The shelf life of freshly squeezed juice is affected by many factors, including the composition of the juice, storage conditions and temperature. In general, freshly squeezed juice can only be stored for 1-2 hours at room temperature, because the vitamins and nutrients in the juice gradually lose their activity over time. At the same time, sugars such as fructose and glucose in the juice are also broken down by microorganisms such as bacteria and yeast at room temperature, resulting in the deterioration of the juice.
In order to extend the storage time of freshly squeezed juice, some preservation methods can be employed. First of all, the juice can be refrigerated in the refrigerator, which can slow down the growth and reproduction of microorganisms in the juice and extend the storage time of the juice. In the refrigerator, the storage time of the juice can be extended to 4-6 hours.
Secondly, it can be sealed in an airtight container, which can avoid air contact with the surface of the juice, slow down the oxidation and deterioration of nutrients in the juice, and extend the storage time of the juice. In an airtight container, the storage time of the juice can be extended to 6-8 hours.
It should be noted that the juice is best opened before drinking to avoid oxidation and deterioration of the nutrients in the juice. At the same time, if the juice has deteriorated, there will be peculiar smell or taste changes, and it should be discarded in time to avoid affecting human health.
