Wrapper Equipped With Preservatives : Researchers at the Institute of Nano Science and Technology (INST), Mohali have developed a composite paper made of graphene oxide. This paper has been equipped with preservatives to prevent spoilage of fruits. According to a report published in Dainik Jagran, the researchers who developed the composite paper say that it can be used as a wrapper to increase the shelf life of fruits.
In the current dipping technique of preserving fruits, the preservatives are absorbed by the fruit, which puts the fruit at risk of becoming toxic. In contrast, the newly developed wrapper releases preservatives only when needed. Another feature of this wrapper is that it is reusable, which is not possible with the currently prevalent technology for fruit preservation.
developed like this
To develop this non-toxic and reusable wrapping paper, the researchers incubated the carbon matrix with preservatives (like warming the eggs). After 24 hours of heating at room temperature, the obtained product was washed several times to remove excess preservatives, and finally, this carbon-preservative composite was molded into paper.
Farmers and food industry will benefit
Researchers who developed this paper say that this new product can benefit farmers and the food industry by increasing the shelf life of fruits. He says that the use of the new wrapper has seen an improvement in the phenol content. Phenol is a mildly acidic toxic white crystalline solid derived from coal tar, used in chemical formulations and in dissolved form (under the name carbolic) as a disinfectant.
it was an attempt
Researchers from the Institute of Nano Science and Technology (INST), an autonomous institute affiliated to the Department of Science and Technology, Government of India, led by Dr. This study has been done under the leadership of Vijayakumar. The effort of the researchers was to find an alternative that could be grown from the waste, and so that there is no problem of absorption of preservatives in the fruit.
The production of this graphene fruit wrapper requires only the carbon produced by the heating of the biomass. Dr Vijayakumar has stated that “the carbon material obtained from the waste is known to hold a large amount of organic molecules, and thus preservative-loaded carbon has been prepared, and used in paper for the preservation of fruits. has been molded. Increasing the ability of carbon to hold organic molecules has helped us develop this product.”
Current options may cause problems
Fruits spoil quickly; Therefore, about 50 percent of the fruits produced are wasted, causing huge losses. traditionally; Preservation of fruits depends on the coating of preservatives with resin, wax, or edible polymers, which can cause health problems. Researchers claim that using this wrapper for fruits will ensure that customers get better quality fruits.
