ROI Calculation Logic

This technology enables the production of high-value beverages with enhanced ethyl caproate production. Assuming a 10% increase in product unit price from $3.33/bottle to $3.67/bottle (AI est.). For an annual production scale of 500,000 bottles, the revenue increase could be ($3.67/bottle - $3.33/bottle) × 500,000 bottles = ~$165K/year (AI est.). Furthermore, new customer acquisition and brand value enhancement from novel flavors could lead to an estimated annual revenue increase of ~$1M (AI est.).

Speed to Market
6× faster than in-house development
Developing new brewing yeast, including strain selection, breeding, optimization of culture conditions, and safety evaluation, typically takes over 3 years. However, this technology provides already established novel breeding strains, registered as NITE P-03177 and NITE P-03178, significantly shortening the basic research and breeding phases. Furthermore, existing licensing records indicate some validation data is available, allowing licensees to potentially apply this technology to their products and enter the market in as little as 6 months.
