酒厂商在探索新的酒风味时会使用替代的添加剂,比如菜和杏仁. 粉碎工艺的效率各不相同,国会粉末产生最好的结果,而前凝化只是有时有益的.
科学领域:
- 造科学 造科学
- 谷物科学 谷物科学
- 食品技术 食品技术 食品技术
背景情况:
- 消费者对新酒的需求促使酒商探索替代原料.
- 纯粹的替代添加剂为新的酒风味和口味提供了自然的途径.
- 将这些添加剂纳入造需要仔细考虑制过程.
研究的目的:
- 为了研究10个未的替代附加剂的粉碎行为和特征.
- 为了比较三种不同的实验室粉碎工艺 (国会,先化国会和埃文斯) 与这些附加剂的有效性.
- 评估辅助前凝化对粉碎过程的影响.
主要方法:
- 40%的混合10个未麦的替代添加剂 (独角兽,埃默,,霍拉桑,菜,杏仁,白麦,,特夫,特里托) 或参考谷物与60%的大麦麦芽.
- 三种实验室粉碎程序:国会粉碎,国会粉碎与前凝化,和埃文斯粉碎.
- 详细分析粉碎行为和由此产生的特征.
主要成果:
- 在所有粉碎方法中,在所有10个未经粉碎的替代附加剂中都观察到不完整的提取.
- 国会粉碎产生了最高的提取产量和最快的过率.
- 埃文斯粉碎导致了最低的提取产量和最慢的过; 前凝化只对具有高粉凝化温度和失活的内源酶的附加剂有益.
结论:
- 选择的粉碎工艺显著影响提取物产量和过,当使用非马尔特替代附加剂.
- 在最大限度地提高提取和过效率方面,国会粉碎似乎是最有效的.
- 凝化前需要仔细评估,因为它可以通过使关键酶失活,对粉碎过程产生负面影响.

Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...

Ethers from Alkenes: Alcohol Addition and Alkoxymercuration-Demercuration
Ethers can also be prepared from alkenes through acid-catalyzed addition of alcohols and alkoxymercuration–demercuration.
Preparation of Ethers by Acid-Catalyzed Addition of Alcohol to Alkenes
The acid-catalyzed addition of alcohol to an alkene involves treating the alkene with an excess of alcohol in the presence of an acid catalyst to form an ether under suitable conditions. The hydrogen will add to the less substituted carbon so that the nucleophile can attack the more...
