干燥的古吉中的农药残留物对食品安全构成威胁. 洗和加工方法可以减少残留物,但风险仍然存在,需要更安全的种植和加工方法.
科学领域:
- 食品科学 食品科学 食品科学
- 农业化学 农业化学
- 环境毒理学环境毒理学
背景情况:
- 果在全球范围内被消费,但在种植和加工过程中容易受到农药污染.
- 农药残留物对古吉果的质量和安全造成重大关注.
研究的目的:
- 为了识别和量化来自中国的干果中的农药残留物.

- 为了评估与商业消费果相关的饮食风险.
主要方法:
- 从中国市场取样了75批干燥的古吉果.
- 分析了28种农药,使用62种分析物的方法.
- 确定农药的半衰期,加工因子 (PF) 和去除率.
- 慢性风险的计算危险指数 (HI) 和急性风险的HQa.
主要成果:
- 九种高残留量农药的半衰期为1.042.21天.
- 果汁加工系数在0.251.02之间,受logKow.的影响.
- 洗清除了17.00%74.05%的残留物;阳光干燥丰富的残留物 (PFs 0.615.91).
- 商用古吉果呈现累积慢性风险 (HI 1.61%4.97%) 和高急性风险 (HQas 543.32%585.92%),主要来自杀虫剂.
结论:
- 果加工会影响农药残留量,而阳光干燥则会显示丰富性.
- 目前商业化的古吉果对消费者构成严重的急性和慢性饮食风险.
- 提供了优化农药使用和改进加工以提高食品安全的建议.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
