Physicochemical properties of pectins from ambarella peels (Spondias cytherea) obtained using different extraction conditions

Characterization of Jackfruit (Artocarpus Heterophyllus) Waste Pectin as Influenced by Various Extraction Conditions

“…Different factors, mainly extraction temperature, pH, time and solubilizing agents affect the extraction of pectin (Yeoh et al, 2008;Kertesz, 1951). Previous studies also revealed higher extraction yield by sodium hexametaphosphate and ammonium oxalate than simple acid hydrolysis (Nazaruddin et al, 2013;Ismail et al, 2012;Koubala et al, 2008b andMohamed andHasan, 1995). In the middle lamella of plant cells, pectins are physically bound in situ via metallic cations, especially divalent cations.…”

Pectina: da matéria-prima ao produto final

“…Novas fontes potenciais permanecem não usuais em função de certas propriedades estruturais indesejáveis [3,39] . Dentre as matérias-primas alternativas estudadas para extração de substâncias pécticas podem ser citadas: os frutos de Chaemomeles japonica ou marmelo do Japão [39] , as folhas do Krueo Ma Noy, uma planta trepadeira nativa da Tailândia [40,41] , o pericarpo de ambarela (fruta nativa da Polinésia) [42] , a casca de manga [43,[44][45] , o repolho [46] , as cascas de banana [47] , o resíduo de cacau [48] e a casca de maracujá [49][50][51][52][53][54] . Na Tabela 1, podem ser encontrados os teores aproximados de pectina em diferentes fontes vegetais [55,56] .…”

Environmentally friendly preparation of pectins from agricultural byproducts and their structural/rheological characterization

“…Pectins are industrially obtained from apple pomace and citrus peels in a chemical way with strong acids such as oxalic (Koubala et al, 2008), hydrochloric (Choi, 1996;Hwang et al, 1998), nitric (Constenla et al, 2002), and sulphuric acids (Garna et al, 2007) which are regarded as conventional acid extraction (Yapo, 2009). Even though these chemical procedures have advantages from an efficient and economical point of view, they may cause environmental problems by producing hazardous contaminants that must be treated.…”
