Significant differences (P < 0.05) were found between the survival rates of Salmonella enterica and Escherichia coli O157:H7 in peanut butter with different formulations and water activity. High carbohydrate content in peanut butter and low incubation temperature resulted in higher levels of bacterial survival during storage but lower levels of bacterial resistance to heat treatment.
在不同配方和水分活度的花生酱中,发现沙门氏菌和大肠杆菌 O157:H7 的存活率有显著差异(P < 0.05)。花生酱中高碳水化合物含量和低培养温度导致储存过程中细菌存活率较高,但细菌对热处理的抵抗力较低。
