为了满足日益增长的健康意识消费者群体，越来越多的营养和健康声明被用于食品。然而，只有极少数食品成分，包括植物甾醇，被指定为批准的健康声明（欧洲委员会和食品和药物管理局）。植物甾醇是那些有限的批准化合物名单的一部分，因为它们具有降低胆固醇的特性，但也因其抗炎和抗癌特性而受到赞扬。尽管这一无可争议的声誉，直接的定量数据仍然缺乏天然存在的（共轭）植物甾醇饮料。本研究旨在通过将经过验证的提取和UPLC-MS/MS检测方法应用于各种日常植物饮料来填补这一空白。- 谷甾醇-β-d-葡萄糖苷（BSSG）是迄今为止研究的所有饮料中含量最高的甾醇，在植物基牛奶替代品和新鲜果汁中的浓度高达60-90 mg/100 mL。麦角甾醇（维生素D-2原）可以在啤酒中发现（0.8-6.1 μ g/100 mL，来自酵母），偶尔也可以在果汁中发现（17-29 μ g/100 mL）。总的来说，结果表明，水溶性甾醇共轭物的浓度被大大低估，特定的植物饮料可以是这些植物甾醇的良好的低脂来源。
To address the ever-growing group of health-conscious consumers, more and more nutritional and health claims are being used on food products. Nevertheless, only very few food constituents, including plant sterols, have been appointed an approved health claim (European Commission and Food and Drugs Administration). Plant sterols are part of those limited lists of approved compounds for their cholesterol-lowering properties but have been praised for their anti-inflammatory and anti-carcinogenic properties as well. Despite this indisputable reputation, direct quantitative data is still lacking for naturally present (conjugated) plant sterols in beverages. This study aimed to fill this gap by applying a validated extraction and UPLC-MS/MS detection method to a diverse range of everyday plant-based beverages. -sitosterol--d-glucoside (BSSG) showed to be by far the most abundant sterol in all beverages studied, with concentrations up to 60-90 mg per 100 mL in plant-based milk alternatives and fresh fruit juices. Ergosterol (provitamin D-2) could be found in beers (0.8-6.1 mu g per 100 mL, from the yeast) and occasionally in juices (17-29 mu g per 100 mL). Overall, the results demonstrated that the concentrations of water-soluble sterol conjugates have been underestimated significantly and that specific plant-based beverages can be good, low-fat sources of these plant sterols.
