Abstract :
Pistachios are one of the most important agricultural products in Iran and play an important role in the country's exports. Agricultural by-products are destroyed in different stages without being processed, and transformation industries in Iran do not take full advantage of all the components of an agricultural product. Chemical and mineral compounds are compounds that are either produced in the organs of different plants or absorbed by the plant from the environment. Pistachio shell is the main part of pistachio by-products. The presence of these compounds in pistachio leaves and skins can be used as a source for human use in industry and agriculture. In this research, the detection and measurement of organic and mineral substances in pistachio soft skins, which are produced in pistachio collection centers along with pistachio processing, and it was concluded that these substances are mostly considered as waste and waste, they can be used The identification of these substances was done with the help of usual laboratory methods and also with GC-MS method. The primary organic materials in pistachio skin include various types, about fifty percent of these materials are structural organic materials such as cellulose and pectin. Types of proteins and amino acids that are nitrogen-containing molecules. They make up about 11-15% of the volume of available materials. The share of fats is between 5 and 7 percent, and raw ash, which contains various elements, constitutes 10 percent.
