化温度和持续时间显著影响"内比奥洛"葡萄酒的基,影响了素提取和降解. 较高的温度和较长的磨时间会降低最终的葡萄酒安托西亚宁水平,而三替代的安托西亚宁在较低的温度下更好地保存.
科学领域:
- 葡萄酒学 葡萄酒学 葡萄酒学
- 食品化学 食品化学
- 葡萄种植 葡萄种植 葡萄种植
背景情况:
- 化合物对于葡萄酒的颜色,味道和老化潜力至关重要.
- 了解酸提取动态是优化葡萄制造过程的关键,例如"Nebbiolo"等特定葡萄品种.
研究的目的:
- 调查"内比奥洛"葡萄酒生产过程中割温度和持续时间对化合物的影响.
- 分析葡萄酒制作不同阶段 (葡萄,葡萄酒,葡萄,葡萄汁) 的化合物成分.
主要方法:
- 实验室规模的酒实验,控制磨温度 (24°C,29°C) 和持续时间 (12,18,24天).
- 在葡萄皮,葡萄酒,葡萄汁和葡萄汁中分析安东基安和素.
- 葡萄皮软化作为酶活性指标的评估.
主要成果:
- 安索亚宁水平在早期达到峰值,然后下降,温度升高导致发酵期间降解增加.
- 较长的化时间导致最终葡萄酒中氨酸度较低.
- 三替代的安托西亚宁在24°C时表现出更好的稳定性,而在29°C时则表现出更好的稳定性.
- 坦宁含量和结构在很大程度上不受测试条件的影响.
- 提出了一个"预算"来追踪化合物的命运.
结论:
- 化温度和持续时间是影响"内比奥洛"葡萄酒中性特征的关键因素.
- 优化化条件对于管理素提取和降解至关重要,影响葡萄酒的颜色和质量.
- "基预算"概念为了解制过程中的基转换提供了一个框架.

Temperature Dependence on Reaction Rate
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...
