by ADMIN 98 views

Introduction

Gelatin, a protein-rich biopolymer, has been gaining attention as a sustainable alternative to traditional plastics in film making. This study aims to explore the effects of chemical modification on gelatin films using formaldehyde and glutaraldehyde, two commonly used compounds in industry. The resulting gelatin films were evaluated for their physical and mechanical properties, including analysis using Fourier Transform Infra Red Spectroscopy (FTIR), tensile testing, water absorption testing, and surface morphological monitoring using Electron Microscopy (SEM) scanning.

Background and Significance

Gelatin, derived from animal collagen, has been widely used in various applications, including food, pharmaceuticals, and biotechnology. Its biodegradable and non-toxic properties make it an attractive alternative to traditional plastics. However, gelatin films often exhibit poor mechanical properties, limiting their practical applications. The addition of chemical compounds, such as formaldehyde and glutaraldehyde, has been shown to improve the mechanical properties of gelatin films. However, the effects of these compounds on the physical and environmental properties of gelatin films are not well understood.

Materials and Methods

Gelatin films were prepared using a solution casting method, followed by the addition of formaldehyde and glutaraldehyde. The resulting films were then evaluated for their physical and mechanical properties using various techniques, including FTIR, tensile testing, water absorption testing, and SEM scanning.

Results and Discussion

The results showed that the addition of formaldehyde and glutaraldehyde had a significant effect on the physical and mechanical properties of gelatin films. Films modified with glutaraldehyde exhibited higher tensile strength and compactness compared to films modified with formaldehyde. However, the thickness and water absorption ability of films modified with glutaraldehyde were lower than those modified with formaldehyde. This suggests that while glutaraldehyde improves the mechanical properties of gelatin films, it also reduces their ability to absorb water.

Surface morphological testing using SEM revealed that the surface of films modified with formaldehyde and glutaraldehyde was uneven, which may affect their interaction with the environment and their potential use as packaging materials.

Additional Analysis and Explanation

The modification of gelatin with formaldehyde and glutaraldehyde not only focuses on increasing mechanical properties but also considers its impact on the environment. Gelatin, as a biopolymer, has been known as an environmentally friendly alternative compared to petroleum-based plastics. However, with the addition of chemical compounds, it is necessary to do an in-depth evaluation to ensure that the film produced remains safe for food use and does not cause negative effects on human health.

Formaldehyde, although often used in industry, is known as a potentially dangerous compound if exposed in high quantities. Therefore, this research must ensure that the formaldehyde concentration used is safe and in accordance with applicable standards. On the other hand, glutaraldehyde is a substance that also has preservative properties, so that it can have a positive effect in extending the shelf life of the product wrapped using the gelatin film.

Practical Applications

The modified gelatin film can be used in food packaging due to its decoration and harmless nature for the environment. This is very important in the midst of global issues about plastic pollution and environmental pollution. The discovery that glutaraldehyde can improve mechanical properties without sacrificing sustainability into significant added value.

Conclusion

This research opens further opportunities for the exploration of continuous and safe gelatin modification, as well as increasing understanding of the use of biopolymer in the food and packaging industry. Further research is needed to investigate the long-term impact of the use of this Gelatin film and the potential for the development of new products that are more innovative.
