Delicious peptide

Beefy meaty peptide (BMP), also known as delicious peptide Enhances meat flavour. Octapeptide of the sequence Ly s-Gly-Asp-Glu-Glu- Ser-Leu-Ala. 

Synthesis of delicious peptide fragments catalyzed by immobilized proteases. 

The delicious peptide Lys-Gly-Asp-Glu-Glu-Ser-Leu-Ala, is an octapeptide which was isolated from the gravy of beef and its primary structure was proposed in 1978 (3). It possesses a taste profile umami/sour... 

Three fragments of the delicious peptide sequence lysine-glycine, serine-leucine-alanine and aspartic acid-glutamic acid-glutamic acid possess separately umami/salty, bitter and sour taste respectively but mixtures or combinations of them produce a similar taste of that corresponding to the complete octapeptide. The synthesis of CBZ-Lys-Gly-OMe and CBZ-Ser-Leu-OMe were carried out using immobilized trypsin and thermolysin. We have studied the influence of reaction medium (pH, temperature and substrate concentration) on the yield and initial reaction rate of synthesis.

The bitter peptide BPI a 114, isolated by Okai et al.239 > from casein hydrolysates, and delicious tasting peptides from fish proteins, will undoubtedly achieve practical importance in the food industry.
