The strong demand for biological materials in the food industry places chitosan at the forefront of other biopolymers. The present study aims to evaluate the antifungal properties of chitosan extracted from shrimp shell waste (Parapenaeus longirostris) against post-harvest strawberry (Fragaria × ananassa) spoilage fungi. The physicochemical charact...

For many years, chitosan has been widely regarded as a promising eco-friendly polymer thanks to its renewability, biocompatibility, biodegradability, non-toxicity, and ease of modification, giving it enormous potential for future development. As a cationic polysaccharide, chitosan exhibits specific physicochemical, biological, and mechanical proper...

The present invention aims to develop a process for the biological and ecological extraction of chitosan from shrimp shells. The idea revolves around biological extraction using natural products that do not harm the environment, reduce production costs, and increase the bioavailability of biological activities, in particular antimicrobial and antio...

The present invention aims to prolong the post-harvest shelf life of strawberries and similar fruits. The idea revolves around biological treatment using natural products that are not harmful to the environment. The invention involves chitosan extracted with citric acid and calcined plant ash, then solubilized in acetic acid to protect the cellular...

Fungal pathogens are one of the main causes of strawberry’s post-harvest losses. This is currently prompting producers to overcome this problem by using natural ingredients that meet food safety standards. The present study highlights the chitosan effect on fungal strain’s growth responsible for strawberry fruit post-harvest losses. Chitosan was ex...

The climatic conditions of the growing regions influence the fruit’s microbiological quality and their tolerance to post-harvest pathogens. The present work aims to identify the prevalence of bacterial and fungal strains of strawberries (Fragaria × ananassa) in the Gharb and Loukkos regions of Morocco. Thus, to establish a correlation between the m...

The current study aims to develop eco-friendly and economical chitosans with a wide range of applications using organic acids for shrimp shells demineralization. Chitosan samples were extracted from shrimp (Parapenaeus longirostris) shells and the demineralization step was performed with three organic acids (citric, acetic, and lactic) and two mine...

Developing bioactive food packaging, capable of extending the shelf life of fruits, has received increasing attention in recent years. The present study highlights the interest in post-harvest treatment for strawberries with chitosan as a preservation solution. Chitosan extraction was carried out from shrimp shells (Parapenaeus longirostris), compo...
