Selection of promissory crops of wild cherry-type tomatoes using physicochemical parameters and antioxidant contents

ABSTRACT Tomato is considered a fruit with a high food demand across the world due to its high antioxidant capacity. Lycopene content in tomato has been widely studied, particularly in cherry-type tomatoes which are considered a high source of lycopene for humans. The aim of this study was to analyze the differences in terms of concentration and variation of diverse physicochemical parameters of quality (acidity, vitamin C, pH, °Brix, color coordinates L*, a* and b*) and, antioxidants like ?-carotene and lycopene in 11 accessions of cherry-type tomatoes, considering the advantages of antioxidants for human health. Multicriteria analysis and other tests showed substantial differences among the accessions. IAC401 was associated with the best physicochemical characteristics of a promissory cherry-type tomato for cultivation due to its association with functional food, followed by IAC426R and IAC1624. This study allowed an innovative association of physicochemical characteristics and antioxidant contents of cherry-type tomatoes through multicriteria analyses which enable the analysis, elimination, and proposal of promising accessions for their use in future crops which will promote the best intrinsic features of tomato to be used in the studied region. In this case accessions with the highest scores offer not only optimum amounts of antioxidants and highest levels of organic acids and sugars.

摘要：番茄因具备优异的抗氧化能力，在全球范围内拥有极高的食品需求量，是广受青睐的食用果实。番茄中的番茄红素含量已得到广泛研究，其中樱桃番茄（cherry-type tomato）被认为是人类获取番茄红素的优质来源之一，相关研究尤为聚焦该品类。本研究旨在结合抗氧化物质对人体健康的益处，分析11份樱桃番茄种质资源的各项品质理化参数，包括酸度、维生素C、pH值、白利糖度（°Brix）、颜色坐标L*、a*和b*，以及β-胡萝卜素和番茄红素等抗氧化物质的浓度差异与变化规律。多准则分析及其他检测结果显示，不同种质资源间存在显著差异。其中IAC401具备最优的理化特性，是极具种植潜力的樱桃番茄种质资源，因其适配功能性食品开发需求，后续依次为IAC426R与IAC1624。本研究通过多准则分析，创新性地关联了樱桃番茄的理化特性与抗氧化物质含量，该方法可用于分析、筛选并推荐具备应用潜力的种质资源，用于未来的番茄种植，从而在研究区域内推广展现最优内在品质的番茄品种。在此研究框架下，得分最高的种质资源不仅拥有最优的抗氧化物质含量，还具备最高水平的有机酸与糖分。
