For the protection of anthocyanins from berries of Berberis lycium Royle, the freeze dried microencapsulation method was used in five different combinations of chitosan (CH), Prunus cerasoides gum exudate (PG) and galactomannan as wall material with anthocyanin (ANS) as core material. The microencapsulated powders with different proportions of wall material showed encapsulation efficiency in the range of 90.51%–94.60%. Fourier-transform infrared spectroscopy confirmed the cross-linking interactions between ANS and wall materials. Enhanced thermal stability of the ANS with wall materials was indicated by thermogravimetric analysis. The stability of microcapsules and ANS was evaluated by spectrophotometric and liquid chromatographic methods at two conditions (4 °C and room temperature) during 90 days. The results revealed that ANS encapsulated with CH-PG/ANS (4/1) exhibited maximum retention of anthocyanins (72.88% and 60.02%) and enhanced the stability and antioxidant potential of anthocyanins.

壳聚糖-樱桃李胶分泌物对小檗花青素热性能、贮藏稳定性和抗氧化活性的影响

为保护小檗浆果中的花青素，在壳聚糖 (CH)、 Prunus cerasoides的五种不同组合中使用冷冻干燥微囊化方法胶分泌物（PG）和半乳甘露聚糖为壁材，花青素（ANS）为芯材。不同壁材比例的微胶囊化粉末的包封率在90.51%~94.60%之间。傅里叶变换红外光谱证实了 ANS 和壁材料之间的交联相互作用。热重分析表明 ANS 与壁材料的热稳定性增强。通过分光光度法和液相色谱法在两种条件（4°C 和室温）下 90 天评估微胶囊和 ANS 的稳定性。结果表明，用CH-PG/ANS（4/1）封装的ANS表现出最大的花青素保留率（72.88%和60.02%），并增强了花青素的稳定性和抗氧化潜力。
