Effect of porcine plasma protein hydrolysates on long-term retrogradation of corn starch

Abstract The potential effect of porcine plasma protein hydrolysates (PPPH) on the long-term retrogradation of corn starch (CS) was investigated. The differential scanning calorimetry results showed that PPPH significantly reduced the retrogradation enthalpies (Δ H r) of CS ( P k ), and enhanced the Avrami exponent ( n ) ( P T 2 ) remarkably increased with increasing PPPH concentration during storage at 4 °C for 28 days ( P
