黑醋栗(RibesnigrumL.)是在欧洲广泛种植的浆果灌木,用于生产果汁,果酱,果冻,和糖浆。除了浆果,黑醋栗的叶子和果渣,作为副产品,也被证明具有促进健康的作用。静态消化,模拟口腔,胃,和小肠消化,被应用,和黑醋栗叶,水果,并根据回收率指数评估了果渣和多酚的生物可及性。结果与样品类型有关,在水果的情况下,采收率指数呈现较高的值,表明黑醋栗的这一形态部分是生物最容易获得的。使用四种不同的方法评估了黑醋栗的抗氧化潜力,与水果和果渣相比,叶子被证明是一种重要而强大的抗氧化剂。使用体外诱导的脂质过氧化以及超氧化物和羟基阴离子的抑制潜力来评估抑制氧化过程的抵消潜力。抗氧化剂评估以及对生物和非生物自由基的抑制表明叶提取物是所研究的最强大的抗氧化剂。此外,结果证明,不仅水果,而且黑醋栗副产品(果渣和叶子)都是生物可获得的抗氧化剂的有希望的来源,对动物营养具有潜在的益处。
Blackcurrant (Ribes nigrum L.) is a berry bush widely cultivated in Europe for producing juices, jams, jellies, and syrups. In addition to berries,
blackcurrant leaves and pomace, as byproducts, have also been shown to have health-promoting effects. Static digestion, simulating oral, gastric, and small intestinal digestion, was applied, and
blackcurrant leaves, fruits, and pomace and the polyphenol bioaccessibility were evaluated in terms of recovery index. The results were related to sample type, and the recovery index presented higher values in the case of fruits, indicating this morphological part of blackcurrant as the most bioaccessible. The antioxidant potential of
blackcurrant was evaluated using four different methods, with the leaves proving to be a significant and powerful antioxidant compared to fruits and pomace. The counteracting potential of inhibiting the oxidation process was evaluated using in vitro-induced lipid peroxidation and the inhibition potential of superoxide and hydroxyl anions. The antioxidant evaluation and the inhibition of biological and non-biological radicals indicate the leaf extract is the most powerful antioxidant studied. Also, the results proved that not only fruits but also the
blackcurrant byproducts (pomace and leaves) are promising sources of bioaccessible antioxidants with potential benefits in animal nutrition.
