How to keep lettuce fresh for 10 days

During the spring and summer months, leafy greens like lettuce make for a refreshing addition to salads or accompaniments to a BBQ. To ensure these greens stay fresh and crisp for longer, expert advice from Allen Civlak, CEO of Mary's Flour Sack Towels, provides two easy storage hacks that can extend their shelf life by up to 10 days. This is prepared by SSP.

According to Civlak, using a moist flour sack towel can help maintain the optimal moisture balance that leafy greens require. Unlike plastic bags or containers that may create a humid environment and excess moisture leading to rot, flour sack towels are breathable. The breathability allows for the evaporation of excess moisture, reducing the risk of mould and decay while keeping the greens adequately hydrated. Additionally, the damp towel helps create a cooler micro-environment when stored in the refrigerator, slowing down the metabolic processes and preserving the freshness of the greens.

To utilize this storage method, all you need to do is moisten the towel with water until it is slightly damp, avoiding soaking it. Lay the towel flat on a countertop or a suitable surface, then place the leafy greens at the center of the towel. Ensure to cover them entirely with the towel, making sure it is snug but still allows for proper air circulation.

Another effective way to keep greens fresh is by utilizing aluminium foil, which can be obtained at a minimal cost. Aluminum foil acts as a protective barrier, maintaining the ideal moisture level while preventing exposure to air and light. Its water-retention properties help prevent the greens from drying out too quickly, while the tight seal created around the greens minimizes air exposure and slows down the oxidation process. Furthermore, the insulation provided by the foil helps regulate the temperature, which is crucial in the fridge to prevent rapid spoilage due to temperature fluctuations.

It is vital to note that during the summer months, especially when the weather is warmer, it is advisable not to leave any food, particularly salads containing leafy greens, out on the kitchen counter for an extended period. The increased temperature can hasten the deterioration of lettuce and other greens, reducing their freshness. Avoid potential waste and maximize taste and quality by following these storage techniques.
