Development of Primary Food Packaging Material Using Saracaasoca Pods

Abstract

Environmental waste problems caused by non-biodegradable petrochemical-based plastic packaging materials as well as the consumer's demand for high quality food products has caused an increasing interest in developing biodegradable packaging materials using parts of plants. Pods of Saracaasoca are flat, woody, leathery, tapered at both ends containing 4-8 seeds in each pod. Saracaasoca pod is reported to contain glycoside, flavonoids, tannins and saponins. The pods were tested and found to have high water holding capacity and low water retention at different temperature conditions making it suitable for developing a stable packaging material. Two stages of pods (green and brown) were analysed for Carbohydrates, Protein, Fat, Mineral, Moisture contents. The pods are found to be rich in fibre content. Compression molding is used to mold the pods and bring it to shape with the help of a suitable adhesive. The developed packaging material is tested for its stability. Texture analysis (firmness), cobb test and bursting strength are done. It is found to be a cost effective and efficient material. Thus, Saracaasoca pods as a primary packaging material will be an efficient replacement for synthetic packaging.
