Assistance needed troubleshooting beverage development process and formulation:
We formulate a sugar-water liquid for studying insects in captivity—in both laboratory and hobbyist settings. Our formulation relies on the use of a strong base (NaOH or KOH) at a concentration of about 0.0475M as a phagostimulant (to increase feeding response). In addition, the resulting pH appears sufficient to inhibit growth of most microorganisms for a sufficient period of time.
Unfortunately, when the bottled product is opened and exposed to air, the resulting reaction from the absorption of CO2 into the aqueous solution—then forming carbonic acid—appears to neutralize the base over a period of time, degrading the quality of the product. The phagostimulatory properties are reduced, and the solution becomes more susceptible to microbial and fungal activity.
The product ingredients are as follows (listed by weight):
> Sodium chloride (required phagostimulant)
> Potassium hydroxide (required phagostimulant)
> EDTA tetrasodium
> Food dye
The goal of this project is to receive instruction so as to improve our small-batch manufacturing process (200 L), and to reformulate or otherwise find a way to increase product stability and mitigate the product degradation that occurs naturally when the bottled solution is exposed to air, such as during normal usage. A special consideration is that any reformulation mustn't negatively affect feeding receptivity.
We expect the underlying requirements for the project to be completed within a few weeks, at most. However, we will keep the project open after payment, so any future concerns related to the scope of work may be addressed by the same contractor.
