Strengthening Property of Glucose Links in Protein Films

Abstract

INTRODUCTION

The use of plastics as a form of packaging has surged with the aftermath of the Industrial age. It is known for its durability under pressure. Other qualities include its barrier against moisture and liquids. However, despite all its positive attributes, plastics are non-biodegradable, which is a problem against the rising concerns for the environment. In response to these concerns, the researcher attempted to develop a biodegradable plastic film derived from a protein based gelatin. Individually, the protein film is weak under stress. Nevertheless, it is theorized that the addition of glucose during the formation of the protein film strengthens the structure of the product by acting as molecular scaffolding.

METHODS

The researchers used experimental method in this study. An experiment was conducted with a control group and four other groups with differing amounts of glucose. The product's tensile strength was determined by setting the product on an axis and putting different but continuous amount of weight. The instance where the product begins to show signs of irreversible deformation and fracturing into multiple pieces is noted. The obtained raw data is subjected under a Pearson test of significance in order to show the significant relationship between the amount of glucose and the resulting tensile strength for each trial.

RESULTS

The experiment resulted in 80.02% relationship between the amount of glucose and the pressure range before the product experiences irreversible deformation and 93.17% before the fracture point. At α = .01, this relationship is significant. For a more specific relationship, there is an increase of 200% in endurable stress with every 5 grams of glucose added to the protein film and a similar increase in the fracture point. It can also be noted that the amount of glucose roofs at 35 grams before the product becomes brittle and the tensile strength formula becomes unusable. In conclusion, the addition of glucose in protein films strengthens its tensile strength.

DISCUSSIONS

The material can be utilized for single-use plastics that are designed to break down after use. The material procured from this experiment, however is deficient in other qualities of packaging such as; thermal and static insulation, and decrease of biodegradability. Researchers recommended that future replications utilize the readiness of carbohydrate polymers to bond with R-groups, which can change the whole property of the product.
