I have made juice of Orange, Apple & Mango; with Sodium benzoate as 0.2% with 12% sugar , but it is failed within 45months.
What may be reason for the same it has following problems observed?
(1)PET Bottle have gas formation(100% bottles)
(2)90% bottles have bad smell
(3)White and light green coloured fungus observed after 45days( in 80% bottles)
Let’s start with the basic: check the condition, reception, selection, etc, of the fruits and other materials in the plant
The hygiene of all the people and equipment , etc, involved in the process
The processes used for preparing fresh-cut fruits can induce mechanical injury in the tissue accelerating deterioration.
Desinfectation of the fruits before
Conditions of storage
Every aspect of the process counts
Thanks a lot, this is useful & will apply; but the main part of my query i.e. 90% of quarry is pending, if you can give some knowledge like How to make, means how to prepare, means how shelf life will achieve , if thermal sterilisation needs than when? before filling or after filling overall process ; because the problem observed was may be our faulty process, like we have sterilise it 90seconds at 75Deg.Centigrade in PET Bottle and sealed.
yes 80 degree second time for 90 seconds.
so maybe there is a problem about pasteurization effeciency.
Did you check it?
