摘要: Star anise essential oil (SAEO) has a variety of antioxygenic and antimicrobial properties, is widely used in food preservation. However, its application still challenging due to poor water solubility physicochemical stability. We now report that encapsulation SAEO hydroxypropyl-β-cyclodextrin (HPCD) enhances solubility, as well thermal, storage, photostability. The encapsulated by HPCD was increased 47.5 times at 45 °C, the onset temperature thermal volatilization delayed least 200 °C. material also more uniformly stably dispersed xanthan gum, thus released controlled manner. Importantly, fresh-cut Chinese yam coated with gum containing effectively preserved, assessed using weight loss, L* value, browning index, polyphenol oxidase activity. data suggest reduced loss samples than 30%, inhibitory effect on activity nearly 8 7 times, respectively. Collectively, promising preservative coat for fruits vegetables.
