study of the potential of by-products from pineapple processing in Thailand

Abstract

The data, focusing on the supply of pineapple for industrial processing in Thailand during the period from 2011-2020, was acquired. The data indicated that productivity had tended to decrease during the period between 2011-2015 due to phenomena of drought and a reduction in prices, while increasing trends were observed during the years between 2016 - 2019. In the year 2020, Thailand was the biggest exporter of canned pineapple in the world, and the export value was approximately 345 million U.S. dollars. During the process, the generated by-products were peels, cores, stems, and crowns at approximately 35.5, 14.7, 4.6, and 4.3%, respectively. Based on the annual production of 1,689,884 tons, the total by-products from pineapple processing would generate 993,402.4 tons, which could be divided into peels, cores, stems, and crowns at 596,713.8, 247,089.9, 773,20.7, and 722,78.0 tons, respectively. Valorization of by-product for health applications such as pharmaceutical, cosmetic, and health food has been reviewed.

The Chemical Characteristics and In Vitro Degradability of Pineapple By-Products as Potential Feed for Ruminants

“…In our study, the amounts of pineapple by-products obtained after fruit processing nearly double those (skin, shoot tip, core, stems, crowns) reported by other investigations [8,14], except for the peel. In terms of chemical composition, in other studies on pineapple by-products [8,13,14,19,23], it is reported that CP, EE, NDF, and ADL range from 4.4-5.7, 0.2-1.2, 20.5-44.69, and 23.04-39.40% DM, respectively. The same references also quantified organic matter (OM), non-fiber carbohydrate (NSC), and water-soluble carbohydrate (WSC), resulting, respectively, in 95.54, 48.8, and 5.4% DM.…”

“…These products are known to be rich in many nutrients, such as vitamins (i.e., A, C, B 1 , B 6 , folic acid, betacarotene), minerals (i.e., copper, manganese), and other compounds with antioxidant, digestive (bromelain), anti-inflammatory, and analgesic properties [5,6]. During fruit processing, a large quantity (about 65%) of leftovers is discarded as waste, including the peel (35.5%), core (14.7%), pomace (6.0%), bud end (4.6%), and crown (4.3%) [7,8]. Concerning the amount of fruit produced worldwide, more than 18 million tons of pineapple leftovers are generated annually.…”

First Report of Colletotrichum fructicola Causing Fruit Rot and Leaf-Tip Dieback on Pineapple in Northern Thailand

“…Thailand is currently the second-largest supplier of processed pineapple fruit in the world. Production areas for pineapple in Thailand have been divided into northern, northeastern, central, and southern parts [ 12 ]. Most cultivated areas are in Prachuap Khiri Khan, Rayong, Ratchaburi, and Chonburi provinces [ 11 ].…”
