Physicochemical properties and textile utilization of low- and moderate-substituted carboxymethyl rice starches with various amylose content

Aplikasi Campuran Alginat Dari Sargassum Crassifolium Dan Gum Sebagai Pengental Textile Printing

“…Adanya kelemahan penggunaan alginat sebagai pengental pada textile printing karena viskositasnya yang rendah, stabilitasnya yang kurang baik maupun kecenderungan terjadinya pengendapan pada larutan dengan kandungan ion yang tinggi, medorong beberapa peneliti mencoba mencari alternatif pengental dari pati atau selulosa yang termodifikasi (Abdel-Halim et al, 2008;Tatongjai & Lumdubwong, 2010;Zhang et al, 2012), melakukan formulasi dari pengental sintetik (Ibrahim et al, 1994), menggunakan aplikasi surfactan (Fijan et al, 2007) atau mendaur ulang pengental yang sudah dipakai (Fijan et al, 2009). Gum sendiri seperti guar gum juga memiliki potensi digunakan sebagai pengental pada textile printing (Turk & Schneider 1998).…”

Recent advances of starch-based excipients used in extended-release tablets: a review

“…Substituted starches are prepared by esterifying and etherifying the hydroxyl groups of glucose units, such as acetylated starch (Ali & Hasnain, 2011;Han et al, 2012), carboxymethyl starch (CMS) (Tatongjai & Lumdubwong, 2010;Bhandari & Hanna, 2011), hydroxyethyl starch (Liu et al, 2003), hydroxypropylated starch (Chuenkamol et al, 2007) and phosphate starch (Park et al, 2004). The substituted starches are prepared in aqueous, organic or water-miscible organic media.…”

“…The properties of CMS excipients and the drug release mechanisms concerning monolithic tablets have been frequently referred. Numerous researchers have investigated the influences of the percentage of protonation, the degree of substitution (DS) (Figure 1) and amylose content on the release kinetics of small bioactive agents from CMS matrix tablets (Table 1) (Lemieux et al, 2009;Tatongjai & Lumdubwong, 2010;Assaad et al, 2011).…”

“…(Wierik et al, 1997a) Carboxymethyl starch Amylose content; protonation ratio (PR); degree of substitution (DS). (Tatongjai & Lumdubwong, 2010, Assaad & Mateescu, 2010, Lemieux et al, 2009 A pH sensitive hydrophilic matrix; lower pH inducing a fast swelling; stable gellayer formed at the presence of Na + ion. (Lemieux et al, 2009) A sustained release property (DS 0.1-0.2); a delayed release property (DS 0.9-1.2).…”

Effect of Agitation in Alkalization Process on the Characteristics of Sodium Carboxymethyl Sago and Cassava Starches

“…The carboxymethylation process takes place by substituting the native starch hydroxyl group (-OH) with the carboxymethyl group (CH2COO-) to produce Na-carboxymethyl or carboxymethyl starch (CMS) [3]. The utilization of Na-carboxymethyl starch is used as a disintegrant in the pharmaceutical industry [4] as well as sizing and printing agent in the textile industry [5][6].…”
