“…Chollakup et al [17] investigated cassava starch film, who proved the hydrophobic interactions and hydrogen bonding present in cassava starch and whey protein blended films to explain their barrier mechanisms at the molecular level. Lin et al [18] utilized cellulose nanocrystals and PVA (polyvinyl alcohol)/glycerol to modify the formability of oxidized starch films with excellent WVP, surface free energy, and oxygen resistance. e characteristic properties of starch-PLA (polylactic acid) composite films [19] significantly improved with the use of cellulosic strengthening agents (cellulosic fibers and cellulose nanocrystals) and coffee husk extracts to enhance tensile properties, reduced barrier permeability, and endowed additional antioxidant capacity to food packaging systems.…”

The use of plastics is resisted worldwide. Therefore, finding alternatives to plastic packaging products is an urgent issue. This work was dedicated to the preparation of biodegradable composited films with potato starch, glycerol, and gelatin. The formulation of the biodegradable film was first optimized via response surface methodology combined with the multi-index comprehensive evaluation method that considered physical properties (thickness, water solution (WS), tensile strength (TS) and elongation at break (E%)) and barrier property (light transmittance (T%)). Results indicated that the optimal conditions were 2.5% starch, 2.0% glycerol, and 1.5% gelatin (based on water). The optimized film presented excellent properties with TS of 4.47 MPa, E% of 109.91%, WS of 43.64%, and T% of 41.21% at 500 nm, and the comprehensive evaluation score of the composite film was 28.68. Moreover, a model verification experiment was further conducted, which proved that the predicted value highly matched experimental values, indicting the credibility and accuracy of the model. The resulting films were further characterized on the basis of rheological measurements, Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The rheological measurements proved that the film-forming solution exhibited low shear viscosity and non-Newtonian fluid behavior. FTIR and SEM revealed excellent compatibility among starch, glycerol, and gelatin. Hence, the resulting optimized film may be expected to provide theoretical basis and technical support for the food packing industry.

“…Spectroscopy Fourier Transform Infrared Spectroscopy (FTIR) was used to identify the functional groups of breadnut seeds starch in the ranges of 500-4000 cm -1 using resolution. The functional groups were identified after the photoelectric detector generated a vibration graph [14]. The FTIR spectroscopic graph of breadnut seeds starch is shown in Figure 3.…”

“…One of the promising fillers in the manufacture of bioplastics is starch because polysaccharide starch is biodegradable, widely available, and useful as a coating to replace petroleum-based polymer materials [14]. According to Yuda, et al [15], breadnut has a starch content of 30.15-39.09%.…”

Starch can be produced from many plant varieties and through various processing methods. Breadnut (Artocarpus camansi) is a plant variety containing seeds that are rich in carbohydrates to produce starch. However, it has not been widely used and converted into useful products because it is still traditionally considered waste. Starch can be produced physically, chemically, and enzymatically. In this study, the starch extraction from breadnut seeds was conducted using a chemical method, namely immersion into sodium metabisulfite (Na2S2O5) at concentrations of 600, 800, and 1000 ppm. Characterization includes starch content, water content, amylose content, crystallinity using XRD (X-Ray Diffraction), functional groups using FTIR (Fourier Transform Infrared Spectroscopy), and morphology using SEM (Scanning Electron Microscope). The results showed the immersion of breadnut seeds into sodium metabisulfite affected the physicochemical properties. The produced starch content ranged from 53.56-54.87%; water content ranged from 5.83-6.66%; amylose content ranged from 27.07-30.80%. Based on the X-ray diffraction pattern, breadnut seed starch belonged to Type B which reached the highest peak at 17° 2θ. The functional group also showed the same FTIR spectrum in the breadnut seeds starch. Meanwhile, the morphological result showed that the starch granules of breadnut seeds ranged from 6.6 μm to 8.1 μm.

Natural biopolymers are an interesting resource for edible films production, as they are environmentally friendly packaging materials. The possibilities of the application of main animal proteins and natural polysaccharides are considered in the review, including the sources, structure, and limitations of usage. The main ways for overcoming the limitations caused by the physico-chemical properties of biopolymers are also discussed, including composites approaches, plasticizers, and the addition of crosslinking agents. Approaches for the production of biopolymer-based films and coatings are classified according to wet and dried processes and considered depending on biopolymer types. The methods for mechanical, physico-chemical, hydration, and uniformity estimation of edible films are reviewed.
