“…Lim (1991a) reported that the maximum starch yield per trunk is at the “Angau Muda”, stage (flowering stage) and is declining at the “Angau Tua” stage. Pei‐Lang and others (2006) reported that the starch content at the Angau Muda stage ranged between 39% to 41% (dry weight basis). In a similar study, Hamanishi and others (1999) reported the average starch yield per palm at the Angau Muda stage (12 to 12.5 y) to be between 216 to 219 kg.…”

“…As a whole, it may be said that the sago palm appears to accumulate starch in its trunk from the base upward (Lim 1991b; Jong 1995; Pei‐Lang and others 2006). The highest starch content occurs at the flowering stage (Angau Muda), after which the starch content starts to decline.…”

“…Pei‐Lang and others (2006) studied the composition of associated components in palms at different growth stages and reported that the total and insoluble nonstarch polysaccharides decreased as the palms matured into Angau Muda and Angau Tua stages and increased as the palms aged into the late Angau Tua stage. The amount of phenolic compounds was less than 1%, whereas the lignin content ranged from 9% to 22%.…”

The common industrial starches are typically derived from cereals (corn, wheat, rice, sorghum), tubers (potato, sweet potato), roots (cassava), and legumes (mung bean, green pea). Sago (Metroxylon sagu Rottb.) starch is perhaps the only example of commercial starch derived from another source, the stem of palm (sago palm). Sago palm has the ability to thrive in the harsh swampy peat environment of certain areas. It is estimated that there are about 2 million ha of natural sago palm forests and about 0.14 million ha of planted sago palm at present, out of a total swamp area of about 20 million ha in Asia and the Pacific Region, most of which are under-or nonutilized. Growing in a suitable environment with organized farming practices, sago palm could have a yield potential of up to 25 tons of starch per hectare per year. Sago starch yield per unit area could be about 3 to 4 times higher than that of rice, corn, or wheat, and about 17 times higher than that of cassava. Compared to the common industrial starches, however, sago starch has been somewhat neglected and relatively less attention has been devoted to the sago palm and its starch. Nevertheless, a number of studies have been published covering various aspects of sago starch such as molecular structure, physicochemical and functional properties, chemical/physical modifications, and quality issues. This article is intended to piece together the accumulated knowledge and highlight some pertinent information related to sago palm and sago starch studies.

“…Browning is initiated with the disruption of cell due to cutting or bruising and the compartmentalization is lost. The primary phenolic compounds related to browning are DL-epicatechin and D-catechin [8,9]. Pei-Lang et al [9] reported that the content of phenolic compounds in sago pith depends on its growth stages and height; and the amount of phenolic compound extracted is less than 1%.…”

Recovery of catechin and epicatechin from sago waste effluent. Supercritical CO 2 desorption of catechin and epicatechin from activated carbon. Adsorption of catechin and epicatechin in binary system. a r t i c l e i n f o b s t r a c tThe recovery of valuable phenolic compounds (catechin and epicatechin) from sago waste effluent by activated carbon adsorption was studied in this work. Single and binary component of catechin and epicatechin was studied in static mode using synthetic effluent. Langmuir model was applied to evaluate the adsorption equilibrium data in single system. In binary system, the modified extended Langmuir model by inclusion of surface coverage was used to represent the adsorption data. All experimental data were well represented either by Langmuir model or its modified form. For kinetic study, it was found that pseudo-second order model represents the experimental data better than pseudo-first order model. Adsorption study using real sago waste effluent indicated that activated carbon adsorption process is promising for recovery of valuable phenolic compounds. Supercritical CO 2 extraction of phenolic compounds from activated carbon resulted in low recovery. The addition of ethanol as co-solvent significantly enhanced the desorption of catechin and epicatechin from activated carbon.

Sago supplementation for exercise performed in a thermally stressful environment: Rationale, efficacy and opportunity

Sago (Metroxylin sagu), a carbohydrate (CHO) based dietary staple of Southeast Asia is easily digestible and quickly absorbed, and thus has potential to be prescribed as an affordable pre-and post-exercise food in this part of the world. Compared to other CHO staples, research into the physiological response to sago ingestion is sparse, and only a few recent studies have investigated its value before, during, and after exercise. The purpose of this review is to describe the published literature pertaining to sago, particularly as a supplement in the peri-exercise period, and suggest further avenues of research, principally in an environment/climate which would be experienced in Southeast Asia i.e. hot/humid.
