摘要
研究了强脉冲光(IPL)处理不同电压(800 ~ 1600 V)和时间(10 ~ 240 s)对苹果和梨中蜡样芽孢杆菌孢子灭活的影响。结果表明，IPL处理对苹果和梨中蜡样芽孢杆菌孢子的灭活效果分别为2.35和2.94个对数单位。1600 V IPL处理240 s后，苹果和梨的温度分别升高2.6℃和4.7℃。颜色分析表明，1600v处理240s后，果实的L*值显著降低，a*值显著升高，而苹果和梨的b*值在240s后无显著变化。结果表明，通过IPL处理可有效灭活方便婴儿食品原料上的蜡样芽孢杆菌孢子，而不影响这些水果的品质。
Intense pulsed light treatment for inactivation of Bacillus cereus spores in fruits for convenience infant foods
This study aimed to assess the effects of intense pulsed light (IPL) treatment for the inactivation of Bacillus cereus spores in apples and pears for convenience infant foods by varying treatment voltage (800-1600 V) and time (10-240 s). The results of the study indicated that IPL treatment reduced the number of spores by up to 2.35 log units in apples and 2.94 log units in pears. Additionally, the temperature of apples and pears increased by 2.6 and 4.7℃, respectively, after IPL treatment at 1600 V for 240 s. Color analysis showed a significant decrease in L* values and an increase in a* values of the fruits treated with 1600 V for 240 s, but no significant change in b* values of apples for 240 s and pears for 120 s. These results demonstrate that B. cereus spores on convenient infant food ingredients can be effectively inactivated by IPL treatment without sacrificing the quality of these fruits.
