科学家制作了一部改变颜色、生态友好的电影,以监测海产食品的新鲜性,协助食品安全。 Scientists develop a color-changing, eco-friendly film to monitor seafood freshness, aiding food safety.

NIT Rourkela的研究人员制作了一部可生物降解的智能薄膜,使用诸如Kodo小米淀粉和甜菜根皮提取等天然材料来监测海产食品的新鲜度。 Researchers at NIT Rourkela have created a biodegradable, intelligent film using natural materials like Kodo millet starch and beetroot peel extract to monitor seafood freshness. 影片根据pH值在48小时内将颜色从红色改变为黄色,显示新鲜或变质。 The film changes color from red to yellow within 48 hours based on pH levels, indicating freshness or spoilage. 这项创新在《食品包装和储存寿命》中发表,目的是改善食品安全,减少海产食品行业的废物。 This innovation, published in Food Packaging and Shelf Life, aims to improve food safety and reduce waste in the seafood industry.
