Stored at room temperature: not more than 2 hours, more than 2 hours, freshly squeezed juice will breed a large number of microorganisms, microbial overload, which will cause discomfort to the consumer, such as diarrhea. So at room temperature, not more than 2 hours.

Refrigerator storage: 6-8 hours in summer, 12-24 hours in winter. If put in the refrigerator should not exceed 24 hours at most. Freshly squeezed juice is usually ready to drink, it is best to drink within half an hour is better, do not store.

If there is no boiling, the juice should be drunk immediately after extraction, can not be stored. It can be said that the loss of vitamins and antioxidants increases with every minute. If the enzymes have been inactivated after blanching and rejuicing, then a day of closed storage in the refrigerator should be possible. But be careful to minimize contact between the juice and air to avoid oxidative browning.

Juice that has been blanched is very susceptible to browning. Browning does not mean that it is toxic or harmful, you can still drink it, but it just means that the polyphenols in the fruit and vegetables are oxidized when they come into contact with oxygen, and the antioxidant effect will be reduced. At the same time, in storage, the flavor will gradually change, losing the original fresh taste.

Pre-squeeze hot to save nutrients

Many people do not know that commercial production of fruit and vegetable juice, often to fruits and vegetables for hot treatment. In other words, the fruits and vegetables need to be slightly scalded in boiling water to "kill" the oxidizing enzymes and make the tissues a little softer before juicing.

This not only reduces the loss of vitamins and increases the yield of the juice, but also makes the juice colorful and less prone to browning. Especially those vegetables without acidic flavor, such as carrots, bok choy, celery, fresh sweet corn, must be blanched before juicing.

As for the kind of satiety of complete vegetables and fruits, it is not retained no matter how to juice. So dieters are better off with a complete meal, juicing is not the ideal choice.
