Influence of environmental temperature during grain filling period on granule size distribution of rice starch and its relation to gelatinization properties. The two components of starch behave differently on canning, with amylose giving an opaque solution that sets to a firm gel on cooling and with amylopectin forming a translucent paste that remains fluid when cooled. (2020). (2017). There must be an adequate supply of liquid for the starch granules to absorb, taking into consideration the type of starch used and any evaporation of the liquid as it is heated.

Acid-hydrolyzed (thinned) starches are obtained by treatment of starch with mineral acids such as hydrochloric or sulfuric acids resulting in depolymerization of the starch polymer. An increase in To, Tp, and Tc was observed in annealed starch. The effect of repeated versus continuous annealing on structural, physicochemical, and digestive properties of potato starch. Gelatinization temperatures were found to be significantly increased with increasing degrees of cross-linking.

Gelatinization is a semi-cooperative or cooperative process in which the starch breaks down in presence of water and heat; first, the amorphous region (amylose) hydrates and swells, straining and tearing away crystalline regions (amylopectin). Beninca, C., Demiate, I. M., Lacerda, L. G., Filho, M. A. S. C., Ionashiro, M., & Schnitzler, E. (2008).

Study on starch-protein interactions and their effects on physicochemical and digestible properties of the blends. TEMPERATURE Gelatinization temperature differs for diff starch acc. The extent of alteration in the starch properties reflects the resistance or the susceptibility of a starch towards different chemical modifications. This is also accompanied by loss of swelling capacity and viscosity. Corn starch exhibited the highest To, Tp, and Tc compared to faba bean and field pea starch, owing to its characteristic compact crystal arrangement of A-type crystalline cereal starch, compared to C-type crystalline pulse starches.

The homogeneous dual modification consists of either physical/physical or chemical/chemical dual modification. Starch and protein from cereals, meat, and other sources play key roles in providing the appropriate textural and rheological characteristics in food items (Jamilah et al., 2009). These disadvantages can be overcome by dual modification. International Journal of Food Properties, 22(1), 11221133. Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. In yet another study conducted, the effect of the dual modification, acid thinning, and succinylation is studied, for possible applications in the food industry. Abba, H., Ibrahim, A., Shallangwa, G.

Effects of dual modification with succinylation and annealing on physicochemical, thermal and morphological properties of corn starch. (2012). Impacts and potential applications: A review of the modification of starches by heat-moisture treatment (HMT). Cross-linking increased To, Tp, Tc, and H, but the extent of increase in To, Tp, and Tc varied with the technique of cross-linking and type of starch. Radiation Physics and Chemistry, 162, 5465. https://doi.org/10.1016/j.foodhyd.2019.01.035. The lower To, Tp, and Tc for native starches indicate low amylopectin contents. Starch and lipids form inclusion complexes or starchlipid complexes either naturally or during repeated heating and cooling, commonly occurring during food processing. However, those treatments can be harmful to the environment (Fan & Picchioni, 2020). A study reported that rice and maize starches displayed gelatinization temperatures ranging between 58.9 and 72.4C (rice) and 64.3 and 77.2C (maize). This was accredited to the fact that HMT causes reorganization of starch chains in a more ordered structure which was disturbed by the application of ultrasound. Dual modification of achira (Canna indica L) starch and the effect on its physicochemical properties for possible food applications. Romn, L., Martnez, M. M., Rosell, C. M., & Gmez, M. (2015).

Pregelatinized starch is used extensively in products such as instant food items for infants, confectionaries, and soups. Further, DSC shows other drawbacks including its destructive nature and the dynamic nature of the technique. These problems can be solved by non-thermal technology. Recent studies have explored the use of HMT starch in food items like pasta and noodles to obtain desirable qualities like good expansion, minimum cooking time, and good tensile strength (Chandla et al., 2017; Kaur & Singh, 2019; Liao et al., 2019; Schafranski et al., 2021). 2023 Springer Nature Switzerland AG. Journal of Agricultural and Food Chemistry, 54(1), 37123716. https://doi.org/10.1002/fsn3.2506, Kaur, M., & Singh, S. (2019). Oxidation of starch alsoleads to increased relative crystallinity compared to its native counterpart andshows an increase in gelatinization temperature. In addition, compared to the complete gelatinization of starch granules . This is highly desirable for food products like sauces, pasta, and noodles that require starch to be heated and shear-stress resistant during processing (Lin et al., 2019). Thermal Analysis of Textiles and Fibers. (2009).

Impact of acid and oxidative modifications, single or dual, of sorghum starch on biodegradable films. Open access funding provided by Manipal Academy of Higher Education, Manipal. Structure, functionality, and digestibility of acetylated hulless barley starch. The most common sources of starch are corn, wheat, rice, sorghum, potato, and barley (Hu et al., 2020). It has been suggested that starch nanocrystals, similarly to nanoclays (which have a platelet morphology as well), create a tortuous diffusion pathway for permeant molecules through the nanocomposite materials, improving their barrier properties (Le Corre et al., 2010 ). This action of gelatinization stresses the crystallites so that they cooperatively melt at a lower temperature. In the food industry, starch is either used in unprocessed native form (extracted from the plant) or in processed/modified form (Mathobo et al., 2021; Ulbrich & Flter, 2019; Wang et al., 2019a, b, c). Gelatinization in C type starch granulesinitiates from B-type polymorphs at the central hilum at a lower temperature due to loose packing and then moves to A-type polymorphs. Another study has reported that large granules are gelatinized first at higher temperatures followed by smaller granules at lower temperatures and a broader gelatinization range (Vermeylen et al., 2005). Since the pursuit of producing better, cheaper, and healthier starch-based food products never stops, further research and multidisciplinary approaches using various techniques including viscometry, microscopy, spectroscopy, X-ray diffraction, and other methods of thermal analysis are used to investigate the altered physicochemical properties of modified starch used in the food industry which can extend more efficient services to the consumers. It also affects the swelling power and freezethaw stability of starches (Abba et al., 2014). (2015). Acetylation increases the solubility of starch in acetone and chloroform in which native starch is sparingly soluble (Abba et al., 2014).

FACTORS THAT AFFECT GELATINIZATION Temperature Acid Fat and proteins Enzymes Sugar Salt Agitation (stirring) THE STARCH GRANULE (AMYLOSE AND AMYLOPECTIN) The starch granule is made up of polysaccharides amylose and amylopectin.

This was explained by depolymerization in the amorphous region of the starch granule and subsequently in the destruction of their destabilizing effect on the crystalline regions, thus resulting in a rise of To, Tp, and Tc (Zhang et al., 2018).
