Flash-freezing is an accelerated process in which fish are frozen immediately after they're harvested. It uses ultra-low temperatures to freeze fish solid in a matter of seconds. In fact, flash-freezing allows fish to be caught, processed, and frozen solid in a matter of hours, not days. By minimizing the time frame between harvest and production, flash-freezing captures the salmon at its peak of perfection. It maintains the look and feel of salmon without the use of artificial preservatives. It also helps fish resist freezer burn for a much longer shelf life. Flash-freezing locks in the nutrition, texture, and flavor that you would expect from premium wild salmon. In addition, the individual vacuum-packed portions are very convenient.
