SUPERABSORBENT POLYMER-BASED MOISTURE ABSORBERS FOR FOOD PACKAGING

Abstract

In recent years, there has been an increasing demand for moisture-absorbing materials used in food packaging. This paper presents a novel approach to enhancing food packaging through the incorporation of superabsorbent materials. Moisture control is critical in preserving various food products' quality and shelf life. Traditional packaging methods often fail to adequately address moisture-related issues, leading to spoilage and decreased product integrity. In response, this study explores the utilization of superabsorbent polymers (SAPs) to develop an efficient moisture absorber for food packaging applications. The effectiveness of SAPs in absorbing moisture, as well as their compatibility with different packaging materials, is investigated. Various factors influencing the performance of the moisture absorber, such as polymer composition, particle size, and distribution, are examined. Additionally, the impact of the moisture absorber on food quality and safety is evaluated through storage trials and sensory analysis. The findings suggest that incorporating superabsorbent-based moisture absorbers into food packaging holds significant promise for extending shelf life, reducing waste, and enhancing product quality. This research contributes to advancing sustainable packaging solutions that address critical challenges in the food industry while maintaining consumer satisfaction and safety. To check the moisture, first, we have to prepare samples of different relative humidities (RH) and humidity is checked by a humidity indicator, put the sachets of different amounts of SAP inside the desiccator. The moisture gained with time interval as a value of the result of tests of this project and by FTIR and FE-SEM functional group available and Surface morphology of SAP powder and hydrogel is obtained.
