Processing of an underutilized fruit crop sumac berry from the north-eastern region of India: A Review

Abstract

Sumac, a native wild fruit crop with over 250 varieties, grows 12-25 feet in sub-tropical to tropical climates with well-drained soil, creamy white blooms, and waxy-coated seeds. R. chinensis Mill. is a promising natural medicine with health benefits, anti-cancer, antiinflammatory, antimicrobial, antiviral, and antidiarrheal properties. Its methanolic extract has reduced kidney stone risk, suppresses bone resorption, and inhibits HIV-1 activity. Evidence suggests that R. chinensis contains flavonoids, phenolics, and triterpenoids because of its excellent nutritional profile, and distinctive tangy flavor, Rhus chinensis has enormous potential as a niche fruit crop. Rhus chinensis Mill. fruits are notably rich in carbohydrates(15.49 ± 1.60%), ascorbic acid (840.45 ± 86.44 μg/g), and minerals like potassium and phosphorus. While the fruit pulp is naturally acidic, processing it into tablets and candies reduces its acidity by 3.70% and 3.68%, enhancing its palatability and potential health benefits. Sumac processing typically adheres to traditional methods, with the berries sun-dried for approximately one week. Additionally, dried fruits, jams, juices, and tea can be made from Rhus chinensis. Some difficulties are raising customer awareness, conquering ignorance about cultivation, and adjusting its flavor to Western palates. Breeding programs, post-harvest technology, marketing, and sustainable farming methods are needed to overcome these obstacles.
