As consumer awareness regarding health and nutrition continues to increase, there is a growing demand for fresh, nutritious fruits such as green grapes. However, the short storage life susceptibility of these spoilage lead significant commercial losses. Currently, plastic wrap method commonly used keep grapes but this packaging effect limited not environmentally friendly. Therefore, an urgent need explore sustainable effective preservation methods. In study, high-pressure microfluidization technique was employed prepare essential oil nanoemulsion with ratio Tween 80 clove 1:1, biopolymer-based film solution prepared using dual-modified tapioca starch chitosan loaded nanoemulsion.

Wood plastic composites (WPCs) are widely used green materials composed of a polymer matrix with wood as filler. However, due to the flammable nature substrates in WPC, there is fire hazard associated their use. To address this, this study developed WPCs by adding SiO₂ sol and an intumescent flame retardant (IFR), which included ammonium polyphosphate (APP), melamine (MEL), double pentaerythritol (DPER). This approach aimed investigate combined effects on thermal stability retardancy. FTIR laser particle size analysis confirmed successful incorporation its adhesion flour (WF). The WPC both IFR exhibited excellent flame-retardant performance, limiting oxygen index (LOI) 39.0%, UL-94 V-0 rating, char residue 28.1%. Cone calorimeter tests showed that layer expanded approximately 4 cm, significantly reducing total heat release (THR) rate (HRR). formation silicon-containing from sol, coupled cellulose-IFR reaction, created composite multi-layered structure effectively insulated against heat. These findings suggest exhibit enhanced retardancy, offering potential for application fire-safe building materials.
