摘要
野生浆果已被用于传统医学和营养,但即使在今天,它们也越来越多地被用作维生素、矿物质和生物活性成分的来源。消费者对健康生活方式的意识增强,导致功能食品市场的扩大,重点是浆果产品。因此,消费者对营养食品和饮料的兴趣越来越大,包括野生浆果类水果。为了满足消费者日益增长的需求,浆果越来越多地用于潜在的新功能产品的创造和配方。本研究以桑树(Sambucus nigra L.)和桑葚(Morus nigra L.)为原料,制备了富含瓜拉那种子干提取物的冷压果汁。研究了其营养价值、矿物质成分以及生物学和药理学潜力。分析结果表明,主要矿质元素为钾(接骨木为4398.80 mg/L,桑树为3582.11 mg/L)。所分析的果汁具有丰富的总酚类化合物来源(接骨木261.51 mg GAE/L,桑葚129.36 mg GAE/L)。-通过生物药理学研究,确定这些野生植物的汁液是一种非常强的还原剂,特别是对Cu2+离子,而在降低过多的酶活性方面,对酪氨酸酶的抑制效果最好(接骨木98.39 mg KAE/L,桑树78.99 mg KAE/L)。
Chemical composition and biopotential of mother juices of elderberry and mulberry enriched with guarana extract
Wild-growing berry fruits have been used in traditional medicine and nutrition, but even today they are increasingly used as a source of vitamins, minerals, and bioactive ingredients. Increased consumer awareness of healthy lifestyles has led to the expansion of the functional food market, focusing on berry products. Therefore, consumers' interest in nutritious foods and beverages, including wild-growing berry fruits become greater. In order to respond to the enhanced demands of consumers, berries are increasingly used for the creation and formulation of potentially new functional products. In this work, the plant species Sambucus nigra L. and Morus nigra L. were used to obtaining cold-pressing juices which are enriched with dry extract of guarana seeds. Nutritional values, mineral composition, as well as biological and pharmacological potential were examined. The results of the analysis showed that the dominant mineral was K (for elderberry 4398.80 mg/L and for mulberry 3582.11 mg/L). The analysed juices were characterized as a rich source of total phenolic compounds (for elderberry 261.51 mg GAE/L, for mulberry 129.36 mg GAE/L). - By examining the bio-pharmacological potential, it was determined that the juices of these wild plant species were a very strong reducing agents, especially towards the Cu2+ ion, while in reducing excessive enzyme activity, the best result was achieved in the inhibition of the enzyme tyrosinase (for elderberry 98.39 mg KAE/L, for mulberry 78.99 mg KAE/L).
