How are biogenic amines removed?
Biogenic amines are typically removed from foods through processes such as fermentation, heat treatment, and freezing. In certain cases, they can also be reduced by using additives or enzymes that break down the amines. Overall, proper food storage and processing techniques play a key role in managing biogenic amines levels.
Why do amines turn yellow?
Amines can turn yellow due to oxidation or degradation processes, forming colored products. This color change may be more prominent when amines are exposed to air, light, or heat over time. It's important to store amines properly in a dark, cool, and oxygen-free environment to prevent yellowing.
Do amines and nitrates cancel each other in the stomach?
Amines + Nitrates/Nitrites = carcinogenic nitrosamines
Why is diazotization not possible in aliphatic amines?
Bcoz alipatic amines require very low temperature like about -25 degrees celsius...which is difficult to maintain.....thats y its not posible to form diazonium salt with aliphatic amines...where as for aromatic amines its posible as temperature range is 0 - 5 degres..
What are the implications for primary and secondary amines in their reaction with ninhydrin?
Primary amines react with ninhydrin to produce a deep blue-purple color due to the formation of a colored complex, which is useful for detecting amino acids and peptides. Secondary amines also react, but typically yield a less intense color compared to primary amines. This difference in reactivity can be utilized in analytical chemistry to distinguish between primary and secondary amines in various samples. Tertiary amines do not react with ninhydrin, highlighting the specificity of this reaction in identifying amine types.

What rock comes after granite Is subjected to enough heat and pressure in the rock cycle?
When granite is subjected to enough heat and pressure, it becomes a metamorphic rock called gneiss.
Do earthquakes happen in Romania?
Yes, Romania is subjected to earthquakes.
What are amines known for in chemistry?
Amines are produced when a hydrogen atom in ammonia has been replaced by an alkyl or aryl group. Examples of amines are biogenic amines, amino acids and aniline.
Who won the battle of Amines?
German's won the battle of amines
Why is aliphatic amines stronger bases than aromatic amines?
Aliphatic amines are stronger bases than aromatic amines because the lone pair on the nitrogen atom in aliphatic amines is more available for donation due to the absence of resonance effects that stabilize the lone pair in aromatic amines. This makes aliphatic amines more likely to accept protons and act as bases.
What is the formation of slate?
when shale is subjected to heat and pressure, it can be metamorphosed into slate.
When heated with chloroform secondary amines and tertiary amines are?
Secondary amines produce N-alkyl-substituted formamides, while tertiary amines form N-alkyl-substituted chloroformamides when heated with chloroform.
Do amines contain oxygen?
Not necessarily. Amines contain nitrogen, but many do not contain oxygen.
If shale is subjected to heat and pressure what type of rock dose it form?
a rock
What s a metamorphic rock that is made from slate that has been subjected to heat and pressure?
phyllite
