“…Starch is one of the most abundant and low-cost natural polymers, it is generally recognized as GRAS and has recently used in microencapsulation of extracts such as Hibiscus sabdariffa [ 51 ] anthocyanin [ 52 ] extract. Its combined use with other natural polymers for encapsulation processes has also been investigated [ 53 , 54 , 55 ].…”

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.

“…Anthocyanin is an active small molecule that is sensitive to the external environment. Due to their antioxidant and antimicrobial properties, they are used in encapsulated gels and other materials 88 . Because KGM is electrically neutral in an aqueous solution, the primary alcohol group at C6 can be selectively oxidized to the carboxyl group to obtain negatively charged OKGM microspheres.…”

Natural bio‐based materials used in wound dressings have been continuously developed in recent years, and have certain advantages in water retention, biocompatibility, and therapeutic properties. Konjac glucomannan (KGM) is a kind of plant polysaccharide with good cell compatibility and gel properties. Various gels obtained by modification of KGM through physical and chemical methods have great application potential in wound excipients. In the past few years, various KGM‐based wound barrier materials such as hydrogels, xerogel, microspheres, films, and fibers have been continuously researched and developed. The combination of KGM and other polymers can improve the problem of poor mechanical properties and give it new functional properties, which is beneficial to the moisturizing of the wound surface and the release of drugs to promote wound healing. This article reviews the physicochemical properties of KGM and the latest developments in KGM‐based composite gels, reveals the relationship between molecules in KGM‐based composite gels, and looks forward to the research and development prospects of KGM‐based composites in wound dressings.

“…Application of maltodextrin is a suitable alternative in this degradation process since maltodextrin is a good film-forming, water-based factor and used as a coating molecule for polar solid matrices. This drying aid agent is capable of trapping hydrophilic compounds like anthocyanins by protecting their flavylium cations (Mehran;Masoum;Memarzadeh, 2020;Mahdavi et al, 2016;Burin et al, 2011).…”

Blackberry pomace microspheres: An approach on anthocyanin degradation

2020

Blackberry pomace is a rich source of antioxidant compounds, including anthocyanins, but these compounds degrade easily in the presence of high temperatures. Therefore, the present study aimed to evaluate the effect of temperature on anthocyanin degradation in spray-dried blackberry pomace extract. Maltodextrin was used as a drying aid agent in a spray drying process to produce microspheres. The experiment was set up at Maringá-PR, Brazil (23º 25’ 31” S, 51º 56’ 19” W, 596 m altitude). The thermal stability of anthocyanins was evaluated in the presence and absence of copigments at different temperatures ranging from 70 °C to 100 °C using degradation kinetics. The role of maltodextrin in protecting anthocyanins during the spray drying process was studied at high temperatures. The highest anthocyanin stability was found at 70 °C. We also studied the effect of copigment phytic acid on the stability of anthocyanin and found that the copigment plays an important role in anthocyanin protection at high temperatures. The spray drying process with maltodextrin is a feasible technique for the preservation of food products and can improve anthocyanin’s thermal stability. The reuse of industrial wastes, such as blackberry pomace along with preservation techniques, can be a good strategy to reduce their negative impact on the environment.
