Inhibition of foodborne bacterial pathogens in meat products using bioplastic with Ceasalpinia sappan heartwood crude extract
Main Article Content
Abstract
The bioplastic packaging is found to be inhibited the growth of bacteria causing spoilage of meat products. The result showed antibacterial activity of the crude extract of C. sappan heartwood. The results showed that the MIC values for E. coli, B. cereus and S. aureus were 1,875 mg/ml. In addition, the MBC values for E. coli and S. aureus were found to be 7,500 mg/ml but the MBC values for B. cereus were found to be more than 60,000 mg/ml. The result indicated that the inhibition zone diameter for bioplastics from corn starch and C. sappan heartwood crude extract inhibited E. coli, B. cereus and S. aureus were 5.4, 10.4 and 13.4, respectively. Therefore, bioplastic and crude extract of C. sappen heartwood could develop into packaging to prolong the meat product spoilage.
