3. Preservation by freezing is carried out at about -30deg C, after a preliminary de-aeration; storage is at -15 to -20deg C.

Note: Care is needed when producing pineapple juice due to a heat resistant enzyme in the juice. The enzyme damages skin after prolonged contact and workers should therefore wear gloves to protect their hands. The juice must be heated to a higher temperature for a longer time to destroy the enzyme (eg boiling for 20 minutes).
Small scale production packaging can be done cost effectively with plastic bottles, plastic bags that need sealing, and cups that need sealing. For cups using the foil heat sealed lids is adequate and can be done cost effectively to begin with by using a hot iron before upgrading to a more commercial hand sealer.
- Pay particular attention to the quality of re-usable bottles, check for cracks, chips etc and wash thoroughly before using. If bottles are not able to be sterilized with hot water as in the case of plastic bottles, they can be sterilised in cold water using the sterilising agent Calcium Hypochlorite.
- The concentration of preservative should be carefully controlled for correct preservation of squashes and cordials, and may be subject to local laws. Check first and use accurate scales to measure the preservative.
- The temperature and time of heating are critical for achieving both the correct shelf life of the drink and retaining a good colour and flavour. A thermometer and clock are therefore needed.
- Standardisation of products is a must therefore the correct weight should be filled into the bottles each time

Shrink wrapping is used to ensure security on lids of products as well as for labelling. Heat in the form of hot air or hot water is used to shrink a plastic film around the top of bottles or entire bottles when used for labelling. The end products look very professional. The advantages of labelling this way allow one to purchase generic empty packaging as in bottle or cups and then label in batches as needed rather than going through the process and cost of labelling minimum volumes of printed packaging which can be prohibitively expensive for the small scale and start up produce.
