The most critical question being overlooked is: “What is the true total energy cost of the drying step when we account for the inefficiencies of heat-based evaporation, and how can we eliminate it entirely through innovative formulation and process design?”
Most manufacturers accept water removal (drying) as an unavoidable necessity, but this assumption masks a huge energy waste. Traditional gummy production relies on cooking a slurry of gelatin, sweeteners, and water to very high temperatures-intentionally adding excess water to ensure proper mixing and flow-only to then spend hours in drying tunnels or rooms to evaporate that same water. The energy required to heat, maintain, and evaporate that water is enormous, and the process has inherent inefficiencies: heat losses, long cycle times, and the need for dehumidification and air handling equipment.
Ignoring this question means missing the opportunity to adopt energy-efficient alternatives that could slash utility costs. For example, low-moisture or no-dry formulations, such as those using non-gelatin gelling systems (pectin, starch, or gum-based), can produce gummies that set without the need for added water. These processes often require less cooking time and lower temperatures, directly reducing energy consumption. Additionally, techniques like vacuum drying or continuous drying systems can cut drying time by 50% or more, but they are rarely considered because “everyone dries.”
Furthermore, the energy efficiency of the drying step is rarely benchmarked. Most facilities don’t track the kWh per kilogram of water removed, or the cost per batch of drying. Without this data, manufacturers cannot identify that the drying stage may be responsible for 60-80% of the total energy used in gummy production. The real question is not “How do we optimize drying?” but rather “Can we eliminate drying altogether?” This shift in mindset is what separates a truly efficient gummy manufacturing line from a wasteful one-and it’s the question most teams are afraid to ask because it challenges decades of conventional wisdom.
To move forward, manufacturers should ask: What is the minimum water content our recipe truly requires, and can we reformulate with a higher solids content from the start? By focusing on the water removal step as a design variable rather than a fixed necessity, you unlock the single biggest lever for energy savings in gummy production.
