Arrowroot is a local tuber from Indonesia with a high starch content and potential source as a porous starch (PS) material. However, the utilization of arrowroot starch as PS and optimization of PS production using the Central Composite Design (CCD) has not been explored. This study aims to optimize the incubation time (3, 6, and 9 h) and enzyme concentration (50, 100, and 150 U/g) of arrowroot PS production with thermostable α-amylase (AA) by response surface method using the CCD model. The starch suspension (25% w/v) was hydrolyzed with AA at sub-gelatinization temperature (60°C) and the effects of incubation time (3, 6, 8, 10, and 12 h) and enzyme concentration (50, 100, 150, 200, and 300 U/g) on functional characteristics of PS (Water (WAC) and Oil Absorption Capacity (OAC)) were determined to obtain near optimal value for further optimization in CCD. The result concludes and validate that the optimum condition of 5.24 h incubation time and 107.86 U/g AA concentration may achieve maximum WAC and OAC of 96.67% and 103,06%. The optimal PS also showed an improved AR (25.01%), high solubility (88.92%), and lower amylose content (36.56%) against non-modified starch. SEM result confirms porous structure. FTIR data shows increase in intensities and no alterations in functional groups. XRD data reports changes of crystalline type of CA to A, and a decrease in relative crystalline value. These data demonstrate that arrowroot can be used as an alternative economical local source in porous starch production for adsorbent application in various fields.

“…The functional groups present in the PSA/OMMT composite and its precursor are shown in Figure 3. The PSA spectrum contains a broad peak at around 3408 cm −1 corresponding to the hydroxyl stretching vibration in the polysaccharide chain [36], 2 narrow peaks at 2925 and 1639 cm −1 attributed, respectively, to the C-H stretching of the CH 2 groups in the amylose/amylopectin-rich polymer and the adsorbed water [23], and 3 further peaks at 1156, 1028, and 928 cm −1 that can be associated with the C-O, and C-O-C stretching vibrations in the α-1,4 glycosidic linkage [36]. The characteristic absorption bands for Ca-MMT clay appear at about 3627, 3417, 1642, 1042, 532, and 460 cm −1 , whereas, for OMMT bands appear at 3627, 3417, 2919, 2848, 1642, 1516, 1467, 1042, 532, and 460 cm −1 .…”

Effective Removal of Methyl Orange Dyes Using an Adsorbent Prepared from Porous Starch Aerogel and Organoclay

et al. 2023

Intending to provide efficient and compact wastewater remediation, the present work is exploiting and introducing a novel composite prepared from porous starch aerogel (PSA) and organically modified Ca-montmorillonite (OMMT) for the removal of dyes from aqueous samples. First, potato starch components were used as a hydrolysis precursor to obtain PSA. The organoclay samples were prepared by co-intercalation of octadecylamine (ODA) into Ca-MMT using a low-temperature melting procedure. Composites with different starch-to-organoclay ratios of 10:1, 1:1, and 1:10 were then prepared by a blending process in distilled water and used for methyl orange (MO) uptake. The removal of methyl orange dyes increased with the amount of organoclay in the PSA matrix. Characterization revealed that organoclay synergy improved the PSA surface chemistry, while an important improvement in textural properties and thermal stability was also observed. The composite’s efficiency was demonstrated by high removal capabilities towards MO in most experimental runs, with a maximum adsorption capacity beyond 344.7 mg/g. The fitting result showed that MO adsorption follows a monolayer adsorption model, and chemisorption was the rate-controlling step. Nonetheless, this study proved the great potential of PSA/OMMT in dyeing wastewater treatment. Furthermore, starch modification is proven as an effective approach to enhancing the performance of starch-derived adsorbents.
