ABSTRACT
Microbial cross-contamination in the food production and processing environment is one of the major factors of food contamination and foodborne illness. The use of antimicrobial textiles can be a measure to reduce the bioburden in food production settings. However, application of synthetic antimicrobial agents such as silver, copper, titanium, and zinc in food systems is limited due to issues of toxicity. Thus, this study aimed to develop a textile with natural antimicrobial finishing that meets American Association of Textiles Chemists and Colorists (AATCC) standard. The textile samples were finished with the ethanolic extract of Parkia speciosa. The extract was tested on food borne pathogens and exhibited significant inhibitory activity against all the test microorganisms with minimum inhibitory concentration ranged from 0.32 to 1.25 mg/mL. Gas chromatography-mass spectrometry analysis showed that 2-[2-(2-ethoxyethoxy)ethoxy]ethyl acetate is the main bioactive constituents of the extract. The finished textile showed excellent antimicrobial efficacy with growth reduction of 90% on Hohenstein Challenge Test. The wash durability of the finished textile was found good even after 30 washes with commercial detergent. Finally, the bioburden test of the developed textile in the industrial scale food-processing setting showed that it is effective in preventing the microbial contamination.
摘要
食品生产加工环境中的微生物交叉污染是造成食品污染和食源性疾病的主要因素之一. 抗菌纺织品的使用可以作为减少食品生产环境中生物污染的一种措施. 然而，由于毒性问题，银、铜、钛和锌等合成抗菌剂在食品系统中的应用受到限制. 因此，本研究旨在开发一种符合美国纺织品化学家和染色师协会(AATCC)标准的天然抗菌整理纺织品. 纺织样品用美丽球花豆乙醇提取完. 提取液对食源性致病菌均有明显的抑制活性，最低抑菌浓度为0.32 ~ 1.25 mg/mL. 气相色谱-质谱分析表明，2-[2-(2-乙氧基)乙氧基]乙酸乙酯是该提取物的主要生物活性成分. 经霍亨斯坦氏挑战试验，抗菌效果良好，生长速度降低90%. 经30次商用洗涤剂洗涤后，织物的耐洗性仍然良好. 最后，在工业规模的食品加工环境中对研制的纺织品进行了生物负荷试验，结果表明，该方法能有效地防止微生物污染.
