Despite the good biological and antibacterial activities, the p-anisaldehyde is easy to evaporate or degrade during processing and storage. Herein, a new V-type starch-cyclodextrin composite carrier was constructed to efficiently encapsulate p-anisaldehyde in addressing the inherent disadvantages. The introduction of β-cyclodextrin (β-CD) enhanced the short- and long-range ordered structures of the composite carrier. The V-type starch-cyclodextrin composite (VC30) exhibited the highest loading capacity of 142.01 mg/g for p-anisaldehyde, which was significantly higher than that of V-type starch (VS, 97.83 mg/g) and commercial β-CD (128.48 mg/g). The loading capacity of the V-type starch-cyclodextrin composite was positively correlated with its crystallinity and short-range order. The release rate of p-anisaldehyde was in the order of VC30 < β-CD < VS. Under non-cold chain daily storage (25 °C and 57 % relative humidity) for 2 weeks, the p-anisaldehyde of thymol released from complexes was 36 % (VC30), 49 % (β-CD), and 65 % (VS), respectively. Due to the high loading capacity and good sustained release properties, the noncontact preservation of high-value fruit by VC30 controlling p-anisaldehyde release successfully extended the shelf life of cherries from six to twelve days.
尽管对甲氧基苯甲醛具有良好的生物活性和抗菌活性，但在加工和储存过程中容易挥发或降解。在此，构建了一种新型的V型淀粉-环糊精复合载体，以有效包封对甲氧基苯甲醛，解决其固有缺点。β-环糊精（β-CD）的引入增强了复合载体的短程和长程有序结构。V型淀粉-环糊精复合物（VC30）对甲氧基苯甲醛的负载量最高，为142.01 mg/g，显著高于V型淀粉（VS，97.83 mg/g）和市售β-CD（128.48 mg/g）。V型淀粉-环糊精复合物的负载量与其结晶度和短程有序度呈正相关。对甲氧基苯甲醛的释放速率顺序为VC30 < β-CD < VS。在非冷链日常储存（25°C和57%相对湿度）2周后，从复合物中释放的百里香酚对甲氧基苯甲醛分别为36%（VC30）、49%（β-CD）和65%（VS）。由于高负载量和良好的缓释性能，通过VC30控制对甲氧基苯甲醛的释放对高价值水果进行非接触保鲜成功地将樱桃的货架期从6天延长至12天。
