Flash freezing is a rapid cooling technique that rapidly lowers the temperature of a substance, locking in freshness and preserving its natural properties. Unlike traditional freezing, which can form large ice crystals and damage cell structures, flash freezing keeps the original texture, potency, and quality intact.
Flash Freezing in the Industry
In the hemp and supplement sector, flash freezing is used to preserve freshly harvested flowers and plant material before extraction. By stabilising the product immediately after harvest, this method protects delicate compounds such as cannabinoids, terpenes, and flavonoids from degradation. This is particularly important for maintaining the full aromatic and therapeutic profile of live resin and full-spectrum extracts. The technique is also widely applied in food processing, nutraceuticals, and skincare formulations, where retaining nutrients, flavours, and bioactive compounds is essential. As consumer demand for purity and potency increases, flash freezing has become a standard industry step for premium-grade products.
Example of Flash Freezing Use
A common example is the use of fresh hemp flowers, which undergo flash freezing directly after harvest to produce extracts with a stronger terpene profile. These extracts are then used in tinctures, vape concentrates, or topical balms, ensuring that users experience the plant’s natural character. In food and wellness, flash freezing also preserves ingredients like berries or herbal extracts, keeping them rich in nutrients for use in smoothies, capsules, and functional beverages.
Tips for Understanding Flash Freezing
When choosing products made with flash-frozen extracts, look for transparency from brands that highlight their processing methods, as this signals quality preservation. A common misconception is that all frozen or preserved extracts are the same—flash freezing offers a superior standard compared to slow or traditional freezing. Opting for products that emphasise this method helps ensure a more authentic and effective experience.
