1. Raspberries can be kept fresh at low temperature

Putting fresh raspberries in a quick-freezer can preserve the color, aroma and flavor of the fruit to the greatest extent. Take them out of the refrigerator when you want to eat them, so that even if the raspberries thaw, the berry cells will not be lost too much.

2. Raspberries can be preserved by chemical methods

Raspberries are easily attacked by microorganisms and moldy. At this time, we can use chemical agents to inhibit the growth of mold, and we can use yeast to store and preserve it, which is more efficient.

3. Raspberries can be kept fresh using ozone

Ozone itself has the following effects: First, it inhibits the growth of mold on the surface of fruits and vegetables, thereby extending the shelf life of fresh fruits and vegetables. Second, ozone can eliminate and inhibit the volatilization of substances such as ethylene. Third, ozone will induce the gradual reduction of stomata on the fruit skin, reducing water evaporation internally and preventing the invasion of foreign bacteria externally.
