Amine groups such as free amino acids and protein as well as carbonyl compounds such as reducing sugars like fructose,  glucose, maltose or lactose.

 

Longer baking time or higher baking temperature,

 

Other than flavour generation, Maillard reactions can generate compounds with antioxidant activity, such as reactive oxygen species, scavenging activity or metal‐chelating activity. Melanoidins are a group of anionic and colored compounds commonly generated during the Maillard reaction and exhibit biological effects such as antioxidant, antiradical or metal chelating properties have been studied in vitro. A study by Lindenmeier, Faist, & Hofmann (2002) showed that melanoidins could also induce chemo-preventive enzymes in the cell culture model system of the human intestinal cell. 

There are flavour precursors for maillard reaction such as amine groups which is from amino acids and proteins, and carbonyl compounds which is from reducing sugar such as fructose, glucose, maltose, or lactose

 

b.     What conditions favour Maillard reactions during baking?

During baking, maillard reactions favour high temperature, long baking time, high sugar mount and presence of amino acid

 

c.      Other than flavour generation, Maillard reactions can generate compounds with antioxidant activity, what does it mean?

Besides flavour compounds, maillard reactions generate other compounds with antioxidant capabilities. This compound is reactive oxygen species scavenging activity or metal-chelating activity. Specifically, maillard reactions can generate Melanoidins which has antioxidant activity by inducing chemo-preventive ensymes in cell culture model system of human intestinal cell.

The flavour precursors for Maillard reactions are amine groups, usually usually from amino acids and proteins, and carbonyl compounds, generally from reducing sugars, such as fructose, glucose, maltose or lactose 

 

b. What conditions favour Maillard reactions during baking?

The condition that favour Maillard reactions during baking are high temperatures, a long baking time, a high amount of sugar, along with the presence of amino acid

c. Other than flavour generation, Maillard reactions can generate compounds with antioxidant activity, what does it mean?

 
Maillard reactions can also induce the formation of compounds with antioxidant activity, such as reactive oxygen species scavenging activity or metal‐chelating activity The biological effects of melanoidins from foods, especially antioxidant, antiradical, or metal chelating properties have been studied in vitro. And according to research done by Lindenmeier, Faist, & Hofmann, (2002), melanoidins could also induce chemo-preventive enzymes in cell culture model.

2.      What conditions favour Maillard reactions during baking?

 

During baking, maillard reactions favour high temperature, long baking time, high sugar mount and presence of amino acid.

3.      Other than flavour generation, Maillard reactions can generate compounds with antioxidant activity, what does it mean? 

 

Maillard reaction induce the formation of compounds with antioxidant activity, such as reactive oxygen species scavenging activity or metal‐chelating activity. Melanoidins could also induce chemo-preventive enzymes in cell culture model system of human intestinal cell.

 

The flavor precursors responsible for Maillard reaction are amine groups from amino acids and proteins, as well as carbonyl groups, generally from reducing sugars, such as fructose, glucose, maltose or lactose.

 

b.       What conditions favour Maillard reactions during baking?

 

Conditions such as high temperatures in food processes such as baking, roasting. Storage for prolonged periods of time is another condition.

  

c.       Other than flavour generation, Maillard reactions can generate compounds with antioxidant activity, what does it mean?

 

Maillard reaction not only generates flavor compounds but also induce the formation of compounds with antioxidant activity, such as reactive oxygen species scavenging activity or metal‐chelating activity called Melanoidins. They are a group of anionic and colored compounds generated during the Maillard reaction.
