Did you store perilla oil in a kitchen cabinet or room temp pantry like olive or sesame oil? Perilla oil contains over 60% omega-3 fatty acids, causing it to oxidize rapidly, rancidify, and generate harmful carcinogens at room temp. Today, FreshSnap shares cold storage hacks.

This storage guide is verified based on official guidelines from the RDA & MFDS.
1. Why store like this? Scientific facts
Understanding the unique characteristics of each ingredient and following the proper storage method is extremely important for maintaining freshness and hygiene.
2. Scientifically Proven Storage Guide
Always store in the refrigerator at 0–4°C — Refrigerated Storage (30Days)
Unlike sesame oil, perilla oil lacks sesamol, a natural preservative, and contains over 60% omega-3 fatty acids, making it highly susceptible to rancidity at room temperature. Always store it in the refrigerator at 0–4°C.
Use dark glass bottles and limit air exposure — Block oxygen 🫙
Light and oxygen accelerate the oxidation of omega-3. Perilla oil must be kept in brown or green glass bottles, and the cap must be closed tightly after each use to minimize contact with air.
Mix perilla oil and sesame oil at an 8:2 ratio — Natural preservative 🫒
Try mixing perilla oil with sesame oil at a 20% ratio. Natural antioxidants in sesame oil, such as lignan, powerfully block the oxidation of perilla oil, doubling its shelf life.
3. Crucial Rules and Cautions
Exposure to oxygen and light causes perilla oil to spoil fast. Keep it sealed in dark bottles inside the fridge.
Sesame oil is rich in sesamol and sesamolin, natural antioxidants that prevent perilla oil from rancidifying.
📍 Frequently Asked Questions (FAQ)
Does mixing perilla oil with sesame oil increase its shelf life? ▼
Yes, sesame oil contains sesamol, a powerful antioxidant. Mixing perilla oil and sesame oil in an 8:2 ratio and storing it can double the preservation period of perilla oil.
Should sesame oil be refrigerated too? ▼
No, sesame oil is rich in antioxidants, so storing it at room temperature in a dark place is best to protect its flavor. Refrigeration may cause sedimentation and weaken the aroma.
