“…To know the bactericidal activity of microcomposites loaded with CUR, agar well diffusion method was performed (Dima et al 2014;Buzia et al 2015). In this method, MuellerHinton agar plates were swabbed all over with P. aeruginosa using a sterile swab.…”

In this study, polyphenolic curcumin is entrapped within microcomposites made of biopolymers chitosan (CS) and carboxymethyl cellulose (CMC) formulated by ionic gelation method. Here, different concentrations of two chelating agents, barium chloride and sodium tripolyphosphate, are used to make microcomposites. Thus, the synthesized microparticles were characterized by FTIR, and their surface morphology was studied by SEM. Drug encapsulation efficiency and the drug release kinetics of CS-CMC composites are also studied. The produced microcomposites were used to study antibacterial activity in vitro.

Cyclodextrin - A Versatile Ingredient

Many scientific studies have made advances in the ability to encapsulate natural extracts by cyclodextrins. These studies have addressed the physical and chemical conditions of the encapsulation reactions, employed several types of essential oils and characterized the microcapsules as to their ability to release encapsulated active principles. The essential oils studies with cyclodextrin encapsulation processes have been highly varied. However, the most studied are the essential oils with antimicrobial and antioxidant capacities. The essential antimicrobial and antioxidant oils are easily degraded. In the presence of oxygen, they are oxidized, and at low temperatures, they are volatilized and decomposed. Thus, cyclodextrins are coatings capable of protecting these essential oils from environmental conditions and agents capable of promoting oil degradation, in addition to controlling their release. In this chapter of the book, we review scientific papers that examine the encapsulation of antimicrobial essential oils and antioxidant essential oils with β-cyclodextrins.

Microencapsulation is defined as a process during which the whole envelopment with (bio)catalysts, substrates etc. is included into hydrogel and/or surrounded by a porous polymeric membrane. However, the production of homogeneous, narrow size, distributed capsules is quite troublesome. The main problem is the way of obtaining a large number of capsules with a precisely predefined size. It is possible due to a device called an encapsulator. This equipment allows to produce homogeneous beads and core-shell systems with a predefined size in the range from 400 µm to 1600 µm, which is possible because of special nozzles with different diameters. There are a lot of microcapsule applications. In this paper, we would like to present the construction, principles of operation and selected applications of microencapsulation devices using the example of the BÜCHI-B390 encapsulator.Keywords: microencapsulation; homogeneous beads; core-shell systems; encapsulator BÜCHI-B390 Streszczenie Mikrokapsułkowanie definiowane jest jako proces, w którym całe środowisko zawierające m.in. (bio)katalizatory, substraty itp. zamykane jest w sieci hydrożelu i/lub otaczane porowatą polimerową membraną. Wytwarzanie jednorodnych kapsułek o wąskim rozkładzie wielkości jest dość kłopotliwe. Głównym problemem do rozwiązania jest sposób uzyskania dużej liczby kapsułek o dokładnie zdefiniowanej wielkości. Jest to możliwe przy użyciu urządzenia zwanego enkapsulatorem. Pozwala ono na wytwarzanie homogenicznych kapsułek i układów rdzeń-powłoka o zdefiniowanej wielkości w zakresie od 400 µm do 1600 µm, co jest możliwe za pomocą zestawu dysz o różnych średnicach. Istnieje wiele aplikacji mikrokapsułek. W artykule przedstawiona zostanie budowa, zasada działania i wybrane zastosowania urządzenia do mikroenkapsulacji na przykładzie enkapsulatora BUCHI-B390.Słowa kluczowe: mikroenkapsulacja; homogeniczne mikrokapsułki; układy rdzeń-powłoka; enkapsulator BÜCHI-B390
