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食品污染和食源性疾病的主要因素之一。使用抗菌纺织品可以作为减少食品生产环境中生物负载的措施。然而，由于毒性问题，合成抗菌剂（如银、铜、钛和锌）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) 标准的具有天然抗菌整理的纺织品。纺织品样品用Parkia speciosa的乙醇提取物完成. 该提取物对食源性病原体进行了测试，对所有测试微生物均表现出显着的抑制活性，最小抑制浓度范围为 0.32 至 1.25 mg/mL。气相色谱-质谱分析表明，2-[2-(2-乙氧基乙氧基)乙氧基]乙酸乙酯是提取物的主要生物活性成分。成品纺织品在海恩斯坦挑战试验中表现出出色的抗菌功效，生长减少了 90%。即使在用商业洗涤剂洗涤 30 次后，发现成品纺织品的耐洗性也很好。最后，在工业规模的食品加工环境中对开发的纺织品进行的生物负载测试表明，它可以有效地防止微生物污染。
