Insights on the acid hydrolysis of achira (Canna edulis) starch: Crystalline and double-helical structure changes impacting functionality

Evaluating the Effects of Microwave Treatment on Functional and Physicochemical Properties of Different Edible Seed Flours

“…The CI is defined as the degree of crystallinity in the samples and is considered as a crucial qualitative indicator. The CI was calculated by dividing the area under the crystalline peaks by the total area under the diffractogram . As mentioned in Table , the CI of untreated samples was estimated to be 41.53, 35.60, 44.36, 38.53, 41.58, and 40.81% in the case of FS, BS, NS, NGS, CS, and FGS flours, respectively.…”

“…The CI was calculated by dividing the area under the crystalline peaks by the total area under the diffractogram. 27 As mentioned in Table 3, the CI of untreated samples was estimated to be 41.53, 35.60, 44.36, 38.53, 41.58, and 40.81% in the case of FS, BS, NS, NGS, CS, and FGS flours, respectively. MT is known to induce changes in seed flour by altering the overall crystallinity of the samples.…”

“…Diffractograms were further analyzed to determine the area of crystalline peaks as well as amorphous peaks. Accordingly, the crystallinity index was determined using eq normalC normalr normaly normals normalt normala normall normall normali normaln normali normalt normaly normali normaln normald normale normalx ( % ) = A normalc false( A c + A a false) × 100 where A c is the area of crystalline peaks and A a is the area of amorphous peaks.…”

“…Structural heterogeneity often arises due to the formation of different starch crystals through association with retrograded amylose as well as amylose−lipid complexes. 27 Moreover, enhanced ΔT r is also influenced by changes in transition temperatures induced by MT. This is primarily due to alterations within the polysaccharides.…”

Industrial processes for the valorization of medical waste fractions

“…The size of crystallites was 10-50 nm using XRD data, and the typical particle size was 221 nm, via PSD analysis.Nevertheless, there are still many other applications found in modern use of acid hydrolysis as a pretreatment Liu et al (2022),. established a kinetic model of biomass-derived disaccharide hydrolysis over solid acid: A case study on hierarchically porous niobium phosphate Mendez-Montealvo et al (2022),. examined how long-term acid hydrolysis affect the progression of the crystalline and double-helical form shifts on achira starch.…”
