Examples
preparation example 1
[0058] Weigh 45kg of phosphate buffer solution with a pH of 7.0, 3kg of chicken protein peptide freeze-dried powder, 1kg of sucrose and 2kg of xylose in a reaction vessel, stir and mix, and collect the mixed solution;
[0059] (2) Take the mixed solution and heat it in an oil bath at 110°C, and keep it warm for 1000 minutes;
[0060] (3) Stand to cool to room temperature, dialyze and collect the dialysis product with a molecular weight of 2500Da, filter and freeze-dry to obtain sucrose-reducing sugar-protein peptide non-enzymatic browning reaction product 1.
preparation example 2
[0062] Weigh 47kg of phosphate buffer solution with a pH of 7.0, 4kg of chicken protein peptide freeze-dried powder, 2kg of sucrose and 2kg of xylose in a reaction container, stir and mix, and collect the mixed solution;
[0063] (2) Take the mixed solution and heat it in an oil bath at 115°C, and keep it warm for 110 minutes;
[0064] (3) Stand to cool to room temperature, dialyze and collect the dialyzed product with a molecular weight of 2750Da, filter and freeze-dry, and collect sucrose-reducing sugar-protein peptide non-enzymatic browning reaction product 2.
preparation example 3
[0066] Weigh 50kg of phosphate buffer solution with a pH of 7.0, 5kg of chicken protein peptide freeze-dried powder, 3kg of sucrose and 2kg of xylose in a reaction container, stir and mix, and collect the mixed solution;
[0067] (2) Take the mixed solution and heat it in an oil bath at 120°C, and keep it warm for 120 minutes;
