由于不和脂肪酸,日本胡无糖很容易降解. 抗氧化剂,如阿尔法-托科菲罗尔和某些酸有效地稳定桑斯霍尔,防止降解.
科学领域:
- 食品化学 食品化学
- 自然产品化学 自然产品化学
- 植物化学 植物化学
背景情况:
- 桑舒尔,在日本胡 (Zanthoxylum piperitum) 中发现的N-胺,由于其不和脂肪酸成分,易受氧化降解.
- 这种降解在加工和产品开发中带来了挑战,影响了桑沙的特色味道和风味.
研究的目的:
- 评估抗氧化剂的有效性,特别是来自Zanthoxylum属的抗氧化剂,以防止桑索尔降解.
- 确定可以稳定氧-α-sanshool (HαS) 和减轻氧化恶化的特定化合物.
主要方法:
- 进行了加快的稳定性测试,以桑肖果香的乙醇提取物进行了测试.
- 提取物在70°C进行了7天的化,并添加了各种抗氧化剂,以量化残留的氧-α-sanshool (HαS).
- 评估了alpha-tocopherol (α-Toc) 和几种化合物 (酸衍生物,氨酸,hesperetin,naringenin) 的稳定活性.
主要成果:
- 阿尔法-托科菲罗尔 (α-Toc) 即使在低度下也表现出显著的HαS稳定活性.
- 酸显示HαS稳定活性增加,具有较多的基组;酸衍生物和氨酸特别有效.
- 虽然有效,但相对于α-Toc,烯化合物需要更高的度来实现可比稳定.
结论:
- 抗氧化剂,包括α-Toc和特定的化合物,可以有效地防止Zanthoxylum piperitum提取物中的sanshool降解.
- 这些发现表明,天然存在的抗氧化剂在植物内保存无洞中发挥着作用.
- 鉴定到的sanshool稳定剂有可能用于食品,饮料,化品和制药行业,以利用sansho独特的感官特性.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
