“…Originally, nanotechnology was recognized as a promising enabler for improving material properties, such as barrier and mechanical properties [17]. Later, the technology rapidly expanded to numerous applications within active and intelligent food packaging [18][19][20][21][22]. Encapsulation by inorganic nanocarrier matrices has lately received considerable attention in research.…”

Essential oils and their active components have been extensively reported in the literature for their efficient antimicrobial, antioxidant and antifungal properties. However, the sensitivity of these volatile compounds towards heat, oxygen and light limits their usage in real food packaging applications. The encapsulation of these compounds into inorganic nanocarriers, such as nanoclays, has been shown to prolong the release and protect the compounds from harsh processing conditions. Nevertheless, these systems have limited shelf stability, and the release is of limited control. Thus, this study presents a mesoporous silica nanocarrier with a high surface area and well-ordered protective pore structure for loading large amounts of natural active compounds (up to 500 mg/g). The presented loaded nanocarriers are shelf-stable with a very slow initial release which levels out at 50% retention of the encapsulated compounds after 2 months. By the addition of simulated drip-loss from chicken, the release of the compounds is activated and gives an antimicrobial effect, which is demonstrated on the foodborne spoilage bacteria Brochothrix thermosphacta and the potentially pathogenic bacteria Escherichia coli. When the release of the active compounds is activated, a ≥ 4-log reduction in the growth of B. thermosphacta and a 2-log reduction of E. coli is obtained, after only one hour of incubation. During the same one-hour incubation period the dry nanocarriers gave a negligible inhibitory effect. By using the proposed nanocarrier system, which is activated by the food product itself, increased availability of the natural antimicrobial compounds is expected, with a subsequent controlled antimicrobial effect.

“…The purpose of active food packaging (AP) is to solve the problem of food loss by incorporating additives, such as antimicrobial compounds, preservatives, oxygen absorbers, water vapor absorbers, and ethylene scavengers into the packaging materials to extend the shelf life of food. AP not only extends the shelf life of foods but also prevents foodborne diseases and preserves the nutritional quality of foods. − …”

Ethylene, the ripening hormone produced by climacteric plants, is an important parameter that determines the shelf life of fresh fruits. Cinnamaldehyde (CA) encapsulated in halloysite nanotube (HNT) nanocarriers was studied as an ethylene production inhibition agent. The slow release of CA from HNT-CA nanohybrids was demonstrated to last for over 180 d and cause inhibition of ethylene production in bananas. The HNT-CA nanohybrids were incorporated into polypropylene (PP) via melt extrusion, resulting in PP/HNT-CA nanocomposite films with suitable mechanical properties for use as flexible packaging. Bananas stored in PP/HNT-CA nanocomposite film bags for 7 d presented significantly lower weight loss, higher firmness, and higher color scores, indicating freshness, than bananas stored in neat PP film bags. The nanocomposite films presented in this study were shown to slow down the ripening by inhibiting ethylene production, and they have strong potential as active food packaging materials that can prevent spoilage of ethylene-sensitive fresh fruits.

“…Эксплуатация изделий из полимерных композиционных материалов (ПКМ), в особенности в условиях тропического климата, требует повышения стойкости ПКМ к биодеструкции с одновременным обеспечением заданных механических характеристик [1][2][3][4]. Один из перспективных подходов к решению данной задачи основан на использовании дисперсных частиц наполнителя полимера, в качестве которых выбирают частицы, проявляющие токсичность к микроорганизмам,биодеструкторам [5,6]. Варьировать механическими характеристиками таких ПКМ возможно, в том числе путем формирования на поверхностях дисперсных частиц полимерной оболочки определенной толщины.…”

Изменение некоторых механических характеристик дисперсно-армированных полимерных композиционных материалов с биоцидным эффектом возможно обеспечить путем контроля толщины полимерной оболочки на поверхностях дисперсных частиц наполнителя. В работе предложен косвенный контроль толщины оболочки полилактида на поверхностях дисперсных частиц оксида меди (I) с использованием метода титрования. Для калибровки полученных результатов титрования в работе определяли смещение максимума гистограммы распределения частиц (капсулированных относительно исходных частиц) по размерам по анализу микрофотографий. Предложена аппроксимация временной зависимости концентрации ионов меди в таком растворе экспоненциальной функцией вида. Нелинейность измерительной характеристики, связывающей постоянную времени аппроксимирующей экспоненциальной функции с толщиной оболочки связана с различным значением плотности оболочки полилактида разной толщины.
