摘要

Production of a melon extract includes washing and cleaning freshly picked melons, crushing the whole melons and centrifuging them. The juice produced is frozen, defrosted and concentrated by ultrafiltration to give an extract with 95 - 99% dry matter. The extract can be stored at ambient temperature prior to use. Independent claims are included for the following: (a) Melon extract produced as above. (b) A device for producing the above melon extract. Preferred Features: The cleaned melons are frozen and defrosted before being crushed. Ultrafiltration is a reverse osmosis performed at 1- 2 millibars and 20 deg C followed by sublimation at - 70 deg C. The extract is diluted in glucose syrup.
