hydroxybenzoic acid amides of benzylamines were synthesized and evaluated as masking agents toward bitterness of caffeine by sensory methods. The closest structural relatives of homoeriodictyol, the hydroxybenzoic acid vanillylamides 5-9, were the most active and were able to reduce the bitterness of a 500 mg L(-1) caffeine solution by about 30% at a concentration of 100 mg L(-1). 2,4-Dihydroxybenzoic acid vanillylamide
从已知的来自苦艾草的苦味掩盖黄烷酮香茅醇和高香茅醇开始,合成了一些结构上相关的苄基胺的羟基苯甲酰胺,并通过感官方法评价了其作为咖啡因苦味的掩盖剂。最高间苯三酚的结构亲戚,羟基苯甲酸vanillylamides 5-9,是最活跃的,能够在浓度为100 mg L(-)的情况下将500 mg L(-1)咖啡因溶液的苦味降低约30%。 1)。2,4-二羟基苯甲酸香草酰胺7表现出明显的剂量依赖性活性,可抑制5至500 mg L(-1)中的咖啡因苦味。另外,可以减少奎宁和水杨酸的苦味,但不能减少苦肽N1-亮氨酰-1-色氨酸的苦味。高雌三醇和酰胺7的组合显示没有协同或拮抗活性的变化。模型化合物7的结果表明,迄今未知的黄烷酮和新酰胺的掩盖机理可能相同。将来,新的酰胺可能会替代昂贵的黄烷酮,以创造掩盖药品或食品苦味的调味剂溶液。
