C andlenut, scientifically known as Aleurites moluccanus, is a flowering tree native to Southeast Asia. It is also known by various names such as kukui nut tree, Indian walnut, and kemiri in Indonesian. The tree produces large, round seeds that are commonly referred to as candlenuts due to their traditional use as a source of oil for candle-making.

The candlenut tree has been cultivated for its nuts, which have a high oil content. The nuts are not typically consumed raw due to their slightly toxic properties, but they are used in various culinary applications after proper processing. The nuts are often roasted or otherwise prepared to remove toxins, making them safe for consumption.

In Southeast Asian cuisine, candlenuts are a common ingredient, particularly in Indonesian, Malaysian, and Singaporean dishes. They are often ground into a paste and used as a base for rich and flavorful sauces, curries, and other dishes. The oil extracted from candlenuts is also used in cooking. Additionally, candlenuts have been used traditionally in various folk medicines and skincare products.

It’s worth noting that while candlenuts have culinary and cultural significance in certain regions, they should be handled and prepared with care due to their toxic nature when raw.

IODINE VALUE: 80-120

The iodine value of an oil is a measure of the amount of iodine that can be absorbed by the oil, indicating its degree of unsaturation or the presence of double bonds in the fatty acid chains. Iodine affects the hardness and conditioning qualities of soap. The lower the Iodine Value, the less conditioning and harder the soap batch will be.  Therefore a soap recipe with iodine values higher than 70 will tend to produce a softer batch of soap. The iodine value is expressed in grams of iodine absorbed by 100 grams of the oil. The iodine value of candlenut oil can vary, and specific values may depend on factors such as the source of the oil and the extraction method. Generally, the iodine value for candlenut oil falls within the range of approximately 80 to 120.

It’s important to note that iodine values are influenced by the fatty acid composition of the oil. Oils with higher iodine values tend to be more unsaturated and may have a greater susceptibility to oxidation. If you need precise information for a specific product or application, it’s recommended to refer to the supplier’s specifications or consult a reliable source for accurate data.

Shelf Life:

The shelf life of candlenut oil can vary depending on several factors, including how the oil is processed, stored, and whether any preservatives are added. In general, the shelf life of most oils, including candlenut oil, is influenced by factors such as exposure to air, light, and heat.

Here are some general guidelines:

  • Unrefined or Cold-Pressed Candlenut Oil: Oils that are less processed and retain more of their natural components, like unrefined or cold-pressed candlenut oil, may have a shorter shelf life. They are typically best used within 6 to 12 months.
  • Refined Candlenut Oil: Refined oils undergo a more extensive processing method, which may include filtration and removal of impurities. Refined candlenut oil tends to have a longer shelf life compared to unrefined versions and can last up to 12 to 18 months or more.

To maximize the shelf life of candlenut oil:

  • Store it in a cool, dark place, away from direct sunlight.
  • Keep the container tightly sealed to prevent exposure to air.
  • Avoid exposing the oil to extreme temperatures or fluctuations in temperature.

It’s important to note that over time, oils can become rancid due to oxidation. Signs of rancidity include a change in color, an off smell, or a bitter taste. If you notice any of these signs, it’s advisable to discard the oil.

Always check the manufacturer’s recommendations and any expiration date provided on the product packaging. If you’re unsure about the quality or safety of the candlenut oil, it’s best to replace it with a fresh supply.

Best Used By: Use within one year from date of purchase. Exposure to extreme heat will lessen the shelf life of almond oil
Storage: Room temperature. Airtight container.
