Ultrastructural and antimicrobial impacts of allyl isothiocyanate incorporated in cellulose, β‐cyclodextrin, and carbon nanotubes nanocomposites

Abstract

Antimicrobial nanobio packaging with controlled-release of active compounds is one of the most promising versions of active packaging. In this study, the antimicrobial effect of allyl isothiocyanate (AIT), complexed or not with β-cyclodextrin (βCD), and carbon nanotubes (CNTs) in cellulose films against Salmonella choleraesuis and Listeria innocua was investigated. Structural changes caused by AIT in bacteria were evaluated by transmission electron microscopy (TEM), as well as changes in the surface of the films, which were analyzed by atomic force microscopy and scanning electron microscopy.

Beneficial Health Effects of Glucosinolates-Derived Isothiocyanates on Cardiovascular and Neurodegenerative Diseases

“…Though without significant differences in AITC plasma levels in volunteers, AITC produced lesser effects in TAS2R38 negative volunteers [ 292 ]. Recently, AITC complexed with β-cyclodextrin and carbon nanotubes was used to study its effect on microbes; the complex maintained slow release of the antimicrobial agent [ 293 ]. This strategy can be employed for the assessment of other effects of AITC and related compounds.…”

Native Cyclodextrins and Their Derivatives as Potential Additives for Food Packaging: A Review

“…The nonpolar cavity of CDs is a favorable environment for the accommodation of molecules of hydrophobic nature and varied sizes, molecular weight, and geometry (Figure 1). In the literature, there are several reports concerning the complexation of native or derivatives CDs involving both solid or liquid compounds, diverse drugs [46,53,55,56], essential oils (EOs) and their constituents [12,20,34,35], flavoring agents and pigments [4,5,58,59], as well as natural antimicrobials [12,35,40]. In Table 2, examples of ICs obtained from the complexation of the different types of CDs with several molecules are displayed.…”

“…CDs and their ICs have been studied with several polymers aiming the preparation of different kinds of packaging for food preservation, from conventional petroleum-based plastics [39,82,83] to sustainable ones [12,35,37,40,59]. In Table 3, examples of CDs/ICs, as well as the support polymer matrix of choice and the main goal of the elaborated packaging are summarized.…”

“…They can be directly blended with the polymer matrices for further development of composite films, which is a simple and common method employed for food packaging manufacturing [94]. Along with this, other methods such as extrusion [39,82], casting [12,40], and electrospinning [65,67,72] can be mentioned for application of CDs/ICs into packaging systems, aiming further industrial use. Examples of these techniques and their principles are schematized in Figure 2.…”

“…In addition to the aforementioned properties, CDs are also able to form complexes with a wide range of substances, from small molecules of low molecular weight to bigger compounds, depending on the type of CD used [11][12][13]. Besides, they can increase the stability of the guest molecules against external factors such as temperature, light, and oxygen [14,15].…”
