“…These studies correspond with the study conducted by [29] which referred to the superiority of chitosan nanoparticles comparing with normal chitosan in the same concentrations in inhibiting A. flavus. This superiority occurs due to the change in physical, chemical and vital characteristics for chitosan, as chitosan nanoparticles possesses the unique characteristics in which nanoparticles features such as small size, bigger surface area, surface charge, ability to accumulate in the target area and cell membrane [30].…”

Chitosan nanoparticles have been prepared from the stalks of Agaricus bisporus mushroom via ionic gelation according to the connection between positive chitosan and negative tripolyphosphate (TPP). chitosan nanoparticles diagnosed via Fourier Transform Infrared (FTIR); the size and shape of chitosan nanoparticles are tested by Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM). chitosan nanoparticles have been tested in inhibiting Aspergillus flavus in the concentrations (0.5, 1, 1.5, 2) %. The chitosan nanoparticles inhibition rate of the fungus has reached (35, 100, 100, 100) % respectively. tested The effectiveness chitosan nanoparticles in preventing A. flavus from producing Aflatoxin B1 in the concentrations (0.5, 1, 1.5) %. The rate of Aflatoxin B1 production inhibition by chitosan nanoparticles has reached (75.7, 100, 100) % respectively after 21 days of incubation at 28 degrees after estimating Aflatoxin B1 via HPLC. The study has proven that the effectiveness of chitosan nanoparticles in inhibiting the growth of A. flavus and inhibiting the production of Aflatoxin B1 from the fungus.

Chitosan is a biopolymer obtained from chitin, one of the most abundant and renewable material on Earth. Chitin is a primary component of cell walls in fungi, the exoskeletons of arthropods, such as crustaceans, e.g. crabs, lobsters and shrimps, and insects, the radulae of molluscs, cephalopod beaks, and the scales of fish and lissamphibians. The discovery of chitin in 1811 is attributed to Henri Braconnot while the history of chitosan dates back to 1859 with the work of Charles Rouget. The name of chitosan was, however, introduced in 1894 by Felix Hoppe-Seyler. Because of its particular macromolecular structure, biocompatibility, biodegradability and other intrinsic functional properties, chitosan has attracted major scientific and industrial interests from the late 1970s. Chitosan and its derivatives have practical applications in food industry, agriculture, pharmacy, medicine, cosmetology, textile and paper industries, and chemistry. In the last two decades, chitosan has also received much attention in numerous other fields such as dentistry, ophthalmology, biomedicine and bio-imaging, hygiene and personal care, veterinary medicine, packaging industry, agrochemistry, aquaculture, functional textiles and cosmetotextiles, catalysis, chromatography, beverage industry, photography, wastewater treatment and sludge dewatering, and biotechnology. Nutraceuticals and cosmeceuticals are actually growing markets, and therapeutic and biomedical products should be the next markets in the development of chitosan. Chitosan is also the object of numerous fundamental studies. An indication of the widespread exploitation and constantly growing importance of this biopolymer is the total of over 58,625 scientific articles published between 2000 and 2017. In this chapter, after a description of chitosan fundamentals, we highlight selected works on chitosan applications published over the last two decades.
