Due to the extremely high concentration and high osmotic pressure of honey, the cells entering it will be severely dehydrated and die, so honey will not deteriorate and there is no need to add preservatives. Really mature honey is completely edible after being stored for a long time, and there is no strict shelf life.
Honey or honey products must have a shelf life marked on the food according to the Food Law. Therefore, honey manufacturers generally set the shelf life of honey at 2 years or 18 months.
Extended information
Native honey is also called wild honey, commonly known as native bee sugar. It is made by Chinese bees collecting a variety of nectar. It is also called Chinese bee sugar. The output is scarce and it is free of pollution in mountainous areas. Compared with other honeys, it has better effects in beauty, weight loss and health maintenance. Traditionally raised bumblebees are collected once a year.
1. There are white bubbles on the surface of unprocessed honey. This is because the antibacterial substance hydrogen peroxide produced by the glucose in the honey under the action of oxidase. The hydrogen peroxide easily decomposes into oxygen, thus leaving a very thin layer on the surface of the honey. Fine white bubbles.
When we see foam on the surface of honey, it proves that it is unprocessed natural honey. However, honey that has been concentrated and processed generally does not produce foam because its active enzymes have been destroyed. If we skim off the foam on the surface of the honey, it will appear again soon. Shake the honey bottle vigorously and the foam will increase.
2. After the unprocessed honey is shaken or stirred, a large number of small and even bubbles will appear in the honey. This is because the forager bees return the nectar to the housekeeping bees, and the housekeeping bees spit the nectar at the end of their mouths. It forms small bubbles and flaps its wings to cause the water in the bubbles to evaporate.
The longer the house bees make honey, the more bubbles there will be in the honey. Stirring or shaking can restore the small bubbles in the honey to their original state.
