Bitter substances in functional foods and beverages can act as nutraceuticals, offering potential health benefits. However, their unpleasant sensory impact reduces the consumption of these foods. Consequently, the discovery of bitter masking compounds is crucial for enhancing the intake of bioactive compounds in functional foods and beverages. Bitter taste is mediated by TAS2Rs, a sub-family of G-protein-coupled receptors. TAS2R14 is especially pivotal in the perception of bitterness, as it is one of the most broadly tuned bitter receptors. In this study, allspice was extracted and purified to yield five single compounds based on sensory guided fractionation. The structures of each compound were determined based on nuclear magnetic resonance (NMR) and high-resolution mass spectrometry (HR-MS). In a sensory evaluation, compound exhibited bitter masking activity against quinine. Molecular docking analysis revealed that compound could act as an antagonist of the TAS2R14 bitter receptor.

Peptide aggregation inevitably occurs during hydrolysis, and insoluble peptide aggregates (ISPA) are used as feed for animals due to their poor water solubility and unpleasant bitter flavor. Ultrasound was used to fabricate soy peptide nanoparticles by reassembling ISPA, followed by spray-drying encapsulation to develop low-bitterness peptide microcapsules with soluble soybean polysaccharide (SSPS) and stevioside (STE) as wall materials. Powder properties, bitter taste, and the morphology of the microcapsules were evaluated.

Chasteberry extract offers considerable phytotherapeutic benefits, particularly in alleviating premenstrual syndrome (PMS) symptoms. However, its hydroalcoholic nature leads to a bitter taste and a burning sensation, presenting challenges for direct consumption or incorporation into new food products. This study aimed to address these issues by encapsulating concentrated chasteberry extract using spray-drying with Arabic gum, followed by spray-chilling with vegetable fat as carriers.

Article Synopsis
- - The Fast Melt Tablet (FMT) is a new type of quickly dissolving tablet that uses cocoa butter to melt at body temperature, enhancing its effectiveness when taken orally.
- - The study aimed to improve the taste of FMT containing memantine hydrochloride by using artificial sweeteners like aspartame and acesulfame K; six formulations were tested to find the best flavor masking.
- - Formulation T7, using 30mg of aspartame, was found to effectively mask the bitter taste and has desirable properties for commercialization, showing potential as an easy-to-take treatment for Alzheimer's disease.
Pediatric Orally Disintegrating Tablets (ODTs) with Enhanced Palatability Based on Propranolol HCl Coground with Hydroxypropyl-β-Cyclodextrin.

Background: Propranolol, largely prescribed as an antihypertensive and antiarrhythmic drug in pediatrics, is characterized by a bitter taste and an astringent aftertaste. Currently, the therapy requires crushing of tablets for adults and their dispersion in water many times a day, leading to loss of dosing accuracy, low palatability, and poor compliance for both patients and caregivers.
Objectives: This work aimed to exploit cyclodextrin complexation by cogrinding to develop orally disintegrating tablets (ODTs) endowed with reliable dosing accuracy, good palatability and safety, ease of swallowability, and ultimately better compliance for both pediatric patients and caregivers.

Ensuring children adhere to their prescribed medication can be challenging, particularly when a large number of medicines on the market consist of unpalatable drugs and difficult to swallow dosage forms. Sugar-based oromucosal films are easy to administer dosage forms across all age groups within the paediatric population, as they eliminate the need for swallowing or water intake and can contribute to enhancing palatability and medicine adherence. In the current study, electrospun and 3D printed oromucosal films of chlorpromazine hydrochloride (CHZ), a bitter drug, were developed based on pullulan, a natural polysaccharide, and an array of sweeteners.
