Summary of the technology
The invention relates to a method for obtaining an enzymatic hydrolysate with dipeptidyl peptidase IV (DPP-IV) inhibitory activity, antihyperglycemic effect and inducer of glucagon-like peptide 1 (GLP-1) secretion from animal by-products, particularly chicken feet.
Description of the technology
The bioactive hydrosylate is characterized through the identification of peptides that it contains. Bioactivity of identified peptides has been determined too. The invention also relates to the use of the obtained hydrosilate in the treatment and/or prevention of diabetes, and the pharmacological use of the peptides containing the hydrolysate.
The enzymatic hydrolysate comprises griding chicken feet and lyophilizing to obtain a powder material having a particle size <2 mm; adjunsting an aqueous solution of this powder to a pH different from the pH of the starting powder by a value of 4 and heating between 30 and 120ºC for between 10 and 120 minutes; cooling the preceding solution to a temperature between 20 and 55°C and performing enzymatic hydrolysis for a time between 1 and 24 h with selected enzymes, evaluating and selecting the DPP-IV inhibitory activity. Antihiperglycemic effect was evaluated in the selected hydrolysate using a rat model with glucose intolerance and normoglycaemic rats. GLP-1 secretory activity of the hydrolysate was determined too.
