Betanin, or beetroot red, is a red glycosidic food dye obtained from beets; its aglycone, obtained by hydrolyzing the glucose molecule, is betanidin. As a food additive , its E number is E162. [ 1 ]

甜菜根红素(Betanin)在商業上用作天然食用色素。 它會導致某些無法分解的人出現甜菜尿（Beeturia, 紅色尿液）和紅色糞便。 自從通過體外In vitro方法將甜菜素鑑定為抗氧化劑 [18] ， 可以防止低密度脂蛋白氧化 [19] 以來，食品工業對甜菜素的興趣不斷增長。

甜菜苷是从甜菜根中提取的，是甜菜中的主要色素，可溶于水，适于作各种食品的着色剂。但是，由于它在水溶液中对温度的稳定性差，所以在应用上受到了限制。在有氧气存在的条件下，甜菜苷极易发生降解。在缺氧的条件下，降解就减慢。然而，甜菜苷在水溶液中的降解是可逆的，其再 …

Betanin is a scavenger of reactive oxygen species and exhibits gene-regulatory activity partly via nuclear factor (erythroid-derived 2)-like 2-(Nrf2) dependent signaling pathways. Betanin may induce phase II enzymes and antioxidant defense mechanisms.

甜菜碱是一种生物碱，化学名称为N,N,N-三甲基甘氨酸，化学结构与氨基酸相似，属季铵碱类物质，分子式为C5H11NO2。甜菜碱广泛存在于动植物体内。在植物中，枸杞、豆科植物均含有甜菜碱。甜菜的糖蜜是甜菜碱的主要来源。在动物中，章鱼、墨鱼、虾等软体动物，以及脊椎动物（包括 …

Betanin, obtained from beetroot, particularly Beetroot Red, is an approved red food colorant and is widely used in the food industry to color food products and beverages in pink, red, or purple colors.

甜菜苷（betanin）是最简单的甜菜红素，其R3位置连接着β-葡萄糖，R4位连接一个氢原子，它的分子量为550 g/mol。 甜菜红素是次生代谢产物，甜菜红素的合成通路开始于L-酪氨酸。

2020年1月2日 · Nowadays, the demand for eco-friendly/nontoxic natural colorants is growing as an essential alternative to potentially harmful synthetic dyes. Betanin is the chief red pigment of beetroot, and it is the only betalain approved for use in food and pharmaceutical products as a natural red colorant.
