Iranian researchers develop starch nanocrystals to conserve food products

Researchers from the University of Tehran in Iran have developed new starch nanocrystals that can be used as a coating for the protection and enrichment of food products in processing facilities.

Over the past few years, researchers have studied the use of starch for the conservation of food products as it is cheap and biodegradable.

The new research uses this powder to produce a new coating that does not have any undesired effect on the consumer or the environment.

In order to develop the coating, the researchers used date palm pit extract as a source of polyphenol and antioxidant, and placed it inside the nanocrystalline coating of starch.

Food products with phenol play a key role in several metabolism processes in the body, and in the prevention of diseases.

The sizes of nanoparticles before being placed inside the date palm pit extract and nanocapsules (nanoparticles containing date palm pit extract) were 164nm and 198nm in size, respectively.

The nanocrystals that were produced were 48nm in size.

According to the researchers, as the nanocrystals have been prepared through the acidic hydrolysis of starch granule at room temperature, they are resistant to acidic media.

In addition, they are tough, non-permeable, as well as economical as they are made from cheap starch.
