| Abstract: | Bicinchoninic acid（BCA） method for rapid field detection of protein residues on food processing equipment was set up.Detection Limit,interference factors and practical application of BCA method were analyzed with the detection limit test,reaction time test,interference test and field application test on swab.BCA method can detect over 50μg protein on swab.Three kinds reducing sugar of 5000μg,less than 2μg vitamin C and 5μg vitamin B1 did not interfere testing results.The BCA method was simple,visible and of low detection limit.It was a good method for rapid field detection of protein residues on food processing equipment. |
