Secrets to Preparing Perilla and Lemon Drink to Preserve Nutrients

Perilla leaves (Perilla frutescens) have long been recognized for their high content of antioxidants, such as polyphenols and flavonoids, combined with essential oils that create a distinctive aroma. Meanwhile, lemons are a rich source of vitamin C and beneficial plant compounds. However, improper thermal processing can lead to the degradation of these active ingredients.

To ensure the beverage reaches its highest quality, the primary rule is to avoid boiling the perilla leaves for too long, as prolonged high temperatures dissipate their clean aroma and cause the brew to become astringent. Notably, the vitamin C in lemons is highly heat-sensitive; therefore, lemon juice should only be added once the perilla infusion has cooled down.

Optimal preparation technique: Bring water to a boil, then add the prepared perilla leaves and simmer over low heat for approximately 3-5 minutes. This duration is sufficient to extract the aromatic essences without producing an overpowering odor. Once the water turns a light purple, turn off the heat and let it cool naturally.

After the infusion has cooled completely, proceed to add the lemon juice. Upon contact with the acidic environment from the lemon, the anthocyanin pigments in the perilla leaves will undergo a chemical reaction, shifting to an appealing pink or purple-red hue. This reaction is entirely natural and safe for consumption.

While perilla and lemon drinks provide a refreshing sensation and minor health support, users should be mindful not to rely solely on this drink as a detoxification or deep cleansing method, as there is currently no scientific evidence confirming its ability to replace medical treatments.
