“…Adeil Pietranera and Narvaiz (2001) evaluated the viscosity of corn and cassava starches along with other technological properties of agar-agar and kappa-carrageenan to look for the possible efficacy of employing gamma irradiation (0 and 2 kGy) as a microbial decontaminating treatment. Their results revealed a decrease in the starch viscosity after irradiation along with a significant loss in the viscosity of puddings prepared from irradiated starches.…”

It is envisaged that there will be a considerable demand in the near future for modified starches. To meet the demand, the chemical modification of starch, including cross-linking, has been widely used to obtain desirable traits that are suitable for various food applications. Radiation processing, being a physical process, is an environmentally friendly alternative to chemical modification. It is economically viable, safe, and possesses several advantages over other conventional methods employed for modification and cross-linking. Irradiation of starch leads to the attainment of such desired functional attributes as reduction of viscosity, high water solubility, and others. This review provides insight into the impact of gamma, electron beam, and ultraviolet irradiation on the physicochemical and functional properties of starch. It also highlights the importance and the exciting new opportunities afforded by radiation treatments as a physical means for the modification of starch.

“…It is well known that KC degrades very rapidly with irradiation. 18,23 FTIR spectra of PVP/KC blends, having no change upon 25-kGy irradiation, also indicated that the leakage of KC is inhibited by blending with PVP. Grafting of KC to PVP or forming IPN diminished the degradation of KC; or PVP preserved the KC against ␥-irradiation.…”

Poly(N-vinyl-2-pyrrolidone)--carrageenan hydrogels (PVP-KC) were prepared by irradiating the mixtures of aqueous solutions of PVP, KC, potassium chloride, and poly(ethylene glycol) by ␥-rays at different doses. Their preliminary laboratory tests were evaluated to identify their usability in wound dressing applications. For investigation of the effect of components on the gelation of PVP, sol-gel analyses were made and gel fractions of the hydrogels were determined. Mechanical experiments were conducted for both unirradiated and irradiated samples. For investigation of the fluid uptake capacity of the hydrogels, swelling experiments were performed in pseudo-extracellular fluid solution at various temperatures. Acidity/alkalinity (pH) and electrical conductivity tests were achieved from aqueous extracts of hydrogels, and bioadhesion strength of the hydrogels was investigated on human skin.

“…Recently, information regarding starch treatment with electron beam (e-beam) in different irradiation dose range, either at low or relative high doses (0 -25 kGy) (De Kerf et al, 2001;Pimpa et al, 2007) or at very high doses (> 50 kGy) (Kamal et al, 2007;Shishonok et al, 2007) were reported. The studies concerning the effects of ionizing radiation were performed on starches extracted from various vegetal sources such as corn (Kang et al, 1999;De Kerf et al, 2001;Adeil Pietranera & Narvaiz, 2001), wheat (MacArthur & D'Appolonia, 1984;Koksel et al, 1996), potato (Ezekiel et al, 2007;Shishonok et al, 2007), barley endosperms (Faust & Massey Jr., 1966), rice (Wu et al, 2002;Bao et al, 2005) or sago (Pimpa et al, 2007). The reported data showed that ionizing radiation treatment generates free radicals on starch molecules that can alter their size and structure (Raffi et al, 1980;Ciesla et al, 1991;Grant & D' Appolonia, 1991;Sabularse et al, 1991;Sokhey et.…”

“…Therefore, the hydrolyze of the chemical bonds occurs by cleavage of starch macromolecule into lower fragments of dextrin, which can be either electrically charged or uncharged as free radicals (Kang et al, 1999). This type of treatment may change the functional and physicochemical properties of starch leading to the increase of solubility (Bao & Corke, 2002), the reduction of swelling power (MacArthur & D'Appolonia, 1984) as well as the reduction of relative viscosity of starch paste (Adeil Pietranera & Narvaiz, 2001) as a function of the irradiation dose. The use of radioisotopic sources ( 60 Co or 137 Cs) handling sources with continuous emission of radiation involves an additional risk of radiological accident compared to the usage of charged particle accelerators which send out radiation only during the technological process and, nowadays, are preferred for applications because they do not provide any risk of radioactive contamination.…”
