In this brief guide, we will answer the query, “How to store carrots in the fridge?” and will discuss different ways to store carrots in the fridge.
How to store carrots in the fridge?
Carrots may be stored in a variety of ways in the refrigerator. Whole, peeled or chopped carrots may be stored in dry, sealed containers or a sealed container of water. Carrots may be stored in the refrigerator for up to three months.
How to Store Carrots in the Fridge: A Complete Guide
Carrots (Daucus carota L.) are one of the most popularly consumed vegetables. Carrots for the fresh market may be stored for as long as 6 months at refrigerated temperatures just above 0°C and at humidity levels approaching saturation. The quality and storage life will, however, eventually decrease by loss of moisture, physiological breakdown, decay, and development of undesirable taste and flavor compounds. However, carrots maintain most of their vitamins and flavor compounds during refrigerated and frozen storage (1).
Carrots may be stored in a variety of ways, depending on whether or not they are fresh, peeled, sliced, or cooked. You don’t have to be a rocket scientist to keep your carrots fresh and flavorful in the fridge, but there are a few things you should keep in mind.
A wide array of carrot alternatives may be found since there are so many ways to prepare and use carrots. Consider all of your possibilities before deciding on what kind of carrots you’ll be using.
For those of you who have never eaten a carrot before, here’s a little refresher course. As a root vegetable, carrots fall under this category. Although orange is the most popular color, it is possible to find them in black, gray, or a variety of purple, red, or yellow hues as well. The tastes of various hues might vary somewhat.
There are several health advantages of eating carrots, as well as an abundance of minerals. Beta carotene, fiber, potassium, Vitamin K1, and many antioxidants are all found in these vegetables. They’re well-known for helping people lose weight, keep their vision health, and lower their cholesterol.
Carrots are the major vegetable source of provitamin A carotenoids (especially a-carotene) in the human diet, which have been reported to be protective against certain types of cancers and to have other health benefits (2).
Steps to Store Carrots in fridge
Carrots may be stored in the refrigerator by these guidelines. Carrots may come under a wide range of conditions in the following areas.
For the most part, the information in this section is based on raw, uncooked carrots. However, if none of the other parts meet your requirements, we want to direct you back to this area as your fundamental go-to.
Carrots may be stored for a long time if they are properly chilled. Carrots may be stored in the refrigerator for up to three months. However, this is an unusually long period for any other form of vegetable or even food.
Remove any green stems or leaves from the carrots before keeping them in the refrigerator (if there are any). When you eat your carrots, you may or may not notice that they still have some of their leaves on them.
When it comes to keeping carrots in the refrigerator, follow these instructions for the best results:
· We suggest that you wait until you’re ready to utilize the carrot before washing it. It may dry out in the fridge after you’ve washed it. They might also go bad if there is too much moisture in the air.
· Remove any leaves or vegetation off the top of your carrots before cooking.
· Seal a plastic bag with your carrots inside of it. Ziplocs and other storage bags are recommended, although you may be able to use the bag they came in from the store. Before closing the bag, remove any remaining air.
· Refrigerate the bag of carrots in the coldest area of the unit you have. A refrigerator’s temperature may vary from one to the next. You might want to look in the refrigerator’s vegetable drawer or near the freezer or refrigerator’s fan.
· Refrigerate for up to three months before using. However, it’s a good idea to consume them within a few weeks to be safe.
· To ensure that carrots last as long as possible in the refrigerator, make sure they are well wrapped. Carrots may dry out if exposed to air for an extended period.
Pros and Cons of Refrigerating Carrots
For your convenience, we’ve compiled a concise rundown of the benefits and drawbacks of preserving carrots.
The Benefits of Refrigerated Carrot Storage:
· It is possible to store carrots for up to three months.
· It’s a rather straightforward procedure.
· There are no complicated or onerous requirements to meet.
· All you need is an airtight storage bag or container.
· Preserving carrots is easier than most other foods in the refrigerator.
· Unwashed and uncut, they may be stored.
Chemical reactions occur in the vitamins and volatiles of carrots during storage. A study evaluated the chemical compounds of carrots during 4 months of refrigerated storage. I revealed that the concentration of total volatiles increased significantly. During this period the concentration of monoterpenes doubled, while that of sesquiterpenes increased almost 5-fold, indicating that secondary plant metabolism was very active during postharvest storage of carrots. On the other hand, studies reveal that the amount of sugar in carrots decreases rapidly during storage. Harsh and oily flavor of carrots is associated with elevated levels of terpenoids, and a reduced sugar content, whereas sweetness and overall preference seem to be related to a high concentration of sugars and a reduced level of terpenoids (1). In addition, the amount of phenolics increased. Chlorogenic acid and related compounds increased during storage. Studies showed that wounding in combination with other postharvest abiotic stresses, such as hormone, controlled atmospheres, heat shock, hyperoxia stress, UV radiation, herbicide and water stress, can synergistically increase the accumulation of phenolic antioxidants in carrot (3).
Refrigerating Carrots: drawbacks
· Possibly, the carrots will get a little dry.
· Because of this, it’s impossible to predict how long they’ll survive after three months.
· Store them unwashed, please.
· Greens and leaves may need some preparatory work.
According to studies, carrots lose their moisture during storage. This loss of moisture causes a shriveling, which begins with the skin, and gradually gains interior tissues and this causes loss of weight. The amount in sugar decreases during storage. After 60 days, the sugar content was about half of the initial value. The ratio of non-reducing to reducing sugars exhibited a sharp increase after 14-18 wk of storage. In long-term storage, the carrots began to form shoots and rootlets and carotene increased slightly and the amount in amino acids decreased (2).
Keeping your carrots in the fridge is a better option than keeping them in the pantry since the benefits significantly outweigh the drawbacks. Carrots may be stored in a cold, dark place outside of the refrigerator. Think of a basement or a comparable place. However, we don’t need to discuss freezing and canning choices in this article. However, we suggest that you store your fresh carrots in the refrigerator for the best and longest benefits possible.
