Mixed Fruit Juice Manufacture
Practical Action
Make the pieces into fruit pulp by liquidising or passing through a Kenwood colander/sieve (large
aperture). The juice can be separated from the pulp by squeezing it through a muslin cloth.
Dissolve the sugar in the water and filter through a muslin cloth (sugar often contains dirt and
foreign bodies). Heat the sugar and water to 95°C and then add the rest of the ingredients to the
hot mixture (heating the sugar and water first, means that the fruit juice is heated up to
temperature very quickly up to temperature and so reduces the loss of the sensitive flavour).
Heat all the ingredients until the temperature reaches 90°C, hold at that temperature for one
minute, then start the filling operation. It is important that the temperature is maintained as
close to 90°C as possible.
The fruit juice should be filled into bottles which have been cleaned and then steamed to
sterilise them, and are still hot so that the bottles do not crack. The bottles should be filled as
quickly as possible so that the juice is not heated for longer than necessary, or re-contaminated
because it has cooled down before being sealed in the bottle. The lip of the bottle should be
clean and dry (wipe with clean tissue paper) before placing the cap on it. Lay the bottles on
their side for 15 minutes to cool. Cooling on their side is a most important step to avoid
contamination while the cap fits firmly down onto the glass as the vacuum forms.
