| FooDB Name | Maltol |
|---|
| Description | Found in chicory, roasted malt, breads, milk, heated butter, uncured smoked pork, cocoa, coffee, roasted barley, roasted peanuts, roasted filbert, soybean etc. Flavour enhancer and flavouring agent
Maltol is a naturally occurring organic compound that is used primarily as a flavor enhancer. It is found in the bark of larch tree, in pine needles, and in roasted malt (from which it gets its name). Because it has the odor of cotton candy and caramel, maltol is used to impart a sweet aroma to fragrances. Maltol's sweetness adds to the odor of freshly baked bread, and is used as a flavor enhancer (E number E636) in breads and cakes. Maltol is a biomarker for the consumption of soy beans and other soy products. |

| Anti convulsant | 52217 | An agent that reduces or prevents seizures, commonly used in managing epilepsy, neuropathic pain, and mood disorders, by stabilizing abnormal electrical activity in the brain. | DUKE | | Anti-fatigue | 52217 | An agent that reduces physical and mental exhaustion, enhancing endurance and vitality. It plays a biological role in regulating energy metabolism and mitigating oxidative stress. Therapeutically, anti-fatigue agents are used to manage chronic fatigue syndrome, improve athletic performance, and alleviate symptoms of anemia and other debilitating conditions. | DUKE | | Anti-oxidant | 22586 | An agent that neutralizes free radicals, reducing oxidative stress and cell damage. Its biological role involves protecting cells from harm, and it has therapeutic applications in managing chronic diseases, such as cancer, diabetes, and neurodegenerative disorders, with key medical uses including anti-aging, anti-inflammatory, and cardio protective effects. | DUKE | | Cancer preventive | 35610 | An agent that inhibits the development and progression of cancer, reducing tumor formation and growth. It plays a biological role in blocking carcinogenic pathways, and has therapeutic applications in chemoprevention. Key medical uses include reducing the risk of cancer in high-risk individuals and preventing cancer recurrence. | DUKE | | Central nervous system sedative | 35470 | An agent that calms the brain and nervous system, reducing anxiety and agitation. Therapeutically, it's used to manage insomnia, seizures, and restlessness, and as an adjunct for anesthesia and medical procedures, promoting relaxation and reducing stress. | DUKE | | Name | 48318 | flavor | DUKE | | Fungistat | | An agent that inhibits fungal growth, used to prevent fungal infections, commonly applied in therapeutic applications such as treating skin and nail infections, and managing fungal diseases in immunocompromised patients. | DUKE | | Motor depressant | | An agent that reduces the normal functioning level of motor neurons, mainly in voluntary muscles, used to treat conditions such as muscle spasms, seizures, and anxiety disorders, promoting relaxation and relieving symptoms. | DUKE | | Pesticide | 25944 | An agent that kills or repels pests, playing a biological role in controlling insect, weed, and fungal populations. Therapeutically, pesticides have limited applications, but some are used to treat ectoparasitic infestations, such as lice and scabies. Key medical uses include topical treatments for head lice and scabies, highlighting their role in managing parasitic infections. | DUKE | | Sedative | 35717 | An agent that calms nervous activity, reducing anxiety and inducing relaxation. Its biological role is to slow down brain function, promoting sleep and relieving stress. Therapeutically, sedatives are used to manage insomnia, anxiety disorders, and seizures, as well as to prepare patients for medical procedures. | DUKE | | Sweetener | 50505 | A substance that adds sweetness to food and beverages, often used as a sugar substitute. Its biological role is to stimulate taste receptors, while its therapeutic applications include managing calorie intake and blood sugar levels. Key medical uses include treating diabetes and obesity, as well as reducing tooth decay risk. | DUKE |
