Canned food is very fresh
The main reason most people abandon canned food is because they think canned food is not fresh.
This prejudice is based on consumers’ stereotypes about canned food, which makes them equate long shelf life with staleness. However, canned food is such a long-lasting fresh food with a long shelf life.
1. Fresh raw materials
In order to ensure the freshness of canned food, canned food manufacturers will carefully select fresh food in the season. Some brands even establish their own planting and fishing bases, and set up factories nearby to organize production.
2. Canned food has long shelf life
The reason for the long shelf life of canned food is that canned food undergoes vacuum sealing and high-temperature sterilization in the production process. The vacuum environment prevents the high-temperature sterilized food from contacting the bacteria in the air, preventing the food from being contaminated by bacteria at the source.
3.There is no need preservativesat all
In 1810, when canned food was born, modern food preservatives such as sorbic acid and benzoic acid had not been invented at all. In order to extend the shelf life of food, people used canning technology to make food into cans.
When it comes to canned food, most people’s first reaction is to “refuse.”. People always think that preservatives can prolong the shelf life of food, and canned food usually has a long shelf life, so many people mistakenly think that canned food must have added a lot of preservatives. Is canned food added with a lot of preservatives, as the public says?
preservative? Not at all! In 1810, when cans were born, because the production technology was not up to standard, it was impossible to create a vacuum environment. In order to extend the shelf life of food, manufacturers at that time might add preservatives to it. Now in 2020, the development level of science and technology has been very high. Human beings can skillfully create a vacuum environment to ensure the hygiene of food, so that the remaining microorganisms can not grow without oxygen, so that the food in cans can be preserved for a long time.
Therefore, with the current technology, there is no need to add preservatives to it. For canned food, most people still have many misunderstandings. Here are some solutions:
1. Canned food is not fresh?
The main reason why many people don’t like canned food is that they think canned food is not fresh. Most people subconsciously equate “long shelf life” with “not fresh”, which is actually wrong. Most of the time, canned food is even fresher than the fruits and vegetables you buy at the supermarket.
Many canning factories will set up their own planting bases near the factories. Let’s take canned tomatoes as an example: in fact, it takes less than a day to pick, make and seal tomatoes. How can they be fresher than most fruits and vegetables in a short time! After all, before consumers bought it, the so-called fresh fruits and vegetables had already experienced the 9981 difficulty and lost a lot of nutrients.edit In fact, most canned food is more nutritious than the fresh food you eat
2.So long shelf life, what’s going on?
We have already mentioned one of the reasons for the long shelf life of cans, that is, vacuum environment, and the second is high temperature sterilization. High temperature sterilization, also known as pasteurization, allows high temperature sterilized food to no longer contact with bacteria in the air, which is called preventing food from being contaminated by bacteria from the source.
3. Canned food is certainly not as nutritious as fresh food!
Lack of nutrition is the second reason why consumers refuse to buy canned food. Is that canned food really nutritious? In fact, the processing temperature of canned meat is about 120 ℃, the processing temperature of canned vegetables and fruits is not more than 100 ℃, while the temperature of our daily cooking is more than 300 ℃. Therefore, the loss of vitamins in the process of canning will exceed the loss in frying, frying, frying and boiling? Moreover, the most authoritative evidence to judge the freshness of food is to see the degree of original nutrients in food.
