Commercial plain low fat yogurt was mixed with fruit jelly and corn syrup and processed by mild heat treatment at 60C for 30 s and 30 kV/cm electric field strength for 32 mus total treatment time using OSU-2C pilot plant scale PEF system. Control and processed products were aseptically packaged and stored at 4 and 22C. Mild heat combined with PEF treatment significantly decreased the total viable aerobic bacteria and total mold and yeast of yogurt-based products during storage at both 4 and 22C (P less than or equal to 0.05). Mild heat treatment alone without any PEF treatment did not prevent the growth of microorganisms in yogurt-based products. Sensory evaluation indicated that there was no significant difference between the control and processed products (P :5 0.05). Color, pH and degreesBrix were not significantly affected by mild heat and PEF processing conditions.eninfo:eu-repo/semantics/openAccessOrange JuiceNonthermal PasteurizationPilot-PlantShelf-LifeMicroorganismsQualityPreservationGrowthYeastsArticle28316117810.1111/j.1745-4549.2004.tb00818.x2-s2.0-6944246288Q2WOS:000224162900001Q4
