Olive oil has become very popular over the last decade. People are using it in their cooking and even drinking it as a health drink. What exactly is olive oil? How does it differ from other oils?

Olive oil is a type of vegetable oil extracted from olives. It is rich in monounsaturated fatty acids (MUFAs) and polyphenols. These compounds are known to improve heart health, lower cholesterol levels, reduce inflammation, prevent cancer and boost immunity.

There are two main types of olive oil: extra virgin and refined. Extra virgin olive oil is unrefined and contains higher amounts of antioxidants and vitamins compared to regular olive oil. This makes it healthier.

Have you ever wondered why potatoes turn brown after they’ve cooked? This happens because the starch inside them turns into sugar called glucose. If you don’t want your potatoes to become dark, try adding some olive oil or butter before cooking them.

Potatoes are a staple food around the world. They come in various varieties such as white, red, yellow, sweet, purple, etc. These vegetables contain high levels of carbohydrates and potassium, along with other nutrients.

Olive oil has antioxidant properties that can prevent oxidation from occurring. As a result, the color of your potatoes will remain bright orange instead of turning brown.

There are two main reasons why potatoes get discolored when cooked in olive oil: oxidation and Maillard reaction. Oxidation occurs when fat molecules react with oxygen in air. This causes fats to become rancid, turning into odors and flavors that affect the taste of food.

Maillard reaction happens when amino acids (the building blocks of proteins) react with sugars, forming new compounds called melanoidins. These new compounds give food its color and flavor.

Why Do Potatoes Turn Brown?

The reason why potatoes turn brown is because of oxidation. When you cook potatoes in olive oil, the oil reacts with the starches in the potato causing them to turn brown. This process is called oxidation.

Oxidation is caused by free radicals which are unstable molecules that have an unpaired electron. Free radicals are formed during normal metabolism and cause damage to cells.

How Does Cooking In Olive Oil Affect Potatoes?

When you cook potatoes in olive oils, the oil reacts with moisture and heat to form free radicals. These free radicals then attack the starch molecules in the potato, causing them to break down. This results in the formation of brown pigments.

When you cook potatoes in olive or any other oil, they will still be healthy. You just need to know how to prepare them properly so that they won’t turn brown.

What Are Some Ways To Prepare Potatoes Without Making Them Dark?

You should always wash your potatoes well before cooking them. Washing removes dirt and helps make the skin crispy.

You should cut off the ends of the potatoes before boiling them. Cutting off the ends prevents the starch from escaping out of the potato. Starch escapes through the cuts and forms a crust on the surface of the potato . This makes it look darker than it really is.

If you’re going to boil your potatoes, use enough water to cover them completely. Boiling potatoes in too little water means that the starch will not escape out of the potato. This leads to a dark colored potato.

If you want to bake your potatoes, you should coat them first with olive oil. Baking potatoes without coating them in oil will lead to a darker-colored potato.

Do I Need To Cook Potatoes With Olive Oil?

How Long Can Potatoes Be Frozen?

Freezing also causes the starches in the potatoes to harden. Hardening reduces the amount of nutrients available to the body.

Cold Water

Olive oil is extracted from olives using mechanical pressing. It is obtained after crushing the olives and separating the olive juice from the pulp. This process is done manually or mechanically. In manual method, the olives are crushed between two heavy plates called press stones. These stones crush the olives and separate the olive juice from the olive pulp. The olive juice is collected in a trough below the press stones. The olive pulp is discarded. In mechanical method, the olives pass through a series of rollers that squeeze the olive juice out of the olives. The olive juice flows into a tank where it is separated from the olive pulp.

Lower The PH

PH stands for potential hydrogen. It is a measure of acidity. A pH level of 7 indicates neutral. Anything lower than 7 is acidic and anything higher than 7 is alkaline. Most fruits and vegetables have a pH level of 4 to 6.5. However, if you eat something that has been sitting around for a long time, it could have a very low pH level. For instance, a banana that has been sitting around in your refrigerator for a couple days has a pH level of 2.0. That’s why bananas are good for baking because they help leaven breads.

Add Salt

Salt is used to preserve food and flavor it. It helps to retain moisture in meat and fish. It also adds flavor to many dishes. Salt is added to food during cooking or right after it comes out of the oven. Salt is usually sprinkled on top of cooked food. Sometimes salt is mixed into sauces or dips.
