How to Identify High-Quality Purple Perilla Oil

April 10, 2024

When it comes to selecting Purple Perilla Oil, quality is paramount to ensure the health benefits and optimal usage. Here are some key factors to consider:

Certification and Regulation

Look for oils that have been certified organic and have met the standards set by regulatory bodies. For instance, in the European Union, Perilla seed oil possesses "Novel Food" status and must be authorized under the Novel Food Regulation 8.

Extraction Method

The method of extraction can significantly impact the quality and nutritional content of the oil. Cold-pressed oils are often preferred as they retain more of the natural nutrients and flavors. Solvent extraction, while effective, can result in a lower content of active ingredients 1.

Chemical Composition

High-quality Purple Perilla Oil should have a balanced and desirable chemical composition. It should have a low free fatty acid content, peroxide value, and UV absorption, indicating good conservation and freshness. The oil should also have a high content of polyphenols, such as rosmarinic acid, which contribute to its health benefits 8.

Taste and Aroma

A high-quality oil will have a distinct and pleasant aroma, characteristic of the Perilla plant. The taste should be nutty and slightly aromatic without any rancid or off-flavors.

Packaging

The packaging of the oil is also an important factor to consider. It should be stored in dark bottles to protect it from light, which can degrade the oil over time.
