Bioactive compounds are a type of chemical substance found in plant sources. Lycopene, carotenoids, phytochemicals, phenolic compounds, and anthocyanin are a few bioactive compounds. These compounds are rich in antimicrobial, antioxidant, and free radical‐scavenging properties. But these compounds are easily degraded. In order to enhance the chemical stability and the retention properties of functional ingredients, encapsulation is indispensable. This paper reviews the two important methods of encapsulation of bioactive components and the novelties in these techniques. Spray‐drying and freeze‐drying techniques are commonly used for encapsulation in the food and pharmaceutical industries. The former is a quick and high‐temperature process, while the latter is a time‐consuming and low‐temperature procedure. The inlet temperature during spray drying is maintained between 120 and 190°C, whereas during freeze drying, a temperature of −80°C to −20°C is maintained. For effective encapsulation, the optimization of the process conditions such as the temperature, pressure, feed rate, airflow rates, and selection of wall materials are essential. In this paper, the influence of these parameters on encapsulation efficiency and product stability is also discussed. Practical Applications The spray‐drying and freeze‐drying techniques find their application in the food and chemical industries for the purpose of encapsulation and drying. The former technique helps transform liquid foods to powder and thereby extending their shelf life. The encapsulation of some biologically active components helps better retention and delivery of the components. Spray drying is a technique in which liquid foods are converted to powdered form. These techniques have been used for a very long time in the dairy industry. But in recent times, they have been used in the pharmaceutical industries as well. Their main application in the pharmaceutical industry is drug delivery. Freeze drying is a low‐temperature encapsulation process which is mainly used for the encapsulation of functional foods. The most commonly spray‐dried active materials include oleoresins, natural food colors, natural antioxidants, lipids, flavors, and functional foods. Probiotic sources such as bacterial cultures are the main freeze‐dried products. In this review, the practical applications of the techniques are elaborated.

“…The authors encapsulated tucumã (Astrocaryum aculeatum) pulp with various biopolymers and observed that the modified starch was the one with best bioactive compound retention. Similar work was performed by Ravichai and Muangrat [89], who used different biopolymers to encapsulate phenolic compounds derived from fermented Miang wastewater by freeze-drying, and the authors selected gum arabic as the best coating material for encapsulating the highest amount of phenolic compounds. Even so, it is important to note that the Miang powder encapsulated with modified starch maintained its antioxidant properties.…”

Starch as a Matrix for Incorporation and Release of Bioactive Compounds: Fundamentals and Applications

et al. 2022

Due to its abundance in nature and low cost, starch is one of the most relevant raw materials for replacing synthetic polymers in a number of applications. It is generally regarded as non-toxic, biocompatible, and biodegradable and, therefore, a safe option for biomedical, food, and packaging applications. In this review, we focused on studies that report the use of starch as a matrix for stabilization, incorporation, or release of bioactive compounds, and explore a wide range of applications of starch-based materials. One of the key application areas for bioactive compounds incorporated in starch matrices is the pharmaceutical industry, especially in orally disintegrating films. The packaging industry has also shown great interest in using starch films, especially those with antioxidant activity. Regarding food technology, starch can be used as a stabilizer in nanoemulsions, thus allowing the incorporation of bioactive compounds in a variety of food types. Starch also presents potential in the cosmetic industry as a delivery system. However, there are still several types of industry that could benefit from the incorporation of starch matrices with bioactive compounds, which are described in this review. In addition, the use of microbial bioactive compounds in starch matrices represents an almost unexplored field still to be investigated.

“…The use of starch as a PGPB carrier is still little reported in the literature, although in recent decades its use for the encapsulation of bioactive compounds has been extensively discussed and studied [ 105 ], such as particles to encapsulate curcumin for pharmaceutical applications [ 111 , 112 ], as films to encapsulate antioxidants for food packaging [ 113 , 114 ], and as films to enhance the stability of phenolic compounds to be used in food technology [ 115 , 116 ].…”

Perspectives on the Use of Biopolymeric Matrices as Carriers for Plant-Growth Promoting Bacteria in Agricultural Systems

The subject of this review is to discuss some aspects related to the use of biopolymeric matrices as carriers for plant-growth promoting bacteria (PGPB) in agricultural systems as a possible technological solution for the establishment of agricultural production practices that result in fewer adverse impacts on the environment, reporting some promising and interesting results on the topic. Results from the encapsulation of different PGPB on alginate, starch, chitosan, and gelatin matrices are discussed, systematizing some advances made in this area of knowledge in recent years. Encapsulation of these bacteria has been shown to be an effective method for protecting them from unsuitable environments, and these new products that can act as biofertilizers and biopesticides play an important role in the establishment of a sustainable and modern agriculture. These new products are technological solutions for replacing deleterious chemical fertilizers and pesticides, maintaining soil fertility and stability, and improving crop productivity and food security. Finally, in the near future, scale-up studies will have to provide new information about the large-scale production of these materials as well as their application in the field under different biotic and abiotic stress conditions.
