Transforming Cocoa Production in Vietnam

Japanese Hydro Powtech Inc. (NHP), a company based in Nagaoka City, Niigata, has embarked on an innovative joint research project in Vietnam with its partners, Lotte Corporation, Canto University, and Takeshow Food Vietnam. This collaborative effort began with a first phase of research on May 24, 2023, and has now transitioned to an experimental phase on cocoa farms, as a signing ceremony on October 9, 2025, marked the start of their second research phase.

Research Background

Cocoa beans, integral to chocolate production, undergo fermentation and drying after being harvested from cocoa pods. Remarkably, about 80% of the total weight of cocoa fruits comes from the outer shell, which is often discarded on cocoa farms without any utilization. This waste not only takes time to decompose naturally but can also promote pathogen growth that decreases the yield of cocoa beans and subsequently the income of cocoa farmers. Therefore, it's crucial to develop appropriate methods for processing and utilizing cocoa pods effectively.

First Phase of Research Findings

In the initial joint research phase, the team utilized hydrolysis technology to sterilize and crush cocoa pods, then spread the processed material on the fields in the Mekong Delta region of southern Vietnam. The results were promising: applying hydrolyzed cocoa pods significantly enhanced the growth of cocoa seedlings and improved soil conditions.

The Next Steps

For the second phase of this research, the team will further examine the impact of applying hydrolyzed cocoa pods on cocoa bean yields. This project aims to address environmental issues in cocoa-producing areas while promoting a sustainable, resource-circular society.

About Japanese Hydro Powtech Inc.

Founded in 2014, NHP leverages its unique hydrolysis technology for the planning, development, manufacturing, and sale of food products. This technology drastically reduces the time required for breakdown compared to conventional methods, without using any chemical agents and with minimal energy consumption, thereby lowering environmental impacts. The resulting products can be labeled as “made from the original material,” allowing for allergen-free options and applications in alternative dairy and meat sectors. The partnership with Lotte Corporation that began in December 2022 aims to maximize the effective utilization of cocoa resources.

About Lotte Corporation

Lotte, a leader in the chocolate industry since the launch of Ghana Milk Chocolate in 1964, has built a strong portfolio featuring high-quality brands such as Rummy, Crunky, and Tiramisu Chocolate. The corporation continues to expand its influence by acquiring various brands and investing in sustainable sourcing methods that directly connect with cocoa farmers. Their collaboration with Japanese Hydro Powtech focuses on leveraging innovative hydrolysis technology to create sustainable practices and address social challenges within the chocolate domain.

About Canto University

Established in 1966, Canto University is one of Vietnam's national key universities, positioned in the southern city of Canto. It plays a vital role as a major educational and research institution, focusing on agricultural development in the Mekong Delta and serving over 52,000 students across various disciplines.

Conclusion

The joint research initiative between NHP, Lotte, and Canto University is more than just an experiment; it represents a significant step toward sustainable agricultural practices in cocoa farming. By creating pathways for recycling and effective utilization of cocoa waste, these organizations are not only addressing environmental challenges but also enhancing the livelihoods of cocoa farmers, opening new avenues for the future of cocoa production.
