中文摘要: 该研究采用高温普鲁兰酶制备的莲子多孔淀粉吸附原花青素，负载量高达20.08 mg/g，与天然莲子淀粉相比，莲子多孔淀粉-原花青素复合材料的透明度提高6.79%，堆积密度降低0.1 g/cm3，糊化温度升高。紫外线对原花青素的影响明显，紫外线照射6h后，与未经吸附的原花青素相比，复合材料的1，1-二苯基-2-三硝基苯肼（1，1-diphenyl-2-picryl-hydrazyl radical，DPPH）自由基清除率变化较缓慢，衰减常数较低。体外缓释作用结果表明，复合材料可在胃液中稳定并在肠液中缓慢释放。
Abstract:Proanthocyanidins were adsorbed onto lotus seed porous starch prepared with thermotolerant pullulanase，achieving a loading capacity of20.08 mg/g. Compared with natural lotus seed starch，the lotus seed porous starch-proanthocyanidins composite material exhibited an increase of 6.79% in transparency，a reduction of0.1 g/cm3in bulk density，and a rise in gelatinization temperature. Ultraviolet （UV） exposure had a notable impact on proanthocyanidins. After 6 h of UV irradiation，the 1，1-diphenyl-2-picryl-hydrazyl （DPPH） scavenging rate of the composite material changed more slowly than that of the control，with a lower decay constant.The in vitro release experiments showed that the composite material remained stable in the gastric fluid and released slowly in the intestinal fluid.
