“…Similar results were shown to be represented with arrowroot and yam starch whereas for potato and corn starch the absorbance intensity was increased gradually after the treatment ( Fig. 4 ) ( Teixeira et al, 2018 ). It can be concluded that most of the starch possess similar chemical composition but not the same concentration as it varies from species to species.…”

“…Similar results were exhibited by gamma-irradiated lentil, kithul, cassava starch but potato starch mostly shows increased crystallinity as it possesses B-type crystallinity comprising 30–44 glucose units whereas A-type possess 23–29 glucose units making B-type more resistant to gamma rays ( Fig. 3 ) ( Majeed et al, 2017 ; Sudheesh et al, 2019 ; Teixeira et al, 2018 ). Based on these studies, it can be stated that starch possessing A-type and C-type crystallinity with core comprising of A-type crystallinity is more sensitive to gamma rays compared to the B-type that appear more resistant ( Table 1 ).…”

Starch is one of the most common and abundantly found carbohydrates in cereals, roots, legumes, and some fruits. It is a tasteless, colorless, and odorless source of energy that is present in the amyloplasts of plants. Native starch comprises amylose, a linear α-glucan having α-1,4-linkage and amylopectin, a branched polysaccharide with both α-1,4-linkage and α-1,6-linkage. Due to the low solubility, high viscosity, and unstable pasting property of native starch, it has been restricted from its application in industries. Although native starch has been widely used in various industries, modification of the same by various chemical, enzymatic and physical methods have been carried out to alter its properties for better performance in several industrial aspects. Physical modification like gamma radiation is frequently used as it is rapid, penetrates deeper, less toxic, and cost-effective. Starch when irradiated with gamma rays is observed to produce free radicals, generate sugars owing to cleavage of amylopectin branches, and exhibit variation in enzymatic digestion, amylose content, morphology, crystallinity, thermal property, and chemical composition. These physicochemical properties of the starch due to gamma radiation are assessed using optical microscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), and its application are discussed.

“…Potato starch is a very refined starch, which contains minimum quantities of proteins and lipids. Besides its lower cost, potato starch has a higher swelling power, solubility, paste clarity and viscosity than the starch obtained from other natural sources such as wheat, rice or corn (Teixeira et al, 2018).…”

Highlights: -Biodegradable potato starch/PVA/rosin blends were developed.  -Addition of rosin to the blends improves mechanical properties substantially.  -Mechanical properties are comparable to those offered by polymers such as LDPE.  -Starch/PVA/rosin blends could be interesting materials for packaging applications. AbstractBiodegradable potato starch/PVA samples containing different concentrations of rosin were prepared by melt-mixing in order to study the enhancement of the properties of native starch films. Glycerol and polyvinyl alcohol (PVA) are commonly used as plasticizers of starch. Their relatively low molecular weight (compared with starch) contributes to a good processability. Rosin is a renewable product whose incorporation in the starch/PVA matrix induces processing aid and reinforcing effects. Its relatively high molecular weight might prevent its migration to the surface of the final product.Water content, solubility in water, mechanical properties, microstructure and dynamic mechanical analysis of the samples were studied. The addition of 8% rosin to starch/PVA blends led to tensile strength values higher than 10 MPa and elongation at break values close to 2000%, values comparable to those offered by conventional polymers used in food packaging, for example LDPE. Furthermore, starch compounds have low cost and high biodegradability.

A critical overview of current approaches to the development of starch-containing packaging, integrating the principles of green chemistry (GC), green technology (GT) and green nanotechnology (GN) with those of green packaging (GP) to produce materials important for both us and the planet is given. First, as a relationship between GP and GC, the benefits of natural bioactive compounds are analyzed and the state-of-the-art is updated in terms of the starch packaging incorporating green chemicals that normally help us to maintain health, are environmentally friendly and are obtained via GC. Newer approaches are identified, such as the incorporation of vitamins or minerals into films and coatings. Second, the relationship between GP and GT is assessed by analyzing the influence on starch films of green physical treatments such as UV, electron beam or gamma irradiation, and plasma; emerging research areas are proposed, such as the use of cold atmospheric plasma for the production of films. Thirdly, the approaches on how GN can be used successfully to improve the mechanical properties and bioactivity of packaging are summarized; current trends are identified, such as a green synthesis of bionanocomposites containing phytosynthesized metal nanoparticles. Last but not least, bioinspiration ideas for the design of the future green packaging containing starch are presented.
