Orange peel can be used in its original form or in the form of essential oil extracted from it.

Orange Peels Health Benefits


What Is Orange Peel?

Orange peel may refer to the fresh zest of an orange or the dehydrated one. The fresh peel of an orange is taken during the peeling process. The outer layer of orange skin is taken and then cleaned from its pith, the white membrane that surrounds the fruit.

If the pith is included, the combination of the peel and the pith is called orange rind. It is also possible to use the peel directly without peeling the fruit. If you want to make an orange juice with its peel included, you only need to make thin slices of the fruit without removing the skin. This way, you actually use the rind instead of the peel. You can then extract the juice by putting the orange slices with its peel in a juicer.

Orange peel can be dehydrated for easier storing and serving. Although the dehydrated peel of an orange has similar nutritional value to that of the fresh one, dehydrated peel is considered three times as strong as fresh peel. When reading a recipe that includes orange peel, you should confirm whether the recipe requires you to use fresh peel or dried one. If the recipe requires you to use 1 tablespoon of fresh peel, you can use 1 teaspoon of dried peel.

What Is Orange Peel Extract?

Orange peel is also available in the form of essential oil that is extracted from it. There are various extraction methods that can be used to extract the oil from the peel, including distillation, cold press, absorption, maceration, and expression. It is also possible for you to extract the oil at home. You will read about it in the recipes section of this article.

There are obvious advantages of using orange peel extract instead of the tough peel. If you use orange peel extract, you are using oil that is guaranteed to be free from contaminants and to be least likely to cause digestion problem. Orange peel extract is now available in many shops as over-the-counter product.

If you want to eat orange peel, especially in its hard form, you have to make sure that the peel comes from a reputable source.

  1. Stimulant risk

Orange peel contains ephedra-like stimulant that is called synephrine. If you consume orange peel or its oil extract too much, you might be at risk of experiencing the adverse effects triggered by this stimulant, including restlessness, insomnia, vision problem, weakness, and nervousness. Synephrine is also known to cause headache and to exacerbate hyperthyroidism and hypertension.
