC), Δ9-tetrahydrocannabinol (Δ9-THC), Δ10-tetrahydrocannabinol (Δ10-THC), Δ9,11-tetrahydrocannabinol (Δ9,11-THC), tetrahydrocannabinolic acid (THCA),cannabinol (CBN), cannabinolic acid (CBNA), and cannabinodiol (CBDL), cannabicyclol (CBL), cannabivarin (CBV), tetrahydrocannabivarin (THCV), cannabidivarin (CBDV), cannabichromevarin (CBCV), cannabigerovarin (CBGV), and cannabigerol monomethyl ether (CBGM).

The ingestible product may be in the form of a tincture, beverage, chew, tablet, pastille, gum, melt or lozenge. In one embodiment, the ingestible product is in the form of a chew. When the product is a chew, it is chewable, meaning the composition has a mild resilience or "bounce" upon chewing, and possesses a desirable degree of malleability. A product in chewable form may be entirely dissolving, or may be in the form of a non- dissolving gum in which only certain components (e.g., active components, flavor, sweetener) dissolve, leaving behind a non-dissolving matrix. Chewable embodiments generally include a binder (as discussed below), such as a natural gum, pectin, gelatin, agar, carrageenan, starch, or a combination thereof. In some embodiments, the binder comprises or is pectin. Representative chew products and products may incorporate about 10 weight percent or less of at least one active ingredient, around 1 to 5 weight percent of a binder (e.g. pectin, agar, carrageenan, starch, or a combination thereof), about 0.01 to about 2 percent sweetener, at least about 50 percent of one or more sugar alcohols, and about 0.1 to about 5 percent of at least one flavoring agent, based on the total weight of the product. The particular percentages and choice of ingredients will vary depending upon the desired flavor, texture, and other characteristics. In some embodiments, the composition in chewable form comprises pectin and an organic acid, along with one or more sugars or sugar alcohols in an amount by weight of at least 50%, based on the total weight of the composition. In some embodiments, the sugar alcohol is a combination of isomalt and maltitol. Generally, the pectin is present in an amount of from about 1 to about 5% by weight, based on the total weight of the composition, and an organic acid, a gelation agent, or both are present to crosslink the pectin. In some embodiments, a sugar substitute may be an alternative to sugar alcohols, or used in combination with one or more sugar alcohols. Suitable sugar substitutes include allulose, soluble tapioca fiber, inulin, and combinations thereof. Ingestible products in the form of a chew may contain various amounts of water. For example, the water content of the chew product may be provided within a specified range so as to dictate the final form of the product. The water content of the chew products described herein, prior to use by a consumer of the product, may vary within such ranges according to the desired properties and characteristics, in addition to dictating the final form of the product. Since the amount of water in the chew may also impact the textural profile of the chew (more water leading to a softer chew), there can be limits on the amount of water that would ideally be included in the chew. However, since the emulsion can be a source of water in the chew, it is preferable to use an emulsion which can sustain a high active loading since then the amount of emulsion (and thus water) can be controlled. For example, chew-type products typically possess a water content in the range of about 10 to about 25 weight percent, , such as from about 10 to about 20 weight percent, such as from about 12 to about 23 weight percent such as from about 12 to about 18 weight percent, based on the total weight of the product. Typically, the chew-type product comprises about 22 weight percent water, based on the total weight of the product. In some instances, it can be desirable for the ingestible chew to have a low water activity (“aw”). Water activity values can be obtained using a resistive electrolytic, a capacitance or a dew point hygrometer. In particular, it is desirable if the water activity of the chew is 1.0 awor less. In one embodiment, the water activity of the chew is 0.9 awor less. In one embodiment, the water activity of the chew is 0.8 aw or less. In one embodiment, the water activity of the chew is 0.7 awor less.

Examples Influence of gum acacia on emulsion particle size Example 1) When a dispersed phase is dispersed in a continuous phase to form an emulsion, the particle size of the dispersed phase particles can be an important parameter. In particular, changes in particle size over time can indicate that the emulsion is less stable. Emulsions were prepared according to Table 1 and Table 2 below. In particular, the dispersed phase carrier was combined with the active and the combination mixed whilst heating to around 60°C. Water, glycerol and the emulsifier were mixed and then combined with the dispersed phase and mixed under high sheer at 16000rpm for 10-20 minutes until a particle size of 1400nm or less is achieved. Then, further mixing of the continuous phase and the dispersed phase was undertaken using a microfluidizer at a pressure of 20k psi. The mixing time in this step depends on the capacity of the microfluidizer but generally until the reduction in particle size stabilizes.

The particle size was then measured on day 0 (the day of preparation) and then after ageing at 57°C for 1 day (so as to simulate longer term ageing at a lower temperature). Particle size measurements were then taken using a Horiba Particle size analyzer, nano mode–Model # SZ-100-Z.

Example 2) A further emulsion was prepared according to the method of Example 1, but using composition as set out in Table 4 below: Table 4 Sample 5 Ingredient (%w / w) Oil 14.85% CBD 7.55% Vitamin E 0.15% Gum acacia** 11.25% Water 33.10% Glycerol 33.10% ** Ticaloid Acacia Max This emulsion was stored for an extended period of time and the change in particle size assessed using a similar methodology as described above. The results are shown in Table 5: Table 5 Particle Density Viscosity Potency active Time Storage awsize pH (g / mL) (cP) (CBD) (mg / g) (nm) Fridge ≈500-800 T0 0.81 780 4.42 1.09 ~75± 5% (4-6°C) Month Fridge ≈500-800 0.81 850 4.52 1.10 ~75± 5% 6 (4-6°C) As is to be noted, the particle size change after 6 months’ storage was minimal, at around 8% of the original particle size and still at the nm level. This shows that gum acacia as the sole emulsifier is above to produce a stable emulsion. PK study – Ability to effectively deliver cannabinoids Example 3) In order to determine the suitability of the emulsion to deliver CBD, a pk study was undertaken whereby beverages (in the form of shots) and chews were prepared using the inventive emulsion. The bioavailability and pharmacokinetics of the inventive delivery system were assessed in comparison to conventional oil delivery systems. The most common route of administration of CBD is oral ingestion, dissolved in an oil solution. Therefore, an oil-based delivery system is a standard for market-based delivery systems The test delivery systems are outlined in Table 6 below: Table 6 Ingredient Reference 5 Reference 6 Sample 6 Sample 7 (Arm D – (Arm A – (Arm H – (Arm C – RTO000078 RTO000075 RTO000082 RTO000077 Chew) Tincture) Chew) Shot) CBD concentration 30mg / 4g 30mg / mL 30mg / 4g 1mg / ml CBD dose 60mg 60mg 60mg 60mg Format Chew Tincture Chew Shot Water 23.00% - 22.00% 88.71 Sodium Citrate (dihydrate) 0.70% - 0.70% Pectin HM Slow Set 2.90% - 2.90% - Powder Xylitol 10.00% - 10.00% - Glucose Syrup - 42 DE - 56.50% - 55.60% - 19.4% water Sucrose (fine, granulated) - - - 5.00% Glycerin 3.00% - 3.00% 4.20% Colorant 2 - 102 - Yellow 0.18% - 0.18% - - TARTRAZINE (1% solution in Glycerol:Water 75:25) (0.0025% tartrazine in final formulation = 25ppm) Flavor - Lemon - Bell 0.30% - 0.30% - Water From Emulsion 0.00% - 0.00% - Glycerol from Emulsion 0.00% - 0.00% - Lecithin from Emulsion 0.00% - 0.00% 0.20% Gum Acacia (Ticaloid 0.00% - 1.10% 0.03% Acacia Max) Organic Sunflower oil 1.50% 96.00% 1.50% 0.20% from Emulsion CBD (isolate) 0.80% 3.00% 0.80% 0.10% Vitapherole T90 0.00% 1.00% 0.00% Sodium Ascorbate - E 301 0.10% - 0.10% 0.09% Sodium Benzoate - - - 0.06% Trisodium Citrate - - - 0.74% Dihydrate Citric acid 2.00% - 2.00% 0.67% Nutra Oil XCC 01 - Each delivery system was incorporated into a final format and subsequently administered to 36 adult subjects.

[0003] As is apparent, Samples 6 and 7 using the inventive emulsion system resulted in a Cmax value which was well above that for References 5 and 6 (which used a conventional oil based system). Moreover, Samples 6 and 7 resulted in an earlier onset of cannabidiol detection, and also an earlier peak relative to References 5 and 6. Further Stability study relating to CBD derivatives Example 4) Sample 6 (referred to as Arm H) and Reference 5 (referred to as Arm D) were also tested for CBD derivatives over a period of storage at 25°C and 60 relative humidity. In particular, the samples were tested for CBD-HQ at T0 (immediately after production), T1 (1 month after production), and TF (6 months after production) using Liquid chromatography–mass spectrometry. As is shown by Figure 1, chews containing the oil based system of Reference 5 showed greater development of CBD-HQ than chews containing the inventive emulsion system. Additionally, CBD levels were monitored throughout the same period (but using HPLC), and Figure 2 shows that Sample 6 maintained higher levels of CBD throughout the study period. Accordingly, it has been demonstrated that using the inventive emulsion system is superior to conventional oil based delivery systems. Moreover, as illustrated by Examples 1) and 2), the inventive emulsion system also displays greater stability than other emulsion systems. As a result, the inventive emulsions system is able to provide a superior delivery system both in terms of cannabinoid delivery and emulsion stability. Further Study with additional emulsions Example 5) A further emulsion was prepared generally using the methodology outlined for Example 1). This further emulsion contained 100mg / g of active (in this case CBD) alongside modified starch. The modified starch was waxy maize based starch modified with Octenyl Succinic Anhydride (OSA).
