As is well known, nutrients in ingredients can easily be lost after cutting, and they can even spoil. However, in daily life, many ingredients cannot be used immediately after being cut. So, how should cut ingredients be stored? Below, I'll share a few tips with you.
Coat the lemon cut with honey
People usually only eat one or two slices of lemon at a time. Many people simply wrap the remaining lemon in plastic wrap and put it in the fridge. In fact, you can first apply a layer of honey to the cut surface before sealing it with plastic wrap. This is like giving the lemon a "double layer of protection." It not only effectively prevents bacteria from getting in but also stops moisture and nutrients from escaping, extending its shelf life to 3-5 days. Additionally, even if the peel of a lemon has dried out, the inside is still juicy, so don't discard it; you can use it to make lemon tea.
For pumpkin, first remove the seeds and pulp
A whole pumpkin has a thick, tough rind and can be stored for up to two months in a cool, dry place with the stem facing up. However, a cut pumpkin is not easy to store and tends to spoil from the "inside out." This is because the pulp has a high sugar content. When stored for a long time after being cut, the pulp undergoes aerobic fermentation, causing the pumpkin to become moldy and rotten and to develop a foul odor. Therefore, it's best to first remove the seeds and pulp from a cut pumpkin, wrap it in plastic wrap, and then refrigerate it. This allows for short-term storage, but it's best to eat it within 1-2 days to prevent spoilage.
For winter melon, cover the cut with a piece of paper
Winter melons are quite large and are often difficult to finish in one go. The surface of a cut winter melon has a layer of liquid that can easily breed bacteria and cause spoilage. It's best to cover the cut with a clean piece of white paper to absorb the liquid, then wrap it in plastic wrap and refrigerate it. This can keep it fresh for about 3 days. It's worth noting that when you eat it again, it's best to cut off and discard a thin layer from the cut surface.
Wash the knife before cutting the watermelon
Although the inside of a watermelon is sterile before being cut, once it's exposed to the air and the surface of the fruit knife, bacteria can be introduced. If left for a long time, bacteria can multiply rapidly, causing the watermelon to spoil. Therefore, you should pay attention to the cleanliness of the fruit knife's surface when cutting a watermelon; it's best to wash it first. Cut watermelon should not be left out for long. At room temperature, it can generally only be kept for about 4 hours. Any leftover watermelon should be wrapped in plastic wrap and promptly placed in the refrigerator.
Wrap green onions, ginger, and garlic in aluminum foil
The moisture content in green onions, ginger, and garlic directly affects their quality. If placed on a balcony, they will dry out and wither, but if stored in the refrigerator, they will sprout and grow mold. Therefore, maintaining the right amount of moisture is key. Here's a recommended method: cut aluminum foil to a suitable size, then wrap each item separately. Try to make the foil fit the food as tightly as possible, and then store them in a cool, ventilated place indoors. This way, they will not spoil even after 2-3 weeks. A special note: do not wash green onions, ginger, or garlic before storing them.
