ABSTRACT

 

In India, the leaves of various trees such as Banana, Jackfruit, Banyan and Palash (Butea monosperma) have been used traditionally for eating of food on the top of it. These leaves provide not only the support to hold food ingredients but also shown health benefits by providing nutrients and antioxidants like polyphenols when food is served on it. The modern life style of using disposable dishware made up of plastic and other synthetic materials which are non biodegradable have raised the concern towards the health and to the environment. In this regard, the present work, emphasize the use of food grade waste leaves and binder to make disposable dishware by heat moulding. For the type I of dishware the biodegradable and food grade material, Butea monosperma leaves (local name used Palash leaf) and fine wheat powder cooked in water termed as Maida gum is used as binder are used as natural source for the economic production of dishware to eat food. The leaves of Palash were collected, washed and dried under sun and used in another type II the leaves of Teak and Palash as well as Bagasse (the sugar cane residue after extraction of juice) were ground to powder after washing and drying. The Maida gum was used as binder. The disposable dishware prepared by both methods was evaluated for various properties like rigidity, durability and temperature resistance, food grade test and biodegradability. The addition of the paper base stuck to the leaf increased the strength of the disposable dishware and gave rigidity and proper shape to the disposable dishware. The hydrophobic nature of the leaf that was stuck to the paper base did not allow food to absorb to the disposable dishware. The disposable dishware is durable for single use and could resist the temperature of the hot and frozen food. The dishware prepared by type II using leaf powder, soaked news paper paste are very strong, can withstand boiling high and frozen cold temperature, unbreakable, rigid and could be mould to any shape and size. The added advantage is that the dishware prepared by both methods is biodegradable and can be composed to fertilizer for plants creating no waste.
