“…FT-IR is one of the important techniques that used for detection of possible chemical groups present in the tested materials ( Rajkumar et al, 2020 ). In our study we have confirmed the available functional groups of chitosan and presenting converted chemicals groups of chitosan loaded plant essential oil.…”

“…When the synthesis process, chitosan beads is acted as a stable loading system, but it depends on the size and types of the crosslinking agents ( Topuz and Uyar, 2020 ). The universal crosslinking agent is sodium tripolyphosphate (TPP), which is used in nanoencapsulation, even formed capsules are labile in the aqueous system based on the pH and ionic strength ( Rajkumar et al, 2020 ). Basically, it shows on rod-like, crystal structures with larger surface area and hold the negatively charged sulphate groups on the cellulose backbone due to the process of hydrolysis.…”

The development of antibiotic resistant in K. pneumoniae is an emerging thread worldwide due to the poor antimicrobial drugs. To overcome this issue, researchers are focused on plant material and their essential oils to fight against multi drug resistant bacteria. In this context, the current study was concentrated in medicinal plant of guva leaves and their essential oils to combat multi drug resistant bacterial infections. The essential oils were successfully screened and confirmed by HRLC-MS analysis. The anti-bacterial ability of the compounds were loaded into the chitosan nanoparticles and proved by FT-IR analysis. In addition, the chitosan loaded essential oils morphology was compared with chitosan alone in SEM analysis and suggested that the material was loaded successfully. Further, the anti-bacterial ability of the chitosan loaded essential oils were primarily confirmed by agar well diffusion method. At the 100 µg/mL of lowest concentration of chitosan loaded essential oils, the multi-drug resistant K. pneumoniae was inhibited with 96% and confirmed by minimum inhibition concentration experiment. Hence, all the experiments were proved that the essential oils were successfully loaded into the chitosan nanoparticles, and it has more anti-bacterial activity against multi-drug resistant K. pneumoniae.

“…Clove [ 102 , 103 , 104 , 105 , 106 ] and thyme [ 107 , 108 , 109 , 110 , 111 ] EOs have been largely used in encapsulation studies, mostly through the ionic gelation technique, targetingdifferent applications. However, a wide range of EOs-based chitosan nanoparticles have also been referred to the literature over the last five years, such as mint ( Mentha piperita ) [ 111 , 112 ], cardamom [ 113 ], krill oil ( Euphausia superba ) [ 114 ], lime [ 115 ], orange [ 116 ], lavender [ 109 , 116 ], Achillea millefolium [ 117 ], Cymbopogon martini [ 118 ], citrus [ 119 ], Piper nigrum [ 120 ], peppermint or green tea EOs [ 3 , 121 ].…”

Chitosan is a cationic natural polysaccharide, which has emerged as an increasingly interesting biomaterialover the past few years. It constitutes a novel perspective in drug delivery systems and nanocarriers’ formulations due to its beneficial properties, including biocompatibility, biodegradability and low toxicity. The potentiality of chemical or enzymatic modifications of the biopolymer, as well as its complementary use with other polymers, further attract the scientific community, offering improved and combined properties in the final materials. As a result, chitosan has been extensively used as a matrix for the encapsulation of several valuable compounds. In this review article, the advantageous character of chitosan as a matrix for nanosystemsis presented, focusing on the encapsulation of natural products. A five-year literature review is attempted covering the use of chitosan and modified chitosan as matrices and coatings for the encapsulation of natural extracts, essential oils or pure naturally occurring bioactive compounds are discussed.

“…Chitosan biopolymer is generally recognized as safe due to its non-toxicity, biocompatibility, and biodegradability. It has gained a great deal of attention in last few years as an encapsulation wall material because of some of its properties such as being insecticidal, antimicrobial, antioxidant, and having film-forming properties [ 217 , 218 , 219 , 220 ]. Therefore, chitosan has been used to encapsulate EOs such as clove [ 221 ], Cuminum cyminum [ 215 ], Bunium persicum [ 222 ], and Foeniculum vulgare [ 217 ].…”

Antibacterial, Antifungal, Antimycotoxigenic, and Antioxidant Activities of Essential Oils: An Updated Review

et al. 2020

The interest in using natural antimicrobials instead of chemical preservatives in food products has been increasing in recent years. In regard to this, essential oils—natural and liquid secondary plant metabolites—are gaining importance for their use in the protection of foods, since they are accepted as safe and healthy. Although research studies indicate that the antibacterial and antioxidant activities of essential oils (EOs) are more common compared to other biological activities, specific concerns have led scientists to investigate the areas that are still in need of research. To the best of our knowledge, there is no review paper in which antifungal and especially antimycotoxigenic effects are compiled. Further, the low stability of essential oils under environmental conditions such as temperature and light has forced scientists to develop and use recent approaches such as encapsulation, coating, use in edible films, etc. This review provides an overview of the current literature on essential oils mainly on antifungal and antimycotoxigenic but also their antibacterial and antioxidant activities. Additionally, the recent applications of EOs including encapsulation, edible coatings, and active packaging are outlined.
