Abstract

Abstract: Nowadays, biodegradable protein‐based matrices capable of storing micronutrients and releasing them in a controlled manner are being studied in order to avoid an excessive use of fertilizers. One of the methods to add micronutrients into matrices is through an immersion stage in a saturated solution, which provides matrices with high superficial content of zinc but no incorporation of this element inside the matrix. This is due to the growth of an external layer that keeps the ions from entering the structure. In this study, the plasticizer was modified with the aim of creating more free space to help the ions penetrate the matrices. Thus, the water incorporation generated more rigid matrices with less micronutrient incorporation but with a more homogeneous distribution of the micronutrient (Zn) within it, being more suitable for its controlled release.
