In this paper, litchi freshness rapid non-destructive evaluating method using electronic nose (e-nose) and non-linear stochastic resonance (SR) was proposed. EN responses to litchi samples were continuously detected for 6 d Principal component analysis (PCA) and non-linear stochastic resonance (SR) methods were utilized to analyze EN detection data. PCA method could not totally discriminate litchi samples, while SR signal-to-noise ratio (SNR) eigen spectrum successfully discriminated all litchi samples. Litchi freshness predictive model developed using SNR eigen values shows high predictive accuracy with regression coefficients R(2) = 0 .99396.

The postharvest losses of litchi caused by litchi downy blight are considerably high. We identified a natural antifungal volatile pyrone, 6-pentyl-2-pyran-2-one (6PP), synthesized by LS019-2 and investigated as biocontrol for litchi downy blight and preservation. 6PP significantly inhibited the growth and sporangial germination of , the causal agent of litchi downy blight, and caused severe cellular and intracellular destructions, as evidenced by electron microscopic analysis.

In this study, a bilayer antibacterial chromogenic material was prepared using chitosan (CS) and hydroxyethyl cellulose (HEC) as inner substrate, mulberry anthocyanins (MA) as a natural tracer, and titanium dioxide nanoparticles (nano-TiO)/CS:HEC as a bacteriostatic agent for the outer layer. By investigating their apparent viscosity and suitability for 3D printing links, the optimal ratio of the substrates was determined to be CS:HEC = 3:3. Viscosity of the CH was moderate.

Article Synopsis
- Polysaccharide films with protein additives show promise in agriculture and food, but their effectiveness is hindered by the incompatibility between hydrophobic proteins and hydrophilic polymers.
- This research improves compatibility by using a chemical crosslinking method involving zinc ions from curcumin-loaded zeolitic imidazolate framework-8 (Cur-ZIF-8) with chitosan (CS) and zein, leading to significantly enhanced properties such as elongation at break and oxygen barrier capabilities.
- Additionally, the improved composite (Cur-ZIF-8/CS/Zein) exhibits excellent antibacterial and antioxidant properties, and effectively extends the freshness of litchis by at least 8 days, highlighting its potential for broader applications

The anthocyanin-rich litchi shell extract (LE) was mixed with the matrix to prepare active/intelligent food packaging composite films. The microstructure and properties of composite films were characterized. The results showed that the composite films incorporated with LE had texture-oriented layered, compact, uniform cross-sections.
