Item type:Publication, Antimicrobial film from jackfruit waste powder incorporating clove and ginger essential oils and its application in food packaging(2026-06-01); Krusong, WarawutBioactive composite films were developed utilizing a polyvinyl alcohol (PVA) and jackfruit waste powder (JK PW) matrix, functionalized with either ginger (JK PW–GEO) or clove essential oil (JK PW–CEO). Structural characterization indicated that the essential oils were chemically anchored to the polymer matrix via intermolecular hydrogen bonding, facilitating the formation of a cohesive micro-composite architecture. These chemical interactions significantly enhanced thermal stability; notably, JK PW–GEO films exhibited superior thermal resistance (limiting mass loss to 9 % within the 180–260 °C range) compared to JK PW–CEO films (∼14 % loss). This stability is attributed to the robust retention of non-volatile gingerols within the hydrogen-bonded network, as confirmed by HS-GC–MS/MS analysis. Regarding functional bioactivity, distinct performance profiles were observed: JK PW–CEO films demonstrated exceptional antioxidant capacity (334.75 mg GAE/g; 90.62 % DPPH radical scavenging), whereas JK PW–GEO films exhibited broader antimicrobial efficacy, particularly against resistant bacterial strains such as Bacillus subtilis and Salmonella enterica . In practical application trials, both film formulations effectively extended the shelf life of bread and fresh poultry by mitigating microbial proliferation and suppressing spoilage odors. Sensory evaluation confirmed that the films maintained desirable olfactory profiles, thereby enhancing the perceived quality of the packaged products. Collectively, this study establishes that JK PW-based composites offer a sustainable avenue for active packaging, wherein ginger oil provides superior thermal and antimicrobial stability, while clove oil delivers potent antioxidant protection. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Simultaneous extraction of crude polysaccharides, soluble proteins, gingerols, and shogaols from dried ginger by subcritical water extraction(2025-06-01); ; Subcritical water extraction (SWE) is a remarkable method for the simultaneous extraction of high- and low-polarity bioactive compounds from ginger. This study investigated the effects of temperature, pressure, and extraction time on the crude polysaccharide yield, protein content, total phenolic content (TPC), and amounts of 6-gingerol and 6-shogaol. The pressure was maintained at 30 bars, and the temperature and extraction time were optimized to maximize the polysaccharide yield, protein, TPC, gingerols, and shogaols contents. The rising temperatures (100–160 °C) and extended extraction times (10–50 min) enhanced the yield and TPC but negatively affected protein stability, leading to thermal degradation when the temperature surpassed 180 °C. Specifically, the content of 6-gingerol decreased at high temperatures because of its conversion into 6-shogaol. The optimal extraction conditions were 160 °C for 40 min at 30 bars, resulting in a polysaccharide yield of 8.54 %, protein content of 100.35 mg body surface area/g dry mass, TPC of 18.10 mg Galic acid (GA)/g dry mass, 6-gingerol content of 2.14 mg/g dry mass, and 6-shogaol content of 0.28 mg/g dry mass. Therefore, SWE effectively extracts various polar bioactive compounds from plant materials in a single step.
