Can You Tell if Hemp Oil is Rancid?

Like many other packaged natural products, hemp oil has a shelf life. How long the oil will last once you break the seal depends on a number of factors including room temperature and exposure to light. At this point, the primary question is, “how do you know if hemp oil is rancid?” 

How long can hemp oil last? 

Before we can look at the key indicators that show CBD oil might have gone bad, let us take a step back and ask, “How long was it manufactured to last?” 

Notably, there is no specific answer to the question because different formulations cause varying shelf lives. However, most hemp oils out there have a range of one to two years. If your oil reaches the end of its life, the compounds break down, rendering it less efficient. 

But many people do not even have to worry about the shelf life because they exhaust their oils long before hitting 25% of the shelf life. For example, if you have a bottle of 300mg of CBD and take a regular dose of 10mg, you will use the entire bottle in about four weeks. This is way ahead of the expected expiry date.  However, it is still crucial to know how to identify rancid hemp oil so that you do not buy expired products. 

Signs that hemp oil has gone rancid 

One thing you need to appreciate when it comes to hemp oil is that it is natural. This means that with time, especially if kept poorly, it will get spoiled. So here are the signs to look out for: 

  •     Hemp oil that has changed color 

When hemp oil expires, its components start degrading, resulting in a change of color and texture. The right color of hemp oil varies from white (nano-liposomal CBD) to clear to dark brown. Therefore, if you note the formation of a foggy precipitate in the bottle, chances are that it has expired. Simply throw that bottle away. 

  •     Change in smell 

When natural products start decomposing, they can generate a foul smell. This is especially likely to happen if your CBD oil is stored poorly. If you notice a change in smell from the normal smell of the CBD, it is an indication that it is bad and should be disposed of. 

  •     The hemp oil has expired on the seller’s shelf 

As we have pointed out, the recommended shelf life of most hemp oils is one to two years. Therefore, if you are purchasing the oil, the first place to check is the expiry date. If the shelf life has passed or is approaching, do not buy it! Instead, it’s best if you focus on selecting oils that are fresh for optimal use.  

  •     Incredibly low price 

Not to imply that all cheap CBD oils are rancid, but when offered a price that is too good to be true, it is best to double-check the product. A dealer may sell poor quality or expired hemp oil at suspiciously low rates. Therefore, take a closer look and ask the following questions: When was the hemp oil made? Who is the manufacturer? Does the manufacturer subject the hemp oil to third party testing?

How to preserve your CBD properly

Now that you know the signs of rancid hemp oil, here are the best ways to store it without losing its potency. 

  •     Make sure to follow manufacturer’s instructions

Notably, all CBD-based products are not created equal. For example, there are manufacturers who use organic solvents for oil extraction, while others use more advanced technology, such as supercritical CO2 extraction. Because of these dynamics, each manufacturer has a set of instructions and tips that can help to keep the product stable. 

  •     Do not leave hemp oil sitting for too long

One of the best ways of staying away from bad CBD oil is by purchasing the right quantities. No need to stockpile CBD oil. Instead, order in moderation. 

  •     Prevent exposure to air 

If air gets into your CBD oil, it can cause degradation and reduction of shelf life, so ensure the oil is kept in airtight bottles. After use, make sure to seal the bottle completely to limit air getting in. 

  •     Store in a cool place away from heat 

The main secret to keeping your hemp oil in top condition is ensuring it stays in a temperature controlled environment. It’s best to keep the oil from changes in surrounding conditions, especially heat, light, and moisture. 

Notably, because the oil comes in the form of a carrier liquid, consider storing it the same way you would for coconut or olive oil – simply cool and dry. (Never freeze!)

When hemp oil goes rancid, it’s best to throw it away. These guidelines  have demonstrated how to identify bad oil and how to keep your supplies stored properly. Simply buy high quality oil, avoid contamination, and keep in a dry, temperature-controlled place. 

Miron glass is an excellent choice for the storage of hemp oil.

Most products decay or deteriorate in natural light, especially sunlight, which accelerates the process of molecular decay in natural compounds. But dark-colored Miron glass blocks the complete spectrum of visible light with the exception of violet, ultraviolet and infrared light. Miron glass is exceptionally good for storing and preserving the contents of any product that has a high sensitivity to light with minimal or no degradation for long periods of time.
