Huanglongbing (HLB) disease has reduced orange yield and flavor quality in Florida. Orange juice (OJ) and peel molasses (PM) compounds are "from the named fruit" (FTNF) and were tested for their effects on HLB-affected OJ taste. These and other "target" compounds, reportedly found in citrus, were spiked into off-flavored, HLB-affected reference juices. The spiked juice was evaluated by a sensory panel in comparison with unspiked juice for "sweetness", "sourness", "bitterness", "astringency", and "aftertaste". Of the target compounds, feruloyl putrescine, taxifolin, and neodiosmin most effectively reduced "bitterness", feruloyl putrescine reduced "astringency" and "aftertaste", while feruloyl putrescine and neodiosmin enhanced perceived "sweetness", perhaps due to reduced bitterness. OJ and PM fractions containing reported bitter limonoids, hydroxycinnamates, hesperidin, and/or polymethoxylated flavones enhanced "sourness', "bitterness", "astringency", and "aftertaste", and/or suppressed perceived "sweetness" (perhaps due to enhanced bitterness). Other fractions, containing feruloyl putrescine and/or vicenin-2 enhanced "sweetness" and reduced "bitterness", "sourness", "astringency", and/or "aftertaste". These potentially FTNF compounds may be useful for management of HLB-affected OJ juice flavor.

使用天然柑橘类非挥发性化合物缓解黄龙病影响的橙汁中的异味。

黄龙病(HLB)病降低了佛罗里达州的橙子产量和风味品质。橙汁(OJ)和果皮糖蜜(PM)化合物“来自指定的水果”(FTNF),并测试了它们对HLB影响的OJ口味的影响。据报道,在柑橘中发现的这些和其他“目标”化合物被掺入异味,受HLB影响的参比汁中。通过加感官小组将加标的汁液与未加标的汁液进行“甜度”,“酸味”,“苦味”,“涩味”和“余味”比较。在目标化合物中,阿魏酰腐胺,taxofolin和新恶臭素最有效地降低了“苦味”,阿魏酰腐胺减少了“涩味”和“余味”,而阿魏酰腐胺和新恶臭素则增强了“感知力”。“甜味”,可能是由于降低了的苦味。OJ和PM馏分中含有已报道的苦柠檬苦素,羟基肉桂酸酯,橙皮苷和/或聚甲氧基黄酮,可增强“酸味”,“苦味”,“涩味”和“余味”,和/或抑制感知“甜”(可能是由于苦味增强)。含有阿魏酰腐胺和/或维特宁2的其他馏分增强了“甜味”并减少了“苦味”,“酸味”,“涩味”和/或“余味”。这些潜在的FTNF化合物可用于管理受HLB影响的OJ汁液风味。酸”,“苦味”,“涩味”和“余味”,和/或抑制感知到的“甜味”(可能是由于苦味增强)。含有阿魏酰腐胺和/或维特宁2的其他馏分增强了“甜味”并减少了“苦味”,“酸味”,“涩味”和/或“余味”。这些潜在的FTNF化合物可用于管理受HLB影响的OJ汁液风味。酸”,“苦味”,“涩味”和“余味”,和/或抑制感知到的“甜味”(可能是由于苦味增强)。含有阿魏酰腐胺和/或维特宁2的其他馏分增强了“甜味”并减少了“苦味”,“酸味”,“涩味”和/或“余味”。这些潜在的FTNF化合物可用于管理受HLB影响的OJ汁液风味。
