Liposomal Sleep Beverage Formulation Case Study: Improving Color, Flavor and Commercial Readiness
Customer: A functional beverage brand in Singapore
Application: Ready-to-Drink Sleep Support Beverage
Core Ingredients: Co-Loaded Liposomal GABA + Chamomile Extract + Magnesium Bisglycinate
Project Background
The customer was developing a ready-to-drink sleep support beverage based on our co-loaded liposomal ingredient system. During pilot-scale development, the product encountered noticeable issues with both appearance and flavor, affecting final formulation approval and the planned launch schedule.
The finished beverage had a dark color and limited clarity, which did not match the brand's desired light and soothing product positioning. At the same time, the beverage had a noticeable herbal bitterness and heavy aftertaste. Simply increasing sweetness was not sufficient, while the customer also wanted to maintain a clean-label formulation without artificial flavors.
Our Solution
Natural Field's formulation team analyzed the complete ingredient and formulation system to identify the key factors affecting color and flavor.
The analysis showed that the chamomile extract used in the original formulation was one of the major contributors to the darker color and pronounced herbal bitterness, with differences related to raw material source and extraction process.
Based on the application requirements, we developed a two-step optimization approach while maintaining the original co-loaded liposomal formulation concept.
Raw Material Optimization
We replaced the original chamomile extract with a light-colored, selectively purified chamomile extract. By controlling color- and bitterness-related components at the raw material level, we reduced their impact on the finished beverage and established a more stable foundation for further formulation adjustment.
Natural Flavor Balancing
We introduced a refreshing natural fruit powder to gently balance the herbal taste. No artificial flavors were added, helping create a cleaner and more refreshing flavor profile while supporting the customer's clean-label positioning.
Project Results
The optimized formulation delivered noticeable improvements in both appearance and flavor:
- Improved Color: The finished beverage became visibly lighter with better visual clarity, better matching the intended product positioning.
- Improved Flavor: Herbal bitterness and aftertaste were significantly reduced, resulting in a cleaner and more balanced taste profile that passed the customer's internal sensory evaluation.
- Commercial Readiness: After successful pilot validation, the customer approved the optimized solution and placed a 120 kg bulk order, supporting the product's transition toward commercialization.
From Ingredient Supply to Formulation Solutions
This project demonstrates that Natural Field provides more than functional ingredients. We also support customers with formulation analysis, raw material selection, application optimization, and product development.
By combining ingredient optimization, formulation expertise, and co-loaded liposomal delivery technology, we help customers address practical formulation challenges and move functional ingredients from laboratory validation toward commercial application.
FAQ
Q: Can you help improve the color and flavor of functional beverages?
A: Yes. We can analyze the effects of raw materials and formulation components on color, taste, solubility, and other application characteristics, then optimize the formulation accordingly.
Q: Can you help develop a formula based on our existing product or benchmark sample?
A: Yes. We can support formulation analysis, raw material selection, sample development, and iterative testing based on your product requirements or benchmark sample.
Q: Can you provide formulation support in addition to supplying ingredients?
A: Yes. Our technical team can support customers throughout the product development process, from ingredient selection and formulation adjustment to sample testing and application optimization.
