Understanding Potato Chemistry
Before we dive into the nitty-gritty of prepping raw potatoes, it’s essential to understand the chemistry behind these starchy vegetables. Potatoes contain a type of starch called amylopectin, which is responsible for their characteristic texture and flavor. When potatoes are cut or bruised, the starches are released, and an enzyme called polyphenol oxidase (PPO) is activated, causing the potatoes to turn brown or black. This reaction, known as enzymatic browning, can be slowed down or prevented by using various techniques, such as soaking the potatoes in cold water or adding acidic ingredients like lemon juice.
The Effects of Oxygen on Potatoes
Oxygen plays a significant role in the degradation of potatoes. When potatoes are exposed to oxygen, the starches are broken down, and the potatoes become softer and more prone to spoilage. This process can be accelerated by factors such as heat, light, and physical damage. To minimize the effects of oxygen on potatoes, it’s crucial to store them in a cool, dark place, and to handle them gently to avoid bruising.
