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.

“…This could be achieved by encapsulation technologies, such as spray drying, liposome entrapment, nanoencapsulation, freeze-drying, inclusion complexation, and cocrystallization. Through these encapsulation systems, the stability and physicochemical properties of nutrients were enhanced compared to the non-encapsulated ingredients [65].…”

“…In the food industry, encapsulation is a useful tool to improve the delivery of biomolecules (antioxidants, minerals, vitamins, lycopene, fatty acids) and living cells (antibiotic) into food. Since most of the nutraceuticals are sensitive and labile, the goal of encapsulating nutraceuticals is to reduce the damage and protect the bioactive agents from undesirable circumstances [65]. Beside bioactive protection, their bioavaibility was also improved due to an increase in surface-to-volume ratio by reducing the particle size into the nano-range [67,68].…”

Plant-derived polyphenolic compounds have gained widespread recognition as remarkable nutraceuticals for the prevention and treatment of various disorders, such as cardiovascular, neurodegenerative, diabetes, osteoporosis, and neoplastic diseases. Evidence from the epidemiological studies has suggested the association between long-term consumption of diets rich in polyphenols and protection against chronic diseases. Nevertheless, the applications of these phytochemicals are limited due to its low solubility, low bioavailability, instability, and degradability by in vivo and in vitro conditions. Therefore, in recent years, newer approaches have been attempted to solve the restrictions related to their delivery system. Nanoencapsulation of phenolic compounds with biopolymeric nanoparticles could be a promising strategy for protection and effective delivery of phenolics. Poly(lactic-co-glycolic acid) (PLGA) is one of the most successfully developed biodegradable polymers that has attracted considerable attention due to its attractive properties. In this review, our main goal is to cover the relevant recent studies that explore the pharmaceutical significance and therapeutic superiority of the advance delivery systems of phenolic compounds using PLGA-based nanoparticles. A summary of the recent studies implementing encapsulation techniques applied to polyphenolic compounds from plants confirmed that nanoencapsulation with PLGA nanoparticles is a promising approach to potentialize their therapeutic activity.

“…Dentro de este grupo de procesos se puede encontrar la fluidización y la inyección de fusión. Por el contrario, los procesos químicos de microencapsulación logran la encapsulación principalmente por un mecanismo de reacción química; entre estos procesos se encuentran el entrampamiento de liposomas y la técnica sol-gel [7]. Uno de los métodos más utilizados por las industrias alimenticias es el secado por atomización, debido a que no requiere una gran inversión para su operación.…”

En la actualidad,el desarrollo de nuevos productos alimenticios que posean la incorporación de principios activos se ha convertido en un factor de vital importancia para que las industrias alimenticias puedan competir en el mercado, brindando solución a las necesidades actuales y futuras de sus clientes. La microencapsulación se presenta como una novedosa alternativa para generar productos con valor agregado, ya que permite evitar la degradación de compuestos activos, así como también desagradables cambios en el sabor, especialmente en el caso de los aceites esenciales. Se estudió la microencapsulación de aceite de oliva y aceite de almendra desde la formulación de una emulsión para generar las microcápsulas que posteriormente se obtuvieron por el método de secado por atomización en el Minispray Dryer B-290. Se analizaron la morfología, el porcentaje de aceite encapsulado y las tasas de liberación dentro del cuerpo humano. Los resultados obtenidos permitieron determinar que es posible encapsular aceites esenciales por el método de secado por atomización. Esto permite prevenir la degradación de los ácidos grasos en el almacenamiento de aceites y la digestión gástrica, además de entregarlos directamente en el intestino delgado. Por otro lado, un aceite con mayor porcentaje de ácidos grasos incrementa la tendencia de aglomeración de las microcápsulas. Finalmente, se comprobó que las microcápsulas con maltodextrina como material de pared pueden retener mayor cantidad de aceite de almendra, en comparación con el aceite de oliva
