Heteroatom-doped carbon dot (CD)-reinforced flexible, antioxidant, and UV-resistant polymeric thin films have been fabricated by a facile physical compounding strategy associated with the ‘cast and peel’ technique. The prepared CDs were found to be stable in aqueous media because of their zeta potential value (−5.85 mV). There was no significant change in the zeta potential values during 7 days of storage, indicating the long-term stability of CPCDs. CD-reinforced thermoplastic starch (TPS)/κ-carrageenan hybrid films have been developed as antioxidants to improve the shelf-life of agro-products. Besides this, they also qualified for mechanical strength (>40 MPa), transparency (∼77%), nondeteriorative dimensional integrity at a high relative humidity (∼97%), and UV-resistant properties. For assessing the food preservation behavior, the leaching of CDs also has been studied by time-dependent sustained release in different food simulant media, where it showed a gradual alteration of entrapment efficacy in high-polarity gradient environments. The mechanism of CD release has been obtained from the non-Fickian fittings of the initial preplateaued kinetic data. Surprisingly, when these nanodots were arrested inside the polymer matrix, the film also showed excellent water vapor impermeability, low moisture retention, sufficient toughness, and superficial compliance to external flexing and stretching. Also, CD-based TPS/κ-carrageenan films exhibited strong antioxidant activity, as determined by 1,1-diphenyl-2-picrylhydrazyl (>85%) and 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid assays (>90%). Thus, these hybrid films could be promoted as ideal alternatives for food packaging with their thin, flexible, tough, antioxidant, and moisture-impermeable properties.

A shikonin embedded smart and active food packaging film was produced using a binary mixture of gelatin and cellulose nanofiber (CNF). Shikonin is an alcohol-soluble natural pigment extracted from Lithospermum erythrorhizon root. The fabricated film showed good pH-responsive color changes and volatile gas sensing properties. Moreover, the film exhibited excellent antioxidant and antibacterial activity against foodborne pathogens. The shikonin incorporated gelatin/CNF-based film showed excellent UV-light barrier properties (>95%) and high tensile strength (>80 MPa), which is useful for food packaging. The hydrodynamic properties of the film were also slightly changed in the presence of shikonin, but the thermal stability and water vapor permeability remained unaffected. Thus, the inclusion of shikonin in the gelatin/CNF-based film improves not only the physical properties but also the functional properties. The film’s color indicator properties also clearly show shrimp’s freshness and spoilage during storage for 48 h. The shikonin-based functional film is expected to be a promising tool for multi-purpose smart and active food packaging applications.

“…In the current society there is an ever-increasing unmet demand for biodegradable materials from renewable sources with the potential to be used for food storage and transportation. The most promising raw materials for obtaining such materials are natural polysaccharides, such as cellulose, starch, and chitosan [ 1 , 2 , 3 ]. Packaging materials based on biopolymers often need additional modification and improvement of performance characteristics.…”

Comprehensive Enzymatic Conversion of Starch for the Food Industry

et al. 2022

This study demonstrated the feasibility of comprehensive enzymatic conversion of starch for non-waste applications in food industry. Enzymatic conversion of starch gives rise to nano-sized particles that can be used for manufacturing biodegradable and edible packaging materials and glucose syrup for replacing sugar in confectionery formulations. The 96 h enzymatic hydrolysis yielded starch nanoparticles smaller than 100 nm. Films based on nano-sized starch particles have promising physicochemical properties for manufacturing biodegradable and edible packaging materials. Such properties as reduced moisture content, increased homogeneity, crystallinity, and high initial thermal stability improve the mechanical and performance characteristics of the final food packaging materials. During film formation from starch subjected to preliminary mechanical amorphization, the polymer chain is recrystallized. The C-type crystal structure of starch is converted to the B-type structure. The supernatant obtained by starch hydrolysis can be used for producing glucose syrup. The resulting glucose syrup can be used as a sugar substitute in production of confectionery products. No objective technological differences in properties of glucose syrup obtained by comprehensive conversion of starch and the commercially available glucose syrup derived from sucrose were revealed.
