Polysaccharides from instant coffee powder

Arabinogalactan as a potential furfural precursor in roasted coffee

“…Based on these reports and the hydrolysate data from Table 1, we conclude that the major polysaccharides in fraction C1 were mannan and arabinogalactan. Roasting clearly modifies the arabinogalactan, promoting considerable loss of arabinose residues which agrees with data from the literature (Wolfrom & Anderson, 1967). A small % increase observed in the levels of mannose and xylose on roasting appears to reflect changes in the relative proportions of the components as a result of an overall weight loss due to selective loss of arabinose and galactose residues.…”

Antitussive and immunomodulating activities of instant coffee arabinogalactan-protein

“…Partly modified Wolfrom and Anderson procedure used for the isolation afforded AGP as a light grey fluffy material [13,14]. Its sugar analysis revealed the presence of two main sugar components, i.e.…”

“…The arabinogalactan-protein complex (AGP) for biological tests has been isolated from 100% C. arabica freeze-dried instant coffee type according to Wolfrom and Anderson procedure [13] with minor modifications [14].…”

“…However, little attention has been paid to instant coffee AGPs, which were shown to be significantly modified during industrial process. The pioneering work on AGP isolation procedure from instant coffee performed by Wolfrom and Anderson [13] has been re-discussed in term of its structure in our previous works [14][15][16].…”

Chemical and physical properties of an arabinogalactan-peptide from wheat endosperm

“…Arabinogalactans have been isolated from plant tissues ofdiverse origin. They can be readily extracted, usually with water, and have been obtained from coniferous woods (Aspinall, 1959;Timell, 1965), coffee beans (Wolfrom &Patin, 1965;Wolfrom &Anderson, 1967), soya-bean seeds (Morita, 1965a,b;Aspinall et al, 1967a,b), aquatic moss (Geddes & Wilkie, 1971), Saguaro cactus cortex (Steelink et al, 1968), apple fruit (Barrett & Northcote, 1965; Knee, 1973), rapeseed (Siddiqui & Wood, 1972), Siratro leaves (Ford, 1972), broad-bean leaves (Pusztai et al, 1971), and from suspension-cultured cells of tomato and sycamore (Lamport, 1970).…”
