概括
双A (BPA) 从PET瓶中迁移到Doogh随着热量,储存时间和阳光增加. 虽然风险仍然很低,但建议适当储存和更安全的包装以尽量减少暴露.
科学领域:
- 食品科学
- 环境化学
- 毒理学
背景情况:
- 双A (BPA) 是一种在塑料中发现的化学物质,
- BPA可以入食品和饮料中, 引起健康问题.
- 包装在PET瓶中的酸奶饮料 (Doogh) 可能容易受到BPA污染.
研究的目的:
- 调查BPA从PET瓶中迁移到Doogh的情况.
- 评估储存条件 (温度,时间,光线) 对BPA含量的影响.
- 根据危险系数 (HQ) 评估相关的健康风险.
主要方法:
- 在不同的储存条件下对3种Doogh品牌进行分析 (4°C,25°C,45°C;7 - 60天;阳光与阴影).
- 使用固相提取 (SPE) 和高性能液体染色学 (HPLC-UV) 量化BPA.
- 儿童和成人危险系数 (HQ) 的计算
主要成果:
- 更高的温度,更长的储存时间和阳光直接增加了BPA迁移到Doogh (p < 0. 0001).
- 不同品牌的BPA度有所不同,这表明包装或配方的影响.
- 在所有场景中,危险系数 (HQ) 仍然低于值 (<1),但在不利条件下增加.
结论:
- 低于最佳的储存条件 (热量,延长时间,光线) 增加了BPA从PET瓶中迁移到Doogh.
- 虽然目前的健康风险很低,但适当的储存 (冷藏,短时间,阴影) 是至关重要的.
- 建议采用更安全的包装替代品,并对消费者进行储存教育,以尽量减少BPA暴露.

Types of Step-Growth Polymers: Polyesters
2.3K
The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...

Plasticizers
114
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Polymer Classification: Stereospecificity
2.6K
Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...

Polymer Classification: Architecture
2.9K
Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...
