A polysaccharides-based delivery system was designed to encapsulate and control the release of peanut peptide (PP). The PP-loaded polyelectrolyte complex (TMC-PP-SA) was fabricated based on the electrostatic self-assembly between n-trimethy chitosan (TMC) and sodium alginate (SA). The complex exhibited uniform spherical morphology, satisfactory stability and high encapsulation efficiency. In vitro release behavior indicated that TMC-PP-SA polyelectrolyte complex could inhibit the release of PP at simulated gastric medium and enhance the release of PP at simulated intestinal medium. Moreover, the antioxidant activity of PP after encapsulation was significantly improved compared with that of directly digested PP. Ex vivo intestinal permeation study confirmed that about 41.76 ± 1.43% PP in TMC-PP-SA could be absorbed in the intestinal. The cytotoxicity measurement indicated that the fabricated TMC-PP-SA polyelectrolyte complex was biocompatible and nontoxic. Therefore, these results indicated that the polysaccharides-based delivery system had great potential in protecting active peptides from degradation and facilitating their absorption.

In order to meet global food requirement, innovation in agricultural techniques and pesticide delivery system will be required for sustainable food supply with minimal harmful impact on environment. This article discusses the synthesis of hydrogels for use in controlled release formulations (CRFs) to increase agricultural output while reducing ecotoxicity and health risks. These hydrogels were designed by graft-copolymerization reaction of polyacrylamide and polyvinyl sulfonic acid onto agar-alginate marine polysaccharides.

Many food nutrients suffer from a series of limitations such as poor water solubility, low stability and inadequate bioavailability. These challenges can be effectively improved by food-based delivery systems (FDSs). FDSs are a series of functional carriers developed based on food-borne macromolecules.

Cancer has a high rate of incidence and mortality throughout the world. Although several conventional approaches have been developed for the treatment of cancer, such as surgery, chemotherapy, radiotherapy and thermal therapy, they have remarkable disadvantages which result in inefficient treatment of cancer. For example, immunogenicity, prolonged treatment, non-specificity, metastasis and high cost of treatment, are considered as the major drawbacks of chemotherapy.
