Study on peel components and juice quality of three mandarin hybrids (Citrus reticulata) on sour orange rootstock cultivated in Ramsar, Iran

Abstract

The peel components and juice quality of three mandarin hybrids were investigated in this study. Peel components were extracted using the cold-press method and analyzed using GC-FID and GC-MS. Total soluble solids, total acid, pH value, ascorbic acid as well as density were determined in juice obtained from mandarin hybrids. Twenty-six, thirty-five and nineteen peel components were identified in Fortune, Robinson and Osceola respectively including: aldehydes, alcohols, esters, monoterpenes, sesquiterpenes and other components. The major components were limonene, γ-terpinene, (E)-β-ocimene, β-myrcene, sabinene, linalool and α-Pinene. Among the three scions examined, Fortune showed the highest content of aldehydes and Robinson showed the highest content of TSS. This study shows that scion has a profound influence on aldehyd and TSS that are important to quality improvement.
