Currently, citrus juice processors convert these residues to low-value animal feed ( 8) through the most energy-intensive operation of the juice-processing plant ( 9). When grapefruit is processed into juice, 51% of the fruit is left behind in the form of rind (peel), rag, seeds, and membranes ( 7). Grapefruit is typically processed into juice but can also be converted into segments and salads ( 1, 4– 6). Red grapefruit varieties dominate, and up to 61% of the cultivated grapefruit was processed ( 1– 3). Of the phenolics and flavonoids analyzed in this study, narirutin and naringin were extracted in the amounts of up to 10,000 and 67,000 μg g −1, respectively.įlorida, Texas, and California are the major producers of grapefruit ( Citrus paradisi Macfad.) in the United States, where approximately 256,000 metric tons were collectively cultivated during the 2018–19 season ( 1). The recovery of pectin, as determined by galacturonic acid content, was between 2.06 and 2.72 g 100 g −1. Up to 97% of grapefruit juice oils and peel oils could be volatilized and contained 87–94% d-limonene. In this study, pectic hydrocolloids, sugars, volatiles, phenolics, and flavonoids were extracted from Star Ruby, Rio Red, and Ruby Red GP and WG using a continuous pilot scale steam explosion system. If individual chemical components found within these side streams could be recovered as high-value coproducts, this would improve the overall value of the grapefruit crop.
