Professor Zhang Xiaoming and Professor He Qixuan: The merade reaction intermediate of pea protein hydrolysing products improves the flavor of intermediates

Highlights:
the variable temperature of the merade reaction may indicate the formation of the Merad reaction intermediate (MRI);
Merad reaction reduces the bitter taste of pea protein hydrolysate products; mrI of
pea protein hydrolysate products has better flavor enhancement; MRI of
pea protein hydrolysates increases salt salinity in salt solutions; and MRI of
pea protein hydrolytes promotes salivary aldehyde solidone secretion.

of the Department of Food Science at Rutgers University in the United States, using pea protein hydrolyzing products as the main raw material, prepared Merard reaction intermediates (MRI) at low temperatures (80 degrees C), the reaction time is determined by the temperature change Merad reaction. Electronic tongue and sensory assessments are used to analyze the taste of pea protein hydrolysed products and MRIs. Both results showed that the hydrolysed products of pea protein had less bitter taste but increased freshness through the Merad reaction. Freshness and saltiness were positively related to the concentration of MRI. Even at an MRI concentration of 0.1% (w / w), MRI can reduce NaCl content by 20% without reducing saltiness, which may be an important alternative to salt reduction. On the other hand, the increase in MRIs promotes the secretion of aldosterone in saliva, which may enhance human perception of saltiness.
