Abstract

The aim of this study was to investigate the use of Arbutus unedo L. fruits for the production of functional foods by three-dimensional printing (3DP). First, the biological activity of the fruits was investigated in vitro, followed by 3DP with different starch types and proportions using two 3DP programs. All 3DP samples were characterized for their bioactive, antioxidant, physicochemical and rheological properties. In terms of biological activity, the recommended daily dose of polyphenols from the aqueous extract of A. unedo can protect the integrity of DNA. Moreover, it could be useful as an antimicrobial agent. All 3DP parameters significantly affected bioactive compounds and antioxidant capacity. The 3DP products were found to be a good source of polyphenols (632.60 mg/100 g), among which condensed tannins were predominant (42 %). In conclusion, the fruits of A. unedo should be considered as a sustainable resource for the production of innovative functional foods with 3DP.

摘要

本研究的目的是通过三维打印（3DP）研究杨梅果实用于生产功能性食品的情况。首先，对果实的生物活性进行了体外研究，随后使用两个3DP程序，采用不同类型和比例的淀粉进行三维打印。对所有3DP样品的生物活性、抗氧化、物理化学和流变学特性进行了表征。在生物活性方面，来自杨梅水提取物的多酚推荐日剂量可保护DNA的完整性。此外，它可用作抗菌剂。所有3DP参数均显著影响生物活性化合物和抗氧化能力。发现3DP产品是多酚的良好来源（632.60毫克/100克），其中缩合单宁占主导（42%）。总之，杨梅果实应被视为通过3DP生产创新功能性食品的可持续资源。
