Abstract
Background: This article highlights the formulation of a solid Δ9-tetrahydrocannabinol (THC)-loaded ingestible prepared from pure THC distillate. Methods: A THC-containing ethanol-assisted cannabinoid nanoemulsion (EACNE) was created using a solvent displacement technique. Subsequently, the EACNE was converted to a solid powdery material while still retaining its THC potency, a format uniquely suited for "microdosing" applications. Results: EACNE had an average lipid droplet size of ∼190 nm, with a polydispersity index of 0.15, and an average droplet ζ potential of -49±10 mV. The nanoemulsion (NE) was colloidally stable for at least 6 weeks, with no meaningful change in cannabinoid potency over the experimental period, as determined by high-performance liquid chromatography analysis. The EACNE remained stable when subjected to physical stresses such as heat, freeze/thaw cycles, carbonation, dilution to beverage concentrations, high sucrose concentrations, and a pH range between 5 and 8. The microencapsulated EACNE demonstrated limited free-flowing behavior but was freely redispersible in water without any visible phase separation. Conclusions: We report the design, creation, and characterization of a THC NE generated without the use of specialized equipment, such as a microfluidizer or a high-pressure homogenizer. This emulsion could readily be converted to a water-redispersible powder. This embodiment is particularly suited for THC "microdosing," a practice that might decouple the health benefits of THC from its psychotropic effects.

Physicochemical stability and in-vitro bioaccessibility of concentrated γ-Oryzanol nanodispersions fabricated by solvent displacement method. Food Chem 2022; 382:132300. [PMID: 35134726 DOI: 10.1016/j.foodchem.2022.132300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2021] [Revised: 01/27/2022] [Accepted: 01/28/2022] [Indexed: 11/20/2022]
Abstract
Concentrated γ-Oryzanol nanodispersions were fabricated using milli-Q water (no emulsifier) or 0.1% (w/w) polysorbate 80 (T80), modified lecithin (ML) or sodium caseinate (SC) as emulsifiers. The freshly prepared nanodispersions had comparable particle diameter (118 to 157 nm), γ-Oryzanol concentration (1.75 to 1.92 mg mL-1) and free-radical scavenging activity (59 to 62%) and had negative ζ-potentials (-22 to -59 mV), indicating that both γ-Oryzanol and emulsifier coexisted on the particles' interface. The nanoparticles had superior physicochemical stability up to 30 days of storage at 5 °C and were successfully autoclaved without excessive growth or aggregation. Nevertheless, they showed distinct physical stability upon storage at specific environmental conditions, which affected their In-vitro gastrointestinal digestion. Comprehensively, emulsifier-free nanodispersions were sensitive to acidic pH, NaCl and CaCl2 addition. ML and SC coated nanoparticles were sensitive to Ca2+ ions, while T80 stabilized nanodispersions resisted to all environmental stresses, resulting in optimal simulated intestinal absorption.
