A master’s thesis at the College of Agriculture at the University of Basrah discussed (the effect of chitosan polymer immersion and the type of packaging on the storage capacity and quality of Sidr fruits, the red Malasi variety, and the extraction of some active substances from them) The message of the researcher (Abrar Sabah Jassim) included Using three concentrations of chitosan (2,1,0)% and using three vacuum packages, plastic and cardboard boxes, then stored at 4 °C for 8 weeks. The aim of the thesis is to improve the storage capacity of the red molasses Sidr fruits, urging the effect of the factors used in the study The thesis concluded that the response of immersion with chitosan polymer at a concentration of 2% improved most of the chemical, physical and qualitative characteristics of the fruits. The packing with airless polyethylene bags also preserved the fruits compared to the other package The thesis recommended the use of chitosan immersion and vacuum packing at 4°C for a period of 6 weeks.
