Volatile Profile of Hydrosol Extracted from Pistacia vera Soft Bark and Potential Use in Fish Feed Industry

Abstract

The study aimed to evaluate the effectiveness of hydrosol obtained from discarded soft shells of Pistacia vera, which is a byproduct of Pistachio production. The study sought to examine the qualitative makeup of the volatile components found in the hydrosol and assess its potential as an additive in fish feed. To accomplish this goal, a hydrodistillation procedure was used to extract 1 kilogram of soft P. vera peel. The hydrosol achieved a performance level of 170 milliliters per kilogram. The product was analyzed using gas chromatography-mass spectrometry, which identified 16 components comprising 93.37% of the product. The main component of the product was identified as Limonene-4-ol, making up 44.60% of the product. Furthermore, the product contained substantial amounts of Benzenemethanol, alpha. alpha.,4-trimethyl, α-terpineol, Bornyl acetate, Carvone, and Eucalyptol (1,8 cineol). Previous research on the bioactive chemicals found in P. vera softshell suggests that the hydrosol generated from it could be used as a fish feed additive. This is mostly due to its antibacterial and antioxidant effects.
