Obtaining polysaccharides-silver nanoparticles composite film for preserving fruits and vegetables, involves heating Ocimum in water, and then foltering obtained Ocimum extract through filter paper

NOVELTY – Obtaining polysaccharides-silver nanoparticles composite film involves heating 20g Ocimum in 100ml water at 100 degrees C for 5-15 minutes, preferably 5 minutes, and then foltering obtained Ocimum extract through filter paper. The filtrate is cooled, and then silver nitrate solution is added to cooled filtrate. The mixture is incubated at 25 degrees C for 1-6 hours, preferably for 2 hours. Polysaccharide powder and glycerol are added to incubated mixture, and then processed to obtain the finished product. USE – Method for obtaining polysaccharides-silver nanoparticles composite film for preserving fruits and vegetables (all claimed). ADVANTAGE – The method enables to obtain polysaccharides-silver nanoparticles composite film in an efficient manner.

Main Application Field

A11 (Polysaccharides; natural rubber; other natural polymers (only a restricted range of (modified) natural polymers are included. Thus starch would be excluded, but chemically modified starch included).); A88 (Mechanical engineering and tools e.g. valves, gears and conveyor belts.)
