Thiabendazole and/or orthophenylphenate were used as fungicides. The grapefruit was coated with a food-grade vegetable and or lac-resin-based wax or resin. Rio Red grapefruit from a packing house in Mission, Texas, was also acquired for these experiments. The grapefruit was treated with either thiabendazole, imazalil, fludioxonil, or azoxystrobin and coated with food-grade beeswax or vegetable-based wax. Star Ruby grapefruit from a packing house in Tulare County, California, was acquired for these experiments. This allowed for simulation of steam explosion of packing house fruit that does not meet the stringent standards for fresh market sale and could ultimately be processed for value-added compound extraction. Packing house fruit was prepared for fresh market sale by treatment with fungicides and wax to improve shelf life and appearance and was used as received. Star Ruby, Rio Red, and Ruby Red Grapefruit In this study, we describe the use of a continuous pilot scale steam explosion system as a proof-of-concept study for processing of Star Ruby, Rio Red, and Ruby Red grapefruit from California, Texas, and Florida for the extraction of pectic hydrocolloids, sugars, volatiles, phenolics, and flavonoids. is of the red varieties, the application of steam explosion for the extraction of value-added compounds from whole fruit and juice-processing remnants of red grapefruit was deemed appropriate. Considering that the majority of grapefruit cultivated in the U.S. Therefore, it would be expected that the pectic hydrocolloids, sugars, volatiles, phenolics, and flavonoids that can be extracted using steam explosion of grapefruit will differ from sweet orange fruit. Sweet orange fruit and grapefruit not only differ in color and size but also in the quality and quantity of specific components associated with their composition. This previous study has focused only on the sweet orange varieties used for orange juice processing in Florida. Pectic hydrocolloids, sugars, volatiles, phenolics, and flavonoids have been extracted from orange juice-processing residues previously, using a continuous pilot scale steam explosion system ( 10– 12). To accomplish this, steam explosion was explored as a means of extracting maximum amounts of these high-value compounds. If these compounds could be extracted from the residues, these high-value chemicals could bring new revenue streams to grapefruit processing plants and improve profit margins. However, grapefruit process residues contain valuable pectic hydrocolloids, sugars, volatiles, phenolics, and flavonoids that are lost when the residues are converted to animal feed. The result is little to no-profit margin when energy costs are high. 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). This includes coupons that are downloaded onto your personal MVP Card.Florida, 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).
