Pomegranate: The pomegranate (Punica granatum, Punicaceae) is an attractive tree that grows up to 5 m in height. It has glossy, leathery leaves and bears showy red flowers at the branch tips. The distinctive shape of the spherical fruit (2.5 to 5 inches in diameter) is imparted by the prominent fleshy red calyx which persists after flowering. The fruit has a tough leathery skin that is variously referred to as the rind, husk, or pericarp. The interior of the fruit is compartmentalized by membranous walls (carpels) and white spongy pith. The resulting locules are packed with 600 to 800 sacs or arils, each of which contains one seed and juicy pulp. Conventional pomegranate juices normally constitute 45 to 65% of the whole fruit. The 50% edible portion (the arils) consists of approximately 80% juice pulp and 20% seeds; traditionally the entire aril is crushed to make the juice so the expressed juice contains liquid from the seeds and the surrounding aril juice.4,5 The POM Wonderful proprietary process does not crush the seed and hence POM Wonderful PJ does not contain any seed constituents.
POM Wonderful Pomegranate Juice: POM Wonderful PJ is made from whole California-grown Wonderful variety pomegranates. The Wonderful cultivar bears large purplish-red fruit with a medium thick, tough rind and a very juicy, deep crimson flesh with a tangy flavor. The subsequent cloudy juice is filtered and/or enzyme treated before concentrating to 65 Brix for future 16 Brix juice productions, which are flash pasteurized (Brix is a measurement of the mass ratio of dissolved solids to water in a liquid [e.g. fruit juice, wine]). Based on cumulative data from 2002 through 2007, POM Wonderful PJ contains between 2,400 to 4,000 mg/liter (ppm) GAE (gallic acid equivalent) polyphenols.6 The 2005 through 2007 harvests were consistently at the higher end of this range. The polyphenolic component consisted of approximately 80 to 90% ellagitannins and gallotannins, 8 to 15% anthocyanins, and 2 to 5% ellagic acid.6 POM Wonderful markets a line of 100% natural pomegranate-based juices launched in 2002, which are sold under the same brand name and are available on a year-round basis in the United States, Canada, and the United Kingdom.
