What is the difference between fresh vegetables, frozen vegetables and canned vegetables?

For people, fresh produce usually has some intuitive appeal. Fresh salad, freshly picked vegetables – refreshing and refreshing, watching appetite! On the other hand, preserved agricultural products have long been an unpopular product of the agricultural products family. But what happens to nutrients when fruits and vegetables are canned or frozen?

Bioavailability

What is the difference between fresh vegetables, frozen vegetables and canned vegetables?

Before we look at it, first of all, fresh produce, then frozen products, and finally canned products, let’s talk about bioavailability. Some micronutrients are so tightly integrated in our food that our bodies cannot swing them for digestion. Others are hard to absorb for our bodies. The benefits of loose nutrients and abandoning the body are called bioavailability.

 What is the difference between fresh vegetables, frozen vegetables and canned vegetables?

Cooking can improve certain nutrients The bioavailability reduces the nutrients of other nutrients and therefore increases dietary composition. For example, if we eat them with fat, our bodies are more likely to absorb fat-soluble vitamins (A, D, E and K). In other words, compounds in and around fruits and vegetables can positively or negatively affect the bioavailability of their nutrients.

Fresh produce

What is the difference between fresh vegetables, frozen vegetables and canned vegetables?

We can describe a fruit or vegetable as fresh if it is “mature after harvest” (ie if it matures during transport) or “ripe ripe” (ie if it Picked and mature for sale, such as fresh farms on farms or farmer’s roadside fruit stalls).

You might think that a ripe product is more nutritious because it has more time to absorb nutrients from the soil – in some cases, it is. But plants absorb most of the most important minerals in the early stages of growth, and fruits and vegetables can still synthesize macronutrients and micronutrients during post-harvest ripening.

 What is the difference between fresh vegetables, frozen vegetables and canned vegetables?

Some studies have shown that after harvest Mature agricultural products are nutritionally equivalent to ripe agricultural products – even better in some cases. The nutritional content of any product will depend on many other factors, including soil, season, weather, farming methods, storage conditions and duration.

Agriculturally mature agricultural products are not necessarily more nutritious than post-harvest mature agricultural products. The nutrients of most agricultural products depend on other factors, starting with soil quality.

Frozen products

What is the difference between fresh vegetables, frozen vegetables and canned vegetables?

Normally, frozen products are completely vine-ripened and processed with minimal processing. Most vegetables and some fruits are blanched in hot water for a few minutes before freezing to inactivate enzymes that may cause adverse changes in color, odor, taste and nutritional value.

Although bleaching can leach minerals and break down biomolecules like vitamins, post-harvest products and whitened frozen products have very similar total nutrients. The main effect of blanching seems to be the taste: some fruits and vegetables have a unique selection of flavors, and the blanching process is greatly reduced.

Frozen fruits and vegetables are processed to a minimum.

Canned Products

What is the difference between fresh vegetables, frozen vegetables and canned vegetables?

Canned fruits and vegetables are usually mature vines, such as frozen products, but they tend to undergo more processing. Blanching is common, but the addition of syrup, the addition of salt, and the addition of additives with their own health risks are also common.

Unfortunately, several forms of processing can almost completely break down some essential nutrients, such as nitrates. (You can read about heart health nitrates in ERD 5.) In addition, some cans are lined with bisphenol A (BPA), a chemical associated with an increased risk of cancer, the acidity of the product (eg ketchup). And the heat generated by disinfection can help BPA leak into the things you eat. (You can read more about BPA in this article from ERD 6).

Which is the most nutritious?

What is the difference between fresh vegetables, frozen vegetables and canned vegetables?

Fruits and Vegetables reach the shelves of your store in a variety of ways, each with its own advantages and disadvantages. In addition, the method that best suits one product may not work for another. At the end of the day, different cooking methods have a greater impact on the nutritional content and bioavailability of the product.

The best way is to let you eat vegetables. Whether it’s fresh, frozen or canned, if you eat enough fruits and vegetables every day, you’ll get some nutritional benefits.
