Morus and University of Illinois Collaborate on Groundbreaking Study

Morus Inc., headquartered in Chiyoda, Tokyo, has announced the publication of research conducted in collaboration with the University of Illinois in the Journal of Insects as Food and Feed. The study, set to be published in the online edition on December 19, 2025, reveals groundbreaking findings regarding the bioavailability of zinc in silkworm powder compared to plant sources.

Significant Research Findings

This study marks the first investigation into the mineral bioavailability in Morus's silkworm powder. The researchers found that the bioavailability of zinc in silkworm powder was almost twice as high as that found in mulberry leaves. A key point of this study is its confirmation of silkworms' ability to enhance the efficiency of digesting and absorbing plant-based minerals, functioning as a “bio-reactor capacitor.” This role of silkworms has been scientifically validated for the first time, offering promising insights into how insects can improve nutrient assimilation from plants.

The publication of this academic paper represents a major step toward demonstrating the potential and market value of novel foods, enhancing the importance of silkworms in the nutritional landscape.

Background of the Research

Zinc is an essential mineral that the human body cannot produce and is vital for maintaining health. However, the zinc present in plant-based foods is often poorly absorbed. Zinc deficiency may lead to various health issues, such as:

• - Altered taste and smell
• - Skin conditions and irritations
• - A decline in immune function, leading to increased infection rates
• - Anemia and fatigue

Globally, it’s estimated that around 20% of the population may not meet their zinc intake needs, highlighting a significant public health concern.

Despite the importance of zinc, research on its biological bioavailability has been limited. This study utilized Morus's silkworm powder, which contains plant-based zinc derived from mulberry leaves, to explore its potential.

Methodology of the Research

The study employed a bioassay method involving animals, specifically hatchlings, to evaluate the bioavailability of zinc. Bioassay techniques assess the biological activity of compounds by observing the responses of living organisms, allowing for a deeper understanding of complex interactions that chemical analyses cannot easily reveal. This method is widely used in various sectors, including drug development and toxicology.

Using hatchlings fed with silkworm powder, the researchers examined the relationship between the inorganic zinc content and the amount administered, analyzing the utility of zinc in silkworm powder.

Results of the Research

Using a 100% standard for inorganic zinc (ZnSO₄·H₂O), the study confirmed that the bioavailability of zinc in silkworm powder was 175%, significantly higher than that of zinc derived from mulberry leaves (91%). This research provides the first evidence that silkworms can enhance the digestive efficiency of plant-based minerals, acting as a “bio-reactor capacitor.”

About the University of Illinois

The University of Illinois system, comprised of three campuses, is renowned for its research contributions, particularly in engineering and natural sciences. The Urbana-Champaign campus is often recognized as a leading public Ivy and has produced 30 Nobel laureates as of 2022. In the 2023 Times Higher Education World University Ranking, it was ranked 4th, underscoring its global academic prestige.

Comments from Morus CEO

Morus's CEO, Ryo Sato, expressed pride in the collaboration with the University of Illinois: “It’s an honor to achieve results with one of the world’s leading research institutions in nutrition. We hope our joint research can illuminate the potential of silkworms in material science and contribute to societal implementation.”

Insights from Morus' Nutrition Research Head

Seiji Aoyagi, head of nutrition research at Morus, noted the importance of bioavailable zinc: “Many individuals, particularly those consuming plant-centric diets, struggle to obtain sufficient zinc. This deficiency can compromise immune health and overall quality of life. The validation of silkworms' role in enhancing plant-based mineral absorption is a significant step in nutritional science.”
