Gelatin in Agricultural Encapsulation
The search for innovative and safer agricultural solutions has led to the development of technologies that enhance the use of crop protection products such as herbicides.
In this context, gelatin-based encapsulation has emerged as an effective alternative to improve product efficiency, reduce environmental impact, and increase application safety.
This article explores agricultural encapsulation and the key role gelatin plays in this process.

What Is Agricultural Encapsulation?
Agricultural encapsulation is a technique that involves enclosing active ingredients within a protective matrix, allowing for their controlled release into the environment.
This approach extends the effectiveness of herbicides and other agrochemicals, decreases the need for frequent reapplication, and reduces losses from evaporation or leaching.
Why Use Gelatin to Encapsulate Herbicides?
Gelatin is a natural polymer derived from collagen, widely used in the food and pharmaceutical industries, and increasingly in agriculture.
Its application in herbicide encapsulation offers several advantages:
1 – Controlled release;
2 – Reduced toxicity;
3 – Biodegradability;
4 – Enhanced stability;
5 – Improved application safety.
Controlled Release
Gelatin enables the gradual release of the active ingredient, ensuring sustained herbicide action over time.
Reduced Toxicity
Encapsulation minimizes direct contact between the herbicide and the soil or water, reducing environmental impact.
Biodegradability
Unlike synthetic polymers commonly used for encapsulation, gelatin is a natural and biodegradable biopolymer. After releasing the active ingredient, the encapsulating material breaks down safely in the environment.
Enhanced Stability
Gelatin acts as a protective barrier against environmental stressors such as UV radiation, moisture, and temperature fluctuations.
This helps maintain the chemical stability of the active ingredient, resulting in greater product efficacy and reduced losses during storage and application.
Improved Application Safety
Gelatin encapsulation prevents uncontrolled dispersion of the herbicide, reducing the risk of direct exposure for farmworkers.
This contributes to improved human health and safety and helps protect local biodiversity.
How Does Gelatin-Based Encapsulation Work?
Gelatin can be used to create microcapsules or nanoparticles that enclose the herbicide.
The process involves several steps, including emulsification, crosslinking, stabilization, and drying, to form durable capsules that gradually dissolve in the environment, releasing the active ingredient in a controlled manner.
Emulsification
The herbicide is blended with gelatin in an aqueous solution, forming suspended droplets.
Crosslinking and Stabilization
The structure of the capsules is reinforced using crosslinking agents or by adjusting temperature and pH conditions, thereby increasing resistance to premature degradation.
Drying
Once the capsules are formed, they undergo a drying process to remove moisture and ensure the final product’s long-term stability.
Conclusion
Using gelatin for herbicide encapsulation represents a significant innovation in the agricultural sector.
In addition to improving product performance, this technology contributes to lower environmental impact and safer application practices.
As research continues to advance, more applications are expected to transform how agricultural inputs are formulated and used.
