Comparison of Yangguang- pork and normal chilled meat on eating quality and chemistry index

Yangguang- pork is a kind of chilled pork which came from specially fed pigs. Eating quality and chemistry index of Yangguang- pork and normal chilled meat were inverstigated. Results showed that the fat content of Yangguang- pork( 2.40%) was significantly higher( p < 0.05) than that of normal chilled meat( 1.50%),without differences( p > 0.05) on p H value and moisture content.Content of all amino acids but cysteine,Total amino acid( TAA),Essential amino acid and Semi- essential amino acid( EAA + HEAA),flavor amino acids in Yangguang- pork were higher than those in normal chilled meat.Compared to normal chilled meat,Yangguang- pork showed higher eating quality,especially on tenderness,water holding capacity( WHC) and juiciness.
