香芹酚纳米乳液结合ε-聚赖氨酸盐酸盐对冷鲜猪肉的保鲜效果
Effect of Carvacrol Nanoemulsion Combined with ε-Polylysine Hydrochloride on the Preservation of Chilled Pork
摘要
Abstract
This study aimed to investigate the preservation effect of carvacrol nanoemulsion(CN)combined with ε-polylysine hydrochloride(ε-PLH)on chilled pork.The optimum parameters for CN preparation were determined based on pseudo-ternary phase diagram,emulsion appearance,particle size,and particle size distribution.The effects of the combined application of CN and ε-PLH on the preservation of chilled pork were evaluated by determining the total bacterial count,Staphylococcus aureus count,pH,thiobarbituric acid reactive substances(TBARS)value,textural characteristics,and sensory quality.The results showed that CN,composed of 26.18%carvacrol,8.46%tween-80,2.82%anhydrous ethanol,62.54%ultrapure water by volume,had good stability,with a particle size of 41.91 nm,a polydispersion index of 0.23,and a zeta potential of-38.27 mV.After 8 days of storage at 4℃,the total viable count,S.aureus count,pH,and TBARS value of chilled pork treated with 122.50 µg/mL CN combined with 200.00 µg/mL ε-PLH were significantly lower than those in each single treatment group(P<0.05).Moreover,the sensory acceptability for odor,texture,and color was higher.Compared with the untreated group,the 122.50 μg/mL CN combined with 200.00 μg/mL ε-PLH treatment prolonged the shelf life of chilled pork to 8 days.This study demonstrated that CN combined with ε-PLH could effectively inhibit the growth and reproduction of microorganisms and reduce the changes of physicochemical indexes during cold storage,thus effectively delaying the spoilage of chilled pork.关键词
