![]() These vesicles may encapsulate both lipophilic and hydrophilic bioactives, for the food, cosmetic or pharmaceutical purposes. Techniques including spray drying, co-crystallization, freeze-drying, and emulsification have been proposed for encapsulation of bioactives.Ī particular group of carriers are vesicular systems, which are colloidal particles where a bilayer comprised of amphiphilic molecules encloses a hydrophilic molecule. ![]() It will also enhance the solubility of bioactives in a lipophilic or aqueous medium, and mask their unfavorable sensory properties that may evolveduring storage or processing (Babazadeh, Jafari, & Shi, 2019). An ideal encapsulation system will protect the nutraceutical payload from biochemically harsh environments both during food processing and in passage through digestive tract without compromising bioavailability. In addition, some formulations are characterized by low in vivo performance due to intricate biochemical reactions that lead to weak bioavailability and reduced absorption.Įncapsulation of the nutraceutical components in food-grade delivery systems might address this problem. In achieving this aim, reduced water solubility and chemical instability of bioactives during storage and processing are the two most important challenges (Castro Coelho, Nogueiro Estevinho, & Rocha, 2021). To address this problem, novel bioactive enriched low-fat functional food products can be created as therapeutic formulations. However, the related diminishment of lipids consumption can result in a shortage of vital lipid-soluble bioactives in our diet. Thus, the drive for the adoption of functional foods, low-fat diets, and more natural-healthy foods continues to expand. For the maintenance of health, the role of dietary habits, health and the minimization of drug consumption are all important. The importance of access to nutritional dietary components is self-evident. ![]() The niosomes are distributed throughout the nanofibers evenly and are kept intact during ES process. Niosome-embedded EFs aid the sustained release of herbal bioactives and enhance their antimicrobial activity against Gram-positive/negative bacteria. ![]() In addition, double encapsulation improves the long-term release of bioactives and can address the problem of burst release. Embedding liposomes into nanofibers causes better antioxidant and sensory properties as well as substantial reduction of bacterial load when applied as packaging layers this technology also significantly enhances the photo-stability of bioactives. Finally, we examine how vesicular embedded EFs can be applied in different fields of antioxidant and antimicrobial food packaging as well as the enhancement of bioaccessibility and protection of loaded bioactives. Next, methods for encapsulation of different bioactives through ES techniques via meat analogue proteins are discussed: this is focused on the strength of encapsulation through vesicular systems. In this review, the principles of electrospinning (ES) are briefly summarized and the characteristics of some important plant proteins used as electrospun fibers (EFs) are described with applications as meat analogues. This is the driver for the adoption of emerging new technologies including electrohydrodynamic processing. There are difficulties with some traditional technologies for biopolymer coating of bioactive-loaded vesicular systems such as spray-drying and freeze-drying high temperatures during spray drying can damage the loaded sensitive bioactives and freeze-drying is expensive.
