| Abstract | This research presents an integrated approach to the development of a modern carbonated beverage product by combining formulation science and packaging design. The project is divided into two key phases. Phase 1 – Internal Design Platform focuses on optimizing the beverage’s sensory profile, particularly balancing sweetness, sourness, and carbonation, which are critical to the overall drinking experience. Using sensory evaluation, instrumental analysis, and mathematical modeling—including the Sweet-Sour Taste Sensory Strength Variation Model (SSTVM) and Weber–Fechner Law—the study identifies synergistic and antagonistic interactions between sucrose, citric acid, and carbonation. Response Surface Methodology (RSM) and machine learning algorithms were employed to determine the ideal formulation that maximizes consumer acceptance. Key findings reveal that citric acid elevates the sweetness threshold of sucrose, while carbonation modulates both sweet and sour perception, highlighting the complex interplay of taste sensations. Phase 2 – External Design Platform addresses the packaging design of the 330-ml beverage bottle, aimed at aligning with the lifestyles and aesthetic preferences of young consumers. The bottle features an ergonomic shape with a bear-paw-shaped watermark for enhanced grip and structural stability, along with fruit-inspired graphics, minimalist labeling, and options for matte or glossy finishes. Through consumer surveys and interviews, the study identifies key drivers of purchasing decisions such as usability, visual appeal, and social-sharing compatibility. To support design translation, methodologies including Quality Function Deployment (QFD), House of Quality (HoQ), and Product Design and Development (PDD) were used. Additionally, Linear Programming (LP) was applied to optimize material usage, minimize production waste, and evaluate trade-offs between packaging shapes for cost-efficiency and storage performance. The research highlights the importance of aligning internal sensory attributes with external product design to create a cohesive and emotionally resonant beverage experience. The integration of computational modeling, user research, and eco-efficient design strategies supports the development of a “Trendy-Bottle Design Platform” that encourages creativity, real-time collaboration, and rapid prototyping. Overall, the study contributes a holistic framework for beverage innovation that responds to both consumer desires and industry sustainability goals. |
