Though many people do not have the tyramine problem, but this amino acid can be induced by the intolerance of some allergic reactions. Eating foods containing tyramine can cause hives, water retention and health problems such as asthma, and migraine is the most common side effects. Because the tyramine is naturally formed in the process of aged and protein decomposition, and they are therefore the most commonly found in fermentation or a yeast food.
List Of Food Groups Rich in Tyramine
Cheese : All aged cheese contain tyramine, which is a byproduct of the aging process. Therefore, attention should be paid to any food that contains cheese, such as ricotta cheese and cream cheese etc.. without any aging process. Hence, it does not contain tyramine and safe for consumption. The tyramine content level depends on the processing of food and aging concern with the bacteria.
Meat and fish : Under normal circumstances, the fresh meat and fish contain only a small amount of tyramine. But long time storage (including refrigerated) can cause the decomposition of protein and increase the number of tyramine carnivorous. Smoking, age or fermented meat and fish contain large amounts of tyramine. Tyramine content is very high in hot dogs, processing of sandwich meat, bacon and ham.
Yeast : Although most commercial bread can be safe to eat, but the homemade yeast bread contains a large number of tyramine. In addition, many canned, frozen food processing also contain yeast, it is necessary to carefully check the label.
Beans : Certain beans will contain tyramine due to the decomposition of protein, such as Soy Milk miso, soy sauce, tofu, etc..
Vegetables and fruit : Overripe bananas, spinach and pickled cabbage usually contain large amounts of tyramine. So you should avoid all overripe and spoiled fruits.
Leftovers : Any leftover foods also goes in the process of formation of tyramine. Therefore, nutrition experts recommend eating freshly cooked food. Leftover food should not be kept for more than 2 to 3 days in the refrigerator.
Beverages : Beer, wine, whiskey and other liquors are rich in tyramine content. You must avoid the non-alcoholic beer. But it is safe to drink champagne, gin, vodka and Scotch whiskey, because of their low levels of tyramine.
- Alcoholic beers : 0.98 to 3.21 mg L-1.
- Nonalcoholic beers : 0.52 to 3.96mg L-1.
Additives : should carefully check processing, canned and frozen food ingredients label. They may contain some protein powder, which will increase the tyramine content. In addition, tender agent or canned juice contains large amounts of tyramine.
In addition, chocolate and coffee also has a small amount of tyramine. However, in the case of avocados food, the tyramine doesn’t affect adversely. and should limit the consumption of peanuts, Brazil nuts and coconut.
Biogenic amines in food: Effects of histamine and tyramine in the human.
8 ~ 40mg intake of histamine produces mild symptoms, if exceed 40mg produce moderate symptoms of poisoning, more than 100mg produce severe symptoms of poisoning. The tyramine over 100mg will cause a migraine.
1000mg • kg-1 biogenic amines in food harmful to human health and cause a great deal of harm.
Histamine, tyramine role, the presence of other biogenic amines enhance the adverse effects of histamine and tyramine. Therefore, it is difficult to determine a standard to measure the toxicity of biogenic amines.
Study through large amounts of data outbreak of histamine poisoning, determine the level of harmful effects of histamine in food: 500mg • kg-1; EU regulations Scombroid fish histamine content shall not exceed 100 mg • kg-1, other food shall not exceed 100mg • kg-1, histamine tyramine shall not exceed 100 ~ 800mg • kg-1;
