“…Figure 6 showed the FTIR spectra of CNC and the ORS/CNC capsules with different contents of CNC. For the ORS/CNC-0 capsule, the stretching vibration peak of -OH group in dehydrated glucose was at 3400 cm -1 , the symmetric vibration absorption peak of -CH group in the glucose ring was at 2940 cm -1 , the stretching vibration peak of crystal water was at 1650 cm -1 , and the band at 1160 cm -1 was the stretching vibration peak of C-O-C and the skeleton vibration peak of C-C and C-H. [28] For the ORS-based capsule with different content of CNC, refering to the characteristic absorption peak of CNC, the band at 1380 cm -1 was the shear vibration peak of -CH 2 of CNC, the band at 1080 cm -1 and 1030 cm -1 were the stretching vibration peaks of O-C and C-O-C of cellulose pyran ring, respectively, and the band at 883 cm -1 was the characteristic absorption peak of C-H in cellulose www.advancedsciencenews.com www.starch-journal.com -1,4-glucoside. [29] Compared with the ORS capsule without CNC, the absorption wavelength of stretching vibration peak of -OH group of the capsule with CNC moved slowly to a lower wavelength, indicating an increase of hydrogen bonding.…”

A hard capsule based on oxidized rice starch (ORS) and cellulose nanocrystals (CNC) is prepared by a dipping method and the glycerol and carrageenan are used as a plasticizer and gelling agent in the ORS/CNC gel solution, respectively. The viscosity of gel solution that is suitable for film-forming/capsule-forming is analyzed. When the content of CNC is 8.0%, the tensile strength of the ORS/CNC composite film is 10.09 MPa and increased by 196.0%. The loss on drying and the disintegration time of the ORS/CNC capsules are also investigated. The ORS/CNC capsules are analyzed by Fourier Transform Infrared spectroscopy (FTIR), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). The results show that the ORS and CNC have good compatibility and good film-forming ability and can be used as excipients to prepare the hard capsules.

“…The coatings were effective at reducing mesophilic bacteria count and fungi count in cold-stored chilies. Other active compounds, such as sodium dehydroacetate and rosemary extract [22], silver nanoparticles [15], pomegranate peel [26], chitosan [10,16,18], N-α-lauroyl-l-arginine ethyl ester monohydrochloride [12] or sodium benzoate and citric acid [24] have also been incorporated into starch-based matrices for the purposes of obtaining antimicrobial packaging materials. Yan et al [22] incorporated sodium dehydroacetate and rosemary extract to oxidized and acetylated corn starch films with sodium alginate that were prepared by casting.…”

“…The incorporation of the highest amount of chitosan (70:30 starch chitosan ratio) in the films led to the reduction in coliforms and total aerobic counts of cold-stored pork meat slices, thus extending their shelf-life. Hasan et al [16] developed films based on brown rice starch and chitosan (starch/chitosan ratio: 70:30, 50:50 and 30:70), plasticized with palm oil and prepared by casting. Films showed a remarkable antimicrobial in vitro effect against grampositive bacteria (S. aureus) and gram-negative bacteria (E. coli).…”

“…Incorporating chitosan did not interfere with the behavior of biodegradation under the conditions considered in compost medium. However, Hasan et al [16] concluded that the biodegradation rate of the starch/chitosan films (at 30:70, 50:50 and 70:30 starch/chitosan ratios) was strongly influenced by the content of chitosan; the greater the chitosan content the lower the biodegradation rate of the films in the composting medium, thus reflecting the antimicrobial effect of chitosan on the compost population.…”

The environmental problem generated by the massive consumption of plastics makes necessary the developing of biodegradable antimicrobial materials that can extend food shelf-life without having a negative impact on the environment. The current situation regarding the availability of biodegradable food packaging materials has been analysed, as well as different studies where antimicrobial compounds have been incorporated into the polymer matrix to control the growth of pathogenic or spoilage bacteria. Thus, the antimicrobial activity of active films based on different biodegradable polymers and antimicrobial compounds has been discussed. Likewise, relevant information on biodegradation studies carried out with different biopolymers in different environments (compost, soil, aquatic), and the effect of some antimicrobials on this behavior, are reviewed. In most of the studies, no relevant effect of the incorporated antimicrobials on the degradation of the polymer were observed, but some antimicrobials can delay the process. The changes in biodegradation pattern due to the presence of the antimicrobial are attributed to its influence on the microorganism population responsible for the process. More studies are required to know the specific influence of the antimicrobial compounds on the biodegradation behavior of polymers in different environments. No studies have been carried out or marine media to this end.

“…The incorporation of chitosan into corn starch increased the antimicrobial activity of films. In this context, biodegradable composite films were produced from brown rice starch (BRS) and chitosan (CH) by Hasan et al [ 73 ]. In this study, the authors evaluated the antimicrobial activity of films against Gram-positive ( Staphylococcus auerues ) and Gram-negative bacteria ( Escherichia coli ).…”

In recent years, scientists have focused on research to replace petroleum-based components plastics, in an eco-friendly and cost-effective manner, with plant-derived biopolymers offering suitable mechanical properties. Moreover, due to high environmental pollution, global warming, and the foreseen shortage of oil supplies, the quest for the formulation of biobased, non-toxic, biocompatible, and biodegradable polymer films is still emerging. Several biopolymers from varied natural resources such as starch, cellulose, gums, agar, milk, cereal, and legume proteins have been used as eco-friendly packaging materials for the substitute of non-biodegradable petroleum-based plastic-based packaging materials. Among all biopolymers, starch is an edible carbohydrate complex, composed of a linear polymer, amylose, and amylopectin. They have usually been considered as a favorite choice of material for food packaging applications due to their excellent forming ability, low cost, and environmental compatibility. Although the film prepared from bio-polymer materials improves the shelf life of commodities by protecting them against interior and exterior factors, suitable barrier properties are impossible to attain with single polymeric packaging material. Therefore, the properties of edible films can be modified based on the hydrophobic–hydrophilic qualities of biomolecules. Certain chemical modifications of starch have been performed; however, the chemical residues may impart toxicity in the food commodity. Therefore, in such cases, several plant-derived polymeric combinations could be used as an effective binary blend of the polymer to improve the mechanical and barrier properties of packaging film. Recently, scientists have shown their great interest in underutilized plant-derived mucilage to synthesize biodegradable packaging material with desirable properties. Mucilage has a great potential to produce a stable polymeric network that confines starch granules that delay the release of amylose, improving the mechanical property of films. Therefore, the proposed review article is emphasized on the utilization of a blend of source and plant-derived mucilage for the synthesis of biodegradable packaging film. Herein, the synthesis process, characterization, mechanical properties, functional properties, and application of starch and mucilage-based film are discussed in detail.
