BACKGROUND Ginkgo biloba seeds are used as a functional food across Asia. However, the presence of toxic compounds has dwindled its application. In this study, freeze-drying, infrared drying, hot-air drying and pulsed-vacuum drying were used to dry GBS. A comprehensive analysis was performed on their product quality, antioxidant activities, bioactive and toxic components. RESULTS Results showed drying methods had a significant influence on product quality with freeze-drying being superior due to the minute microstructural damage, followed by infrared drying, and pulsed-vacuum drying. Infrared-dried product possessed the strongest antioxidant activities, and higher bioactive compounds content than hot-air drying and pulsed-vacuum drying. Toxic compounds in fresh ginkgo biloba seeds (Ginkgotoxin, Ginkgolic acid and cyanide) reduced drastically by drying. Ginkgotoxin reduced by 4 folds, and the content of acrylamide, ginkgolic acid and cyanide in the dried ginkgo biloba seeds reduced to the scope of safety. Amongst the four drying methods, infrared drying had the shortest drying time, and its product showed higher quality and bioactive compounds content, and stronger antioxidant activities. CONCLUSION These findings will offer a piece of salient information for selecting the drying method during the processing of ginkgo seeds. Infrared drying could be considered as a multiple-effect drying method in the processing of ginkgo seeds. This article is protected by copyright. All rights reserved.

不同干燥方式对银杏种子产品品质、活性及毒性成分的影响

背景银杏种子在亚洲被用作功能性食品。然而,有毒化合物的存在减少了其应用。在本研究中,冷冻干燥、红外干燥、热风干燥和脉冲真空干燥用于干燥 GBS。对其产品质量、抗氧化活性、生物活性和毒性成分进行了综合分析。结果 结果表明,干燥方法对产品质量有显着影响,冷冻干燥因微观结构损伤小而优越,其次是红外干燥和脉冲真空干燥。红外干燥产品的抗氧化活性最强,生物活性化合物含量高于热风干燥和脉冲真空干燥。新鲜银杏种子中的有毒化合物(Ginkgotoxin,银杏酸和氰化物)通过干燥急剧减少。银杏毒素降低4倍,银杏干种子中丙烯酰胺、银杏酸、氰化物含量降低至安全范围。在四种干燥方式中,红外线干燥的干燥时间最短,其产品质量和生物活性化合物含量更高,抗氧化活性更强。结论这些发现将为银杏种子加工过程中干燥方法的选择提供重要信息。红外干燥可以被认为是银杏种子加工过程中的一种多效干燥方法。本文受版权保护。版权所有。干银杏种子中的银杏酸和氰化物降低到安全范围内。在四种干燥方式中,红外线干燥的干燥时间最短,其产品质量和生物活性化合物含量更高,抗氧化活性更强。结论这些发现将为银杏种子加工过程中干燥方法的选择提供重要信息。红外干燥可以被认为是银杏种子加工过程中的一种多效干燥方法。本文受版权保护。版权所有。干银杏种子中的银杏酸和氰化物降低到安全范围内。在四种干燥方式中,红外线干燥的干燥时间最短,其产品质量和生物活性化合物含量更高,抗氧化活性更强。结论这些发现将为银杏种子加工过程中干燥方法的选择提供重要信息。红外干燥可以被认为是银杏种子加工过程中的一种多效干燥方法。本文受版权保护。版权所有。结论这些发现将为银杏种子加工过程中干燥方法的选择提供重要信息。红外干燥可以被认为是银杏种子加工过程中的一种多效干燥方法。本文受版权保护。版权所有。结论这些发现将为银杏种子加工过程中干燥方法的选择提供重要信息。红外干燥可以被认为是银杏种子加工过程中的一种多效干燥方法。本文受版权保护。版权所有。
