High-performance carboxymethyl starch/PVA based intelligent packaging films engineered with Cu-Trp nanocrystal as functional compatibilizer.

A spindle-like Cu-based framework (Cu-Trp, Trp = L-Tryptophan) nanocrystal with ammonia-responsiveness was fabricated via simple aqueous solution approach, and it was subsequently explored as a functional compatibilizer of carboxymethyl starch/polyvinyl alcohol (CMS/PVA) blend toward constructing high-performance intelligent packaging films. The results showed that incorporation of Cu-Trp nanocrystal into CMS/PVA blend resulted in significant promotions regarding to the compatibility, mechanical strength (42.92 MPa), UV-blocking (with UV transmittance of only 2.

pH-responsive citral microcapsules with tannic acid-Fe coordination complexes.

Citral is one of the most important aromatic ingredients in foods and beverages for its distinct lemon-like odor. However, the fast evaporation and oxidation limit these applications. Herein, citral microcapsules were constructed by tannic acid-Fe coordination complexes (citral@TA-Fe).

Dual stabilization of Pickering emulsion with epigallocatechin gallate loaded mesoporous silica nanoparticles.

Oxidation in food emulsions remains challenging to keep food quality and shelf-life. In this paper, a dual stabilization to both oil phase and antioxidant in Pickering emulsion is presented. Mesoporous silica nanospheres (MSN) were prepared to incorporate epigallocatechin gallate (EGCG), a typical plant-based antioxidant.

Supersmall Dendritic Mesoporous Silica Nanospheres as Antioxidant Nanocarriers for Pickering Emulsifiers.

Encapsulation of flavor and aromatic compounds in emulsions holds great potential for development of novel formulations in food applications. In this paper, supersmall dendritic mesoporous silica nanospheres (DMSNs) were fabricated by the one-pot strategy. The morphologies of DMSNs were directly tuned in terms of diameter from 35 ± 2 to 85 ± 4 nm.
