Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your work to the Special Issue of the Foods journal, entitled “Encapsulation Technologies and Delivery Systems for Food Ingredients”.

Considering the fact that a great variety of food ingredients are insoluble in water; the fact that they can be degraded during food processing, storage, or transportation upon light, heat, oxygen, etc.; and the fact that their bioactivity can be reduced upon gastrointestinal digestion, their encapsulation for protection and technological purposes is of outmost importance. For this reason, various delivery systems have been developed to encapsulate bioactive food ingredients in order to enhance their stability, bioactivity, and bioavailability, as well as to allow a controlled release at the target site. Various coating materials along with different encapsulation approaches have been employed by academia and the food industry.

In this view, this Special Issue intends to gather recent advances on encapsulation techniques and delivery systems for food ingredients that could be of use both in academia and industry. The submission of original research articles, short communications, and reviews that deal with novel encapsulation carriers and techniques; the physicochemical characterization of obtained encapsulates; the use of encapsulated ingredients for the design of sustainable edible packaging materials (films/coatings); and applications in food products are welcome and encouraged.

We look forward to receiving your contributions.

The use of the appropriate emulsifier is essential for forming a stable nanoemulsion delivery system that can maintain the sustained release of its contents. Health concerns have prompted the search for natural biopolymers to replace traditional synthetic substances as emulsifiers. In this study, an oregano essential oil (OEO) nanoemulsion-embedding system was created using soybean protein isolate (SPI), tea saponin (TS), and soy lecithin (SL) as natural emulsifiers and then compared to a system created using a synthetic emulsifier (Tween 80). The results showed that 4% Tween 80, 1% SPI, 2% TS, and 4% SL were the optimal conditions. Subsequently, the influence of emulsifier type on nanoemulsion stability was evaluated. The results revealed that among all the nanoemulsions, the TS nanoemulsion exhibited excellent centrifugal stability, storage stability, and oxidative stability and maintained high stability and encapsulation efficiency, even under relatively extreme environmental conditions. The good stability of the TS nanoemulsion may be due to the strong electrostatic repulsion generated by TS molecules, which contain hydroxyl groups, sapogenins, and saccharides in their structures. Overall, the natural emulsifiers used in our study can form homogeneous nanoemulsions, but their effectiveness and stability differ considerably. Full article

Plant proteins have gained significant attention over animal proteins due to their low carbon footprint, balanced nutrition, and high sustainability. These attributes make plant protein nanocarriers promising for applications in drug delivery, nutraceuticals, functional foods, and other areas. Zein, a major by-product of corn starch processing, is inexpensive and widely available. Its unique self-assembly characteristics have led to its extensive use in various food and drug systems. Zein’s functional tunability allows for excellent performance in loading and transporting bioactive substances. Lutein offers numerous bioactive functions, such as antioxidant and vision protection, but suffers from poor chemical stability and low bioavailability. Nano-embedding technology can construct various zein-loaded lutein nanodelivery systems to address these issues. This review provides an overview of recent advances in the construction of zein-loaded lutein nanosystems. It discusses the fundamental properties of these systems; systematically introduces preparation techniques, structural characterization, and functional properties; and analyzes and predicts the target-controlled release and bioaccessibility of zein-loaded lutein nanosystems. The interactions and synergistic effects between Zein and lutein in the nanocomplexes are examined to elucidate the formation mechanism and conformational relationship of zein–lutein nanoparticles. The physical and chemical properties of Zein are closely related to the molecular structure. Zein and its modified products can encapsulate and protect lutein through various methods, creating more stable and efficient zein-loaded lutein nanosystems. Additionally, embedding lutein in Zein and its derivatives enhances lutein’s digestive stability, solubility, antioxidant properties, and overall bioavailability. Full article
