The effect of liposome-encapsulated nisin and bacteriocin-like substance (BLS) P34 to control the growth of Minas frescal cheese Listeria monocytogenesin has been investigated. Nisin and BLS P34 was encapsulated in a partially purify soybean phosphatidylcholine (PC-1) and PC-1-cholesterol (7:3) liposome. PC-1 nanovesicles before being featured. PC-1-packaging and nisin cholesterol BLS P34, respectively, 218 nm and 158 nm diameter, zeta potential in mV and mV 53 64, and the efficiency of the traps 88.9% and 100%. All treatments reduced the population of ofL. monocytogenescompared to control in 21 on the archives of Minas frescal cheese at 7° c. However, nisin and BLS P34 encapsulated in liposome PC-1-cholesterol is less effective in controllingL. monocytogenesgrowth vs. free 1 PC-bacteriocins and liposome-encapsulated. The highest inhibition effect was observed for nisin and BLS P34 encapsulated in liposome PC-1 after 10 days of storage products. The encapsulated in liposome of bacteriocins partially purified soy phosphatidylcholine can is a promising technology for the control of communicable diseases in the cheese.
