Walnut Oil Nutrition, Benefits, and How to Use it

Whether you’re drizzling it over salads, or using it in marinades, walnut oil is incredibly versatile. This article will explore 16 fantastic benefits of walnut oil. Plus, we will also provide you with detailed insights into how to use it effectively.

What is Walnut Oil?

Walnut oil is derived from the seeds of the walnut tree, primarily the English walnut (Juglans regia). The oil is extracted through a process of pressing shelled walnuts, which can be done either cold or hot.

Cold-pressed walnut oil retains more nutrients and has a fresher flavor. Hot-pressed oil may have a stronger taste but can lose some beneficial compounds during processing.

Note that walnut oil has a low smoke point (around 320°F or 160°C), so it’s best used for low-heat cooking or added to dishes after cooking.

How to Make Walnut Oil at Home?

Making walnut oil at home can be a rewarding process, allowing you to enjoy fresh, cold-pressed oil packed with nutrients. Here’s a simple method to create walnut oil using a small oil press machine.

Ingredients and Equipment

• 300 grams of shelled walnuts (about 10.5 ounces)
• Small electric oil press machine (cold press type)
• Mason jar or glass container for storage

Instructions

1. Prepare the Walnuts: If your walnuts are not already shelled, remove the shells and break them into smaller pieces. This will make it easier for the oil press to extract the oil.

2. Set Up the Oil Press: Follow the manufacturer’s instructions to set up your small electric oil press machine. Ensure it is clean and ready for use.

3. Press the Walnuts:

• Place the walnut pieces into the machine’s hopper.
• Turn on the machine and let it run for about 5 minutes. The pressing process should extract the oil from the walnuts.
• Collect the oil as it flows out of the machine into a container.

4. Filter the Oil: After pressing, you may notice that the oil is cloudy due to sediment. To clarify it:

• Pour the freshly pressed oil into a mason jar.
• Allow it to sit for a few days so that any sediment settles to the bottom.
• Once settled, carefully pour off the clear oil from the top into another container, leaving the sediment behind.

5. Storage: Store your walnut oil in a sealed mason jar or glass bottle in the refrigerator. It can last for several months when stored properly.

Potential Side Effects and Risks

While walnut oil offers numerous health benefits, there are some potential side effects and risks associated with its consumption:

• Allergic Reactions: Some individuals may be allergic to walnuts or other tree nuts. Consuming walnut oil could trigger allergic reactions ranging from mild symptoms like hives to severe anaphylaxis.
• High-Calorie Content: As with any fat source, moderation is key when using walnut oil due to its high-calorie content; excessive consumption could lead to weight gain if not balanced within an overall healthy diet.
• Oxidation: Walnut oil has a relatively low smoke point. So using it at high temperatures can lead to oxidation which diminishes its nutritional value and produces harmful compounds.
• Interactions with Medications: If you’re on anticoagulant medications (blood thinners), consult a healthcare provider before adding significant amounts of walnut oil to your diet.

FAQs

1. Is walnut oil healthy?

2. How should I store walnut oil?

Walnut oil should be stored in a cool, dark place, preferably in a tightly sealed container to prevent oxidation. It’s best kept in the refrigerator to extend its shelf life. Always check for rancidity before use; if it smells off or tastes bitter, it’s time to discard it.

3. How much walnut oil should I consume daily?
